The network slice can be a complete end-to-end network including terminal equipment, access network, transmission network, core network, and service server, or it can include only the core network but supplemented by terminal equipment, access network, transmission network, and A business server can provide complete communication services with certain network capabilities. Network slicing can be a communication resource that guarantees that a bearer service or service can meet the requirements of a service level agreement, or it can be considered as a place to complete a certain communication service or some communication service The combination of required network functions and communication resources. A network slice is identified by a single network slice selection assistance information (single network selection information, S-NSSAI). The S-NSSAI consists of a slice / service type (SST) and a slice differentiator (SD). Among them, SST and SD can be defined by the standard or customized by the operator; SD is optional information that supplements SST to distinguish multiple network slices of the same SST, for example, it can be used to characterize the ownership relationship of network slices.

A network slice instance (NSI), also known as a slice instance network, is an instantiated network created by an operator on the infrastructure according to a network slice template, which is a collection of different network functional entities and physical resources. Logical isolation between different network slice instances. A network slice can instantiate one or more NSIs, and each NSI is identified by a network slice instance identifier (NSI ID). That is, one S-NSSAI corresponds to one or more NSI IDs.

Network slice sub-instances (NSSI), also known as slice sub-instance networks, are a set of network functional network elements and the arrangement and configuration of the resources of these functional network elements. They are used to form a local logical network. The network slice sub-instance is mainly to facilitate the management of a network slice instance. For example, the network slice is divided into two network slice sub-instances according to the core network element and the access network element. Easy to manage.

Service level agreement (SLA): A contract between a service provider and its customer, used to record application services provided by the service provider, and define the performance standards that the service provider provider is obligated to meet. SLAs can build customer expectations for service providers in terms of performance and quality. SLA can include a series of qualitative or quantitative details such as availability, performance indicator baseline, reliability, and response time.

For example, the network element of the access network may be a 5G base station or a next generation base station (gNB), an evolved base station (eNodeB), or a wireless fidelity access point (WiFi AP), or It is a global microwave access interoperability base station (worldwide microwave access base station, WiMAX BS), or a wireless controller in a cloud radio access network (CRAN), or the network equipment may be for the future Evolving access network equipment in PLMN, etc.

The PCF network element has the function of policy control and decision making, and provides a policy for the network. AMF network elements are used for mobility management, lawful interception, or access authorization and authentication. SMF network elements are used to implement session and bearer management, address allocation, and so on. User plane function network elements are used for user plane data routing and forwarding, threshold control, traffic monitoring, verification and other functions. The network storage function network element is used to provide a service discovery or network element discovery function, and to maintain the characteristics of the network element and the functions supported by the network element. The transmission network element has the function of transmitting network data. For example, the transmission network element may be a routing repeater.

The network operation and maintenance management (OAM) network element or NSMF network element has network management functions, including deployment and setting of network (such as network slice or network slice instance), device-level or network-level performance parameter measurement statistics, fault monitoring, fault declaration , Fault location, and fault repair.

NWDAF has data statistics and analysis functions, which can be used to collect and analyze relevant data from network network elements, third-party service servers, terminal equipment or network management systems, and provide terminal equipment to network network elements, third-party service servers, and terminal equipment based on the relevant data Or the network management system provides data analysis results. The analysis results can assist the network in selecting service quality parameters of the business, or assist the network in performing traffic routing, or assist the network in selecting background traffic transmission strategies. In the embodiment of the present application, the data analysis device may be further configured to provide a network (for example, a network slice or a network slice instance) analysis result, so that the network performs deployment or adjustment of the network (for example, a network slice or network slice instance) according to the analysis result Internet resources.

Network Capabilities The open network element NEF has the function of providing or opening the functions of the operator's network to external servers or external devices, and it acts as an intermediate medium for internal and external communications within the network. For example, when a third-party untrusted service server needs to communicate with the network, it needs to forward and process network elements through network capabilities to open network elements. Of course, if it is an internal service server or a third-party trusted service server that communicates with the network, the network elements can be opened without going through network capabilities.

In the embodiments of the present application, all or part of the network elements of the access network device and the core network may belong to a 3rd generation partnership project (3GPP) network, or may belong to a non-3GPP network, for example, an enterprise The internet. All or part of the network elements of the core network may be physical physical network elements or virtualized network elements, which is not limited herein.

The network applied by the resource management method provided in the embodiment of the present application may be a network slice (for example, a slice in a 5G network), or a network slice instance in the network slice (for example, a network slice instance in a 5G network slice), or A 4G network corresponding to a dedicated core network (DCN), or other granular network, such as a network distinguished by a PLMN identifier, etc., is not specifically limited in this embodiment of the present application.

That is, the data analysis network element in this application may include, but is not limited to, NWDAF. The data analysis network element may be a network element located on the control plane of the core network and having the data analysis function according to the present invention, or a network element located on the network management plane and having the data analysis function according to the present invention.

For example, the network management network element in this application may include, but is not limited to, OAM and NSMF.

In addition, the data analysis function and other functions can be combined and deployed on the same network element. For example, the data analysis function and the policy control function may be combined and deployed, the data analysis network element and the policy control network element are physically the same entity. Similarly, the data analysis function and the network management function can be combined and deployed on the same network element, so the data analysis network element and the network management network element are physically the same entity.

In addition, this application does not limit whether the policy control function and the network management function involved in the present invention are deployed together. When the two are deployed together, the policy control network element and the network management network element are actually the same network element. For example, they are both network management network elements or policy control network elements.

In addition, the service quality referred to in the embodiments of the present application may also be referred to as a service experience.

201. A policy control network element sends request information to a data analysis network element, where the request information is used to request network configuration information corresponding to the sliced network list. Correspondingly, the data analysis network element receives the request information sent by the policy control network element. The slice network list may include one or more slice networks.

In some embodiments, the request information may include an identifier of one or more slice networks included in a slice network list. When the slice network list includes a slice network, the request information includes an identifier of a slice network; when the slice network list includes multiple slice networks, the request information includes an identifier of the multiple slice networks. The slicing network identifier can be S-NSSAI, NSI ID, NSSI ID, etc. After receiving the identification of the slice network included in the slice network list, the data analysis network element can determine the service quality requirements of the slice network list according to the correspondence between the slice network list and the service quality requirement. The correspondence between the slice network list and the service quality requirements may be pre-configured in the data analysis network element, or may be sent to the data analysis network element by other network devices or tenants. For example, the policy control network element may send the service quality requirements corresponding to all slice networks to the data analysis network element. After the data analysis network element receives the request message sent by the policy control network element, it may query or map out the request message. The service quality requirements of each slice network in the included slice network list, and the service quality requirements of each slice network constitute the service quality requirements of the slice network list.

For example, Table 1 is the correspondence between a list of sliced networks and quality of service requirements.

Table 1

切片网络标识Slice network identification	业务质量要求Quality of service requirements
切片网络1Slicing network 1	MOS>3的用户比例>95％Proportion of users with MOS> 3> 95%
切片网络2Slicing Network 2	MOS>3的用户比例>90％Proportion of users with MOS> 3> 90%
切片网络3Slicing network 3	MOS>3的用户比例>85％Proportion of users with MOS> 3> 85%

The slice network list shown in Table 1 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. Each of the three slice networks corresponds to the quality of service requirements of a slice network. Specifically, the service quality requirement of the slice network may be a user satisfaction requirement of a service in the slice network, where the user satisfaction of the service refers to a proportion of users who meet the single user service quality requirement of the service. As shown in Table 1, the service quality requirement corresponding to slice network 1 is a voice service average opinion score (MOS) greater than 3 and the proportion of users greater than 95%; the slice network 2 corresponding service quality requirement is a voice service MOS greater than 3 The proportion of users of the service is greater than 90%; the service quality requirement corresponding to the slice network 3 is that the proportion of users of the voice service MOS greater than 3 is greater than 85%. It can be understood that a MOS greater than 3 points is an example of a single user service quality requirement for a voice service, that is, for each individual user, a MOS for a voice service is required to be greater than 3 points. The proportion of users with a MOS greater than 3 is greater than 95%, which indicates that the voice service MOS of more than 95% of the users in the slice network is greater than 3 points.

In addition to the user satisfaction requirements of the services in the slicing network described above, the service quality requirements of the slicing network may include other requirements or be other requirements. For example, the service quality requirements of a slice network may also include the number of users in the slice network, where the number of users in the slice network refers to the number of registered users or online users in the slice.

The slice network list in the request information sent by the policy control network element may include the identities of slice networks 1 to 3. After the data analysis network element has obtained the request information, it can determine the service quality requirements corresponding to each slice network according to the corresponding relationship in Table 1.

Further, in other embodiments, in addition to the identification of the slicing network included in a slicing network list, the request information may further include a service identification corresponding to all or part of the services of each slicing network identification. After receiving the identification and service identification of the slice network included in the slice network list, the data analysis network element can determine the service quality requirements of the slice network list according to the correspondence between the slice network list and the service quality requirement. The correspondence between the slice network list and the service quality requirements may be pre-configured in the data analysis network element, or may be sent to the data analysis network element by other network devices or tenants. Before sending the request message, the policy controls the network element to determine the identifier of the slice network and the service identifier included in the slice network list according to the priority information and service priority information of the slice network.

In some embodiments, the request information may further include quality of service requirements of a sliced network list.

In some embodiments, the slice network list may include only one slice network. In this case, the service quality requirements of the slice network list include the service quality requirements corresponding to the one slice network.

In other embodiments, the slice network list may include multiple slice networks. In this case, the service quality requirements of the slice network list include the service quality requirements corresponding to each slice network in the multiple slice networks.

The network configuration information corresponding to the slice network list can meet the service quality requirements of the slice network list. Specifically, when the network management device performs network configuration on each slice network in the slice network list according to the network configuration information corresponding to the slice network, the services in the slice network can satisfy each slice. Quality of service requirements for the network. In other words, if the service quality requirements of the slice network list include the service quality requirements of a slice network, the network configuration information corresponding to the slice network list can meet the service quality requirements of the slice network. Specifically, when the network management device performs network configuration according to the network configuration information corresponding to the slice network list, the services in the slice network can meet the service quality requirements corresponding to the slice network; if the service quality requirements of the slice network list include The service quality requirements corresponding to each slice network in the multiple slice networks, then the network configuration information corresponding to the slice network list can meet the service quality requirements corresponding to each slice network. Specifically, when the network management device performs network configuration according to the network configuration information corresponding to the slice network list, each slice in the slice network list is a service in the network and can meet service quality requirements corresponding to each slice network.

In some embodiments, the service quality requirements of the slice network list may include multiple service quality requirements, and each of the multiple service quality requirements is a service quality requirement corresponding to a slice network. In this case, the quality of service requirement of the slice network list may include the identifier of the slice network in addition to the quality of service requirement. In other words, the service quality requirements of the slice network list may include identifiers of N slice networks and N service quality requirements. The identifiers of the N slice networks correspond to the N service quality requirements one by one, and N is greater than or A positive integer equal to 1. One of the service quality requirements in the service quality requirements of the slice network list is the service quality requirements corresponding to the corresponding slice network. For example, the above Table 1 may also be a schematic diagram of the service quality requirements of the sliced network list.

Further, the service quality requirements of the three slice networks shown in Table 1 are all the service quality requirements of the same service (that is, the voice service). In some embodiments, the services corresponding to different slice networks in the slice network list may be different. For example, in the service quality requirements of the slice network list, one slice network corresponds to a voice service, and the other slice network corresponds to a data service.

Further, even if different slice networks provide the same service, the single user service quality requirements for the service may be different. For example, the single user service quality requirements of the voice services corresponding to the three different slice networks in Table 1 may also be different, which may be determined through negotiation between the tenant network and the operator network of the slice network. For example, the single-user service quality requirement for voice services in slice network 1 is MOS> 3, and the single-user service quality requirement for voice services in slice network 2 is MOS> 4.

In some embodiments, the service quality requirements corresponding to each slice network include the service quality requirements of at least one service in each slice network.

If the service quality requirement corresponding to each slice network includes only the service quality requirement of one service in each slice network, the service quality requirement corresponding to each slice network may include the identification of the slice network and the service quality requirement. The service quality requirement corresponding to each slice network may further include service identification information of the service. In the case that the service quality requirement corresponding to each slice network does not include the service identification information of the service, the content of the service quality requirement corresponding to each slice network may be shown in Table 1.

If the service quality requirements corresponding to each slice network include service quality requirements for multiple services, the service quality requirements corresponding to each slice network may include each service quality in addition to the identification of the slice network and the service quality requirements. The identity of the corresponding service is required. In other words, the service quality requirements of the slice network list may include identifiers of N slice networks, and the identifiers of each slice network in the identifiers of the N slice networks correspond to the identifiers of M services and the M service quality requirements. The M service quality requirements are in one-to-one correspondence with the M service identifiers, and each of the service quality requirements in the service quality requirements of the slice network list is the service quality requirements of the corresponding service. For example, Table 2 is an illustration of the quality of service requirements for a sliced network list.

Table 2

The slice network list shown in Table 2 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each of the three slice networks includes the service quality requirements of two services. For example, the slice network 1 includes the service quality requirements of video services and the service quality requirements of voice services. The service quality requirements of video services are that the user satisfaction of video services is greater than 95%, and the user satisfaction of video services refers to the average opinion of video. The percentage of users with a video score (vMOS) greater than 4 points. The service quality of the voice service requires the user satisfaction of the voice service to be greater than 95%. The user satisfaction of the voice service refers to the proportion of users with a MOS greater than 3. It can be understood that a vMOS score greater than 4 is an example of single user service quality requirements for video services, that is, for each individual user, a vMOS score of video services is required to be greater than 4 points; a MOS score greater than 3 is a single user service quality requirement for voice services An example is that for each individual user, the MOS of the voice service is required to be greater than 3 points. The proportion of users with vMOS greater than 4 is greater than 95%, which means that the vMOS of the video service for more than 95% of the users in the slice network is greater than 4 points. The proportion of users with a MOS greater than 3 is greater than 95%, which indicates that the voice service MOS of more than 95% of the users in the slice network is greater than 3 points.

In the example shown in Table 2, the service quality requirement corresponding to a service is a service quality requirement. In other embodiments, the service quality requirements corresponding to one service may also be multiple service quality requirements. Furthermore, the number of service quality requirements corresponding to different services may also be different. Table 3 is a schematic diagram of service quality requirements of a slice network, where multiple service quality requirements of a service refer to service user satisfaction requirements corresponding to multiple single-user service quality intervals.

table 3

The slice network list shown in Table 3 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each of the three slice networks includes the service quality requirements of two services. For example, the slice network 1 includes service quality requirements for video services and service quality requirements for voice services. In the three slice networks shown in Table 3, each slice network includes two services, and the two services have different service quality requirements. Specifically, the service quality requirements of the video service included in the slice network 1 include 3 service quality requirements, the service quality requirements of the voice service included in the slice network 1 include 2 service quality requirements, and the service quality requirements of the video service included in the slice network 2 Includes 2 service quality requirements. The service quality requirements for the voice service included in the slice network 2 include 1 service quality requirement. The service quality requirements for the video service included in the slice network 3 includes 1 service quality requirement. The voice service included in the slice network 2 includes. The quality of service requirements include 2 quality of service requirements.

In addition, it can be seen that the number of service quality requirements corresponding to the same service in different slice networks may also be different. Specifically, the video service corresponds to 3 service quality requirements in slice network 1, 2 service quality requirements in slice network 2, and 1 service quality requirement in slice network 3. The voice service corresponds to 2 in slice network 1. Each service quality requirement corresponds to one service quality requirement in slice network 2 and two service quality requirements in slice network 3.

In some embodiments, the quality of service requirements corresponding to each slice network include quality of service requirements corresponding to at least one user type in each slice network.

If the service quality requirements corresponding to each slice network include only the service quality requirements corresponding to one user type in each slice network, the service quality requirements corresponding to each slice network may only include the identification of the slice network and the service. Quality requirements. In this case, the content of the service quality requirements corresponding to each slice network can be shown in Table 1. Further, in some embodiments, even if the service quality requirement corresponding to each slice network includes only the service quality requirement corresponding to one user type in each slice network, the service quality requirement corresponding to each slice network may be It further includes a user type identifier.

If the service quality requirements corresponding to each slice network include the service quality requirements corresponding to multiple user types, the service quality requirements corresponding to each slice network may include, in addition to the identification of the slice network and the service quality requirements, each User type identifier corresponding to the quality of service requirement. In other words, the service quality requirements of the slice network list may include identifiers of N slice networks, and the identifiers of each slice network in the identifiers of the N slice networks correspond to M user types and M service quality requirements. The M service quality requirements correspond to the M user types on a one-to-one basis, and each of the service quality requirements in the service quality requirements of the slice network list is the service quality requirements corresponding to the corresponding user type. For example, Table 4 is an illustration of the quality of service requirements for a sliced network list.

Table 4

The slice network list shown in Table 4 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each of the three slice networks includes the service quality requirements corresponding to the two user types. For example, the slicing network 1 includes the service quality requirements corresponding to the gold user and the service quality requirements corresponding to the silver user. The service quality requirement corresponding to the gold user is 95% of the users with a MOS greater than 3 points, and the service quality requirement corresponding to the silver user. In order to reach MOS greater than 3, the proportion of users is 90%.

In some embodiments, the service quality requirements corresponding to each slice network may include service quality requirements corresponding to at least one user type in one or more services in each slice network.

In other words, in some embodiments, the service quality requirements corresponding to each slice network may include the service quality requirements of a service of a user type in each slice network. In this case, the content of the service quality requirements of the slice network list can be shown in Table 1. In addition to the contents shown in Table 1, the content of the service quality requirements of the slice network list may further include a user type identifier and / or a service identifier.

In other embodiments, the service quality requirements corresponding to each slice network may include service quality requirements for multiple services of one user type in each slice network. In this case, the content of the service quality requirements of the slice network list can be shown in Table 2. In addition to the content shown in Table 2, the content of the service quality requirements of the sliced network list may also include a user type identifier.

In other embodiments, the service quality requirements corresponding to each slice network may include service quality requirements for one service of multiple user types in each slice network. In this case, the content of the service quality requirements of the slice network list can be shown in Table 4. In addition to the content shown in Table 4, the content of the service quality requirements of the slice network list may also include a service identifier.

In other embodiments, the service quality requirements corresponding to each slice network list may include service quality requirements corresponding to multiple user types in multiple services in each slice network. For example, Table 5 is an illustration of the quality of service requirements for a sliced network list.

table 5

The slice network list shown in Table 5 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each slice network in the three slice networks includes two services, and each service includes service quality requirements corresponding to two types of users. For example, the slicing network 1 includes service quality requirements corresponding to gold users of voice services, service quality requirements corresponding to silver users of voice services, service quality requirements corresponding to gold users of video services, and service quality requirements corresponding to silver users of video services. The service quality requirement for the gold user of the voice service is that the satisfaction of the gold user of the voice service is greater than 95%. The satisfaction of the gold user of the voice service means that for the type of gold user, the user with a MOS of the voice service greater than 3 points accounts for the gold. The proportion of the total number of users. The corresponding service quality requirement of the silver user of the voice service is that the satisfaction of the silver user of the voice service is greater than 90%. The silver user satisfaction of the voice service refers to the MOS of the voice service for the type of silver user. The proportion of users greater than 3 to the total number of silver users is greater than 90%. The corresponding service quality requirement for the gold users of the video service is that the satisfaction of the gold users of the video service is greater than 95%. The satisfaction of the gold users of the video service refers to the gold users. In terms of type, the vMOS of the video service is greater than 4 points Of users who account for the total number of gold users. The corresponding service quality requirement for the silver users of this video service is that the silver user satisfaction of the video service is greater than 90%. The silver user satisfaction of the video service refers to the video service for the type of silver user The proportion of users with vMOS greater than 4 accounts for the total number of silver users.

In some embodiments, the quality of service requirements corresponding to each slice network may include the quality of service requirements of one or more spatial information in each slice network. The spatial information may be spatial information defined in a 3GPP communication network, such as serving cell A or registration area B. The spatial information may also be spatial information defined in a non-3GPP communication network, such as the spatial information is a specific geographical location range ( For example, latitude and longitude or global positioning system (Global Positioning System (GPS) spatial information). For example, Table 6 illustrates the quality of service requirements for a sliced network list.

Table 6

The slice network list shown in Table 6 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each of the three slice networks includes the service quality requirements of the two regions. For example, each of the slicing network 1, the slicing network 2, and the slicing network 3 includes the service quality requirements of area 1 and the service quality requirements of area 2.

Table 6 illustrates that one spatial information corresponds to one quality of service requirement. In other embodiments, one spatial information may also correspond to multiple quality of service requirements. For example, the service quality requirements of a spatial information may be multiple service quality requirements of the same service; for another example, the service quality requirements of a spatial information may be the service quality requirements of multiple services.

The number of service quality requirements and / or service quality requirements for different spatial information may also be different.

In some embodiments, the service quality requirements corresponding to each slice network may include service quality requirements of one or more time information in each slice network. The specific form of the time information is not limited in the embodiments of the present application, as long as the time information can reflect time. For example, the time information may be divided on an hourly basis, for example, the first time information is from 8 to 10 o'clock, and the second time information is from 10 to 12 o'clock. As another example, the time information may also be divided on a day basis, for example, the first time information is from the 1st to the 10th of each month, and the second time information is from the 11th to the 20th of each month. As another example, the time information may also be divided by the length of time the user is turned on. For example, the first time information is 0 to 4 hours after being turned on, and the second time information is 4 to 8 hours after being turned on. For example, Table 7 illustrates the quality of service requirements for a sliced network list.

Table 7

The slice network list shown in Table 7 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each of the three slice networks includes the service quality requirements of two time information. For example, each of the slicing network 1, the slicing network 2, and the slicing network 3 includes a service quality requirement of the time information 1 and a service quality requirement of the time information 2.

Table 7 illustrates that one time information corresponds to one service quality requirement, while in other embodiments one time information may correspond to multiple service quality requirements. For example, the service quality requirements of one time information may be multiple service quality requirements of the same service; for another example, the service quality requirements of one time information may be service quality requirements of multiple services.

The number of service quality requirements and / or service quality requirements for different time information may also be different.

The service quality requirements of the sliced network list shown in Table 2, Table 4, Table 3, Table 6, and Table 7 are all one-dimensional service quality requirements of the sliced network list. Specifically, Tables 2 and 3 are the service quality requirements of the service type dimension of the sliced network list, Table 4 is the service quality requirements of the user type dimension of the sliced network list, and Table 6 is the service quality requirements of the spatial dimension of the sliced network list. Table 7 shows the quality of service requirements in the time dimension of the sliced network list.

Any two or more of the business type dimension, user type dimension, spatial dimension, time dimension, and business quantity dimension can be combined to obtain the service quality requirements of multiple dimensions of the sliced network list. For example, Table 8 shows the service quality requirements of the sliced network list obtained by the combination of the business dimension and the user type dimension.

Table 8 shows the service quality requirements of the slice network list obtained by combining the service type dimension and the spatial dimension.

Table 8

The slice network list shown in Table 8 includes three slice networks, and the three slice networks are slice network 1, slice network 2, and slice network 3, respectively. The service quality of each slice network in the three slice networks includes two services, and each service includes service quality requirements in two regions. For example, the slice network 1 includes the service quality requirements of area 1 of the voice service, the service quality requirements of area 2 of the voice service, the service quality requirements of area 1 of the video service, and the service quality requirements of area 2 of the video service.

Although one area of one service type of one slice network in Table 8 has only one quality of service requirement, the number of service quality requirements in one area of one service type of one slice network is not limited in the embodiment of the present application. In other words, a region of a service type of a slice network may include multiple service quality requirements.

Tables 1 to 8 are described by using only voice services and video services as examples. Actually, other different types of services may exist in a slice network, which is not limited in the embodiments of the present application. In addition, the service quality requirement of a service is the requirement for the proportion of users who meet the single user service quality requirement of the service. Here, the requirement of the proportion of users who meet the single user service quality requirement of the service can also be referred to as the user satisfaction of the service Degree requirements. Single-user service quality refers to data that evaluates the service experience of each user. The specific method of how to evaluate the service experience of each user can be determined by the service provider. For example, the voice service server decides to use MOS to evaluate the single-user voice service quality. The value range of MOS score is [0,5]. The higher the MOS score, the better the user's voice service experience. How to calculate the MOS score of each user belongs to an internal calculation method, which is outside the scope of this patent. For video services, the video service server decides to use vMOS score to evaluate each user's video service experience. The calculation method of MOS score and vMOS is different. Here, the evaluation of single-user service quality using MOS points and vMOS is just two examples for voice and video services. For other types of services, there are many other methods for evaluating single-user service quality. For example, for data services, it is possible Using the parameters such as data packet loss rate and average delay of data packet transmission to comprehensively evaluate the service quality of a single user of a data service, this patent is not limited. In addition, the preset single-user service quality requirements are negotiated in advance by the operator and the service provider. For example, for voice services, the single-user service quality requirements can be preset to MOS> 3.

In addition, in some cases, a single user initiates only one service of the same service type. In this case, the number of services is equivalent to the number of users executing the service. Therefore, the user satisfaction requirement of a service is the proportion of users who meet the single user service quality requirements of the service. In other cases, a single user can initiate multiple services of the same service type. For example, a user can initiate two voice services simultaneously. In this case, the number of services is not equivalent to the number of users executing the service. The user satisfaction requirement of a service may be a service proportion requirement that meets the single user service quality requirement of the service. For example, suppose there are a total of 1,000 users, and each user initiates two voice services at the same time. At this time, there are a total of 2,000 voice services. The proportion requirement for MOS greater than 4 is the proportion requirement for MOS greater than 4. If each user initiates only one voice service, the service ratio requirement is equivalent to the user ratio requirement.

In addition, in all the previous examples, the service quality requirements of a service are described as an example of the proportion of users who meet the single user service quality requirements of the service as an example. Actually, the service quality requirements of a service are not limited to this. Other requirements can be included or included. For example, in addition to the requirement for the proportion of users for a single user service quality requirement, the service quality requirement for a service may also include the number of services required for the service, where the number of services requirement refers to the service for the service being executed in the slice network The total number of requirements, such as the requirement that the slice network be able to accommodate 10,000 voice services simultaneously. When it is assumed that one user can only perform one service of one service type at the same time, for example, one user can only perform one voice service at the same time, the number of services of one service is equivalent to the number of users who execute the service. In addition, if a service corresponds to multiple service quality requirements, in this scenario, the requirement for the number of services may be a requirement for the number of services corresponding to each service quality requirement. For example, taking Table 3 as an example, when multiple service quality requirements refer to service user satisfaction requirements corresponding to multiple single-user service quality intervals, then the service quality requirements of the service at this time may also include correspondences for each single-user service quality interval. Number of businesses required. It can be seen from this that the service quality requirement information of the service of the slice network mentioned in this application can actually be understood as the requirement for the overall service quality of the service in the slice network. Of course, in addition to the business satisfaction requirements, the service quality requirements of the slicing network services can also have other meanings, such as the average data transmission delay requirements of the slicing network services, the data throughput requirements of the slicing network, and the load requirements of the slicing network Wait.

The service quality requirements of the slice network list may also be in the form of any combination of slice networks in Table 1, Table 2, Table 4, and Table 5. For example, the quality of service requirements of the slice network list may be a combination of slice network 1 in Table 1, slice network 2 in Table 2, slice network 3 in Table 4, and slice network 3 in Table 5. This embodiment of the present application does not limit the combination of the slice network list sent by the policy control network element to the data analysis network element.

Further, as described above, Table 1 may be the correspondence between the slice network list and the service quality requirements, or may be the service quality requirements of the slice network list. Correspondingly, Tables 2 to 5 may also be the correspondence between the slice network list and the service quality requirements. Taking Table 2 as an example, if the request information includes the identifications of the slice network 1 to the slice network 3 in the slice network list, the data analysis network element may determine the corresponding one of the slice network 1 according to the corresponding relationship shown in Table 2. The service quality requirements include the service quality requirements of the video service and the service quality requirements of the voice service. The service quality requirements of the video service are that the user satisfaction of the video service is greater than 95%, and the service quality requirements of the voice service are that the user satisfaction of the voice service is greater than 95. %. Similarly, the data analysis network element may also determine the service quality requirements corresponding to the slice network 2 and the slice network 3 according to the correspondence relationship shown in Table 2.

In some embodiments, the policy control network element may determine the service quality requirements of the slice network list according to the slice network priority information. For example, the policy controls the network element to determine the slice network included in the slice network list according to the priority information, and then determines the service quality requirements corresponding to each slice network, where the service quality requirements corresponding to each slice network can come from each slice network The tenant or the corresponding service server can also be configured in the policy control network element. The operator network can provide and run multiple slicing networks at the same time. The multiple slicing networks have slicing network priority information, which guarantees that slicing networks can be configured or operated according to the slicing network priority information under special circumstances such as resource constraints. The priority of each slice network in multiple slice networks may be different, or some slice networks may have the same priority, which will be described below as an example.

Table 9 shows a slice network priority information including a total of 5 slice networks.

切片网络2Slicing Network 2	22

As shown in Table 9, the priority of slice network 1 is value 1, the priority of slice network 2 is value 2, the priority of slice network 3 is value 2, the priority of slice network 4 is value 3, and the priority of slice network The value is 4. It is assumed here that the larger the priority value, the lower the priority. As shown in Table 9, the priority value of the slice network 1 is the smallest, so the slice network 1 has the highest priority. The priority values of slice network 2 and slice network 3 are greater than the priority values of slice network 1, so the priorities of slice network 2 and slice network 3 are lower than the priorities of slice network 1. The priority value of the slice network 4 is greater than the priority value of the slice network 2, so the priority of the slice network 4 is lower than the priorities of the slice network 2 and the slice network 3. The slice network 5 has the highest priority value, so the slice network 5 has the lowest priority.

In some embodiments, the policy control network element may determine that the service quality requirements of the slice network list in the request information include the service quality requirements corresponding to several high-priority slice networks, that is, including a priority value less than a preset priority. The quality of service requirements corresponding to the valued slice network. Specifically, the preset priority value is set by a policy control network element according to a network resource state and an internal policy. For example, when network resources are sufficient or a specific value, the preset priority value may be set to a first priority value, and the first priority value may be a maximum value of the priority. In this case, the slice network list may be composed of all slice networks, and the service quality requirements of the slice network list in the corresponding request message may include service quality requirements corresponding to all slice networks. Taking Table 9 as an example, the first priority value may be 4. Assuming that the preset priority value is the first priority value, the slice network list is composed of slice networks with a priority value less than 4. The service quality requirements of the slice network list may include service quality requirements corresponding to slice networks with a priority value less than 4. The service quality requirements of the slice network list may include service quality requirements corresponding to the slice networks 1 to 5. When the network resource is limited or is another specific value, the preset priority value may be set as a second priority value, and the second priority value is smaller than the first priority value. In this case, the slice network list may consist of slice networks whose priority value is less than or equal to the second priority value, and the service quality requirements of the slice network list in the corresponding request message may include that the priority value is less than or equal to Quality of service requirements corresponding to the slice network of the second priority value. Taking Table 9 as an example, assuming that the preset priority value is 3, the service quality requirements of the slice network list in the slice network list may include service quality requirements corresponding to slice networks with priority values less than or equal to 3. In this case, the service quality requirements of the slice network list may include service quality requirements corresponding to slice network 1, slice network 2, and slice network 3.

The network resource status information can come from the network management network element. The status information can be qualitative status information or quantitative status information. For example, the policy control network element receives the instruction information of the network management network element before sending the request message in step 201. , The instruction information user informs the policy control control network element of the current network resource status. The policy controls the network element to set the specific value of the preset priority value according to the current network resource status.

The network resource status information may also be from a data analysis network element. The network resource status information is statistically analyzed by the data analysis network element during the historical process of the slice operation. For example, the data analysis network element statistically analyzes that the network resource is always insufficient in a certain period of time, resulting in failure to meet the service quality requirements of all slices. Then the data analysis network element can feed this information as network resource status information to the policy control network element, and then the policy control network element decides to request only certain high priority slices to form the slice network combination during this time period. The network resource status information can help the data analysis network element to generate applicable conditions corresponding to the network configuration information. The applicable conditions may include conditions such as when and where each group of network configuration information is applicable.

In addition, the network management network element may also determine the slice list or preset priority by itself, and request the policy control network element to provide the network configuration information applicable to the slice list or the slice list corresponding to the preset priority, and the policy control network element according to the The request from the network management network element directly sends a request message to the data analysis network element.

In some embodiments, the policy control network element determines the identity of one or more slice networks included in the slice network list included in the request information according to the priority information of the slice network. For a specific method, reference may be made to the description of the method for determining the slice network included in the slice network list according to the slice network priority information, and it is unnecessary to repeat it here.

In some embodiments, the policy control network element may determine the service quality requirements of the sliced network list according to the service priority information.

Table 10 is a schematic diagram of service priority information including a total of 5 services.

As shown in Table 10, the priority of service 1 is value 1, the priority of service 2 is value 2, the priority of service 3 is value 2, the priority of service 4 is value 3, and the priority of service is value 4. It is assumed that the larger the priority value, the lower the priority. As shown in Table 10, the priority value of service 1 is the smallest, so service 1 has the highest priority. The priorities of services 2 and 3 are greater than the priorities of service 1. Therefore, the priorities of services 2 and 3 are lower than the priorities of service 1. The priority value of service 4 is greater than the priority value of service 2, so the priority of service 4 is lower than the priority of services 2 and 3. Service 5 has the highest priority value, so service 5 has the lowest priority.

In some embodiments, the policy control network element may determine that the service quality requirement of the sliced network list in the request information includes a service quality requirement of a service whose service priority value is less than a preset priority value. Specifically, the policy control network element can determine which services can be included according to the service priority information, and then determine the service quality requirements of the slice network list according to the service quality requirements of each service included. The preset priority value is set by the policy control network element according to the network resource status and internal policies. For example, when network resources are sufficient or a specific value, the preset priority value may be set to a first priority value, and the first priority value may be a maximum value of the priority. In this case, the service quality requirements of all services may be requested, and the service quality requirements of the slice network list in the request message may include the service quality requirements of all services. Taking Table 10 as an example, the first priority value may be 4. Assuming that the preset priority value is the first priority value, the service quality requirements of all services can be requested. The service quality requirements of the slice network list may include service quality requirements of services with a priority value less than 4. The service quality requirements of the slice network list may include service quality requirements corresponding to services 1 to 5. When the network resource is limited or is another specific value, the preset priority value may be set as a second priority value, and the second priority value is smaller than the first priority value. In this case, a service quality requirement for a service whose priority value is less than or equal to the second priority value may be requested, and the service quality requirement for the slice network list in the corresponding request message may include a priority value less than or equal to the first Service quality requirements for services with two priority values. Taking Table 10 as an example, assuming that the preset priority value is 3, the service quality requirements of services with priority values less than or equal to 3 can be requested. In this case, the service quality requirements of the slice network list may include service quality requirements of service 1, service 2, and service 3.

In some embodiments, the policy control network element may determine the service quality requirements of the slice network list according to the slice network priority information and the service priority information.

Table 11 shows the priority information and service priority information of a slice network.

Table 11

As shown in Table 11, the priority value of slice network 1 is 1, the priority value of slice network 2 is 2, and the priority value of slice network 3 is 3. It is assumed that the larger the priority value, the lower the priority. As shown in Table 11, slice network 1 has the lowest priority value, so slice network 1 has the highest priority. The priority value of slice network 2 is greater than the priority value of slice network 1, so the priority of slice network 2 is lower than the priority of slice network 1. The slice network 3 has the highest priority value, so the slice network 3 has the lowest priority.

As shown in Table 11, the priority of service 1 is value 1, the priority of service 2 is value 2, and the priority of service 3 is value 3. It is assumed that the larger the priority value, the lower the priority. As shown in Table 11, the priority value of service 1 is the smallest, so service 1 has the highest priority. The priority value of service 2 is greater than the priority value of service 1, so the priority of service 2 is lower than the priority of service 1. Service 3 has the highest priority value, so service 3 has the lowest priority.

Specifically, the policy control network element may first determine the slice network included in the slice network list according to the slice network priority information, then determine the services that can request the service quality requirements according to the service priority information, and finally determine the service quality of the slice network list. Claim.

In some embodiments, the policy control network element may determine that the slice network list includes slice networks whose slice network priority value is less than a preset slice network priority value. For example, when network resources are sufficient or a specific value, the preset slice network priority value may be set to the first slice network priority value, and the first slice network priority value may be the largest slice network priority. value. In this case, the slice network list may consist of all slice networks. Taking Table 11 as an example, the first priority value may be 3. Assuming that the preset slice network priority value is the first slice network priority value, the slice network list is composed of slice networks whose slice network priority value is less than 3. When the network resource is limited or is another specific value, the preset slice network priority value may be set to a second slice network priority value, and the second slice network priority value is smaller than the first slice network priority value. In this case, the slice network list may be composed of slice networks whose slice network priority value is less than or equal to the second slice network priority value. Taking Table 11 as an example, assuming that the preset slice network priority value is 2, the slice network list may include slice networks whose slice network priority value is less than or equal to 2. In this case, the slice network list includes slice network 1 and slice network 2.

Further, the policy control network element may determine that the slice network list in the request information includes a service quality requirement of a service whose service priority value is less than a preset service priority value. For example, when network resources are sufficient or a specific value, the preset service priority value may be set to a first service priority value, and the first service priority value may be a maximum value of the service priority. In this case, quality of service requirements for all services can be requested. Taking Table 11 as an example, the first service priority value may be 3. Assuming that the preset service priority value is the first service priority value, the service quality requirements of all services can be requested. When the network resource is limited or is another specific value, the preset service priority value may be set as a second service priority value, and the second service priority value is smaller than the first service priority value. In this case, a service quality requirement of a service whose service priority value is less than or equal to the second service priority value may be requested. Taking Table 11 as an example, assuming that the preset service priority value is 2, you can request the service quality requirements for services with a service priority value less than or equal to 2. In this case, service 1 and service 2 and service 3 can be requested.

Taking Table 11 as an example, assuming that the preset slice network priority is 2 and the preset service priority is 2, the service quality requirements of the slice network list may include the service quality requirements of service 1 of the slice network 1, and the slice network. The quality of service requirements of service 2 of service 1, the service quality requirements of service 1 of slice network 2 and the service quality requirements of service 2 of slice network 2.

In some embodiments, the policy control network element may further send priority information of the slice network and / or service priority and / or quality of service requirements of the slice network to the data analysis network element, and the priority information of the slice network The priority of the service and / or the quality of service of the slice network may be included in the request information, or may not be included in the request information, and the time sequence with the request information is not limited.

In this step, the policy control network element sending the request information to the data analysis network element may specifically belong to a type of real-time request information or a type of subscription request information. If the request information is the real-time request information, after receiving the request information, the data analysis network element can immediately return the content requested by the policy control network element without performing the model training operation described in step 202, among which the model training operation Completed before receiving the request message. If the request information is the subscription request information, after receiving the request information, the data analysis network element needs to undergo model training before returning the content requested by the data analysis network element.

202. The data analysis network element sends network configuration information corresponding to the sliced network list to the policy control network element. Correspondingly, the policy controls the network element to receive network configuration information corresponding to the slice network list sent by the data analysis network element.

In some embodiments, step 201 may not be performed. That is, the data analysis network element may determine and execute the network configuration information corresponding to a sliced network list to the policy control network element by itself. For example, the data analysis netizen may determine the network configuration information corresponding to a slice network list according to the slice network priority information and / or service priority information, and send the network configuration information corresponding to the slice network list to the policy control network element. For the manner in which the data analysis network element determines the network configuration information corresponding to the slice network list according to the slice network priority information and / or service priority information, refer to the policy to control the network element according to the slice network priority information and / or service priority information. The method for determining the service quality requirements of the sliced network list need not be repeated here. To explain, the slice network priority information and / or service priority information may be obtained by the data analysis network element in advance from the policy control network element, service server or network management network element, or it may be configured in advance on the data analysis network element. There is no restriction here. In addition, in addition to the slice network priority information and / or service priority information, in order to obtain the network configuration information corresponding to the slice network list, the data analysis network element may also need to know the service quality corresponding to each slice network in all slice networks. Requirements, and the service quality requirements of each slice network can be obtained in advance by the data analysis network element from the policy control network element, service server, or network management network element, or it can be configured on the data analysis network element in advance, here No restrictions.

If step 201 is performed, the data analysis network element may determine the network configuration information corresponding to the slice network list that needs to be sent to the policy control network element according to the request information. The network configuration information corresponding to the slice network list sent to the policy control network element is the network configuration information corresponding to the slice network list obtained by the request information request.

The network configuration information is used to guide setting of each slice network in the slice network list and network elements related to the slice network.

Taking the network slice as an example, the network slice can be a complete end-to-end network including terminal equipment, access network, transmission network, core network, and service server. The network configuration information can be used to guide the setting of the network slice. Parameters of the access network, transmission network, core network, and / or service server; the network slice can also include only the core network but supplemented by terminal equipment, access network, transmission network, and service server, and the network configuration information can be It is used to guide the setting of the network slicing parameters and related access network, transmission network, and / or service server parameters. The parameters in the network configuration information include end-to-end parameters of network slices, parameters of a single network element device, or parameters on corresponding interfaces between the network element devices.

In some embodiments, the network configuration information corresponding to the sliced network list may include a set of network configuration information.

In other embodiments, the network configuration information corresponding to the sliced network list may include multiple sets of network configuration information.

Table 12 is a schematic table corresponding to multiple sets of network configuration information for a sliced network list.

Table 12

Table 12 is network configuration information corresponding to the slice network list corresponding to Table 2. Among them, Y1, Y2, and Y3 are three sets of network configuration information. Each group of network configuration information can be used to guide the setting of each slice network and related network elements in the three slice networks. For example, Y1 can be used to guide the network settings of slice network 1, slice network 2, and slice network 3. Y2 can be used to guide the network settings of slice network 1, slice network 2, and slice network 3. Y3 can be used to guide the slice network Network settings for network 1, slice network 2, and slice network 3.

In some embodiments, the policy control network element may also receive the applicable conditions corresponding to the network configuration information sent by the data analysis network element. The applicable conditions may include conditions such as when and where each group of network configuration information is applicable. This applicable condition can be used as part of the network configuration information or as additional information. In the case where the applicable condition is additional information, the applicable condition may be sent to the network management network element together with the network configuration information, and the applicable condition and the network configuration information may be sent to the network management network separately. yuan.

In other embodiments, the policy control network element may also receive the data analysis network element to send configuration effect information, and the configuration effect information is used to indicate multiple sets of network configuration information included in the network configuration information corresponding to the sliced network list. The quality of service effect that each group of network configuration information can achieve. For example, in a case where the service quality requirement of each slice network in the slice network list is the user satisfaction requirement of the services in the slice network, the configuration effect information is that each group of network configuration information can achieve for each slice network service. User satisfaction effect. The configuration effect information can be used as a part of the network configuration information or as an additional information. In a case where the configuration effect information is an additional information, the configuration effect information may be sent to the network management network element together with the network configuration information, and the configuration effect information and the network configuration information may also be sent to the network management information separately. Network management network element.

Specifically, if the service quality requirements of the slice network list include the service quality requirements of multiple slice networks, the service quality effect is a service quality effect that can be achieved by each slice network. If the service quality requirement corresponding to each slice network includes the service quality requirement of at least one service in each slice network, the service quality effect is a service quality effect that each service can achieve. If the service quality requirement corresponding to each slice network includes the service quality requirement corresponding to at least one user type in each slice network, the service quality effect is a service quality effect that can be achieved by each user type. If the service quality requirements corresponding to each slice network may include service quality requirements corresponding to at least one user type in one or more services in each slice network, the quality of service effect is The quality of service that the user type can achieve.

It is assumed that the service quality requirements of the slice list sent by the policy control network element to the data analysis network element are shown in Table 2. The network configuration information and configuration effect information sent by the data analysis network element can be shown in Table 13.

Table 13

As shown in Table 13, Y1, Y2, and Y3 represent three sets of network configuration information, respectively. For example, the service quality effect that Y1 can achieve is that the video service of slicing network 1 has a proportion of users with vMOS> 4 greater than 98%, the voice service of slicing network 1 has a proportion of users with MOS> 4 greater than 98%, and the video service of slicing network 2 has more than 98% The proportion of users with vMOS> 4 is greater than 92%, the proportion of users with MOS> 4 in the slicing network 2 is greater than 98%, and the proportion of users with vMOS> 4 in the video service for slicing network 3 is greater than 85%, and the voice for slicing network 3 is greater than 85% The proportion of users with MOS> 4 for services is greater than 90%. It can be seen that the three sets of network configuration information shown in Table 13 can meet the service quality requirements of slice network 1, slice network 2, and slice network 3 shown in Table 2.

In other embodiments, the policy control network element may also receive the use priority information of the network configuration information sent by the data analysis network element, and the use priority information indicates the priority of each group of network configuration information to be adopted or used. For example, Y1, Y2, and Y3 respectively represent three sets of network configuration information. The usage priority of Y1 is 1, the usage priority of Y2 is 2, and the usage priority of Y3 is 3. Has the lowest priority. The use priority information can be used as a part of the network configuration information or as an additional information. In the case where the usage priority information is additional information, the usage priority information may be sent to the network management network element together with the network configuration information, and the usage priority information and the network configuration information may also be sent to The network management network element.

The following describes how the data analysis network element determines network configuration information.

The data analysis network element obtains historical network configuration information corresponding to each slice network in the slice network list; the data analysis network element obtains historical service quality of each slice network in the slice network list; and the data analysis network element according to the The historical network configuration information corresponding to each slice network, the historical service quality of each slice network, and the service quality requirements of each slice network determine the network configuration information corresponding to each slice network; the data analysis network element is based on the The network configuration information corresponding to each slice network determines the network configuration information corresponding to the slice network list.

In some embodiments, the historical service quality data of each slice network includes the historical service quality of each service of each slice network. The historical service quality of each slice network includes the network identification information of the slice network and the number of users in the slice network. The network identification information of the slice network is used to uniquely identify the slice network and the number of users in the slice network. The number of registered users or online users in the slice. In addition, the historical service quality of each service may include at least one of the following information: service identification information of the service, network identification information of the slice network, number of services of the service, and users who meet the single user service quality requirements of the service Scale information. The service identification information of the service is used to uniquely identify the service; the network identification information of the network is used to uniquely identify the network and the network is the network on which the service runs; the number of services of the service refers to the number of The total number of services, for example, the number of voice services being executed is 10,000, and the number of video services being executed is 2,000. When it is assumed that one user can only perform one service of one service type at the same time, for example, one user can only perform one voice service at the same time, the number of services of one service is equivalent to the number of users who execute the service. In addition, if a service is subdivided into multiple single-user service quality value ranges, in this scenario, the number of services may be a requirement for the number of services corresponding to each single-user service quality value range. For example, the number of services corresponding to MOS = [3,4] is 5000, and the number of services corresponding to MOS = [4,5] is 5000. The proportion of users who meet the single-user service quality requirement of the service, that is, the user satisfaction of the service. In some embodiments, the proportion of users of the single-user service quality requirement of the service is the proportion of users corresponding to a single-user service quality requirement, such as The proportion of users with a voice service MOS greater than 3, and in other embodiments, the proportion of users with single-user service quality requirements for this service is the proportion of users with multiple single-user service quality requirements, such as users with voice service 3 <MOS <4 Ratio and 4 <MOS <5 user ratio.

In some embodiments, the historical service quality of each slice network may also be a service quality distinguished by the user type dimension, that is, the historical service quality of each slice network includes the history of at least one user type of each slice network. Quality of business. In this scenario, in addition to the above information, the historical service quality of each slice network also includes user type information. The user type information is used to distinguish the historical service quality corresponding to different user types, such as the historical service quality and Historical service quality for silver users.

In some embodiments, the historical service quality of each slice network may also be a historical service quality distinguished by a service type dimension, that is, the historical service quality of each slice network includes at least one service type of each slice network. Historical business quality. In this scenario, in addition to the above information, the historical service quality of each slice network also includes service type information or service identification information. The service type information or service identification information is used to distinguish historical service quality corresponding to different service types. For example, the historical service quality corresponding to the voice service and the historical service quality corresponding to the video service.

In some embodiments, the historical service quality of each slice network may also be a historical service quality distinguished by a spatial dimension, that is, the historical service quality of each slice network includes a history corresponding to at least one spatial information of each slice network. Quality of business. In this scenario, in addition to the above information, the historical service quality of each slice network also contains spatial information. For example, the historical service quality of the slice network may include the historical service quality of area 1 and the historical service quality of area 2. The specific form of the spatial information in the embodiments of the present application is not limited, as long as it can reflect the space. For example, the spatial information may be spatial information defined in the 3GPP communication network, such as serving cell A or registration area B. The space The information may also be spatial information defined in a non-3GPP communication network, for example, the spatial information is a specific geographic location range (for example, latitude and longitude or GPS spatial information).

In some embodiments, the historical service quality of each slice network may be a historical service quality distinguished by a time dimension, that is, the historical service quality of each slice network includes a historical service corresponding to at least one time information of each slice network. quality. In this scenario, in addition to the above information, the historical service quality of each slice network also contains time information. The specific form of the time information is not limited in the embodiment of the present application, as long as it can reflect the time. For example, the time information may be divided on an hourly basis, for example, the first time information is from 8 to 10 o'clock, and the second time information is from 10 to 12 o'clock. As another example, the time information may also be divided on a day basis, for example, the first time information is from the 1st to the 10th of each month, and the second time information is from the 11th to the 20th of each month. As another example, the time information may also be divided by the length of time the user is turned on. For example, the first time information is 0 to 4 hours after being turned on, and the second time information is 4 to 8 hours after being turned on. For example, the historical service quality may include historical service quality of time information 1 and historical service quality of time information 2.

In some embodiments, the historical service quality of each slice network may be combined according to any two or more of the service type dimension, user type dimension, spatial dimension, and time dimension, that is, the historical service Quality is the historical service quality corresponding to multiple dimensions of the slice network. In this scenario, in addition to the above information, the historical service quality of each slice network also includes one or more of service type information, user type information, spatial information, and time information.

First, for a service of a sliced network, introduce how the data analysis network element obtains the historical service quality of the service.

The data analysis network element can obtain the historical service quality of the service in the following three ways, as shown below.

First, the data analysis network element obtains the historical service quality of the service from the service server of the service.

During the operation of the service, the service server can obtain user-level service quality by its own measurement and calculation methods. The user-level service quality is used to indicate that at least one single user corresponds to the service quality of the service (for example, the service server can The measurement and calculation methods determine the quality of service for each single user executing the service), the service server can also obtain the single user service quality requirement information for the service, and the single user service quality requirement information refers to the service of a single user for the service Quality requirements (for example, the MOS score requirement for a single-user voice service is greater than 3). The service server determines the service quality data of the service corresponding to the historical time according to a large amount of single user service quality data and single user service quality requirement information corresponding to a historical time (time or time period), and the service server determines similarly multiple times The process can generate multiple service quality data corresponding to historical time, and multiple service quality data corresponding to historical time constitute the historical service quality of the service. Exemplarily, in one determination process, the service server judges that 80 of 100 users have a voice service MOS greater than 3, and the service server determines that the service quality data corresponding to a historical time is 80%; in another determination process, , The service server judges that 90 of 100 users have voice service MOS greater than 3, then the service server determines that the quality of service data corresponding to another historical time is 90%; similarly, after multiple determination processes, the service server can generate Historical business quality.

The service server sends the historical service quality of the service to the data analysis network element. Exemplarily, the service server may actively send historical service quality of the service to the data analysis network element; or, the data analysis network element sends request information for obtaining the historical service quality of the service to the server of the service, thereby When the service server receives the request information, it can send the historical service quality of the service to the data analysis network element.

The user-level quality of service data is used to indicate the quality of service of one or more single users corresponding to the service. Specifically, the service quality of each single user corresponding to the service includes, but is not limited to, the service quality of the service during a single service of the user, or the service quality of the service within a certain period of time of the user, or the The quality of the service at that point in time.

The service quality data of each single user includes at least one of the following information: user identification information, user's associated identification information, user's service quality evaluation data, and service description information. The identification information of the user is used to uniquely identify the user. For example, the identification information of the user may be one or more of the following: Internet protocol address (IP), subscription permanent identifier (SUPI), permanent device Identification (PEI), universal public subscription identifier (GPSI), international mobile subscriber identifier (IMSI), international mobile equipment identity (IMEI), IP 5-tuple and mobile station international integrated service digital network number (MSISDN), etc .; the user's associated identification information is used to correlate the user's quality of service data with the user's quality of service Flow-level network data corresponding to the data. For example, the user's associated identification information can be the IP address of the user terminal used by the user or the temporary identification allocated by the network for a single service flow of the user terminal. , The temporary identifier may be assigned by the PCF network element or the NWDAF network element or the NRF network element or other service network element to the service flow during the user's single service flow establishment process, and the assigned temporary identity is in the service flow establishment process The PCF network element, NWDAF network element, NRF network element, or other service network element is distributed to each network element corresponding to this service flow. The temporary identifier is used to associate network data of various flow levels corresponding to the service flow with the network flow. User service quality data; user service quality evaluation data refers to the data used to evaluate the user's service quality. For example, if the service is a voice service, the evaluation data can be the MOS score and smooth voice of a user's voice service. The service description information can include one or more of the following information: the service identifier to which the service flow belongs, IP filtering information, media bandwidth requirements, traffic routing information, jitter buffer requirements, media encoding type requirements, and media encoding type Required encoding rate requirements, TCP congestion window requirements, TCP receive window requirements, buffer requirements, and at least one data Type value requirements.

Optionally, the service server obtaining the service quality data of each single user may include data after normalization processing, so as to ensure the security of user information. The normalization processing here refers to the operation of mapping the physical value of the parameter to a fixed value space, for example, using the maximum and minimum normalization method, Z-Score normalization method, etc. to map the physical value of each feature. Into a fixed numeric space.

In addition, the single-user service quality requirement information of the service is used to indicate the single-user service quality requirement of the service, that is, the tenant or the service server's requirements for the service quality of each single user of the service can be transferred from the tenant to the service server. Provided, the single user service quality requirement information of the service may be included in the SLA. Of course, the single user service quality requirement information of the service can also be configured in the service server. For example, the service is a voice service, and the single-user service quality requirement information of the service provided by the tenant is that each user's voice service MOS score is greater than or equal to 3 points.

It should be noted that the method or algorithm used by the service server to determine the historical service quality of the service and the type of historical service quality generated can be customized according to the user-level service quality data and the single user service quality requirement information of the service. This embodiment of the present application does not specifically limit this.

Further, when the service server obtains user-level quality of service data, the service quality of multiple single users can be obtained according to the time dimension to form user-level quality of service data, or the service quality of multiple single users can be obtained according to the spatial dimension to form user levels. Quality of service data, or obtain the quality of service of multiple single users according to the time and space dimensions to form user-level quality of service data. When the service server of the service obtains user-level service quality data according to the time dimension, it can obtain service quality data of each user of the service at a certain point in time (for example, 8 o'clock in the morning), or obtain a certain period of time (For example, 8 am to 6 pm) quality of service data for each user of the service. When the service server of the service obtains user-level service quality according to the spatial dimension, it can obtain service quality data of each user in the entire slice network running the service, or obtain a certain area (such as a certain latitude and longitude range or registration area ( Registration (area, RA) or tracking area (TA) or cell list (cell list) quality of service data of each user, or to obtain each location at a certain location (for example, a certain cell or a certain latitude and longitude point) User quality of service data. When the service server of the service obtains user-level service quality data according to the time dimension and the space dimension, it can obtain the service quality data of each user of the service at a certain point in time or within a certain period of time, for example, The data analysis network element can obtain service quality data of each user of the service cell A at 8 am to form a user-level service quality, or obtain each service of the service cell A from 8 am to 6 pm The user's quality of service data forms user-level quality of service data and the like. To explain, when the service server obtains user-level service quality data according to the above-mentioned time dimension, space dimension, time or space dimension, then the service server obtains each historical service quality data of the service according to the user-level service quality data. It also has the characteristics of time dimension, space dimension, time or space dimension. For example, the data analysis network element can obtain the service quality data of each user of the service in the historical serving cell A from 8 am to 6 pm to form the historical service quality data of the service. The obtained historical service quality data of the service corresponds to the historical service quality of all or multiple users of the service cell A from 8 am to 6 pm.

The second type is that the data analysis network element obtains the user-level historical service quality data of the service from the service server, and obtains the historical service quality of the service according to the user-level historical service quality data.

The user-level historical service quality data refers to the historical service quality data obtained by a single user performing the service. The user-level historical service quality data includes historical service quality data of one or more single users. The quality of service data of each single user is as described in the first method, and is not repeated here.

During the operation of the service, the service server can directly obtain user-level quality of service data. The service server sends user-level service quality data (that is, user-level historical service quality data) in the past period to the data analysis network element. Exemplarily, the service server may actively send historical user quality data of the user level to the data analysis network element; or, the data analysis network element sends request information to the service server for obtaining historical service quality data of the user level, Therefore, when the request information is received by the service server, historical service quality data at the user level can be sent to the data analysis network element.

In addition, the data analysis network element obtains the historical service quality of the service according to the historical service quality data of the user level, including: the data analysis network element obtains the single user service quality requirement information of the service from the service server or the policy control network element, and the single user Service quality requirement information refers to the service quality requirements for a single user to perform this service. For example, the voice service single user service quality requirement is MOS greater than 3 points; based on a large number of user-level historical service quality data and single user service quality requirement information, determine Historical business quality of the business. For example, the data analysis network element judges whether the quality of service data of each user at a historical moment meets the user-level quality of service requirements, thereby determining the proportion of users who meet the single-user quality of service requirements of the service, and uses this proportion as the historical moment. Historical business quality.

It should be noted that the user-level historical service quality data sent by the service server to the data analysis network element may be multiple user-level data obtained by the service server in a time dimension, a space dimension, or a combination of the time dimension and the space dimension. Historical business quality data.

In addition, the data analysis network element can customize the method or algorithm used to determine the historical service quality of the service and the type of historical service quality generated based on the user-level historical service quality data and single-user service quality requirement information. The application embodiment does not specifically limit this.

Third, the data analysis network element obtains user-level or flow-level network data of the service, and obtains historical service quality of the service according to the user-level or flow-level network data.

The user-level or flow-level network data refers to network flow data corresponding to a single service process for each user. Here, the network flow in the 5G network may specifically be a quality of service (QoS) flow. The network flow data may specifically include quality of service (QoS) parameters provided by the network device for the user's single service process, such as Guaranteed Flow Bit Rate (GFBR), Maximum Flow Bit Rate (Maximum Flow Bit Rate (MFBR), Uplink and Downlink Maximum Packet Loss Rate, UL or DL Max PLR, Packet Delay Budget (PDB), Packet Error Rate (Paper Error Rate, PER) ), Average window size (Average window size), Maximum data burst number (Maximum Data Burst Volume).

Specifically, this method can be divided into three execution phases:

Phase 1: The data analysis network element obtains the single-user service quality model of the service, that is, the user-level service quality model. The model refers to the change in user-level service quality of the service with user-level or stream-level network data. relationship.

For example, the data analysis network element can obtain the single-user service quality model of the service in the following two steps:

A. Data analysis The network element obtains the training data of the service. The training data corresponds to the above-mentioned user-level service quality data and user-level or stream-level network data.

The data analysis network element is first from the service server (such as AF), the access network element (such as RAN), the user plane function network element (such as UPF), the terminal device (such as UE), and the mobility management function network element (such as AMF) , Session management function network element (such as SMF), policy control function network element (such as PCF) and other network elements collect data separately, and then through the service identity, service flow identity, terminal identity, session identity where the service flow is located, each network element The associated identification information, time, and other information on each link the data of each network element to obtain complete training data. The training data includes:

(1) User-level quality of service data from the service server.

The user-level quality of service data includes at least one single user's quality of service data. The content of the single user's quality of service data can be specifically referred to in the first method, and will not be repeated here.

(2) Other time-varying parameter data that affects user-level quality of service data, that is, user-level or flow-level network data. include:

i. TCP congestion window data, TCP reception window data, jitter buffer data, media encoding type and encoding rate data, buffer data, at least one data type data from the AF network element;

ii. RAN network element stream bit rate data, packet loss rate data, delay data, wireless channel quality data, data of at least one data type;

iii. Stream bit rate data, packet loss rate data, delay data, and data of at least one data type from the UPF network element;

iv. Stream bit rate data, packet loss rate data, delay data, at least one data type data, TCP congestion window data, TCP reception window data, jitter buffer data, media encoding type and encoding rate data, buffer data from the UE Data of at least one data type, CPU usage, memory usage;

v. Wait.

It should be noted that the user-level or flow-level network data may also include network data after being subjected to normalization processing, which is not specifically limited in this embodiment of the present application.

B. Exemplarily, the data analysis network element obtains a user-level service quality data and user-level or stream-level network data relationship model based on the Linear Regression method, that is, a single-user business experience model, as follows

h (x) = w ₀ x ₀ + w ₁ x ₁ + w ₂ x ₂ + w ₃ x ₃ + ... + w _D x _D , (Equation 1.1)

In formula (1.1), h (x) is the user-level service quality of a certain service, for example, the MOS value of a single user's voice service; X = (x ₁ , x ₂ , x ₃ , ..., x _D ) Is a feature vector, for example, x ₁ represents a delay, x ₂ represents a packet loss rate, x ₃ represents a stream bit rate, ..., x _{D represents a} TCP congestion window, and x ₀ is a constant 1; W = (w ₁ , w ₂ , w ₃ ,..., w _D ) are parameter vectors, also called weight vectors, and w _i represents the weight of the impact of the i-th parameter on the quality of service at the user level.

The above linear regression is only an exemplary data analysis algorithm. The data analysis network element can obtain a single user service experience model based on other algorithms, and the present invention does not specifically limit it.

Phase 2: Data analysis The network element obtains user-level service quality data based on the existing single-user service quality model and user-level or flow-level network data.

To explain, the difference between the user-level or stream-level network data described in phase two and the user-level or stream-level network data described in phase one is that in time, the former occurs after the latter, that is, described in phase one Of user-level or stream-level network data is historical user-level or stream-level network data described in phase two, and it can be inferred that the user-level service corresponding to user-level or stream-level network data described in phase one The quality data is also historical data of user-level service quality data corresponding to the user-level or flow-level network data in phase two. In addition, the difference between the user-level quality of service data in phases 1 and 2 is that the former is obtained from the data analysis network element from the service server, and the latter is obtained from the data analysis network element itself.

Specifically, if the data analysis network element has learned that h (x) = model in the above formula (1.1), then according to the independent variable X = (x ₁ , x ₂ , x ₃ , ..., x _D ) at a subsequent time point (That is, the network data of the stream level corresponding to a subsequent point in time). The data analysis network element can calculate the specific value of h (x) at the subsequent point in time. For example, h (x) is MOS = 3 for the voice service. The value of h (x) is the derived quality of service for a single user. A large number of single-user service quality data obtained by using this process method for many times constitute user-level service quality data.

In the method described in this stage, after the data analysis network element obtains a stable single-user service quality model through the method of phase 1, the data analysis network element can use the user-level or flow-level network data to infer the corresponding user-level service quality. data.

Phase 3: Data analysis The network element obtains the historical service quality of the service based on the historical user-level service quality data obtained in phase 2.

Wherein, at this stage of the data analysis, how the network element obtains the historical service quality of the service according to the historical user-level service quality data. For details, please refer to the second method described above, which will not be repeated here. The only difference is that the user-level quality of service data sources are different. In the second method, the user-level quality of service data originates from the service server, and here comes from the data analysis network element itself generated in phase two.

Fourth, the data analysis network element obtains the historical service quality of the service from other network elements with data analysis functions.

For example, when the data analysis network element in this embodiment is a network element with a data analysis function (such as MDAS) in the network management system, the data analysis function network element may be obtained from a data analysis function network element (such as MDAS) on the control plane of the core network. NWDAF) to obtain the historical service quality of the service.

Before sending the historical service quality of the service to the data analysis network element, the other network element with data analysis function can use any of the methods described in the first, second, and third to obtain the historical service quality of the service. Here, No longer.

In some embodiments, the other network element having a data analysis function may actively send historical service quality data of the service to the data analysis network element;

In other embodiments, the data analysis network element sends request information for obtaining historical service quality data of the service to the other network element with the data analysis function, so that the data received by the other network element with the data analysis function When the information is requested, historical service quality data of the service may be sent to a data analysis network element.

Wherein, optionally, the request information is generated by the data analysis network element according to the service quality requirements of the sliced network list in step 201. For example, if MDAS receives the service quality requirement information of the slice list as shown in Table 2 via step 201, MDAS requests the following information from NWDAF: historical service quality data corresponding to the voice service of slice network 1, and video service of slice network 1. Corresponding historical service quality data, historical service quality data corresponding to the voice service of the slice network 2, historical service quality data corresponding to the video service of the slice network 2, historical service quality data corresponding to the voice service of the slice network 3, and Historical service quality data corresponding to video services.

Or, optionally, the request information is generated by the data analysis network element according to the priority information and / or service priority information of the slice network sent in 201. For example, if MDAS receives priority information and service priority information of the slice network as shown in Table 11 in step 201, the MDAS may decide to request the NWDAF to request the slice network priority less than 2 and the service priority less than 1. Historical service quality data, that is, MDAS requests the following information from NWDAF: historical service quality data corresponding to service 1 of slice network 1, and historical service quality data corresponding to service 1 of slice network 2. Optionally, the historical service quality of the slice network requested by the data analysis network element in the request information corresponds to the network configuration information of the slice network list sent by the data analysis network element to the policy control network element in step 202.

To explain, if the data analysis network element obtains the spatial information in the historical service quality data and the spatial information in the flow-level historical network data, there may be inconsistencies. For example, the former is GPS spatial information and the latter is cell identification information. Meta can use the user's associated identification information contained in historical service quality data and flow-level historical network data to establish a mapping relationship between two different types of spatial information. Thereafter, the data analysis network element can train a service experience model based on one of the spatial information.

The previous article took a service in a slice network as an example, and introduced how the data analysis network element obtains historical service quality data of each slice network in the slice network list. On this basis, the data analysis network element obtains the historical network configuration information of each slice network corresponding to the historical service quality data of each slice network in the slice network list. For example, for one of the slice networks, the data analysis network element can use the time information to correlate the service quality of the slice network at a historical point in time (for example, at 8 o'clock in the morning, the voice service user satisfaction of slice network 1 is 80% and video service (The satisfaction rate is 90%) corresponding to the historical network configuration information of the slice network. Here, the historical network configuration information of the slice network can be obtained from the network management network element or other network function network elements. The historical network configuration information of the sliced network includes the historical measurement data or historical performance data on the end to end of the network slice, a single network element device, or a corresponding interface between the network element devices. For details, see the explanation of the network configuration information in step 202. For another example, for one of the slice networks, the data analysis network element can use spatial information to correlate the service quality of the slice network in a certain space (such as the user satisfaction of the voice service of the slice network 1 in the cell 1 and the satisfaction of the video service 80%). 90%) of the historical network configuration information of the slice network. Of course, besides this, for one of the slice networks, the data analysis network element can use the spatial information and time information to correlate the service quality of the slice network at a certain time in a certain space (for example, 8 o'clock in the morning, cell 1 slice network 1 voice service). (User satisfaction is 80% and video service satisfaction is 90%) corresponding to the historical network configuration information of the slice network. Here, the historical network configuration information of the slice network can be obtained from the network management network element or other network function network elements. The historical network configuration information of the sliced network includes the historical measurement data or historical performance data on the end to end of the network slice, a single network element device, or a corresponding interface between the network element devices. For details, see the explanation of the network configuration information in step 202.

The following describes how a data analysis network element determines the network configuration corresponding to a service in a slice network for a service in a slice network:

The data analysis network element may use the historical service quality data of the service in the slice network and the historical network configuration information data of the slice network to train a training model for the service of the slice network, where the training model refers to the service The quality of service should be a function of the network configuration information of the slice network.

Exemplarily, the training model obtained by the data analysis network element based on the linear regression method is as follows:

g (y) = w ₀ y ₀ + w ₁ y ₁ + w ₂ y ₂ + w ₃ y ₃ + ... + w _D y _D , (Equation 1.2)

g (y) indicates the service quality of the service, for example, the user satisfaction of the service, that is, the proportion of users who meet the single user service quality requirements of the service. In formula 1.2, the Y = (y ₁ , y ₂ , y ₃ , ..., y _D ) feature vector refers to the network configuration information that affects the service quality of the service, where the network configuration information refers to the slice network and the slice network. Network parameter settings of related network elements. These network configuration information may be collected by the data analysis network element from the network management network element or directly from the related network elements of the slice network. Exemplarily, y ₁ represents the uplink packet loss rate of the next generation radio access network (NG RAN), y ₂ represents the average delay of the air interface, and y ₃ represents the uplink / downlink usage rate of the N6 interface. . W = (w ₁ , w ₂ , w ₃ ,..., W _D ) is a parameter vector, also called a weight vector identifier, and w _i identifies the i-th parameter y _i in the network configuration information, which affects the service quality of the service The size of the weights.

To explain, the type of network configuration information in the feature vector Y = (y ₁ , y ₂ , y ₃ , ..., y _D ) obtained through model training can be included in the type of historical network configuration information in the slice, that is, history A subset of the type set of network configuration information. For example, a data analysis network element obtains 100 types of network configuration information for a sliced network from a network management network element, but after model training, it learns that 50 types of network configuration information affects the quality of service of the service for the sliced network. The configuration information is the feature vector,

After obtaining the above training model, according to the model and the service quality requirements of the service in the slice network, the data analysis network element obtains network configuration information that meets the requirement, where the network configuration information refers to if the network management network element If the configuration information is used to set network settings for the slice network, the service of the slice network can meet the service quality requirements corresponding to the service.

For example, assuming that the service quality requirement of the service on the slice network is that the user satisfaction is greater than 95%, that is, g (y)> 95% is required, according to the above formula 1.2, the data analysis network element can obtain g (y)> 95% corresponding The specific values of the Y = (y ₁ , y ₂ , y ₃ ,..., Y _D ) feature vector.

The value of the feature vector corresponding to the service quality requirement according to the training model is a multiple objective decision making (MCDM) problem. The data analysis network element can obtain the feature vector based on the existing MCDM method. value. Generally speaking, multiple sets of feature vectors that meet service quality requirements can be obtained, and multiple sets of corresponding network configuration information can be obtained.

The above is for a service in a slice network, and how the data analysis network element determines the network configuration corresponding to the service in the slice network. For multiple services in a slice network, the data analysis network element can obtain a training model corresponding to multiple services according to similar methods, such as g _i (y):

g _i (y) = w _i0 y ₀ + w _i1 y ₁ + w _i2 y ₂ + w _i3 y ₃ + ... + w _iD y _D (Equation 1.3)

Where formula 1.3 represents the training model corresponding to the ith service in the slice network, and Y = (y ₁ , y ₂ , y ₃ , ..., y _D ) represents the network configuration information corresponding to the slice network, which indicates that there is y _1- The y _D parameters affect the service quality of each service in the slice network. According to the g _i (y) model corresponding to the above service i and the requirements of g _i (y), the data analysis network element can obtain a solution that meets the requirements Y = (y ₁ , y ₂ , y ₃ , ..., y _D ) , And the solution may have multiple sets of different values.

For a scenario where there are multiple slice networks in a slice list and each slice network has multiple services, the method for the data analysis network element to obtain the corresponding network configuration information of the slice list is similar to the above. The following uses the service quality requirements of the sliced network list shown in Table 2 as an example to describe this method in detail:

Exemplarily, using the similar linear regression method described above, the data analysis network element obtains the corresponding multiple service training models for the multiple services of the sliced network list listed in Table 2 as shown in the following table:

Table 14

Where: (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h ) are feature vectors that affect the video service of slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _i ) are feature vectors that affect the voice service of slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j ) are feature vectors that affect the video service of slice network 2;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _k ) are feature vectors that affect the voice service of slice network 2;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _p ) are feature vectors that affect the video service of slice network 3;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _q ) are feature vectors that affect the voice service of slice network 3.

The feature vectors of the above slice networks ₁ , ₂ , and ₃ can form a total feature vector Y = (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h , ..., y _i , ..., y _j , ..., y _k , ..., y _q ).

Corresponding to the service quality requirements of the slice network list listed in Table 2, the data analysis network element uses multiple models in Table 14 above to obtain multiple sets of solutions that meet the service quality requirements as shown in the following table, that is, services are obtained Multiple sets of network configuration information corresponding to quality requirements:

Table 15

In Table 15:

Y1 = (y ₁₀ , y ₁₁ , y ₁₂ , y ₁₃ , ..., y _1h , ..., y _1i , ..., y _1j , ..., y _1k , ..., y _1q );

Y2 = (y ₂₀ , y ₂₁ , y ₂₂ , y ₂₃ , ..., y _2h , ..., y _2i , ..., y _2j , ..., y _2k , ..., y _2q );

_{_{Y3 = (y 30, y 31}} , y 32, y 33, ..., y 3h, ..., y 3i, ..., y 3j, ..., y 3k, ..., y 3q).

Y1, Y2, and Y3 are the three specific values of the total feature vector, that is, three sets of solutions that meet the six service quality requirements listed in Table 2 above, that is, the network configuration parameters of the slice network 1, 2, and 3. If configured according to the values of the vectors listed in Y1, the six service quality requirements in the above slice list combination can be satisfied at the same time, and the meanings of Y2 and Y3 are similar. To illustrate, the network configuration parameters of slice network 1 involved here are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h , ..., y _i ), and the network configuration parameters of slice network 2 are ( y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j , ..., y _k ), the network configuration parameters of slice network 3 are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _p , ... , Y _q ), and Y1 is a set of values for all network configuration parameters included in the slice networks 1, 2, and 3, and Y2 and Y3 have similar meanings. After receiving the Y1, the network management device can determine that the network configuration parameters of the slice network 1 involved are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h , ..., y _i ), and the slice network The network configuration parameters of 2 are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j , ..., y _k ), and the network configuration parameters of slice network 3 are (y ₀ , y ₁ , y ₂ , y _3). , ..., y _p , ..., y _q ).

To explain, in this embodiment, it is assumed that slice networks 1, 2, and 3 share certain network resources, such as access network resources, AMF resources, and the like, and different services in each slice network are affected by the configuration of these common resource parameters. Therefore, the phenomenon that there are the same elements y ₀ , y ₁ , y ₂ , and y ₃ in the above several feature vectors has appeared. Of course, this application does not limit whether resources are shared between different slice networks, or whether different network resources are shared between different services in the same slice network. When different slice networks do not share network resources, common elements will not appear in the feature vectors of services in different slices. When different services in the same slice network do not share network resources, feature vectors of different services will not. Common elements appear.

For a scenario where there are multiple slice networks in a slice list and each slice network has multiple user types and multiple services, the method for the data analysis network element to obtain the corresponding network configuration information of the slice list is similar to the above. The following uses the service quality requirements of the sliced network list shown in Table 5 as an example to describe this method in detail:

Exemplarily, using the similar linear regression method described above, the data analysis network element obtains the corresponding multiple service training models for the multiple services of the slice network list listed in Table 5 as shown in the following table:

Table 16

among them:

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h ) are feature vectors that affect the video service of the gold user of the slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _i ) are feature vectors that affect the video service of the silver user of the slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j ) are feature vectors that affect the voice service of the gold medal user of slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _k ) are feature vectors that affect the voice service of the silver medal user of slice network 1, and so on.

The feature vectors of the above slice networks ₁ , ₂ , and ₃ can form a total feature vector Y = (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h , ..., y _i , ..., y _j , ..., _{_{y k, ..., y p,}} ..., y q, ..., y r, ..., y s, ..., y t, ..., y u, ..., y v, ... y w).

Corresponding to the service quality requirements of the sliced network list listed in Table 5, the data analysis network element uses multiple models in Table 16 above to obtain multiple sets of solutions that meet the service quality requirements as shown in the following table, that is, services are obtained Multiple sets of network configuration information corresponding to quality requirements:

Table 17

In Table 17:

Y4 = (y ₄₀ , y ₄₁ , y ₄₂ , y ₄₃ , ..., y _4h , ..., y _4i , ..., y _4j , ..., y _4k , ..., y _4p , ..., y _4q , ..., y _4r , ..., y _4s , ..., y _4t , ..., y _4u , ..., y _4v , ... y _4w )

Y5 = (y ₅₀ , y ₅₁ , y ₅₂ , y ₅₃ , ..., y _5h , ..., y _5i , ..., y _5j , ..., y _5k , ..., y _5p , ..., y _5q , ..., y _5r , ..., y _5s , ..., y _5t , ..., y _5u , ..., y _5v , ... y _5w ).

Y4 and Y5 are two specific values of the total feature vector, that is, two sets of solutions that meet the service quality requirements of the two user types listed in Table 5 above, that is, the network configuration parameters of the slice network 1, 2, and 3. If configured according to the values of the vectors listed in Y4, the 12 service quality requirements in the above slice list combination can be satisfied at the same time, and the meaning of Y5 is similar. To illustrate, (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h ) is a feature vector that affects the video service of the gold user of the slice network 1; (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _i ) is the feature vector that affects the silver user video service of slice network 1; (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j ) is the feature vector that affects the gold user voice service of slice network 1; (y _{_{_{0, y 1, y 2,}}} y 3, ..., y k) is sliced 1 Effect silver voice service network user feature vector, then sliced network 1 network configuration parameter relates to a combination of the four feature vectors, thereby analogy. Y4 is a set of values for all network configuration parameters included in slice networks 1, 2, and 3. Y5 has similar meaning. After receiving the Y4, the network management device can determine that the network configuration of the slice network 1 involved is (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _i ) + (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _h ) + (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _j ) + (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _k ), and so on . .

One point of explanation: The above linear regression algorithm is only a specific example algorithm of the data analysis network element training related model. The data analysis network element can also train the above model and seek network configuration information based on other algorithms, which is not limited in this patent.

In addition, the above data analysis network element trains a corresponding model for each user type corresponding to a service in a slice, for example, a gold model user for the voice service of slice network 1 trains a model, and at the same time, the voice of slice network 1 Silver users of the business also trained a model. In other algorithm designs, the data analysis network element can aggregate the two user types to generate a comprehensive model. The comprehensive model expresses the relationship between the aggregated service satisfaction of all user types and the network configuration information of the slice network. The relationship between the changes in the aggregated service of all user types may be an index that expresses the service quality of the service as defined by the data analysis network element itself or obtained from the policy control network element. See the following schematic method for details:

Table 18

In Table 18, the objective function f _i (y) is the aggregated service satisfaction of all user types corresponding to the slice network i. For example, the data analysis network element may use the weighted service satisfaction of each type of user as the aggregated service satisfaction. Specifically, the weight of each type of user satisfaction is the proportion of the type of users to the total number of users. Assuming that the above number of gold users accounts for 30% of the total users and silver users account for 70% of the total users, the aggregate satisfaction It can be defined as 30% × gold user business satisfaction + 70% × silver user business satisfaction. The Y feature vector on the left is a feature vector that affects the value of the objective function, and its meaning is similar to the previous one.

Before the process of training the model described above, the data analysis network element first obtains the historical business satisfaction data of the gold and silver users from the historical service quality data of the slice network, and then calculates the historical aggregation of the slice network according to the definition of the aggregate satisfaction Satisfaction data, and the historical aggregated satisfaction data will be used as the above-mentioned objective function value f _i (y) for the model training process. The final data analysis network element can obtain the function model illustrated in Table 18 above.

among them:

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _a ) are feature vectors that affect the video service of slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _b ) are feature vectors that affect the voice service of slice network 1;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _c ) are feature vectors that affect the video service of slice network 2;

(y ₀ , y ₁ , y ₂ , y ₃ , ..., y _d ) are feature vectors that affect the voice service of slice network 2, and so on.

The feature vectors of the above slice networks ₁ , ₂ , and ₃ can form a total feature vector Y = (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _a , ..., y _b , ..., y _c , ..., y _d , ..., y _e , ..., y _f ).

After obtaining the service quality requirements corresponding to multiple user types of the service for a slice network from the policy control network element, the data analysis network element can also calculate the aggregate service quality requirements for the service according to similar definitions. The total number of users is 30%, and the number of silver users accounts for 70% of the total number of users. Assume that according to the requirements shown in Table 5, the service satisfaction requirement for the gold users of the voice service of the slice network 1 is MOS> 3, and the proportion of users is> 95%. The satisfaction rate of silver users of the voice service of network 1 is MOS> 3, and the proportion of users is> 90%. The data analysis network element obtains the aggregate service quality requirement of 30% × 95 + 70% × 90 = 91.5, that is, MOS> 3. The proportion of users is greater than 91.5%.

Based on the f _i (y) models that have been obtained and the corresponding aggregate service quality requirements, the data analysis network can obtain multiple sets of solutions that meet the aggregate service quality requirements as shown below:

Table 19

In Table 19:

_{_{Y6 = (y 60, y 61}} , y 62, y 63, ..., y 6a, ..., y 6b, ..., y 6c, ..., y 6d, ..., y 6e ..., y 6f);

Y7 = (y ₇₀ , y ₇₁ , y ₇₂ , y ₇₃ , ..., y _7a , ..., y _7b , ..., y _7c , ..., y _7d , ..., y _7e ..., y _7f )

Y6 and Y7 are two specific values of the total feature vector, that is, two sets of solutions that meet the aggregate service quality requirements of each service of each slice network, that is, the network configuration parameters of slice networks 1, 2, and 3. To illustrate, the network configuration parameters of slice network 1 involved here are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _a , ..., y _b ), and the network configuration parameters of slice network 2 are ( y ₀ , y ₁ , y ₂ , y ₃ , ..., y _c , ..., y _d ), and the network configuration parameters of slice network 3 are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _e , ... , Y _f ), and Y6 is a set of values for all network configuration parameters included in the slice networks 1, 2, and 3, and the meaning of Y7 is similar. After receiving the Y6, the network management device can determine that the network configuration parameters of the slice network 1 involved are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _a , ..., y _b ), and the slice network The network configuration parameters of 2 are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _c , ..., y _d ), and the network configuration parameters of slice network 3 are (y ₀ , y ₁ , y ₂ , y ₃ , ..., y _e , ..., y _f ).

The method shown in Table 18 illustrates the process in which a data analysis network element trains a comprehensive model of a slice network for a scenario where a slice network corresponds to the service quality requirements of multiple user types.

In other embodiments, for the scenario of multiple service quality requirements corresponding to one service in a slice network, for example, as shown in Table 3, the data analysis network element may also train a comprehensive model corresponding to one service of a slice network. Alternatively, the implementation method may be similar to the method referred to in Table 18.

In other embodiments, when a slice network contains service quality requirements of different service types, such as the example scenario in Table 2, the data analysis network element can also train a comprehensive model corresponding to the slice network. Optionally, implement The method may be similar to the method referred to in Table 18.

In other embodiments, when a slice network contains service quality requirements corresponding to different spatial information, such as the example scenario in Table 6, the data analysis network element may also train a comprehensive model corresponding to the slice network. Optionally, implement The method may be similar to the method referred to in Table 18.

In other embodiments, when service quality requirements of different time information are contained in a slice network, such as the example scenario in Table 7, the data analysis network element may also train a comprehensive model corresponding to the slice network. Optionally, implement The method may be similar to the method referred to in Table 18.

In other embodiments, when a slice network contains service quality requirements corresponding to any one or more dimensions of different user types, service types, time information, and spatial information, the data analysis network element may also train a slice The comprehensive model corresponding to the network, optionally, the implementation method may be similar to the method mentioned in Table 18.

In some embodiments, the policy control network element may further send slice network priority information and / or service priority information and / or user type priority information to the data analysis network element.

In some embodiments, the policy control network element may further send corresponding service quality requirements of all slice networks to the data analysis network element.

The slice network priority information and / or service priority information and / or user type priority information, and the corresponding service quality requirement information of all slice networks may or may not be included in the request information of step 201, and is related to the request There is no chronological order in which messages are sent.

The data analysis network element determines that when the service quality requirements of the sliced network list are met, the quality of service requirements of the sliced network / service / user type of the sliced network list are also as far as possible satisfied according to the priority.

For example, if the data analysis network element reaches Y1, Y2, and Y3 according to the above method, but Y1 meets the service quality requirements corresponding to the medium and high priority slice network in the slice network list, then the data analysis network element prioritizes the use of Y1. Set higher. The policy controls the control network element and the network management network element to preferentially use Y1 as the network configuration information for configuring the slice network.

The specific content of the network configuration information will be introduced below.

Each group of the network configuration information in the one or more groups of network configuration information may include at least one network configuration parameter.

If each group of network configuration information includes only one network configuration parameter, the network configuration parameter may be one of a performance parameter or a specific setting parameter.

If the set of network configuration information includes multiple network configuration parameters, each of the multiple network configuration parameters may be one of a performance parameter or a specific setting parameter.

Performance parameters refer to the requirements for a certain performance index in the network. The network management network element performs internal processing accordingly to meet the requirements of the performance index. For example, the end-to-end delay of a network slice is a performance parameter. The network management network element performs internal resource settings according to the delay requirement to meet the delay requirement. For example, the key performance indicator (KPI) of network slicing defined on the current standard is a specific example of a performance parameter

The specific setting parameter refers to a parameter that the network management network element can directly perform the network setting accordingly. For example, the number of access network buffer resources and antenna tilt are two setting parameters. The network management network element directly sets the number of access network buffer resources and the antenna tilt angle accordingly.

Examples of specific network configuration parameters included in the network configuration information are listed in the following table. The network configuration information includes but is not limited to the network configuration parameters listed in the following table.

Table 20

In some embodiments, the method shown in FIG. 2 may further include step 203.

203. The policy control network element may further send the received network configuration information corresponding to the sliced network list to the network management network element. Correspondingly, the network management network element receives network configuration information corresponding to the slice network list sent by the policy control network element.

As shown above, the network configuration information corresponding to the sliced network list may include one or more groups of network configuration information.

In some embodiments, the policy control network element may send all the network configuration information included in the received network configuration information corresponding to the sliced network list to the network management network element. In other words, if the network configuration information corresponding to the sliced network list includes multiple sets of network configuration information, the policy control network element may send the multiple sets of network configuration information to the network management network element.

In some embodiments, the policy control network element may send a set of network configuration information included in the received network configuration information corresponding to the sliced network list to the network management network element. For ease of description, a set of network configuration information in the network configuration information corresponding to the slice network list sent to the network management network element is hereinafter referred to as first target network configuration information.

In some embodiments, the policy control network element may also receive the applicable conditions corresponding to the network configuration information sent by the data analysis network element. The applicable conditions may include conditions such as when and where each group of network configuration information is applicable. The applicable condition may be sent to the network management network element together with the network configuration information. This applicable condition can be used as part of the network configuration information or as additional information.

It can be understood that if the network configuration information corresponding to the slice network list includes only a group of network configuration information, the first target network configuration information is a group of network configuration information included in the network configuration information corresponding to the slice network list.

If the network configuration information corresponding to the sliced network list includes multiple sets of network configuration information, the first target network configuration information may be determined according to various methods.

In some embodiments, the policy control network element may determine that any one of the plurality of sets of network configuration information is the first target network configuration information.

In some embodiments, if the policy control network element receives the applicable conditions of the network configuration information sent by the data analysis network element, the policy control network element may determine the multiple sets of network configuration information according to the applicable conditions of the network configuration information. One of them configures information for the first target network. The first target network configuration information may be network configuration information applicable to the current time or location.

In other embodiments, when the policy control network element receives the data analysis network element and sends the configuration effect information, the policy control network element may determine that one of the multiple sets of network configuration information is the first target according to the configuration effect information. Network configuration information. The first target network configuration information may be a set of network configuration information capable of achieving the best service quality effect. The ability to achieve the best service quality effect can mean that all slice networks in the slice network list can achieve the best service quality effect, or it can mean that the specified slice network or the specified service in the slice network list can achieve the best service quality. effect. The designated slice network may be determined according to the slice network priority. That is, the policy control network element may determine the first target network configuration information according to the slice network priority information. For example, the slice network with the highest priority is the specified slice network. The designated service may be determined according to a service priority. That is, the policy control network element may determine the first target network configuration information according to the service network priority information. For example, the service with the highest service priority is the specified service.

Taking Table 13 as an example, assuming that the first target network configuration information is such that the slicing network with the highest priority of the slicing network can achieve the best quality of service effect, and assuming that the slicing network 1 has the highest priority, the first target network configuration information Can be Y1.

Taking Table 13 as an example, assuming that the first target network configuration information is to enable the service with the highest service priority to achieve the best service quality effect, and assuming that the voice service has the highest priority, the first target network configuration information may be Y2, because Y2 makes the service quality of the voice service of slice network 2 the highest.

Of course, the policy control network element may also determine the first target network configuration information according to service priority information and slice network priority information. For example, the first target network configuration information is such that the service with the highest service priority in the slice network with the highest slice network priority can achieve the best service quality. Taking Table 13 as an example, it is assumed that the slice network 1 has the highest priority and the service priority of the voice service is the highest. In this case, the first target network configuration information may be Y2.

In other embodiments, in a case where the policy control network element can also receive the use priority information of the network configuration information sent by the data analysis network element, the policy control network element can directly according to the network configuration information of each group. Use the priority to select the first target network configuration information. The first target network configuration information may be the network configuration information with the highest priority among the plurality of sets of network configuration information.

In the above embodiment, the first target network configuration information may be a group of network configuration information in the multiple groups of network configuration information. In other embodiments, the first target network configuration information may also be multiple sets of network configuration information. For example, assuming the corresponding S ₁ group network configuration information of each slice network, the first target network configuration information may be S ₂ group network configuration information in the S ₁ group network configuration information, where S ₁ is a positive integer greater than 2 , S2 is a positive integer greater than or equal to 1 and less than or equal to S ₁ . For the method for determining multiple sets of network configuration information as the first target network configuration information, reference may be made to the foregoing method for determining one set of network configuration information as the first target network configuration information, and details are not described herein again.

In some embodiments, the method shown in FIG. 2 may further include step 204.

204. The network management network element sends notification information to the policy control network element, and the notification information is used to notify the policy control network element that the network management network element cannot perform network configuration according to the network configuration information corresponding to the sliced network list. Correspondingly, the policy controls the network element to receive the notification information sent by the network management network element.

In some embodiments, the network management network element may send the notification information according to the access network resources and / or core network resources that cannot meet the network configuration information corresponding to the sliced network list.

In some embodiments, before step 204, the policy control network element may further send first indication information to the network management network element, where the first indication information is used to indicate that the network management network element is unable to When network configuration is performed on the corresponding network configuration information, the notification information is sent to the policy control network element. Correspondingly, before step 204, the network management network element receives the first instruction information.

In some embodiments, when the network management network element receives the network configuration information corresponding to the slice network list sent by the policy control network element, if the network management network element determines that the network cannot be networked according to the network configuration information corresponding to the slice network list If set, the network management network element can immediately send notification information to the policy control network element. In other words, after receiving the network configuration information corresponding to the sliced network list, the network management network element first determines whether the network configuration information corresponding to the sliced network list can be used for network settings. If it is determined that the sliced network list corresponds to If the network configuration information cannot be used for network settings, the notification information is sent to the policy control network element.

In other embodiments, after the network management network element receives the network configuration information corresponding to the slice network list sent by the policy control network element, if the network management network element determines that it cannot If the corresponding network configuration information is used for network settings, the network management network element can send notification information to the policy control network element. In other words, when the network management network element receives the network configuration information corresponding to the slice network list sent by the policy control network element, it may first perform network settings according to the network configuration information corresponding to the slice network list, but the slice network runs for a period of time. Afterwards, the network management network element finds that it is no longer possible to perform network settings based on the network configuration information corresponding to the sliced network list, such as in scenarios such as shortage of network resources, then the network management network element sends the notification information to the policy control network element at this time.

In some embodiments, the notification information further includes reason information, and the reason information is used to indicate a reason why the network management network element cannot perform network configuration.

In some embodiments, before step 204, the policy control network element may further send second instruction information to the network management network element, where the second instruction information is used to indicate that the network management network element is unable to When the corresponding network configuration information is used for network configuration, the reason why the network management network element cannot perform network configuration is sent to the policy control network element. Correspondingly, before step 204, the network management network element receives the second instruction information.

In some embodiments, the cause information may specifically indicate which network configuration parameters in the network configuration information cannot be met, for example, the average delay requirement or other network configuration parameters cannot be met. Examples of the other network configuration parameters are shown in Table 20.

In other embodiments, the cause information may further indicate an internal cause that these network configuration parameters cannot be met. For example, the cause information may include that the average delay requirement cannot be met due to insufficient access network buffer resources. Another example is that the current user capacity cannot be carried due to insufficient CPU resources of the AMF, or the delay of the N3 interface cannot meet the requirements due to insufficient link capacity of the N3 interface.

In some embodiments, the notification information may further include a network parameter measurement value corresponding to the sliced network list. The network parameter measurement value corresponding to the slice network list is a network parameter measurement value of the slice network in the slice network list. The network parameter measurement value may be a specific measurement value of all or part of the network configuration parameters listed in Table 20, for example, a specific measurement value including an average delay, a measurement value of a downlink packet loss ratio, an average or maximum wireless Resource control (radio resource control, RRC) connection number measurement value, etc.

In some embodiments, before step 204, the policy control network element may further send third instruction information to the network management network element, where the third instruction information is used to indicate that the network management network element is unable to When the corresponding network configuration information is used for network configuration, a network parameter measurement value corresponding to the sliced network list is sent to the policy control network element. Correspondingly, before step 204, the network management network element receives the third instruction information.

In other embodiments, the network management network element may separately send the notification information, the cause information, and / or a network parameter measurement value corresponding to the sliced network list.

To explain, this embodiment of the present application does not exclude that after receiving the network configuration information corresponding to the sliced network list sent by the policy control network element, the network management network element sends to the policy control network element the information corresponding to the sliced network list. The network configuration information is used to perform notification of network settings, or to send notification information that network settings have been successfully performed according to the network configuration information corresponding to the sliced network list.

As described above, in some embodiments, the network configuration information corresponding to the slice network list sent by the policy control network element to the network management network element may be all the network configuration information in the plurality of sets of network configuration information. In this case, after receiving the notification information sent by the network management network element, the policy control network element may request the data analysis network element again to obtain the network configuration information corresponding to the slice network list, and correspond to the newly obtained slice network list. The network configuration information is sent to the management network element.

In other embodiments, the network configuration information corresponding to the sliced network list sent by the policy control network element to the network management network element may be a set of network configuration information (i.e., the first target network configuration) among multiple sets of network configuration information. information). In this case, after receiving the notification information sent by the network management network element, the policy control network element may determine the second target network configuration information, which is different from the first target network configuration information.

In some embodiments, the policy control network element may determine that any set of network configuration information other than the first target network configuration information in the plurality of sets of network configuration information is the second target network configuration information.

In other embodiments, when the policy control network element obtains the configuration effect information, the policy control network element may determine the second target network configuration information according to the configuration effect information, for example, the second target network configuration information is In addition to the first target network configuration information, a set of network configuration information with the best service quality effect. The configuration effect information corresponding to the second target network configuration information and the method for the policy control network element to determine the second target network configuration information based on the configuration effect information may refer to step 201, and details are not described herein again.

In other embodiments, if the notification information further includes cause information, the policy control network element may determine the second target network configuration information according to the cause information. For example, if the reason information is that the average delay requirement cannot be met, the policy control network element may select another group of network configuration information with a lower average delay requirement as the second target network configuration information.

In other embodiments, if the notification information also includes a measurement value of the network configuration information, the policy control network element may determine the second target network configuration information according to the measurement value of the network configuration information. For example, if the specific measurement value of the average delay is included in the notification information and the measured value of the packet loss rate of the downlink data packet is 3%, the policy controls the network element to select a group of average delay requirements greater than 5 ms and the packet loss rate of the downlink data packet. More than 3% of network configuration information is required as the second target network configuration information.

In some embodiments, the method shown in FIG. 2 may further include step 205.

205. The policy control network element may request again from the data analysis network element to obtain network configuration information corresponding to another slice network list, where the other slice network list includes one or more slice networks. Correspondingly, the data analysis network element sends the network configuration information corresponding to another slice network list to the policy control network element.

In some embodiments, the network configuration information corresponding to the sliced network list sent by the policy control network element to the network management network element may be all the network configuration information in the plurality of sets of network configuration information. In this case, after receiving the notification information sent by the network management network element, the policy control network element can request the data analysis network element again to obtain the network configuration information corresponding to another slice network list, where the other slice network list contains one Or multiple slice networks. Correspondingly, the policy control network element may receive the network configuration information corresponding to another slice network list sent by the data analysis network element, and the network configuration information corresponding to the other slice network list may also be one or more types of network configuration information . The process of re-requesting and obtaining network configuration information corresponding to another sliced network list can completely reuse the methods of steps 201-202 described above, and will not be repeated here.

In some embodiments, before requesting to obtain the network configuration information corresponding to another slice network list, the policy control network element may first determine the other slice network list according to the slice network priority information and / or service priority information. Quality of service requirements.

For ease of description, the slice network list requested to obtain network configuration information in step 201 is hereinafter referred to as slice network list 1, and the other slice network list is referred to as slice network list 2.

In some embodiments, the policy control network element may determine a service quality requirement of another slice network list according to slice priority information. Specifically, the policy control network element can determine the slice networks included in slice network list 1 and slice network column 2 according to the slice priority information, and then determine the service quality requirements of slice network list 1 and the service quality requirements of slice network list 2. . The slice networks included in the slice network list 1 may be determined according to a first preset priority value, and the slice networks included in the slice network list 2 may be determined according to a second preset priority value. Here, the first preset priority value and the second preset priority value refer to a priority value in the slice network priority information. In some embodiments, the first preset priority value is greater than the second preset priority value. In this case, the slice network list 2 may be a subset of the slice network list 1. Taking Table 9 as an example, assuming that the first preset priority value is 3, the slice network list 1 includes slice network 1, slice network 2, slice network 3, and slice network 4. Assuming that the second preset priority value is 2, the slice network list 2 includes slice network 1, slice network 2, and slice network 3.

In other embodiments, the policy control network element may determine the service quality requirement of another slice network list according to the service priority information. Specifically, the policy control network element may determine, based on the service priority information, each slice in the service quality requirements corresponding to each slice network in the service quality requirements of slice network list 1 and each slice in the service quality requirements in slice network list 2 The services included in the service quality requirements corresponding to the network, and the service quality requirements of the services in the service quality requirements corresponding to each slice network in the slice network list 1 and the service quality requirements in the slice network list 2 are determined. The service quality requirements of the service in the service quality requirements corresponding to the slice network. The service requested by each slice network in the slice network list 1 may be determined according to a third preset priority value, and the service requested by each slice network in the slice network list 2 may be determined according to a fourth preset priority value. Here, the third preset priority value and the fourth preset priority value are priority values in the service priority information. In some embodiments, the third preset priority value is greater than the fourth preset priority value. In this case, the services requested by each slice network in slice network list 2 are a subset of the services requested by each slice network in slice network list 1. Taking Table 10 as an example, assuming that the third preset priority value is 3, the service quality requirements corresponding to each slice network in the slice network list 1 include the service quality requirements of service 1 and service quality requirements of service 2. 2. The service quality requirements of service 3 and the service quality requirements of service 4. Assuming that the fourth preset priority value is 2, the service quality requirements corresponding to each slice network in the slice network list 2 include the service quality requirements of service 1, the service quality requirements of service 2, and the service quality requirements of service 3.

Of course, the policy control network element may also determine the service quality requirements of the slice network list 1 and the service quality requirements of the slice network list 2 according to the slice network priority information and the service priority information. Taking Table 11 as an example, it is assumed that the first preset priority value is 3, the second preset priority value is 2, the third preset priority value is 3, and the fourth preset priority value is 1. . In this case, the slice network list 1 includes service quality requirements for services 1 to 3 of slice network 1, service quality requirements for services 1 to 3 of slice network 2, and service quality requirements for services 1 to 3 of slice network 3.

Or multiple service quality requirements of the sliced network list shown in Table 2 or multiple service quality requirements of the sliced network list shown in Table 4 or multiple service quality requirements of the sliced network list shown in Table 5.

It can be understood that the service quality requirements of different slice network lists may be different. The difference here may mean that the number of slice networks included in the service quality requirements of different slice network lists is different, but the service quality requirements corresponding to the same slice network may be the same. For example, Table 2 is a service quality requirement of one slice network list among the service quality requirements of the plurality of slice network lists, and Table 21 is a service quality requirement of another slice network list of the plurality of slice network lists.

Table 21

As shown in Table 21, the service quality requirements of the slice network list include service quality requirements corresponding to slice network 1 and service quality requirements corresponding to slice network 2.

Of course, the difference here may also mean that the number of slice networks included in the service quality requirements of different slice network lists and the service quality requirements corresponding to each slice network are different. For example, Table 2 is a service quality requirement of one slice network list among the service quality requirements of the plurality of slice network lists, and Table 23 is a service quality requirement of another slice network list of the plurality of slice network lists.

Table 23

As shown in Table 23, the service quality requirements of the slice network list include the service quality requirements corresponding to the slice network 1 and the service quality requirements corresponding to the slice network 2.

For example, the policy control network element may determine that the network configuration information corresponding to the first slice network list can meet the service quality requirements corresponding to several high-priority slice networks, that is, the network configuration information corresponding to the first slice network list It can meet the service quality requirements of a slice network with a priority value less than a preset priority value. Specifically, the preset priority value is set by a policy control network element according to a network resource state and an internal policy. For example, when network resources are sufficient or a specific value, the preset priority value may be set to a first priority value, and the first priority value may be a maximum value of the priority. In this case, the first slice network list may be composed of all slice networks. Taking Table 9 as an example, the first priority value may be 4. Assuming that the preset priority value is the first priority value, the first slice network list is composed of slice networks with a priority value less than 4. Correspondingly, the network configuration information corresponding to the first slice network list can meet service quality requirements corresponding to slice networks with a priority value less than 4. When the network resource is limited or is another specific value, the preset priority value may be set as a second priority value, and the second priority value is smaller than the first priority value. In this case, the first slice network list may be composed of slice networks whose priority value is less than or equal to the second priority value. Taking Table 9 as an example, assuming that the preset priority value is 3, the first slice network list may include slice network 1, slice network 2, and slice network 3. Accordingly, the network configuration information corresponding to the first slice network list can meet the service quality requirements corresponding to slice network 1, slice network 2, and slice network 3.

For example, the policy control network element may determine that the network configuration information corresponding to the first slice network list can meet the service quality requirements of services whose service priority value is less than a preset priority value. For example, when network resources are sufficient or a specific value, the preset priority value may be set to a first priority value, and the first priority value may be a maximum value of the priority. In this case, the network configuration information corresponding to the first slice network list can meet the service quality requirements of all services. Taking Table 10 as an example, the first priority value may be 4. It is assumed that the preset priority value is the first priority value. The network configuration information corresponding to the first slice network list can meet the service quality requirements of services with a priority value less than 4. When the network resource is limited or is another specific value, the preset priority value may be set as a second priority value, and the second priority value is smaller than the first priority value. In this case, the network configuration information corresponding to the first slice network list can meet the service quality requirements of services whose priority value is less than or equal to the second priority value. Taking Table 10 as an example, assuming that the preset priority value is 3, the service quality requirements of services with priority values less than or equal to 3 can be requested. In this case, the network configuration information corresponding to the first slice network list can meet the service quality requirements of service 1, service 2, and service 3.

In some embodiments, the policy control network element may determine the first slice network from the network configuration information corresponding to each slice network list sent by the data analysis network element according to the slice network priority information and service priority information.

For example, the policy control network element may determine that the network configuration information corresponding to the first slice network list can meet the service quality requirements corresponding to several high-priority slice networks, that is, the network configuration information corresponding to the first slice network list It can meet the service quality requirements of a slice network with a slice network priority value less than a preset priority value. Specifically, the preset slice network priority value is set by a policy control network element according to a network resource state and an internal policy. For example, when network resources are sufficient or a specific value, the preset slice network priority value may be set to the first slice network priority value, and the first slice network priority value may be the largest slice network priority. value. In this case, the first slice network list may be composed of all slice networks. When the network resource is limited or is another specific value, the preset slice network priority value may be set as a second slice network priority value, and the second slice network priority value is smaller than the first slice network priority value. In this case, the first slice network list may be composed of slice networks whose slice network priority value is less than or equal to the second slice network priority value.

Further, the policy control network element may determine that the network configuration information corresponding to the first slice network list can meet the service quality requirements of a service whose service priority value is less than a preset priority value. For example, when network resources are sufficient or a specific value, the preset service priority value may be set to a first service priority value, and the first service priority value may be a maximum value of the service priority. In this case, the network configuration information corresponding to the first slice network list can meet the service quality requirements of all services. The network configuration information corresponding to the first slice network list can meet the service quality requirements of services whose service priority value is less than 4. When the network resource is limited or is another specific value, the preset service priority value may be set as a second service priority value, and the second service priority value is smaller than the first service priority value. In this case, the network configuration information corresponding to the first slice network list can meet the service quality requirements of services whose service priority value is less than or equal to the second service priority value.

Taking Table 11 as an example, assuming that the preset slice network priority is 2 and the preset service priority is 2, the network configuration information corresponding to the first slice network list can meet the service quality of service 1 of slice network 1. The requirements are the service quality requirements of service 2 of slice network 1, the service quality requirements of service 1 of slice network 2, and the service quality requirements of service 2 of slice network 2.

For example, the policy control network may randomly determine that the network configuration information corresponding to a slice network list in the plurality of slice network lists is the network configuration information corresponding to the first slice network list. As another example, the policy control network element may determine that a group of network configuration information having the largest number of network configuration information groups is the network configuration information corresponding to the first slice network list. As another example, the policy control network element may determine the network configuration information corresponding to the first slice list according to a request message sent by the network management network element. The request message may include a slice network identifier included in the slice network list to be obtained. Take slice network list 1 and slice network list 2 as examples. Assuming that the request message includes slice network 4, the network configuration information corresponding to the first slice network list is the network configuration information corresponding to slice network list 2. Alternatively, the network configuration information corresponding to the first slice network list is network configuration information corresponding to the slice network 4.

In other words, after receiving the network configuration information corresponding to the first slice network list, the network management network element first determines whether the network configuration information corresponding to the first slice network list can be used for network settings. If it is determined that the network configuration information corresponding to the first slice network list cannot be used for network setting, the notification information is sent to the policy control network element.

In other embodiments, after the network management network element receives the network configuration information corresponding to the first slice network list sent by the policy control network element, if the network management network element determines that it cannot If the network configuration information corresponding to the first slice network list is used for network setting, the network management network element may send notification information to the policy control network element. In other words, when the network management network element receives the network configuration information corresponding to the first slice network list sent by the policy control network element, it may first perform network settings according to the network configuration information corresponding to the first slice network list. However, after the slice network runs for a period of time, the network management network element finds that it is no longer possible to perform network settings according to the network configuration information corresponding to the first slice network list. For example, in scenarios such as shortage of network resources, the network management network element only applies this policy at this time. The control network element sends the notification information.

It is worth noting that for the convenience of description, this embodiment only uses specific network element entities such as PCF, NWDAF, and OAM as examples, but it does not exclude that these entities can be replaced by other network element entities with equivalent or similar functions. Instead, for example, the PCF in this embodiment may be replaced by another network element having the policy control function according to the present invention, for example, the PCF is replaced by an NSSF or a network storage function (network storage function (NRF) network element or management plane policy control network element). Replace; NWDAF can be replaced by other network elements with the data analysis function of the present invention, such as NWDAF by management data analysis service (MDAS) network element; OAM can be replaced by other network management with the present invention Functional network elements are replaced, such as OAM is replaced by NSMF.

501. The PCF sends an analysis information request message to the NWDAF, where the analysis request message is used to request network configuration information corresponding to the first slice network list. Correspondingly, the NWDAF receives the analysis information request message sent by the PCF.

The difference between the method in this embodiment and the method in the embodiment shown in FIG. 4 lies in that the analysis request message is used to request network configuration information corresponding to the first slice network list, and will be directly sent to OAM by NWDAF.

The analysis information request message carries identification information of one or more slice networks included in the first slice network list. Specifically, the identification information of a slice network in this embodiment is a specific S-NSSAI.

The range of the slice network requirement is 1 to M, which indicates that the first slice network list may include 1 to M slice networks, where each slice network is identified by a specific S-NSSAI. The range of the service requirement list is 1 to N, which indicates that a specific slice network includes 1 to N services, where each service is distinguished by a service ID (application ID). In addition, the service quality requirements of each service are requirements for the proportion of users who meet the single user service quality requirements of the service, that is, the user satisfaction requirements of the service. Whether it is required refers to whether the content of the corresponding entry is required or optional.

In this step, the PCF sending the analysis information request message to the NWDAF may specifically belong to a real-time request message (for example, Nnwdaf_AnalyticsInfo_Request) or a subscription request message (for example, Nnwdaf_AnalyticsInfo_Subscribe). If the analysis information request message is a real-time request message, after receiving the request message, NWDAF can immediately feedback the content of the PCF request to OAM without the model training operation described in step 202, and the model training operation is receiving the request message. It has been done before; if the analysis information request message is specifically a subscription request message, after receiving the request message, NWDAF needs to undergo model training before it can feed back the content requested by the PCF to OAM.

It is worth noting that in this embodiment, the analysis information request message sent by the PCF includes identification information of one or more slice networks included in the first slice network list, and the first slice network list is determined by NWDAF Corresponding service quality requires information methods. This embodiment does not exclude that the analysis information request message sent by the PCF directly includes the service quality requirements of the first slice network list.

502. The NWDAF sends network configuration information corresponding to the first slice network list to the OAM. Correspondingly, the OAM receives network configuration information corresponding to the first slice network list sent by the NWDAF.
