Description

This application requires the priority of the Chinese patent application submitted to the State Intellectual Property Office on November 06, 2018, with the application number 201811314710.6 and the application name "A method and device for processing user access in network slices" Incorporated by reference in this application.

Technical field

Embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for processing user access in network slicing.

Background technique

The fifth generation (5-Generation, 5G) mobile communication technology network (referred to as: 5G network) introduced the concept of network slice (NS) to cope with the difference in network performance requirements of different communication services, that is, 5G network will The actual network divides resources and functions to form different network slices to meet these different needs, which can reduce network operation investment costs and enrich network operation models.

Currently, for network slicing of different tenants, the network management device determines the service level agreement (SLA) template of the network slicing of different tenants according to the service level requirements of each tenant, and deploys the corresponding network slicing according to the SLA template .

However, the granularity of the SLA template determined by the network management device based only on the service level requirements of each tenant is very coarse, and it is difficult to guarantee the performance of network slicing. At the same time, when the network management device allocates network resources to the network slices of different tenants, if the general resource deployment situation is determined according to the SLA template, this may cause the problem of waste of resources or insufficient deployment resources, thereby reducing the performance of network slices. In addition, the service level agreement to guarantee network slicing is mainly to guarantee the tenant's business satisfaction requirements for a certain business within the network slicing.

At present, when the network resources are insufficient to meet the requirements of all network slicing, the policy control network element will determine a slicing request list for indicating the satisfaction requirements of the service based on the priority of the network slicing, local operator policy, etc. The corresponding network slice KPI list result is sent to the operation management and maintenance (operation, administration and maintenance, OAM) network element. OAM adjusts the network configuration based on the results of the Network Slice KPIs list to ensure Slice SLA. If the network configuration is adjusted through OAM to protect the Slice, such as the following problem: the current network management network configuration, a common method is to expand and reduce capacity through NFV and other means, only applicable to core network equipment, not applicable to access network equipment, and The key factor currently affecting the business experience in network slicing is still the air interface, so solutions based on the management plane may not help.

It should be understood that when a terminal can access the system shown in FIG. 1 through an access network device, a network element (eg, slice management control network element 20) in the 5G core network (5G core network (5GC)) allocates one or more Network slices. Each network slice may include one or more of UPF network elements, SMF network elements, NRF network elements, and PCF network elements. Some network functions can be shared among the multiple network slices. The collection of shared network functions can be referred to as common control network function (Common Control Network Function, CCNF). For example, CCNF may include one or more of AMF network elements and NSSF network elements. Each network slice corresponds to at least one access network device.

In addition, as shown in FIG. 2, the 5G network may further include: session management function (SMF) network elements, access and mobility management function (AMF) network elements (AMF) network elements, and strategies control function (Policy control function, PCF) network element, user plane functions (user plane function, UPF) network element, an application function (application function, AF) NE, the UDF NE, operation (operator) AF NE, 3 ^rd AF network element, access device (for example, access network (AN)), authentication server function (AUSF) network element, network capability open function (NEF) network element, network Network storage function (NRF) network elements and data network (DN), operation, administration and maintenance (OAM) network elements (also called operation management and maintenance network elements), etc., This embodiment of the present application does not specifically limit this.

As shown in Figure 2, OAM network elements can cover the network elements of the access network and the core network, and can collect data from these network elements of the access network and the core network.

The difference is that: 3rd AF network elements (such as WeChat service server and Alipay payment service server) are not controlled by operators, and operator AF network elements (such as the proxy-call session control function (proxy- call session control function, P-CSCF ) NE) NEs need NEF by operator control, 3 ^rd AF NWDAF NE NE and interactive.

It should be noted that the name of the interface between each network element in FIG. 2 is only an example, and the name of the interface in the specific implementation may be other names, which is not specifically limited in this embodiment of the present application.

It should be noted that the access device, AF network element, AMF network element, SMF network element, AUSF network element, UDM network element, UPF network element, and PCF network element in FIG. 2 are only a name, and the name does not affect the device itself. Composition limitation.

For example, the UDM network element may also be replaced with a user home server (HSS) or a user subscription database (USD) or a database entity, etc., and will be described here in a unified manner, and will not be repeated hereafter. .

As shown in FIG. 3, an embodiment of the present application provides a method for processing user access in a network slice. The method includes:

Step 101: The slice management control network element obtains first information corresponding to at least one network slice, where the at least one network slice includes the first network slice.

It should be understood that the first information corresponding to at least one network slice includes: first information corresponding to each network slice in at least one network slice.

Exemplarily, the first network slice is a newly created network slice or a network slice without a service level agreement SLA. The first network slice may represent a network slice, or a group of newly created or unsigned SLA network slices, or multiple network slices of the same type.

Exemplarily, the first information of a network slice is used to determine the first indication information of the network slice. For example, the first information of a network slice includes identification information of the network slice, and at least one of the following information corresponding to the network slice: time information, area information, and the first maximum number of registered users in the network slice (MaximumRegistrationUsers ), Information of at least one service of network slicing. Among them, the service information is used to determine the status of the service, that is, the current network meets the service.

It should be understood that, in addition to the identification information of the network slice, the first information of any network slice may also include: time information, area information, the first maximum number of registered users in the network slice, and information of at least one service of the network slice at least one.

It should be understood that the service information includes at least one of the following information of the service: Service ID (Application ID), the first maximum number of users (Maximum Users for the Application, that is, the maximum number of users of the service that the current network can satisfy), the first An average service experience (Average Service MOS, that is, the average service experience of the service that the current network can satisfy), first service experience interval information (Service MOS Range, that is, the service experience interval of the service that the current network can meet), first Business satisfaction (How many percentage UE's experience should be satisfied, that is, the user satisfaction of the business that the current network can meet).

Exemplarily, the first maximum number of registered users is used to indicate the maximum number of users that can currently be registered in the network slice, that is, the maximum number of registered users that the current network can satisfy the network slice.

Exemplarily, the time information in the first information is used to indicate to the slice management control network element the time period of the first information of the network slice. For example, the time information may be a time window (Time Window), time stamp (Timestamp), time period (Time Interval).

For example, the first information is from March 1, 2018 to March 8, 2018. In this way, the first information can determine that the first information of the network slice is the first information obtained by the data analysis network element corresponding to March 1, 2018 to March 8, 2018.

The area information in the first information is used to indicate to the slice management control network element an area that can support the network slice.

Exemplarily, the area information may be a tracking area (tacking area, TA) or a TA list or a routing area (routing area, RA) or RA list, or a cell or cell list.

Specifically, when the first information of a network slice includes: time information, area information, the maximum number of registered users in the network slice, and information of at least one service of the network slice, the first information of the network slice is used for slice management control The network element determines the service information of the at least one service on the network slice in the specified area and the first maximum number of registered users in the specified time period. Specifically, when the first information of a network slice includes: time information, area information, and information of at least one service of the network slice, the first information of the network slice is used by the slice management control network element to determine a specified area within a specified time period Service information of at least one service on the network slice.

It should be understood that before step 101, the method provided in this embodiment of the present application further includes: the slice management control network element obtains demand information, where the demand information is used to indicate the quality requirement of at least one network slice.

Exemplarily, the demand information may include: at least one of identification information of the network slice, the second maximum number of registered users, and service requirement information of at least one service. Exemplarily, the service requirement information is used to indicate the tenant's requirement that the network can perform the service.

The second maximum number of registered users represents the maximum number of registered users required to register in the network slice. For example, 10 million.

Optionally, the demand information may further include: at least one of area information and time information. In addition, the demand information may also include bandwidth requirements, delay requirements, and so on.

Exemplarily, the AF network element sends the demand information to the slice management control network element through the PCF network element, that is, the slice management control network element obtains the demand information from the AF network element managed by the tenant through the PCF network element. Or the demand information may be configured by the operator on the slice management control network element. Or the demand information may be sent by the network management network element to the slice management control network element. Optionally, the AF network element can be managed by the slice tenant.

The identification information of the network slice in the embodiment of the present application may be: single network slice selection support information (Single Network Slice Selection Selection Information, S-NSSAI) or network slice selection support information (Network Slice Selection Selection Assistance Information, NSSAI) or NSI ID.

Exemplarily, the service requirement information includes: service identification (Application ID), second maximum number of users (Required Maximum Users for the Application, that is, the maximum number of users of the service that the tenant requires the network to meet), and the second average service experience ( RequiredAverageServiceMOS, that is, the average service experience of the service that the tenant requires the network to meet), the second service experience interval information (Requested Service MOS range, that is, the service experience interval of the service that the tenant requires the network to meet), and the second At least one of business satisfaction (How many percentage UE's experience should be satisfied, that is, the user satisfaction of the business that the tenant requires the network to meet).

The second maximum number of users represents the maximum number of users in a service, that is, the total number of services using a certain service. For example, 10000.

Among them, the service identifier is used to identify the service in the slice.

The second service experience interval information is used to indicate service experience requirements in the service.

Exemplarily, the service in the network slice may be a voice service as an example, and the range of the second MOS is [0.0, 5.0]. For example, the second MOS is greater than or equal to 3.0 and less than or equal to 5.0 to meet the voice service experience requirements , That is, MOS = 3.0 is the minimum requirement to meet the voice service experience. In the case where the MOS score is greater than or equal to 3.0, the MOS may be increased according to the good degree, and the MOS may be 4.0, 4.5, 5.0, and so on. Among them, the higher the MOS value, the stricter the QoS parameter requirements for the corresponding voice service, and the higher the network quality requirements. In the final analysis, the higher the network resource requirements, the higher the network slice resource requirements.

The second service satisfaction is used to indicate the proportion of the total number of services required by the service tenant to satisfy the second service experience interval information in the service. Optionally, the ratio is a first threshold, that is, the ratio of the number of services that the tenant requires in the service that satisfies the second service experience interval information to the total number of services is greater than or equal to the first threshold. The embodiment of the present application does not limit the first threshold.

For example, tenants usually put forward business satisfaction requirements to operators. For example, for voice services, the proportion of services requiring MOS greater than or equal to 3.0 to the total number of services is greater than or equal to 95%.

Step 102: The slice management control network element determines first indication information corresponding to each network slice in the at least one network slice according to the first information corresponding to the at least one network slice, where the first indication information is used to indicate the corresponding The relationship between the slice quality and the quality requirements of the network slice.

Specifically, step 102 may be implemented in the following manner: the slice management control network element determines the first indication information of any network according to the first information corresponding to any one of the at least one network slice and the quality requirements corresponding to any one of the network slices .

Exemplarily, the first indication information is determined by the first information of the network slice and the slice quality required by the quality of the network slice.

Exemplarily, assuming that there is only one service for a network slice, the tenant requires a service experience (that is, Service MOS) higher than 4.0, and requires more than 95% of user service satisfaction. There are two cases of slice operation quality information:

In the first case, the slicing management control network element determines that the network can meet the quality requirements of the network slicing 120%, that is, the service MOS in the first information of the network slicing is 4.8, and there is 98% user service satisfaction. In this case, the slice quality corresponding to the network slice is higher than the slice quality required by the network slice quality requirements, which can be referred to as overfitting.

In the second case, the slicing management control network element determines that the network can meet the quality requirements of network slicing 80%, that is, the service MOS in the first information of the network slicing is 3.2, and 76% of users have business satisfaction. In this case, the slice quality corresponding to the network slice is lower than the slice quality required by the network slice quality requirements, which may be referred to as underfitting.

It is worth noting that, first of all, the above embodiment is only one of the methods for determining the slice quality information. Specific more complex scenarios, such as the presence of multiple services in multiple network slices, need to design more complex algorithms, which belong to Data analysis network element internal product realization. Then, in the actual operation process, the introduction of a new network slice or an unsigned slice SLA slice may affect the running quality of the existing network slice, so when determining the quality indication information of a network slice, the network is also processed In addition to the first information of the slice itself, it is optional to refer to the first information of other network slices.

Exemplarily, slice quality information (slice quality information) corresponding to a network slice is used to indicate the degree to which the current network meets the SLA of the network slice, that is, the slice quality of the network slice.

Exemplarily, since the slice quality information of the slice management control network element indicates the degree to which the current network meets the SLA of the network slice, usually expressed as a percentage (for example, the degree to which the current network meets the SLA of the network slice is 90%), the quality of the network slice The requirement is also expressed as a percentage, so the first indication information can be determined according to the size between the slice quality indicated by the slice quality information corresponding to the network slice and the slice quality indicated by the quality requirement.

Exemplarily, the relationship between the slice quality corresponding to the network slice and the quality requirement of the network slice includes: the slice quality corresponding to the network slice is higher than the slice quality required by the network slice quality requirement, or the slice quality corresponding to the network slice is lower than The quality of the network slice requires the required slice quality, or the slice quality corresponding to the network slice is equal to the slice quality required by the quality requirement of the network slice. As explained by the value, the slice quality corresponding to the network slice is equal to the slice quality required by the network slice quality requirements, and does not mean that the two are completely equal, as long as the two are close or the slice quality corresponding to the network slice is above and below the network slice quality requirements The floating degree is not large, and can be understood as equal.

Specifically, step 102 may be specifically implemented in the following manner: the slice management control network element determines the first indication information corresponding to each network slice according to the first information corresponding to each network slice in the at least one network slice and the pre-configuration policy .

Exemplarily, the pre-configuration strategy may be a requirement for the maximum number of registered users in the network slice. When deciding the first indication information of the network slice, the size relationship between the first maximum number of registered users that can meet the network slice and the second maximum number of registered users in the network slice is considered in the current network. The size relationship can be higher, lower, equal, or close.

For example, the slice management control network element determines the first indication information corresponding to NS1 according to the first information corresponding to NS1 and the pre-configuration policy. The slice management control network element determines the first indication information corresponding to NS2 according to the first information corresponding to NS2 and the pre-configuration policy. The slice management control network element determines the first indication information corresponding to NS3 according to the first information corresponding to NS3 and the pre-configuration policy.

Step 103: The slice management control network element controls user access in the first network slice according to the first indication information of at least one network slice.

Since the number of users connected to each network slice in at least one network slice affects the slice quality of each network slice, step 103 may include the following meanings:

The slice management control network element controls user access in the first network slice according to the first indication information of the first network slice. Or, the slice management control network element controls user access in the first network slice according to the first indication information of other network slices in the at least one network slice except the first network slice.

Exemplarily, after acquiring the first indication information corresponding to each network slice other than the first network slice in the at least one network slice, the slice management control network element may use the first indication information corresponding to the at least one network slice and any task The mapping relationship between the quality requirements of a network slice controls the access of users in any network slice.

Controlling user access in any network slice in the embodiments of the present application may be understood as controlling the number of terminals accessed in one network slice.

It should be understood that the slice management control network element may, through step 103, make the slice quality of the first network slice meet the quality requirements of the first network slice. In addition, it can be ensured that the slice quality of other network slices in at least one network slice meets the quality requirements of other network slices.

Since the first network slice is a newly established network slice or a network slice without a service level agreement SLA, the slice management control network element can gradually control the number of users connected in the first network slice to avoid the existing signed Slice The impact of SLA's network slicing. Therefore, in order to gradually control the number of users connected in the first network slice, as shown in FIG. 4, as a possible implementation manner, step 103 may specifically be implemented in the following manner:

Step 1031: The slice management control network element determines that the slice quality of the first network slice is higher than the quality requirement of the first network slice, and the slice management control network element increases the number of users accessed in the first network slice. That is, the current network can exceed the quality requirements of the first network slice in excess, so it can continue to admit new users to the first network slice.

Exemplarily, the slice management control network element determines the quality requirements of the first network slice through an network management (OAM) instruction or operator configuration.

Exemplarily, the slice management control network element may determine the quality requirements of the first network slice according to the demand information obtained from the network management (OAM) instruction or the operator configuration.

Specifically, if the slice quality of the first network slice is higher than the quality requirements of the first network slice, it means that the access network device corresponding to the first network slice allocates excess air interface resources for the first network slice, and the first The SLA state of the network slice is recorded as the first state (for example, over or overfitting state).

For example, if the degree to which the network can meet the SLA of the first network slice is 95%, and the quality requirement of the first network slice is 90%, since 95% / 90% = 105.6%> 100%, it means that the first network slice The quality of the slice is greater than the quality requirement of the first network slice, or the air interface resources allocated by the access network device of the first network slice for the first network slice are excessive, which is recorded as the state of Slice overfitting.

Although the quality of the first network slice is higher than the quality requirements of the first network slice, there may be a first maximum number of registered users that the first network slice has accessed is greater than or equal to a second The maximum number of registered users. It is also possible that the first maximum number of registered users that the first network slice has accessed is less than the second maximum number of registered users that the first network slice is required to access. Therefore, step 1031 may also be implemented in the following manner:

The slice management control network element determines that the slice quality of the first network slice is higher than the quality requirement of the first network slice, and the first maximum number of registered users in the first network slice is less than the second maximum number of registered users, then the slice management control network element Increase the number of users accessed in the first network slice.

It should be understood that, in order to ensure the quality of service in the first network slice, when the slice management control network element increases the number of users accessed in the first network slice, it may control the final maximum number of registered users registered in the first network slice It is equal to the second largest number of registered users.

For example, if the slice management control network element determines that the ratio between the first indication information of the first network slice and the quality requirement of the first network slice is 120%, and the tenant requires the second maximum number of registered users in the first network slice Is 10 million users, but the first maximum number of registered users in the current first network slice is 1 million, indicating that the access network device allocates excess air interface resources for the first network slice, therefore, the first network slice can also be accessed More users.

Step 1032: The slice management control network element determines that the slice quality of the first network slice is lower than the quality requirement of the first network slice, and the slice management control network element reduces the number of users accessed in the first network slice. That is, the current network does not meet the quality requirements of the first network slice, so there may be a need to reduce users who are admitted to the network slice.

Specifically, if the slice quality of the first network slice is less than the quality requirement of the first network slice, it indicates that the access network device corresponding to the first network slice allocates insufficient air interface resources for the first network slice, and the first network The SLA state of the slice is recorded as the second state (for example, underfitting state).

Specifically, if the degree to which the network can meet the SLA of the first network slice is 80%, the quality requirement of the first network slice is 90%. Since 80% / 90% = 88.9%, this means that the air interface resources currently allocated by the access network device for the first network slice are insufficient, and are recorded as the Slice SLA underfitting state.

Although the slice quality of the first network slice is lower than the quality requirements of the first network slice, it is possible that the first maximum number of registered users in the first network slice is less than or equal to the second maximum number of registered users, or that the first network slice The first maximum number of registered users is greater than the second maximum number of registered users. Therefore, step 1032 may be specifically implemented in the following manner:

If the slice management control network element determines that the slice quality of the first network slice is lower than the quality requirement of the first network slice, if the slice management control network element determines that the first maximum number of registered users in the first network slice is greater than the second maximum registration Number of users, the slice management control network element reduces the number of users accessed in the first network slice. If the slice management control network element determines that the first maximum number of registered users in the first network slice is less than or equal to the second maximum registered user number, the slice management control network element keeps the number of currently accessed users in the first network slice unchanged.

It should be understood that the slice management control network element may make the number of users accessed in the first network slice after the reduction be less than or equal to the second maximum number of registered users.

Step 1033: The slice management control network element determines that the slice quality of the first network slice is equal to the quality requirement of the first network slice, and the slice management control network element maintains the same number of users accessed in the first network slice.

The slice quality of the network slice in the embodiment of the present application is equal to the quality requirement of the network slice means: the slice quality of the network slice is completely equal to the quality requirement of the network slice, or the error between the slice quality of the network slice and the quality requirement of the network slice is preset Within range. The preset range can be set according to needs, which is not limited in the embodiment of the present application.

In summary, since the newly added slice does not sign the Slice SLA, the slice management control network element can gradually control the number of users accessing the first network slice to avoid slicing the existing network that has already signed the Slice SLA Impact. For example, the first network slice can first allow the slice to access 1 million users, and then if the SLA of the first network slice is overfitted, that is, the business experience of the 1 million users can be fully satisfied and exceed tenant requirements, such as tenant requirements The second service satisfaction of service 1 is 90%, but the slice management control network element has found through observation that the first service satisfaction of service 1 in the first network slice reaches 95%, at which time the slice management control network element can allow The slice is connected to more users, for example, another 1 million users are added to the first network slice.

The process of the slice management control network element controlling user access to the network slice can refer to the description in the prior art, and the embodiments of the present application will not repeat them here. In the terminal registration process, the slice management control network element can notify the AMF of the network slice type that the terminal can access, namely Allowed S-NSSAI (s), and then when the terminal subsequently establishes a session, in the Allowed S-NSSAI (s) Select a network slice type as the network slice type for the session. That is to say, if the slice management and control network element allows the terminal to access a certain network slice, it only needs to fill the type of the network slice into Allowed S-NSSAI, and then send it to the terminal.

In some embodiments, the slice management control network element may obtain the first information corresponding to each network slice from the data analysis network element. Therefore, as shown in FIG. 5, before step 101, the method provided in this embodiment of the present application further include:

Step 104: The slice management control network element sends a first request to the data analysis network element. The first request is used to request first information corresponding to each network slice in at least one network slice. The first request includes filter information (Filter information) The filtering information is used to indicate the range of acquiring the first information of each network slice.

It should be understood that the slice management control network element may send the first request to the data analysis network element through the interface with the data analysis network element.

That is, through step 104, the slice management control network element subscribes to the data analysis network element for the first information of at least one network slice in an area within a period of time (also known as statistical information, namely estimated statistics). At least one slice includes the first A network slice.

Exemplarily, the filtering information includes identification information of at least one network slice, and at least one of the following information corresponding to the at least one network slice: time information and area information.

It should be understood that the elements carried in the filtering information may be determined by the slice management control network element from the acquired demand information. The time information carried in the filtering information may be less than or equal to the time information in the demand information, or may be greater than or equal to the time information in the demand information. The area information carried in the filtering information may be less than or equal to the area information in the demand information, or may be greater than or equal to the area information in the demand information. This embodiment of the present application does not limit this.

Step 105: The data analysis network element receives the first request.

Step 106: The data analysis network element obtains first information corresponding to each network slice in at least one network slice according to the first request. The first information is used to determine the relationship between the network slice quality and the network slice quality requirements.

Exemplarily, the process of the data analysis network element acquiring the first information corresponding to each network slice in at least one network slice may be divided into the following steps:

Step 1. After a network slice is deployed, the services of the network slice start to run in the initial slice network. During the operation, the data analysis network element generates multiple sets of services for each service in at least one service corresponding to the network slice Quality QoS parameters. Each set of QoS parameters includes: guaranteed flow bit rate (Guaranteed Flow Bit Rate, GFBR), packet delay budget (Packet Delay Delay (PDB), packet error rate (Packet Error Rate, PER), average packet loss rate (Maximum One or more of Packet Loss Rate, Max PLR), Average Window Size (AWS), etc.

Exemplarily, step 1 can be implemented in the following manner:

Step 11. The data analysis network element can collect service data of quality of service (Quality of Service Flow, QoS) from the AF network element, and from network network elements (eg, RAN, AMF network element, SMF network element, UPF) Network element) to obtain network data.

Exemplarily, the service data involved in this application may be: bandwidth, delay, packet loss rate, jitter buffer, transmission control protocol (Transmission Control Protocol, TCP) congestion window, TCP receive window, media encoding type, media encoding Data such as rate and other parameters.

It can be understood that, in the embodiment of the present application, the data of a certain parameter may be the size, value, or requirement of the parameter. For example, the CQI data may refer to the size or value of the CQI. In the embodiment of the present application, the parameter data, size, or value or requirement expresses the data value of the parameter collected or obtained by the corresponding network element, as follows Any reference to such descriptions can be found here, and will not be repeated here.

The network data involved in this application can be any of the following parameters: bandwidth, delay, packet loss rate, reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), Block error rate (BLER) and channel quality indication (CQI), slice identification information, data network name (DNN) and other parameter data.

Exemplarily, the business data may be shown in Table 1, and the network data may be shown in Table 2:

Specifically, as shown in Table 1, the data analysis network element obtains service data corresponding to one or more services such as video service, payment service, automatic driving service, and vertical (vertical) service through the AF network element. Exemplarily, the data analysis network element may obtain network data from a 5G network function (NF).

Exemplarily, Table 1 illustrates the data content from tenant service experience data, and Table 2 illustrates the content of 5G NF network data. For details, see Table 1 and Table 2 below:

Table 1 Business data from tenant business experience data

Table 2 Network data derived from 5G NF

Step 12. The data analysis network element analyzes the network data and service data to obtain the Service MOS model for each service in the network slice.

Step 13. The data analysis network element obtains each service according to service requirements (ie, between MOS partitions, for example, [3.0, 4.0], [4.0, 4.5], [4.5, 5.0]) and the Service MOS model of each service At least one set of quality of service QoS parameters corresponding to different service experience intervals.

Step 2: The data analysis network element maps the geographic area where all services in the slice of the AF network element are mapped to the AF network element by Correlation ID according to the geographic area identifier (QoS) of the QoS flow in the business data and the TAI or Cell ID in the network data Correspondence with network areas (for example, TA ID, TA ID list, and cell ID list).

Step 3: The data analysis network element analyzes and obtains the business monitoring information of the slice in the geographic area, the user control information in the slice in the network area, and the business control information of the slice.

The user control information includes at least one of network area information and at least one network slice instance information, where the network slice instance information includes: identification information of the network slice instance, and the first maximum number of registered users.

The service control information includes at least one of network area information and at least one network slice instance information, wherein the network slice instance information includes identification information of the network slice instance and at least one service configuration information.

The service configuration information includes a service identifier, the first maximum number of services of the service, and at least one service experience interval information of the service.

The service experience interval information includes: the size of the service experience interval, the maximum number of services in the service experience interval, and at least one set of service quality QoS parameters in the service experience interval.

For a certain service, the reason is at least one set of QoS parameters. Exemplarily, considering the service experience requirements for vertical industries (such as business MOS score greater than 3.0), packet delay data and packet loss rate data are in conflict

For example, under weak coverage, the RAN can transmit a few more data packets to ensure the packet loss rate, but in this case, the packet delay will be increased, and further, the stream bit rate may be increased;

For example, under strong coverage, the RAN does not need to transmit multiple data packets. In this case, the packet loss rate and packet delay can be guaranteed. Further, the stream bit rate may be reduced. Therefore, for one service, there are one or more sets of QoS parameters.

Specifically, the data analysis network element obtains at least one set of QoS parameters of the service through a big data method based on time-varying network data or service data or terminal data and corresponding service experience data. The specific process can refer to step A and step B.

Step A: The data analysis network element obtains the service receipt from the AF network element, collects network data from network elements such as RAN equipment, UPF network element, UE, AMF network element, SMF network element, and PCF network element, and then passes the service identification and service Information such as flow identification, terminal identification, session identification where the service flow is located, associated identification, time, etc. on each network element associate data of each network element to obtain complete training data. The training data includes:

1), business experience data, from AF network elements.

2). Other time-varying parameter data that affects business experience data, including,

a. TCP congestion window data from the AF network element, TCP receive window data, jitter buffer data, media encoding type and encoding rate data, buffer data, data of at least one data type.

b. Stream bit rate data, packet loss rate data, delay data, wireless channel quality data, and data of at least one data type from the RAN network element.

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

d. Streaming bit rate data, packet loss rate data, delay data, data of at least one data type, TCP congestion window data, TCP receive window data, jitter buffer data, media encoding type and encoding rate data, buffer data from the UE , CPU occupancy rate, memory occupancy rate of at least one data type of data. and many more.

Step B, the NWDAF network element obtains the relationship model between the service experience and other time-varying parameter data that affects the service experience data based on the linear regression method, namely the service experience model, and the NWDAF network element can plan the business One or more sets of QoS parameters.

Exemplarily, as shown in Table 3, Table 3 shows the service monitoring information of the slice in the geographic area carried in the first request, as shown in Table 3 below:

Table 3 Contents of service monitoring information

Exemplarily, Table 4 shows the content of user control information, as shown in Table 4 below:

Table 4 User control information

Exemplarily, Table 5 shows the content of the service control information, as shown in Table 5 below:

Table 5 Service control information

Exemplarily, the service experience interval may be MOS ∈ [0, 3], [3.0, 4.0] in Table 5, and the maximum number of services in the service experience interval may be the service MOS ∈ [4.0, which can be accommodated in the cell in Table 5 5.0] Scope of business.

Exemplarily, the data analysis network element in the embodiment of the present application may obtain the corresponding MOS points during the service in the following manner:

Step 1. Data analysis The network element obtains the Service MOS model based on the business data and network data. Among them, the Service MOS model is used to characterize the relationship between the service experience (ie Service MOS) and network data.

It should be understood that, as shown in Table 1, the data analysis network element can obtain Qos flow-level service data from the AF network element and network elements in the 5GC (for example, RAN, AMF network element, SMF network element, UPF network element) Go to the network data and train to get the Service MOS model.

Exemplarily, the data analysis network element can obtain the Service MOS model according to the following formula (1).

H (x) = W0X0 + W1X1 + W2X2 + W3X3 + W4X4 + W5X5 + ... + WnXn. (1)

With reference to Table 5, X is a variable, X1 may be GFBR, X2 may be PDB, X3 may be PER, X4 may be network data X4, and X5 may be network data X5. Among them, Wn represents the weight of the nth variable, n represents the number of variables, and Xn represents the nth variable. n is an integer greater than or equal to 1. H (x) represents the Service MOS model.

Step 2. The data analysis network element obtains service QoS parameter recommendations based on the MOS requirements of the service and the Service MOS model.

Specifically, the MOS requirement of this service not only represents the tenant's demand, but also can be understood as QoE demand. For example, the MOS score is greater than or equal to 3.0.

For example, according to formula (1) and H (x) ≥3.0, the following matrix (1) can be obtained.

Among them, each row in the matrix (1) represents a set of QoS parameters. Among them, the QoS parameter recommendation of the service includes multiple sets of QoS parameters. Among them, each set of QoS parameters includes the values of GFBR, PDB, PER and other parameters.

Step 3: The data analysis network element can obtain the corresponding MOS points during the service based on the Service MOS model and network data. That is, the data analysis network element can calculate the MOS points through the network data input Service MOS model, as shown in Table 6 below:

Table 6

For example, based on the Service MOS model and the network data X4 (or network data X5), the data analysis network element can obtain that the corresponding MOS in the service is divided into 0 to 1.

Step 4. The data analysis network element obtains the business division model in the area.

As shown in Table 1 and Table 2, the data analysis network element obtains service data and network data, and then obtains the Service MOS model through the above step 1.

Schematic diagram of the training process of the service distribution model (taking Recurrent Neural Network, RNN) as an example. The service distribution model includes: a neural network input layer, a hidden layer, and a neural network output layer.

Specifically, for the input of the neural network input layer and the output parameters of the neural network output layer during the training of the service distribution model, refer to the following Table 7 and Table 8:

Table 7 Business Distribution Model Algorithm Input

It should be understood that the above Table 7 is only an example of the input of the service distribution model algorithm. In an actual process, the input of the service distribution model algorithm may further include more or less parameters than Table 7.

In this embodiment of the present application, the number of users of a service is the number of terminals using the service, and the number of users slicing is the number of terminals using the slice.

Table 8 Business distribution model algorithm output

Step 5. The data analysis network element obtains the QoE Requirement corresponding to Slice Load.

Step 5 may be specifically implemented in the following manner: the data analysis network element receives network area information (for example, Cell ID or Cell ID list) and the number of Slice Load levels from the NSSF network element. The data analysis network element receives the tenant's service satisfaction requirement from the PCF network element. For example, the proportion of service 1 whose MOS is greater than or equal to 3.0 is 85%.

For example, the number of Slice Load is 5, and the values of Slice Load of different Slice Load Level are different. The specific meaning of different values can be: 1 means very light load, 2 means light load, 3 means normal, and 4 means congestion , 5 means very congested.

The data analysis network element inputs the acquired QoE requirements, Slice Load, and network area information into the service distribution model. For example, slice A has service 1 and service 2, and slice B has service 3 and service 4. The slice level corresponding to service 1 is 1, and the proportion of service 1 whose MOS is greater than or equal to 3.0 is 85%. The slice level corresponding to service 2 is 2, and the proportion of service 2 whose MOS is greater than or equal to 3.5 is 92%.

The slice level corresponding to service 3 is 3, and the proportion of service 3 whose MOS is greater than or equal to 4.0 is 87%. The slice level corresponding to service 4 is 4, and the proportion of service 4 whose MOS is greater than or equal to 3.0 is 80%.

Step 6. The data analysis network element obtains QoE requirements for different services corresponding to different Slice Load levels.

Specifically, the data analysis network element executes the K-Means clustering algorithm based on the regional-level business information, where the size of K is equal to the number of Slice Loads, and the clustering result obtains K centroids, each centroid includes each business in the network Business satisfaction within. Then, the data analysis network element will receive the tenant's service satisfaction requirement from the PCF network element as Slice Load = Level 3 (normal vector), and then calculate the difference between K centroids and Slice Load Level = 3 (normal vector) Angle, and then further determine the QoE requirement range corresponding to Slice Load = 3 respectively.

As another embodiment of the present application, the data analysis network element in the present application may also determine the service configuration information corresponding to Slice Load in the following manner.

Specifically, the QoE Requirement corresponding to each Slice Load level obtained by the data analysis network element through the above process determines the Slice load level information (information) corresponding to the Slice Load level, as shown in Table 9 below:

Table 9 Slice Load Level information

In summary, the data analysis network element may summarize the service monitoring information, user control information, and service control information of each network slice in at least one network slice obtained from the data analysis to summarize the information of each network slice in at least one network slice. The first message.

It should be noted that, on the one hand, the first request may carry filtering information, so that the data analysis network element obtains the first information used to determine the slice quality information according to the first request. The network element determined by the slice management control network element determines the relationship between the slice quality of the network slice and the quality requirement of the network slice based on the first information. Alternatively, the first request may also carry demand information, so that after determining the slice quality information, the data analysis network element may determine the first indication information according to the slice quality information of any network slice and the demand information corresponding to the network slice . For example, the data analysis network element determines the slice quality according to the slice quality information, and then determines the quality requirements of the network slice according to the demand information corresponding to the network slice, thereby sending the determined first indication information to the data analysis network element.

In summary, if the first request can also carry demand information, then the first information can be the first indication information. If the first request does not carry demand information, the first information may be slice quality information.

Specifically, for the specific content of the first information, reference may be made to the description at step 101 above, and details are not described herein again.

Step 107: The data analysis network element sends a first response to the slice management control network element, where the first response includes first information corresponding to at least one network slice.

It should be understood that the first response includes identification information of at least one network slice, and first information corresponding to each network slice in the at least one network slice.

Step 108: The slice management control network element receives the first response sent by the data analysis network element.

After receiving the first response, the slice management control network element may also send information indicating that the first response is received to the data analysis network element.

Correspondingly, step 101 may specifically be implemented in the following manner: the slice management control network element obtains the first information corresponding to each network slice in the at least one network slice according to the first response.

The above embodiment mainly describes the process of controlling user access in the first network slice by the slice management control network element. In an actual process, if at least one network slice has a first indication of other network slices than the first network slice If the information does not meet the quality requirements of other network slices, the slice management control network element can also control user access in other network slices. Exemplarily, in some embodiments, as shown in FIG. 6, the method provided in the embodiments of the present application further includes:

Step 109: The slice management control network element controls user access in other network slices in the at least one network slice except the first network slice according to the first indication information of the at least one network slice. In this step, the main consideration is to introduce a new network slice or an unsigned slice SLA slice, which may affect the quality of the existing network slice. If it does, it also needs to be connected to the user of the affected network slice. Control.

It should be understood that, for the specific implementation of step 109, reference may be made to the specific implementation of step 103, and details are not described herein again.

The above mainly describes the process of the slice management control network element controlling user access in the network slice according to the quality information of the network slice. In some embodiments, the slice management control network element may also notify the access network device corresponding to the network slice to adjust the Air interface resources for network slicing. As shown in FIG. 7, the method provided in this embodiment of the present application further includes:

Step 110: The slice management control network element sends first indication information of at least one network slice to at least one access network device serving at least one network slice.

In Example 1, step 110 may be implemented as follows: the slice management control network element may send the first indication information of the first network slice to at least one first access network device serving the first network slice. The first indication information of at least one network slice may also be sent to at least one first access network device serving the first network slice.

Because one slice management control network element can manage multiple access and mobility management function network elements, and the access network equipment accesses the core network through the access and mobility management function network element, one access and mobility management function The network element can manage multiple access network devices. An access and mobility management function network element usually includes multiple tracking areas (Tracking Areas, TAs), and multiple AMFs and multiple RANs can be supported within the area indicated by the area information. And usually the number of AMF is less than the number of RAN.

Therefore, the slice management control network element can address multiple access and mobility management function network elements supporting S-NSSAI slice under the TA through TA / S-NSSAI. The access and mobility management function network element can address multiple access network devices supporting S-NSSAI slice under the TA through TA / S-NSSAI.

Exemplarily, the method provided by the embodiment of the present application further includes: the slice management control network element determines the address or identification information of at least one access and mobility management function network element through the area information corresponding to any first network slice.

The address or identification information of at least one access and mobility management function network element is used to identify at least one access and mobility management function network element.

For example, the slice management control network element may send the first indication information of the first network slice to the at least one first access network device through at least one access and mobility management function network element, where the at least one first The network element of the access and mobility management function serves the first network slice.

Exemplarily, the first network slice NS1 corresponds to RAN1 and RAN2, and NS2 corresponds to RAN3, then the slice management control network element sends the first indication information of NS1 to RAN1 and RAN2. Or the slice management control network element sends the first indication information of NS1 and NS2 to RAN1 and RAN2.

In Example 2, step 110 may be implemented as follows: the slice management control network element may send first indication information of other network slices to at least one second access network device serving other network slices. The first indication information of the at least one network slice may also be sent to at least one second access network device serving other network slices.

It should be understood that at least one second access network device in Example 2 includes at least one second access network device corresponding to all other network slices in other network slices.

For example, the slice management control network element may send first indication information of other network slices to at least one second access network device through at least one access and mobility management function network element, wherein the at least one access and mobility The management function network element serves other network slices.

It should be understood that the access network devices corresponding to different network slices may be the same. For example, the first network slices NS1 and NS2 both correspond to RAN1, but NS2 may also correspond to RAN2.

Specifically, the slice management control network element may execute any one of the above example 1 and example 2.

No matter which network slice the first indication information the access network device receives, it can process the air interface resource scheduled for the network slice for the access network device, because the access network device according to the first indication of any network slice The information processing is the same for the air interface resources scheduled by any network slice. Therefore, in the embodiment of the present application, the second network slice is used as an example. The second network slice is any network slice in at least one network slice, and does not have any Indicative meaning:

As shown in FIG. 7, the method provided in this embodiment of the present application further includes:

Step 111: At least one access network device receives first indication information of at least one network slice.

Exemplarily, at least one access network device may obtain the first indication information of the network slice from a slice management control network element.

Exemplarily, step 111 may be specifically implemented in the following manner: The RAN obtains the first indication information of the network slice through at least one access and mobility management function network element or a network management network element.

Step 112: At least one access network device processes the air interface resources scheduled for the second network slice according to the first indication information of the second network slice.

Since one network slice may correspond to multiple access network devices, the at least one access network device may negotiate which access network device processes the air interface resources scheduled for the second network slice. Or at least one access network device jointly processes air interface resources scheduled for the second network slice.

Specifically, step 112 may be implemented in the following manner: when the slice quality of the second network slice is higher than the quality requirement of the second network slice, the RAN reduces the air interface resources scheduled for the second network slice. When the slice quality of the second network slice is lower than the quality requirement of the second network slice, the RAN increases the air interface resources scheduled for the second network slice. When the quality of the second network slice is equal to the quality requirement of the second network slice, the RAN maintains the air interface resources scheduled for the second network slice.

In some embodiments, the slice management control network element may also send the area information, time information, and average service experience of at least one service of any network slice to at least one access network device of any network slice. At this time, at least one access network device can also obtain area information, time information, and average service experience of at least one service of any network slice. After receiving this information, the access network device can more accurately control the air interface resources of the network slice. For example, air interface resource scheduling can be arranged based on area information and time information.

It should be noted that in one aspect of the embodiments of the present application, the slice management control network element may perform step 103 and perform step 110, that is, when the slice management control network element controls user access in the first network slice, the first The first indication information of the network slice is sent to the access network device. On the other hand, the slice management control network element may use step 110 instead of step 103. In this case, the slice management control network element may not perform the process of controlling user access in the first network slice, and only the access network device adjusts the air interface resource according to the first indication information.

Steps 110-112 mainly describe the process in which the RAN decides how to adjust the air interface resources of the network slice according to the first indication information of the network slice. In the actual process, the access network device can also adjust the network slice according to the instructions of the slice management control network element Air resources. The specific process is as follows:

It should be understood that, after determining the first indication information of any network slice in the embodiment of the present application, the slice management control network element may first determine whether the air interface resources allocated by the access network device for the any network slice are sufficient The network device indicates whether it is necessary to reduce the air interface resources allocated to the network slice, to increase the air interface resources allocated to the network slice, or to maintain the air interface resources allocated to the network slice unchanged.

Exemplarily, if the access network device allocates sufficient air interface resources for any one network slice, the slice management control network element sends a first instruction to the access network device to indicate that the allocation for the any one network slice is reduced Air resources. If the access network device allocates insufficient air interface resources for any one network slice, the slice management control network element sends a second indication to the access network device for instructing to increase the air interface resources allocated for any one network slice. If the air interface resources allocated by the access network device for the any network slice are moderate, the slice management control network element sends a third indication to the access network device for instructing to maintain the air interface resources allocated for the any network slice.

Exemplarily, when the network slice is in an excess state, that is, when the slice quality of the network slice is greater than the quality requirement, the first indication is sent to the access network device. Specifically, when the slice quality of the network slice is greater than the quality requirement, and the maximum number of users joining the network slice meets the tenant requirements, the first indication may be sent. In this way, the access network device may reduce the air interface resources allocated to any one network slice according to the first instruction.

Exemplarily, when the network slice is in the SLA underfitting state, that is, when the slice quality of the network slice is less than the quality requirement, the second indication is sent to the access network device. Specifically, when the slice quality of the network slice is less than the quality requirement, and the maximum number of users joining the network slice does not meet the tenant requirements, the second indication may be sent. In this way, the access network device may increase the air interface resources allocated to any one network slice according to the second instruction.

Exemplarily, when the slice quality of the network slice is equal to the quality requirement, a third indication is sent to the access network device. Specifically, the third indication may be sent when the slice quality of the network slice is equal to the quality requirement, and the maximum number of users joining the network slice is equal to the tenant requirement. In this way, the access network device may maintain the air interface resource allocated by the any network slice unchanged according to the third instruction.

FIG. 8 is a specific example of network slice quality information provided by an embodiment of the present application. In this solution, the data analysis network element is NWDAF network element, the access network device is RAN, and the slice management control network element is NSSF network element. For example. Specifically, as shown in FIG. 8, the method includes:

Step 201: The NSSF network element determines that the first network slice is a newly created network slice or a network slice that has not signed an SLA.

Specifically, the NSSF network element may determine that the first network slice is newly created in the following manner. For example, during the creation of the first network slice by OAM, the first indication information is sent to the NSSF network element, and the first indication information is used to indicate that the first network slice is newly established, so that the NSSF network element can determine the first A network slice is newly created. Alternatively, the operator may directly configure the first network slice as a newly created network slice or a network slice without an SLA on an NSSF network element.

Step 202: The NSSF network element obtains demand information.

Specifically, for the content of the demand information, reference may be made to the description in the foregoing embodiment, and details are not described herein again.

Step 203: The NSSF network element subscribes to statistical information of at least one network slice from NWDAF through a subscription event request (for example, Nnwdaf_EventSubscription_Subscribe).

Exemplarily, Nnwdaf_EventSubscription_Subscribe may be the first request in the foregoing embodiment. The slice statistical information may be the first information of the network slice in the above embodiment.

Exemplarily, Nnwdaf_EventSubscription_Subscribe can carry S-NSSAIs, Tracking Area, Time Window.

S-NSSAIs represent the identification information of at least one network slice. The at least one network slice includes the identification information of the first network slice and the identification information of the existing network slice.

Tracking Area is area information, which can be TA or TA list / Cell list.

The existing network slice can be the network slice that has signed the Slice SLA.

It can be understood that step 203 is used by the NSSF network element to request the NWDAF network element for statistical information of at least one network slice of an area within a time period.

Step 204: The NWDAF network element analyzes and obtains the statistical information of at least one network slice, and feeds back the statistical information of at least one network slice in the area within the time period requested by the NSSF to the NSSF network element through a subscription event notification (Nnwdaf_EventSubscription_Notify) service operation.

Exemplarily, the Nnwdaf_EventSubscription_Notify service operation may be the first response in the foregoing embodiment.

Exemplarily, the statistical information includes: time period, area information, statistical information of at least one network slice, identification information of the network slice, the first maximum number of registered users (for example, 1 million), and a service for each service of a network slice At least one of the information.

The service information is used to indicate that the current network can satisfy the state of the service in the network slice. For example, the service information includes: service identifier, first maximum number of users (that is, the maximum number of users that can be satisfied in the service in the current network), first average service experience (Average Service), and first service satisfaction.

Step 205: The NSSF network element determines the first indication information (estimated) of each network slice in the corresponding area in the time period according to the statistical information and / or the pre-configuration policy of at least one network slice in an area from the NWDAF slice quality), the first indication information is used to indicate the relationship between the slice quality of the network slice satisfied by the current network and the quality requirement of the network slice.

Step 206: The NSSF network element determines the state of the first network slice according to the first indication information of at least one network slice.

Step 207: If the NSSF network element determines that the first network slice is in the state of Slice, SLA, and overfitting, and the second maximum number of registered users required by the current tenant cannot be added to the first network slice, the NSSF network element may allow more users Access the first network slice.

For example, if the NSSF network element estimates the slice quality of the first network slice to be 120%, the tenant requires that the number of users in the first network slice is 10 million, but the first network slice is currently The number of accessed users is 1 million (1 million). It shows that the RAN has allocated excess air interface resources for the first network slice, and can also allow more users to access the first network slice.

Step 208. If the NSSF network element determines that the first network slice is in the Slice, SLA, and overfitting state, and finds that the second maximum number of registered users required by the current tenant has been added to the first network slice, the NSSF network element can use the AMF network element to At least one RAN corresponding to the first network slice sends a first indication, where the first indication is used to indicate reduction of air interface resources allocated to the first network slice.

Step 209: At least one RAN receives the first indication, and reduces the air interface resources allocated for the first network slice according to the first indication.

Step 210: If the NSSF network element determines that the first network slice is in Slice, SLA, and underfitting, and the second maximum number of registered users required by the current tenant is not all added to the first network slice, the RAN allocates insufficient resources for the slice. At least one access network device corresponding to the first network slice sends a second indication, and the second indication increases the air interface resources allocated for the first network slice.

Step 211: At least one RAN receives the second indication, and increases the air interface resources allocated for the first network slice according to the second indication.

Step 212: If the NSSF network element determines that the slice quality and quality requirements of the first network slice are equal, and the second maximum number of registered users required by the current tenant are all added to the first network slice, then at least correspond to the first network slice. An access network device sends a third indication, which is used to indicate that the air interface resource allocated for the first network slice remains unchanged.

Step 213: At least one RAN receives the third indication, and maintains the air interface resources allocated for the first network slice unchanged according to the second indication.

The difference between FIG. 9 and FIG. 8 is that, in FIG. 9, after the NSSF network element performs steps 201-step 205, steps 206'-step 211 'are used instead of steps 206-step 213 in FIG.

Step 206 ': The NSSF network element sends an NSSAI availability notification message (for example, Nnssf_NSSAIAvailability_Notify) to at least one AMF network element, where Nnssf_NSSAIAvailability_Notify carries first indication information of the first network slice.

It should be understood that the area covered by the at least one AMF network element includes the area where the first network slice is located.

Step 207 ': At least one AMF network element sends a configuration update message (CONFIGURATION UPDATE message) to at least one RAN serving the first network slice, and the CONFIGURATION UPDATE message carries the first indication information of the first network slice.

It should be understood that at least one RAN in step 207 'belongs to the area where the first network slice is located.

Step 208 '. At least one RAN receives the first indication information of the first network slice through at least one access and mobility management function network element.

Exemplarily, the at least one RAN may obtain the first indication information of the first network slice from the CONFIGURATION UPDATE message sent by the access and mobility management function network element.

Step 209 '. If the slice quality of the first network slice is higher than the quality requirement of the first network slice, at least one RAN reduces the air interface resources scheduled for the first network slice.

Step 210 '. If the slice quality of the first network slice is lower than if the quality requirement of the first network slice, at least one RAN increases the air interface resources scheduled for the first network slice.

Step 211 ': If the quality of the first network slice is equal to if the quality of the first network slice is required, at least one RAN maintains the air interface resource scheduled for the network slice.
