FIG. 1 is a schematic representation of a service-based network architecture according to an embodiment of this application. As shown in FIG. 1, the network architecture shown in FIG. 1 may include three parts: a terminal device that is part, an operator network that is part, and a data network (DN). The functions of some network elements are briefly described below.

An operator network may include one or more of the following network elements: a network exposure function (NEF) network element, a Network Repository Function (NRF) network element, a policy control function (PCF) network element ), a unified data management (UDM) network element, a network data analytics function (NWDAF) network element, an application function (AF) network element, a mobility and access control network element ( access and mobility management function (AMF), session management function (SMF) network element, radio access network (RAN), unified data repository (UDR) (which is not shown in the figure), user plane function (UPF) network element, and the like. In the above operator network, parts other than the radio access network may be referred to as core network parts.

A terminal device, which may also be referred to as user equipment (UE), is a device that has the function of a wireless transceiver. The terminal device may be deployed on land, and the deployment includes indoor or outdoor deployment, manual or vehicle-mounted deployment; can be deployed on the surface of the water (for example, on a ship); or may be deployed in the air (eg by aircraft, balloon or satellite). The terminal device can be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless reception and transmission function, a virtual reality terminal (virtual reality, VR), an augmented reality terminal (augmented reality, AR), a wireless terminal in industrial control (industrial control), wireless terminal in self driving, wireless terminal in telemedicine (remote medical), wireless terminal in smart grid (smart grid), wireless terminal in transportation safety, wireless terminal in smart city ( smart city), a wireless terminal in a smart home (smart home) and the like. For ease of description in this application, the UE is subsequently used to replace the terminal device for description.

The terminal device may connect to the operator's network through an interface (eg, N1) provided by the operator's network and use services such as data service and/or voice service provided by the operator's network. The terminal device may further access the DN through the operator's network and use the operator's service deployed in the DN and/or a service provided by a third party. The third party may be a service provider other than the operator's network and the terminal device and may provide services such as data service and/or voice service for the terminal device. The specific form of representation of the third party in particular may be determined based on the actual application scenario, and is not limited herein.

The RAN is a subnetwork of the operator's network and is the implementation system between the service node in the operator's network and the terminal device. To access the operator's network, the terminal device first passes through the RAN and can be connected to the service node of the operator's network via the RAN. The RAN device in this application is a device that provides a wireless communication function for a terminal device, and the RAN device is also referred to as an access network device. The RAN device in this application includes, but is not limited to: Next Generation NodeB (gNodeB, gNB) in 5G, evolved NodeB (eNB), radio network controller (RNC), Node B (NodeB, NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home enhanced node B or home NodeB, HNB), baseband unit (baseband unit, BBU ), a receiving/transmitting point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a mobile switching center, and the like.

The AMF network element, which is also referred to as the mobility management function, is responsible for user mobility management, including mobility status management, allocation of temporary user identities, and user authentication and authorization.

The SMF, also referred to as the session management function, is responsible for UPF selection, UPF reselection, IP address allocation, bearer establishment, modification and release, and QoS management.

The UPF network element supports all or some of the following functions: interconnecting a protocol data unit (PDU) session with a data network; packet routing and forwarding (eg, support for forwarding traffic to a data network after performing uplink classification, and support for a branch point to support a multi-connection PDU session); and package detection.

DN is a network outside the operator's network. The operator's network can access multiple DNs. A plurality of services (services) may be deployed in a DN, and a DN may provide services such as a data service and/or a voice service for a terminal device. For example, a DN is a smart factory private network, a sensor installed in a smart factory workshop may be a terminal device, a control server for said sensor is deployed in the DN, and this control server may provide a service for said sensor. The sensor may communicate with the control server to receive instructions from the control server, transmit collected sensor data to the control server as instructed, and the like. In another example, the DN is the company's internal office network, the employee's mobile phone or computer may be a terminal device, and the employee's mobile phone or computer can access information, data resources, and the like on the company's internal office network.

The UDM network element is responsible for managing the subscription data and is responsible for notifying the appropriate network element when the subscription data is modified.

The UDR is configured to store and retrieve subscription data, policy data, and general architecture data, and is used by the UDM, PCF, and NEF to obtain associated data. The UDR must provide different data access authentication mechanisms for different types of data, such as subscription data and policy data, to ensure data access is secure. The UDR shall return an error response with an appropriate reason value for an invalid operation based on a service or data access request.

The NEF network element is primarily configured to support exposure of events and opportunities.

The AF network element provides an application layer service to the UE. When providing a service to a UE, the AF makes demands on the QoS policy and charging policy (Charging), and notifies the network. In addition, AF also requires the core network to feed back application related information.

The PCF network element performs policy decision and flow-based billing control functions, and these functions include a user subscription data management function, a policy management function, a billing policy management function, QoS control, and the like.

The NRF network element may be configured to provide a network element discovery function and provide network element information corresponding to the network element type based on a request from another network element. The NRF further provides a NE management service, such as NE registration, renewal, and deregistration, and NE status subscription and push.

The NWDAF network element may be configured to collect, train and analyze the data and deliver the result of the analytical processing to another functional network element to help that other functional network element to optimize the corresponding policy control. For example, NWDAF provides terminal device mobility analytic information to AMF to assist AMF in formulating mobility related policy, or NWDAF provides terminal device session analytic information to SMF to assist SMF in formulating session management related policy.

With regard to the description of the functions of the network elements in FIG. 2, refer to the description of the functions of the respective network elements in FIG. 1. Details are not repeated. The main difference between FIG. 2 and FIG. 1 is that the interface between network elements in FIG. 2 is a point-to-point interface, not a service-based interface. It should be noted that FIG. 2 further includes other network elements such as NEF network element, NRF network element, NWDAF network element, and UDR, which in FIG. 2 are not shown.

It can be understood that network elements or functions may be network elements in a hardware device, may be software functions running on dedicated hardware, or may be virtualized functions instantiated on a platform (eg, a cloud platform). Optionally, the network elements or functions may be implemented by a single device, or may be jointly implemented by multiple devices, or may be a single functional unit in a single device. In the embodiments of the present application, this is not specifically limited.

This application is not limited. For ease of description, that a Mobility Management Network Element, a Session Management Network Element, a Policy Network Element, an Application Functions Network Element, an Access Network Device, a Network Exposure Function Network Element, and a User Plane Network Element are, respectively, AMF, SMF, PCF, AF, RAN, NEF and UPF is used as an example for description in this application. In addition, this application uses an example in which the terminal device is a UE for description.

The network element of analytical data processing in this application may be a network element that has the functions of inference, analysis, training, data collection; and may collect related data from the network function network element, third-party service server, terminal device, or network management system, perform analysis and training based on the related data, and provide data analysis information to the network function network element, third-party service server, terminal device, or system network administration. For example, a data analytics network element may be an NWDAF or a management data analytics service (MDAS). The analytics network element may be an independent network element, may be a combination of multiple network elements, or may be integrated with another network element.

The network in the present invention may be any type of PLMN, a private network, a network segment, a segment instance, or a segment subnetwork instance. For ease of description, the present invention does not explicitly reflect that the training data collected by the analytics network element and the analytics information generated by the analytics network element include network ID information. For example, for a network segment, the training data actually collected by the analytics network element or the analytics information generated by the analytics network element may include segment identifier information such as network slice selection assistance information, NSSAI), single network slice selection assistance information (S-NSSAI), network slice instance identifier (NSI), and network slice subnet instance identifier (NSSI).

All analytical information described in the present invention may be statistical information or prediction information. For example, the service experience insights may be service experience statistics or service experience prediction information, and the service related performance insights may be service performance statistics or service performance prediction information.

FIG. 3 is a schematic representation of a 5G dual connectivity network architecture according to an embodiment of this application. FIG. 4 is a schematic representation of an interoperability architecture between a single connection 5G network and a single connection 4G network according to an embodiment of the present application.

In the network architecture shown in FIG. 3, the terminal device can access the 5G network using the NR or LTE standard, but the core networks corresponding to the terminal device are the same 5GC core networks. However, in the network architecture shown in FIG. 4, the terminal device can access a 4G network using LTE technology and access a 5G network using NR technology, and the core networks corresponding to the terminal device are EPC core networks and 5GC core networks, which are independent of each other.

With regard to the architecture in FIG. 3, in the 5G network, there is a network deployment scenario in which access networks of two types of radio access (radio access type, RAT) coexist: enhanced long-term evolution (eLTE) and new radio communication (new radio, NR), and can be a plurality of access frequencies (eg, 2.6 GHz, 3.5 GHz, 700 MHz, and 900 MHz) for each RAT.

With regard to the architecture in FIG. 4, before the full transition from 4G network, there is a scenario of interaction between the terminal device in 5G network and 4G network, RAT in 5G network and 4G network may be different, and there may be multiple access frequencies for each RAT.

For the above two scenarios, the following problems may exist: (1) Different services should be provided using different RATs or access frequencies (frequencies) in order to achieve a better service effect. For example, voice service in eLTE/LTE network is more stable, and cloud AR/VR is more sensitive to data rate and latency, so cloud AR/VR needs to run in NR. (2) Allocation of RAT or access frequency can be performed for users and services of different value. For example, NR has high cost and good quality, and is predominantly for high value users and services. (3) For the purposes of network load balancing, power saving, and the like, the RAT allocation scheme or access frequency should change dynamically and adaptively depending on time and place. For example, when the NR load is low, some low value services may be serviced. On the other hand, when low value services are migrated to eLTE/LTE or RAT or access frequency must/should be turned off/off due to low cell usage within the time slot, the existing user must be transferred to another RAT or another access frequency .

This application provides a way to define a policy. The data analytic processing network element generates analytic information based on the received network data and service data, and provides the analytic information to the network function network element. The network function network element allocates dynamically changing RATs or access rates to the terminal device based on the analytic information to satisfy the requirement for the service experience of the terminal device. In this embodiment of this application, the NWDAF may be replaced by any other network element or functional module that has data analytics capability. The network function network element may be a core network element, an access network element, a terminal device, an application server, a network administration network element, or the like. In this document, this is not a limitation.

FIG. 5 is a schematic flow diagram of a policy determination method according to an embodiment of this application.

S201: The first network element receives the first analytic information from the analytic processing network element, the first analytic information including at least one of the following information: RAT related information or access frequency related information and experience analytic information service corresponding to the RAT or frequency of access.

It should be understood that the first network element may be a network element that has a decision function and may provide various related policies to the network device or terminal device. For example, the first network element may be PCF, AMF, or RAN. The first network element in this embodiment is specifically related to deciding on the radio access information policy. The analytical data processing network element may be a network element that has the functions of inference, analysis, training, and data collection; and may collect related data from the network function network element, third-party service server, terminal device, or network management system, perform analysis and learning based on the related data, and provide data analysis information to the network function network element, third-party service server, terminal device, or system network administration. For example, an analytic data processing network element may be NWDAF, MDAS, or the like. The analytics network element may be an independent network element, may be a combination of multiple network elements, or may be integrated with a first network element or another network element.

Optionally, the RAT related information or access frequency related information includes at least one of the following information: identifier, service type, recommended RAT or recommended access frequency, time information, and terminal device area information. The RAT related information or the access frequency related information may be a recommended RAT or a recommended access frequency for at least one terminal device. For example, for a particular terminal device, eLTE or 700 MHz may be recommended for access. Alternatively, the RAT related information or access frequency related information may be a recommended RAT or a recommended access frequency for at least one type of service. For example, for voice service eLTE or 700 MHz may be recommended for access. Alternatively, the RAT related information or access frequency related information may be a recommended RAT or a recommended access frequency for at least one service type of at least one terminal device. For example, for an AR/VR service that is performed by a terminal device, NR or 3.5 GHz may be recommended for access; and for a voice service that is performed by a terminal device, eLTE or 700 MHz may be recommended for access. In addition, information related to the RAT, or information related to the access frequency, may dynamically change depending on time, location, or other factors. For example, when a terminal device uses a metro voice service or uses a square voice service, other RATs or frequencies are recommended. This can be configured specifically based on the actual requirement.

It should be understood that the service type or service type of the terminal device in this application may be only one or more service types.

Optionally, the service experience analytic information corresponding to the RAT or access frequency includes at least one of the following information: identifier, service type, RAT or access frequency, service experience for the service type, time information, and terminal device area information. . The service experience analytic information corresponding to the RAT or access frequency may be used to indicate the service experience corresponding to at least one service type in the RAT or access frequency. For example, the Mean Opinion Score (MOS) of NR/3.5 GHz voice service is 3 and the LTE/700 MHz voice MOS is 4.5. The service experience analytic information corresponding to the RAT or access frequency may be further used to indicate the service experience corresponding to at least one service type of at least one terminal device in the RAT or access frequency. For example, the Mean Opinion Score (MOS) of a particular device voice service at NR/3.5 GHz is 3.5, and the MOS of a terminal device voice service at LTE/700 MHz is 4.

In the present invention, the service experience is represented by MOS or other parameters such as latency, smoothness, throughput, packet loss ratio, jitter, or traffic. Alternatively, the service experience may be represented by a combination of a plurality of experience parameters, such as experience for a combination of delay and smoothness. In this document, this is not a limitation. Optionally, the first network element may be a core network element, a network administration network element, an application server, or the like. The core network element includes a control plane network element or a user plane network element.

Optionally, the first network element may be an access network element, such as a RAN. The access network element may directly obtain the first analytic information provided by the analytic processing network element and perform an appropriate RAT or frequency selection operation for the terminal device based on the first analytic information. For example, after the access network element selects the proper target RAT or the proper target access rate for the terminal device based on the first analytic information, if the terminal is in connected mode, the access network element can perform a handover, through a handover procedure, of the terminal device in a target cell corresponding to the target RAT or target access frequency. Alternatively, the access network element may send the associated target RAT or associated target access frequency to the terminal device via a redirection procedure such that upon entering the idle mode, the terminal device may choose to access the cell corresponding to the target RAT or target access frequency. In another example, after the access network element selects a proper target RAT or a proper target access rate for the terminal device based on the first analytic information, if the terminal is currently in the idle mode, the access network element may wait until the terminal the device will not enter connected mode. Alternatively, after the access network calls the terminal device to connected mode, the access network then allows the terminal device, using a redirection or connected mode handoff method, to access a cell corresponding to the target RAT or target access frequency.

Optionally, the first network element may be a terminal device. The terminal device directly receives the first analytic information provided by the analytic data processing network element and accesses the associated RAT or the associated frequency with reference to the first analytic information. For example, the terminal device selects a proper target RAT or a proper target access frequency based on the first analytic information, and the terminal device can access by network reselection or cell reselection to a cell corresponding to the target RAT or target access frequency.

S202: The first network element determines the access information selection policy of the terminal device based on the first analytic information, the access information selection policy includes a target RAT or a target access frequency corresponding to the terminal device.

Optionally, the first network element determines, based on the first analytic information, the target RAT or target access frequency corresponding to the terminal device, so that the service experience for the service type of the terminal device at the target RAT or target access frequency can satisfy a predetermined condition. The terminal device service type may include one or more terminal device service types.

In a possible implementation, when the first analytic information is RAT related information or access frequency related information, and this access frequency or RAT information includes a recommended RAT or recommended access frequency for the terminal device, the method in which the first network element determines the access information selection policy of the terminal device based on the first analytic information, includes: The first network element determines the recommended RAT or the recommended access frequency for the terminal device as the target RAT or the target access frequency corresponding to the terminal device. As shown in Table 1 below, the first analytic information includes the recommended RAT or recommended frequency for terminal device A, terminal device B, and terminal device C. In this case, the first network element determines the recommended RAT or recommended eLTE/900 MHz frequency for the terminal device. device A as the target RAT or target access frequency of terminal device A. When using eLTE/900 MHz, the service experience of terminal device A can satisfy a given condition (eg, be optimal).

As shown in Table 3 below as an example, the first analysis information includes recommended RATs or recommended frequencies for service A of terminal device A, service B of terminal device A, service A of terminal device B, and service C of terminal device B. If the first network element specifies service A that has been initiated or is to be initiated by terminal device A, the first network element specifies the recommended RAT or recommended NR/2.6 GHz frequency for service A of terminal device A as the target RAT or target access frequency of terminal device A.

Optionally, the terminal device ID in Table 7 is the ID of the terminal device being parsed. In an exemplary implementation, the terminal device identifier is used to identify one non-specific terminal device, i. the data analysis network element receives the data shown in Table 7 for a large number of terminal devices. Based on this analysis, the first analytical information that is not specific to the terminal device is generated. In yet another possible implementation, the terminal device identifier is used to identify one non-specific terminal device, i.e. the analytic processing network element obtains the information specified in Table 7 only for a particular terminal device in order to analyze the first analytic information of that terminal device. It should be understood that Table 7 is only an example. The type of data received is not limited in this application, and each type of data listed in Table 7 need not be mandatory. For example, the NWDAF may not need to be collected from a network element such as AMF, RAT, or the frequency on which the terminal device is located, but obtain the cell identifier of the terminal device from the AMF. If the NWDAF configures the RAT or frequency corresponding to the cell ID, the NWDAF can also obtain RAT or frequency based service experience analytics.

The next step 303 is described using an example in which the first analytic information is a service experience analytic information corresponding to a RAT or an access frequency.

It should be understood that how an analytics network element obtains, based on the input training data, service experience analytics corresponding to an output RAT or an output access frequency is not limited here, and the method used may be one such as collection of statistical information based on big data, forecasting or the like.

S304: The data analytics network element analyzes and obtains analytic information about the service-related operation of the terminal device based on the received data.

The analytic information about the service-related operation of the terminal device refers to the analytical processing information, which may reflect the situation or rule of using the service by the terminal device.

Optionally, the service-related performance analysis information includes at least one of the following information: identifier, time information, area information, service type, service type priority information, service type occurrence probability, and service type duration for terminal device.

In an exemplary implementation, analytic information about the service-related operation of the terminal device that is parsed and obtained by the data analytics network element can be shown in Table 9.

Table 9

It should be understood that the content of the analytical information in Table 9 is only an example, and each piece of information is not necessarily mandatory.

Optionally, the analysis information about the service-related operation of the terminal device includes statistical information about the service-related operation of the terminal device or prediction information about the service-related operation of the terminal device. In other words, the content (eg, service occurrence probability) included in the analytic information about the service-related operation of the terminal device may be used as statistical information or may be used as prediction information.

How the analytics network element obtains, based on the input data, the output analytics information about the service-related operation of the terminal device is not limited here, and the method used may be a method such as collecting statistical information based on big data, forecasting or the like.

For example, when the terminal device service-related operation prediction information is terminal device service-related operation prediction information, the analytic processing network element needs to determine the service-related operation prediction information of one terminal device.

Optionally, the analytics network element may analyze the analytics information about the service-related operation of the terminal device in a predictive manner. For example, the analytics network element determines the classification information of the user profile identity to which the terminal device belongs, and the analytics network element predicts the service-related operation of this terminal device based on said classification information of the user profile identity to which the terminal device belongs, and historical information about the service-related operation of the terminal device of the same type of personality profile to determine insights about the service-related operation of the terminal device.

Optionally, the analytics network element collects terminal device level network related operation data, terminal device level service related operation data, and terminal device level service attribute data, the analytics network element determines a user profile personality classification model based on the terminal device level network-related operation data, terminal device level service-related operation data, and terminal device-level service attribute data, and the data analysis network element determines, based on the classification model of the user profile identity, and network-related operation data, data about the service-related operation and service attribute data of the terminal device to be analyzed, the classification information of the user profile identity to which the terminal device to be analyzed belongs.

It should be understood that the analytics network element may determine the service-related operation of the terminal device to be analyzed based on another terminal device whose user profile personality classification is similar to that of said terminal device to be analyzed. That is, if the service-related operation of another terminal device is exactly the same or similar to that of the terminal device under analysis, for example, if similar service-related operation was performed at some time or in some places in the past, the service-related operation of the terminal device under analysis of the terminal device can be predicted based on the service-related operation performed by another terminal device at the current time or at the current location.

It should be noted that steps 302 to 304 are independent of step 301, and there is no time sequence between steps 302 to 304 and step 301. In other words, the data analytics network element can receive the associated training data in advance and generate the associated analytics, and it is not necessary to perform the associated operation only after receiving the first request message.

S305: The analytic processing network element sends a first response message to the first network element, the first response message including the first analytic information.

The first analysis information is an analysis message corresponding to the first request message in step S301.

Optionally, the first response message further includes analytic information about the service-related operation of the terminal device.

It should be understood that service-related terminal device performance information may not be included in the first response message, or may be sent separately.

Optionally, service experience insights and service related performance insights can dynamically change depending on the scenario. In other words, the service experience insights and the service related performance insights may be sent at one time or may be sent multiple times.

Optionally, the analytics processing network element may separately send the applicable analytics condition to the first network element, that is, the applicable analytics condition is not included in the service experience insight or service related performance insight, but may be included in the first response message. to send; or may be sent separately and not included in the first response message.

S306: The first network element obtains the first analytic information and determines the access information selection policy of the terminal device.

The access information selection policy of the terminal device is used to indicate a corresponding target RAT or a corresponding target access frequency that/which the terminal device needs to access in a scenario (time, place, or the like).

In a possible implementation, the access information selection policy defined by the first network element can be represented as the first network element generating a dynamically changing frequency selection priority (RAT/frequency selection priority, RFSP) / subscriber profile ID for the frequency selection priority/RAT (subscriber profile ID for RAT/frequency priority, SPID) for the terminal device. RFSP/SPID is used to indicate the priority of access frequency selection or RAT. For example, in some scenario (time or place), if the RFSP/SPID indicates that the NR selection priority is the highest, it indicates that in this case, the terminal device needs to select NR for binding. In another scenario, if the RFSP/SPID indicates that the Evolved Access Network (E-UTRAN) selection priority is the highest, in this case, the terminal device needs to select the E-UTRAN for binding.

It should be understood that, in addition to the RFSP/SPID technique, the access information selection policy may be represented by other techniques, provided that the access network element can assist the access network element in selecting a target RAT or target access rate for a terminal device, or the terminal device selects a target RAT or target access rate.

Optionally, the first network element may determine the access information selection policy of the terminal device in two steps.

Step 1: The first network element determines, based on service-related operation intelligence of the terminal device, the type of service to be used by the terminal device in the scenario (time, place, or terminal device).

For example, the selected service type is typically the service type that is most likely to be used by the terminal device in the current scenario, or the selected service type may be the service type that the terminal device uses the longest in the current scenario, or the selected service type is the service type with the highest priority for the terminal device in the current scenario.

Step 2: Based on the type of service obtained in step 1, the first network element determines the target RAT or target access rate based on the first analytic information. The service experience of the terminal device can satisfy a given condition when using the target RAT or the target access frequency. For example, the MOS of voice service of a terminal device may exceed 3 points when using eLTE/700 MHz. In this case, eLTE/700 MHz is used as the target RAT or target access frequency corresponding to the terminal device when the terminal device initiates a voice service. In another example, it is recommended by NWDAF that the voice service of the terminal device access eLTE/700 MHz. In this case, eLTE/700 MHz is used as the target RAT or target access frequency corresponding to the terminal device when the terminal device initiates a voice service.

Optionally, in addition to the above two types of data analysis information, the first network element may further determine the access information selection policy of the terminal device considering the first information. The first information may include, but is not limited to, at least one of the following information:

service priority information, such as high priority, low priority, or priority value;

information about the pricing policy of the service, for example, high, medium or low tariff, or tariff value;

a user type of the terminal device, wherein the user type may be level information, such as a gold user, a silver user, or a bronze user, and the user type may also indicate user classification information, such as an office worker user or a student user;

analysis information about the mobility mode of the terminal device, such as information tracking the movement of the terminal device, and whether the terminal device is a fixed physical network terminal device;

analytic information about the communication mode of the terminal device, such as a communication behavioral model of the terminal device; And

RAT traffic or load information or access frequencies, for example RAT NR cell is heavily loaded and eLTE cell is lightly loaded.

Optionally, the first information may be configured in a network, such as a first network element, or may be obtained from another network element, such as an AMF, a billing system, or an analytics network element.

For example, the first network element determines, based on insights about the service-related operation of the terminal device, that the probabilities of occurrence of two types of services of the terminal device are equivalent in some scenario, but the priority of service A is higher than the priority of service B, in which case the first network element may choose, based on service A service experience insights, the RAT or access frequency by which the best experience for service A can be achieved.

In another example, the first network element determines, based on the previous two types of data analysis information, that the radio access information of the terminal device is RAT A, but the network load of RAT A (eg, NR) is already high and the user priority of the terminal device is low, and in in this case, the first network element may determine that RAT B (eg, E-UTRAN) should be selected as the radio access information for the terminal device.

S307: The first network element sends the first indication information to the third network element, the first indication information including the access information selection policy of the terminal device which is determined by the first network element.

Optionally, when the first network element is a core network element, a network administration network element, or a service server, the first network element sends the first indication information to the access network element or the terminal device, the first indication information may include the access information selection policy of the terminal device. According to this method, the access network element can cause, with reference to the access information selection policy, the terminal device to access the corresponding RAT or the corresponding access frequency, where the corresponding RAT is the same as or different from the target RAT, and the corresponding access frequency is the same. as or different from the target access frequency. Alternatively, according to this method, the terminal device may access, with reference to the access information selection policy, a corresponding RAT or a corresponding access frequency, where the corresponding RAT is the same as or different from the target RAT, and the corresponding access frequency is the same. as or different from the target access frequency.

Optionally, the first network element further sends the applicable access information selection policy condition to the access network element or the terminal device, wherein the applicable condition includes at least one of the following information: service type, user type, user ID, time information, and area information. . The applicable access information selection policy condition is used to indicate the specific conditions under which the access information selection policy is available.

Optionally, the access information selection policy which is related to the terminal device and which is sent by the first network element to the third network element may be an RFSP/SPID policy corresponding to the terminal device.

Optionally, the access information selection policy of the terminal device is dynamically changed depending on the scenario. In other words, the first network element dynamically updates the policy to the third network element, for example, updates the policy based on information about the network area of the terminal device or updates the policy based on different time intervals. Alternatively, the access information selection policy may be a dynamic global policy (the policy and the corresponding applicable condition (time, place, or the like)), and after the policy is delivered to the third network element, the third network element executes the policy dynamically. In an exemplary implementation, the first network element may only send the corresponding RFSP/SPIDs in one scenario at a time (time, place, or the like). If the first network element determines that the script of the terminal device is subsequently changed and the corresponding RFSP is changed, the first network element may further update the RFSP in the RAN.

In another possible implementation, the first network element may alternatively send at a time a plurality of RFSP/SPIDs corresponding to a terminal device in a plurality of scenarios (time, location, or the like) and indicate a condition (time, location, RAN load, or the like) to which each RFSP/SPID is applicable.

S308: The third network element determines and executes the binding policy of the terminal device based on the access information selection policy of the terminal device that is sent by the first network element.

The third network element may be an access network element or a terminal device.

Optionally, the terminal device's affinity policy may specifically be that the terminal device continues to be affixed to the original RAT or original access frequency, or may be that the terminal device is transitioned to accessing another RAT or another access frequency.

Optionally, when the third network element is an access network element, the policy of switching the terminal device to access another RAT or another access frequency that is executed by the third network element is specifically as follows: After the access network element selects an appropriate target RAT or appropriate target access frequency for the terminal device based on the first analytic information, if the terminal is in connected mode, the access network element can handover, through a handover procedure, the terminal device to the target cell corresponding to the target RAT or target access frequency. Alternatively, the access network element may send the associated target RAT or associated target access frequency to the terminal device via a redirection procedure such that upon entering the idle mode, the terminal device may choose to access the cell corresponding to the target RAT or target access frequency. In another example, after the access network element selects a proper target RAT or a proper target access rate for the terminal device based on the first analytic information, if the terminal is currently in the idle mode, the access network element may wait until the terminal the device will not enter connected mode. Alternatively, after the access network calls the terminal device to connected mode, the access network then allows the terminal device, using a redirection or connected mode handoff method, to access a cell corresponding to the target RAT or target access frequency.

Optionally, when the third network element is a terminal device, the policy of transferring the third network element to access another RAT or another access frequency is specifically as follows: The terminal device performs cell reselection or network reselection to access a cell corresponding to another RAT or another access frequency.

For example, if the terminal device determines, based on the RFSP sent by the first network element, that the current RAT or current access frequency has the highest priority, the terminal device determines that it should continue to be associated with the current RAT or current access frequency. If the terminal device determines, based on the RFSP sent by the first network element, that another RAT or another access frequency has the highest priority, the terminal device performs cell reselection or network reselection to access the cell corresponding to that other RAT or that other access frequency. Before the terminal device performs cell reselection or network reselection to access a cell corresponding to a different RAT or different access frequency, if the terminal device is in connected mode at the current RAT or the current access frequency, the terminal device may wait to enter the sleep mode, and then perform cell reselection or network reselection to access a cell corresponding to a different RAT or different access frequency.

S309: The terminal device accesses the target RAT or access frequency according to the indication of the third network element.

Note that this step is performed when the third network element is an access network element. If the third network element is a terminal device, the terminal device accesses the target RAT or access frequency and may initiate a service at the target RAT or access frequency.

By performing all of the above steps, it can be ensured that the terminal device is accessing the proper RAT or proper access frequency. The RAT or access frequency may simply ensure that the service experience for a service initiated by the terminal device now or in the future satisfies a predetermined condition, eg, the service experience of the terminal device is optimal.

Optionally, the data analysis network element can directly generate RAT related information or access frequency related information based on said data, and this RAT related information or access frequency related information is included in the corresponding information and sent to the first network element. That is, the data analysis network element directly prefers the RAT or access rate of the terminal device in the scenario for the first network element. Thus, the analysis processing network element may directly generate RAT-related information or access frequency-related information with reference to the data in Table 6 and Table 7 entered in step S302, or the analysis network element may first generate service experience analysis information in step S303 and service related operation analysis information in step S304, and then further generate RAT related information or access frequency related information of the terminal device based on these two types of analysis information in steps S303 and S304.

In the solution provided in this embodiment of the present application, the data analytics network element can perform statistical analysis on the relationship between service experience information and radio access information, and the data analytics network element can also perform statistical analysis on related information. service operation at the user level. According to the above two steps, the analytics network element can assist the first network element in formulating a radio access information selection policy for one terminal device. The policy is used to select the proper anchor RAT or proper anchor frequency for the terminal device in various scenarios, and this policy is formulated based on the type of service to be initiated or has been initiated by the terminal device, that is, the service type of the terminal device is taken into account, and the policy is dynamically changed. , so that the service experience of the terminal device can reach the specified condition.

FIG. 7 is a schematic representation of the interactions of another policy determination method according to an embodiment of this application.

The technical solution shown in FIG. 7 applies to the type of service to be performed by the terminal device or to the type of service to be initiated by the terminal device, that is, the first network element may determine the type of service to be initiated by the terminal device.

Optionally, after the first network element determines the service type of the terminal device (e.g., receives a service establishment request message initiated by AF for the terminal device), the first network element formulates an access selection policy based on the type of service initiated and, in combination with the first analytical information and thus the service experience for that type of service in the RAT or frequency of access that/which is specified in said policy satisfies the given condition. The specific steps are as follows:

S401: The first network element sends the first request message to the analytical processing network element.

The first request message is used to receive the first analytic information from the analytic data processing network element. The content of the first analytic information is similar to the content of the first analytic information in the embodiment of FIG. 5, and details are not given here again.

The method for the first network element to send the first request message to the analytics network element is similar to the method for the first network element to send the first request message to the analytics network element in the embodiment of FIG. 5, and details are not given here again.

In a particular implementation, the first request message may carry a second analytic processing identifier used to indicate that the first analytic information is being requested.

Optionally, the first network element may further include filtering information in the first request message to identify that the first analytic information corresponding to the filtering information or satisfying a filter condition, such as a time filter condition or a location filter condition, is being requested.

Optionally, the first network element may further include a message condition in the first request message to indicate to the analytic processing network element that two types of analytic information should be fed back based on the message condition. For example, the message condition may be a time set by a timer and is used to indicate to the analytic processing network element that the first analytic information should be fed back within a period of time after the first request message is received, or that the first analytic information should be fed back. information after the first analytic information satisfies a predetermined condition, or to report the first analytic information periodically.

S402: The data analysis network element receives the corresponding training data.

It should be understood that in order to obtain the service experience analytic information corresponding to the RAT or access frequency, the content of the training data obtained by the analytic processing network element and the method of obtaining are similar to those in step S303, and details will not be given here again. It should be noted that steps 402 and 403 are independent of step 401, and there is no time sequence between steps 402 and 403 and step 401. In other words, the data analytics network element can receive the associated training data in advance and generate the associated analytics, and it is not necessary to perform the associated operation only after receiving the first request message.

S404: The analytic processing network element sends a first response message to the first network element, the first response message including the first analytic information.

The first analysis information is the first analysis message corresponding to the first request message in step S401.

It should be understood that step S404 is similar to step S305, but the difference is that in step S305 it may also be necessary to obtain service-related performance analysis information, while the service-related performance information has been determined here and therefore the need receive insights on service-related performance is missing.

S405: The first network element receives a terminal device service establishment request message.

Optionally, the first network element receives a service establishment request message initiated by the AF for the terminal device, and the first network element formulates an access selection policy based on the type of service initiated and in combination with the first analytic information obtained from the analytic processing network element, and , in this case, the service experience for this type of service in the target RAT or target access frequency, which/which is specified in said policy, satisfies the given condition.

It should be understood that there is no time sequence between step 401 and step 405. In an exemplary implementation, step 405 may occur after step 401. In another possible implementation, step 405 may alternatively occur before step 401. That is, after the service type occurs at the terminal device, the first network element sends a first request message to the network element of the analytic data processing. Preferably, the first request message includes the type of service that has occurred, used to request the first analytic information of the corresponding type of service.

S406: The first network element obtains the first analytic information and determines the access information selection policy of the terminal device.

It should be understood that S406 is the same as S306, the only difference is that in this embodiment, the service type of the terminal device has been determined, and therefore there is no need to perform statistics collection or prediction on the service type of the terminal device.

S407: The first network element sends the first indication information to the third network element, the first indication information including the access information selection policy of the terminal device which is determined by the first network element.

It should be understood that the first network element sends the first indication information to the third network element. The method for sending the first indication information to the third network element is similar to that in step S307, and details are not given here again.

S408: The third network element determines and executes the terminal device's binding policy based on the access information selection policy of the terminal device that is sent by the first network element.

It should be understood that the method for determining and executing the terminal device binding policy by the third network element is similar to that in step S308, and details will not be given here again.

S409: The terminal device accesses the target RAT or access frequency according to the indication of the third network element.

It should be understood that the method of accessing the target RAT or access frequency by the terminal device is similar to that in step S309, and details will not be given here again.

In the solution provided in this embodiment of the present application, the data analytics network element can perform statistical analysis on the relationship between service experience information and radio access information. Based on this, the data analysis network element can assist the first network element in formulating a radio access information selection policy for one terminal device. The policy is used to select the proper anchor RAT or proper anchor frequency for the terminal device in various scenarios, and this policy is formulated based on the type of service to be initiated or has been initiated by the terminal device, that is, the service type of the terminal device is taken into account, and the policy is dynamically changed. , so that the service experience of the terminal device can reach the specified condition.

For example, the second request message is used to request service related performance insights in area A and/or service experience insights corresponding to the RAT/frequency of access in area A. The service related performance insights in area A may be service-related performance insights of each terminal device in area A, or may be service-related performance insights that are aggregated in area A.

S606: The second network element determines the power saving policy of the network area based on the second analytic information.

It should be understood that the second network element determines the power saving policy of the network area based on the second analytic information, similar to the method in step S502, and details are not given here again.

In an exemplary implementation, the second network element determines, based on analytic information about the service-related operation of the terminal device in the area, the number of users or the proportion of users (the proportion of the number of users who use the service to the total number of users in the area) of the type of service in the area, and determines , based on service experience analytic information that is based on radio access information, RAT or access frequency, by using which the service experience for a given service type can satisfy a given condition, for example, can be RAT or access frequency, by using which the optimal quality of service. Based on the received information, and in combination with the service requirement for network device resources or the power consumption information of the service, the second network element can determine the type of RAT/frequency required by the type of service in the area, as well as the amount of resources used for this type of service.

Similarly, for another type of service that occurs in the area, the second network element may determine, using a similar method, the type of access frequency or RAT required by that other type of service, as well as the amount of resources used by that other type of service. Finally, for a certain area, the second network element may collect and calculate the resource requirement of each RAT or each frequency, for example, the NR/2.6 GHz resource requirement in that area, to determine whether the corresponding RAT or frequency can be turned off/off. access or his/her needs to be enabled, or to determine whether to transfer the load of the RAT or access frequency to another RAT or access frequency, or to determine whether to increase or decrease the power consumption corresponding to the RAT or access frequency.

For example, the second analytic information received by the second network element from the data analytic network element is shown in Table 14.

Table 14

Analytical information Example Region Information Honeycomb 1 Time from 08:00 to 08:10 >Service ID information 1 Augmented Reality (AR) / Virtual Reality (VR) >>RAT corresponding to service 1 NR >>Number of terminal devices 100 >>Requirement for network device resources for service 1 50 units NR >Service ID information 2 Video online >>RAT corresponding to service 2 NR or eLTE >>Number of terminal devices 40 and 20 >>Resource requirement for service 2 30 NR units and 20 eLTE units >Service ID information 3 Long Term Development Voice Transmission (VoLTE) >>RAT corresponding to service 3 LTE >>Number of terminal devices 200 >>Requirement for network device resources for service 3 100 LTE units Total Resource Need 80 NR units, 20 eLTE units and 100 LTE units

Assuming that there are 100 NR network device units, 50 eLTE units, and 90 LTE units in the current network area, based on the analysis of the network device resource requirement described above, in the recommended implementation, the second network element may indicate to the network administration execution unit or access network element that that the 20 excess NR units should be turned off to reduce power consumption. In addition, the second network element may indicate to the network administration execution unit or the access network element to schedule 10 eLTE units to load balance the LTE units, for example, to convert the eLTE units to LTE units using air interface virtualization technology. Alternatively, the second network element indicates to the LTE base station that the overburden terminal device should be sent to the eLTE base station. For example, the LTE base station may transfer the access terminal device to the eLTE base station through forwarding, handover, or the like. Before turning off the redundant NR units, if the terminal device is not only distributed in 80 NR units, but is distributed in more than 80 NR units, but the load in some NR units is very low, preferably the second network element can first further centralize this terminal device in the actually required 80 NR units using the load transfer method, and then turn off the excess NR units.

In another possible implementation of this embodiment, the analytics network element sends analytics information about the service-related operation of the terminal device level (as shown in Table 6) instead of the analytics information about the service-related operation of the terminal device shown in Table 12, which is aggregated in the area, to the second network element. In this case, the second network element itself performs data analytics to obtain intermediate result 1: analytics about the service-related operation of the terminal device, which is aggregated in an area (as shown in Table 12). Likewise, the service experience analytics that corresponds to the RAT or access frequency and that is sent by the data analytics network element to the second network element may also be based on the terminal device layer rather than the service type layer. Thus, the second network element performs further analytic processing to obtain intermediate result 2: service experience analytic information corresponding to the service type layer RAT or service type layer access frequency. Finally, the second network element generates a network area power saving policy with reference to the two intermediate results described above generated by the second network element itself.

In another possible implementation, the data analytics network element sends to the second network element the service experience corresponding to the terminal device layer RAT or the terminal device layer access frequency, as well as analytic information about the service related operation of the terminal device layer. The second network element can also directly generate a network area power saving policy without generating an intermediate result.

It should be understood that in determining the power saving policy, the second network element ensures that the number or load of the terminal devices in NR or high frequency NR is as low/smaller as possible based on the service-related operation and service experience of the terminal device in the network area. Thus, NR or NR high frequency is turned off as much as possible to reduce power consumption, and it does not affect the quality of service of the terminal device in this area.
