[0092] In some deployments, a gNB can include a centralized unit (CU) and a DU. A gNB can also include an active antenna unit (AAU). The CU implements part of the functions of the gNB, and the DU implements part of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, implements the radio resource control (RRC), and the functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocol and real-time services, and implements the functions of the radio link control (RLC) layer, the media / medium access control (MAC) layer, and the physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer eventually becomes the information of the PHY layer, or is transformed from the information of the PHY layer, under this architecture, high-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It can be understood that the access network device can be a device including one or more of the CU node, the DU node, and the AAU node. In addition, the CU can be divided into an access network device in the radio access network (RAN), or can be divided into an access network device in the core network (CN), which is not limited in the present application.

In the embodiments of the present application, the function of the user plane network element can be implemented.

[0096] 6. Access and mobility management function (AMF) network element: mainly used for mobility management and access management, etc., which can be used to realize the functions of the mobility management entity (MME) except for session management, such as access authorization / authentication, etc.

[0097] 7. Session management function (SMF) network element: mainly used for session management, terminal device internet protocol (IP) address allocation and management, selection and management of user plane function, terminal point of policy control and charging function interface, and downlink data notification, etc.

[0098] 8. Policy control function (PCF) network element: a unified policy framework for guiding network behavior, providing policy rule information for network elements (such as AMF, SMF network elements, etc.) or terminal devices, etc.

[0101] 11. Unified data management (UDM) network element: used for unified data management, 5G user data management, processing user identification, access authentication, registration, or mobility management, etc.

[0102] 12. Application function (AF) network element: used for data routing affected by applications, accessing network exposure function network elements, interacting with policy frameworks for policy control, etc.

[0103] 13. Network data analytics function network element (NWDAF): the NWDAF can have at least one of the following functions:

[0104] Data collection, model training, model feedback, analysis result inference, analysis result feedback, etc. Among them, the data collection function refers to collecting data from network elements, third-party servers, terminal devices or network management systems; the model training function refers to training a model based on relevant input data; the model feedback function refers to sending the trained machine learning model to a network element supporting the inference function; the analysis result inference function infers and determines the data analysis result based on the trained machine learning model and inference data; and the analysis result feedback function can provide the data analysis result to the network element, the third-party server, the terminal device or the network management system, which can assist the network in selecting the service quality parameter of the service, or assisting the network in performing traffic routing, or assisting the network in selecting the background traffic transmission strategy, etc.

[0105] The typical application scenarios of the NWDAF include customization or optimization of terminal parameters. That is, the NWDAF collects information such as user connection management, mobility management, session management, and access service, uses reliable analysis and prediction models to evaluate and analyze different types of users, builds user portraits, determines user movement trajectories and service usage habits, and optimizes user mobility management parameters and wireless resource management parameters; optimization of services (paths), that is, the NWDAF collects information such as network performance, service load in a specific area, and user service experience, uses reliable network performance analysis and prediction models to evaluate and analyze different types of services, builds service portraits, determines the internal correlation of quality of experience (QoE), service experience, service path or 5G quality of service (QoS) parameters, and optimizes service paths, service routing, 5G edge computing, and service corresponding 5G QoS; optimization of service parameters by AF, for example, vehicle networking is an important technology of 5G network, and in the automatic driving scenario of vehicle networking, prediction of network performance (such as QoS information and service load) of a base station to be passed through by a vehicle can improve the service quality of vehicle networking. For example, a vehicle networking server can determine whether to continue in the unmanned driving mode based on the prediction information of network performance. The NWDAF collects information such as network performance and service load in a specific area, uses reliable network performance analysis and prediction models to realize statistics and prediction of network performance, and assists AF in optimizing parameters.

[0106] In the embodiments of the present application, the NWDAF can be a separate network element or can be combined with other network elements. For example, the NWDAF network element can be combined with the AMF or combined with the SMF.

[0107] In addition, the network architecture can further include a network slice selection function (NSSF) for managing network slice related information, and a service communication proxy (SCP) for supporting indirect communication, i.e., message transfer and routing between a service invoking network element and a service providing network element, selection and discovery of the service providing network element, and the like. It should be understood that the above-mentioned communication system includes only exemplary network elements, and the present application is not limited thereto.

[0108] In the above network architecture, the N2 interface is an interface between the RAN and the AMF network element, for transmitting wireless parameters, non-access stratum (NAS) signaling, and the like; the N3 interface is an interface between the RAN and the UPF network element, for transmitting user plane data, and the like; the N4 interface is an interface between the SMF network element and the UPF network element, for transmitting information such as service policy, N3 connection tunnel identifier information, data caching instruction information, and downlink data notification message, and the like. The N6 interface is an interface between the DN network element and the UPF network element, for transmitting user plane data, and the like.

[0109] It should be understood that in the above network architecture, the network elements can interact with each other through service interfaces. For example, the NWDAF network element can collect data generated by the terminal on the network element through the service interface (such as Namf, Nsmf, etc.) provided by other network elements (such as AMF, SMF, etc.), and provide data analysis results (Analytics), model, also known as machine learning model, data, etc. through the Nnwdaf interface to other network elements (such as AMF, PCF, etc.).

[0110] It should be understood that the network architecture applied to the embodiments of the present application is only a network architecture described from the perspective of traditional point-to-point architecture and service architecture, and the network architecture applicable to the embodiments of the present application is not limited thereto. Any network architecture capable of realizing the functions of the above-mentioned network elements is applicable to the embodiments of the present application.

[0111] It should be noted that the names of various network elements and interfaces in the present application are only examples, and the present application does not exclude the case where various network elements are named otherwise in the future, and the functions of various network elements are merged. With the evolution of technology, any device or network element that can realize the functions of the above-mentioned network elements is within the protection scope of the present application. Secondly, the above-mentioned network elements can also be referred to as entities, devices, apparatuses or modules, etc., and the present application does not particularly limit them. Moreover, in the present application, in order to facilitate understanding and description, the description of "network element" is omitted in part of the description, for example, the NWDAF network element is simply referred to as NWDAF, in this case, the "NWDAF" should be understood as the NWDAF network element, and the same or similar cases are omitted below.

[0112] In Figure 1 In the network architecture shown, the NWDAF network element can register the information of its own network element (NWDAF Profile) in the NRF, and the NWDAF profile can include analysis type information, which can be identified by an analysis identifier (Analytics ID). Table 1 exemplarily shows the related content of Analytics ID:

[0113] Table 1

[0114]

[0115] Among them, if the information of the NWDAF includes any one or more analysis identifiers in Table 1, it means that the NWDAF supports the analysis type corresponding to the one or more analysis identifiers, for example, Analytics ID = ServiceExperience, which means that the NWDAF supports providing data analysis results of the service experience type.

[0116] The data analysis results corresponding to the above analysis types can be obtained by the NWDAF collecting UE data. The method for the NWDAF to collect data from the UE is defined in 3GPP Rel-17 23.288. Since there is no direct interface between the NWDAF and the UE defined in the current protocol, the NWDAF can collect data from the application (Application) of the UE through the AF, which is used to train the machine learning model and generate the data analysis result. Among them, the AF can belong to the operator network or the third party. The prior art defines the process of the NWDAF collecting data from the UE, but does not provide a method for the UE to obtain data analysis results from the NWDAF.

[0117] Therefore, the present application provides a communication method, so that the terminal device can obtain data analysis result from the data analysis network element according to the analysis type it is allowed to request. After obtaining the data analysis result, the terminal device can make a faster response according to the data analysis result, which can assist the terminal device to improve performance.

[0118] Hereinafter, without loss of generality, the interaction between network elements is taken as an example to illustrate the communication method provided by the embodiments of the present application in detail. Figure 2 is a schematic flow chart of a communication method provided by the present application. The method comprises at least the following steps.

[0119] S210, the first network element obtains the information of the analysis type requested by the terminal device (Requested Analytics ID).

[0120] The information of the analysis type requested by the terminal device can also be referred to as the information of the analysis type configured by the terminal device (Configured Analytics ID). The analysis type requested by the terminal device mentioned elsewhere in the present application can be replaced by the configured analysis type, which will not be described again.

[0121] Specifically, the first network element can obtain the information of the analysis type requested by the terminal device by receiving the first information sent by the terminal device. The first information can comprise the identification information of the terminal device, such as the subscription permanent identifier (SUPI), the permanent equipment identifier (PEI) or the generic public subscription identifier (GPSI); the first information can also comprise a first analysis identifier, which is used to identify the information of the analysis type requested by the terminal device; for example, the first information can also comprise analysis result filtering information, for example, the information of the area of interest (AOI) of the terminal device in the first information, i.e. the terminal device requests the data analysis result in the AOI, the AOI information can comprise one or more of the following: tracing area identifier (TAI), cell ID, geographical area identifier, network code (NC), country code (CC), city code, county code.

[0122] The first network element can be a core network element or an application function network element. In a possible implementation, the first network element is an access and mobility management function network element, and the first network element obtaining the analysis type requested by the terminal device includes: the access and mobility management function network element receiving a registration request message sent by the terminal device, the registration request message carrying the first information.

[0123] In another possible implementation, the first network element is a session management network element, and the first network element obtaining the information of the analysis type requested by the terminal device includes: the session management network element receiving a session establishment request message or a session modification request message sent by the terminal device, the session establishment request message or the session modification request message carrying the first information. Exemplarily, the session establishment request message or the session modification request message is a protocol data unit (PDU) session establishment request message or a PDU session modification request message. Exemplarily, the session management network element can also receive the first information sent by the terminal through a user plane function network element, the first information being obtained by the user plane function network element by analyzing a user plane uplink data packet. Alternatively, the session management network element can also receive a user plane uplink data packet sent by the terminal device through a user plane function network element, the user plane uplink data packet including the first information, and further, the session management network element analyzes the user plane uplink data packet to obtain the first information included in the user plane uplink data packet.

[0124] Exemplarily, if the session management network element analyzes the first information from the user plane uplink data packet sent by the user plane function network element, the method 200 can further include S201: the session management network element receiving indication information from the terminal device, the indication information being used to indicate that the terminal device will send the first information through a user plane, or the indication information being used to indicate that the terminal device will carry the first information in a user plane uplink data packet; and the session management network element sending a packet detection rule (PDR) corresponding to the first information to the user plane function network element according to the indication information. The PDR is used to assist the user plane function network element in sending the user plane uplink data packet including the first information to the session management network element. Alternatively, the PDR corresponds to the user plane uplink data packet including the first information. Accordingly, after the user plane function network element receives the user plane uplink data packet including the first information, the user plane function network element sends the user plane uplink data packet to the session management network element according to the PDR corresponding to the first information.

[0125] The specific form of the indication information is not limited in the embodiments of the present application. Exemplarily, the indication information can explicitly indicate the terminal device to send the first information through the user plane. For example, the first indication information is information of a certain bit, when the bit is "0", it indicates that the terminal device will send the first information through the user plane; or when the bit is "1", it indicates that the terminal device will send the first information through the user plane. The indication information can be named as analytic subscription indication. For another example, the indication information can implicitly indicate the terminal device to send the first information through the user plane. For example, the indication information is a preset data network name (DNN) and / or single network slice selection assistance information (S-NSSAI), if the PDU session establishment / modification request message sent by the terminal device to the session management network element includes the preset DNN and / or S-NSSAI, the session management network element determines that the terminal device will send the first information through the user plane.

[0126] In another possible implementation, the first network element is a user plane function network element, and the first network element obtaining the information of the analytics type requested by the terminal device includes: the user plane function network element receiving a user plane uplink data packet sent by the terminal device, the user plane uplink data packet including the first information. Further, the user plane function network element analyzes the user plane uplink data packet to obtain the first information.

[0127] In another possible implementation, the first network element can also be an application function network element, and the first network element obtaining the information of the analytics type requested by the terminal device includes: the application function network element receiving an application layer uplink data packet sent by the terminal device, the application layer uplink data packet including the first information.

[0128] S220, the first network element obtains the information of the analytics type (Subscribed Analytics ID) to which the terminal device subscribes.

[0129] Specifically, the first network element can request the subscription data of the terminal device from the unified data management network element or the application function network element. Exemplarily, the first network element can send a second request message to the unified data management network element or the application function network element, the second request message being used to request the information of the analytics type to which the terminal device subscribes, and the second request message can carry the identification information of the terminal device.

[0130] In a possible implementation, the first network element can be an access and mobility management function network element or a session management network element or a user plane function network element, and the second request message can be a subscription request message. Illustratively, the first network element subscribes to and obtains the information of the analysis type corresponding to the subscription of the terminal device identity information (i.e., SUPI or PEI or GPSI) from a unified data management (UDM) network element through a subscription data subscription (Nudm_SDM_Subscribe) service operation; correspondingly, the UDM feeds back the information of the analysis type to which the terminal device is subscribed to the first network element through a subscription data notification (Nudm_SDM_Notification) service operation. Alternatively, the first network element can also directly obtain the information of the analysis type to which the terminal device is subscribed from an application function network element. For example, the first network element subscribes to the information of the analysis type to which the terminal device is subscribed from the application function network element through an event exposure subscription (Naf_EventExposure_Subscribe) service operation; correspondingly, the application function network element feeds back the information of the analysis type to which the terminal device is subscribed to the first network element through an event exposure notification (Naf_EventExposure_Notify) service operation.

[0131] The UDM can be preconfigured with the information of the analysis type to which the terminal device is subscribed, or the application function network element can register the information of the analysis type to which the terminal device is subscribed to the UDM through a parameter provision (Nudm_ParameterProvision) service operation of the UDM network element.

[0132] If the first network element is a session management network element, the first request message can further include the identity information of an application of the terminal device, and the first network element obtains the information of the analysis type to which the terminal device is subscribed corresponding to the identity information of the application, that is, the analysis type to which the terminal device is subscribed obtained by the first network element can be of a terminal device granularity or of a service granularity.

[0133] It should be noted that if the analysis type to which the terminal device is subscribed changes (for example, a user package is changed) on the UDM, the UDM can send the information of the updated analysis type (Updated Subscribed Analytics ID) to the first network element through the subscription data notification service. Similarly, if the analysis type to which the terminal device is subscribed changes on the application function network element, the user function network element can also send the information of the updated analysis type to the first network element.

[0134] In another possible implementation, the first network element is an application function network element, and the first network element obtaining the information of the analysis type to which the terminal device is subscribed includes that the application function network element receiving the first information sent by the terminal device, the first information including IP address information of the terminal device; the application function network element obtaining, according to the IP address information of the terminal device, identification information of the terminal device, for example, SUPI or GPSI of the terminal device, and determining the information of the analysis type to which the terminal device is subscribed according to the identification information of the terminal device. The service type to which the terminal device is subscribed determined by the application function network element can also be service granularity, for example, the application function network element determining the analysis type corresponding to the identification information of the application of the terminal device.

[0135] In another possible implementation, the first network element is a network storage function network element, and the first network element obtaining the information of the analysis type to which the terminal device is subscribed includes that the network storage function network element receiving a first request message sent by an access and mobility management function network element or a session management network element or a user plane function network element or an application function network element, the first request message including the information of the analysis type requested by the terminal device and the information of the analysis type to which the terminal device is subscribed. That is, in the case where the first network element is a network storage function network element, the first network element can obtain the information of the analysis type requested by the terminal device and the information of the analysis type to which the terminal device is subscribed.

[0136] S230, the first network element obtaining the information of the analysis type supported by the data analysis network element.

[0137] In a possible implementation, the first network element is an access and mobility management function network element or a session management network element or a user plane function network element or an application function network element. The first network element can obtain the information of the analysis type supported by the data analysis network element through a network storage function network element. The data analysis network element can be a NWDAF, or can also be another network element with a data analysis function.

[0138] Specifically, the first network element can send a first request message to the network storage function network element, the first request message being used to request information of the data analysis network element. The first request message can carry at least one of the following information: information of an AOI of the terminal device, information of a location area in which the terminal device is located, for example, a cell or a tracking area in which the terminal device currently resides and is perceived by the first network element. The network storage function network element discovers a data analysis network element serving the AOI of the terminal device or the location area in which the terminal device is located, and information of the analysis type supported by the data analysis network element. The network storage function network element sends, to the first network element, the information of the data analysis network element through a response message, wherein the information of the data analysis network element includes the information of the analysis type supported by the data analysis network element.

[0139] The information of the data analytics network element can also carry the following information: identification information of the data analytics network element and / or address information of the data analytics network element. The address information of the data analytics network element can include IP address, fully qualified domain name (FQDN), uniform resource locator (URL) and the like of the data analytics network element.

[0140] Exemplarily, the first network element can request the information of the available data analytics network element and the information of the analysis types supported by the data analytics network element from the network storage function network element through a network function discovery request (Nnrf_NFDiscovery_Request) service operation. Correspondingly, the network storage function network element sends the information of the data analytics network element to the first network element through a network function discovery request response (Nnrf_NFDiscovery_Request Response) service operation, and the information of the data analytics network element includes the information of the analysis types supported by the data analytics network element.

[0141] Exemplarily, the first network element can also request the information of the analysis types supported by the data analytics network element from the data analytics network element according to the address information of the data analytics network element sent by the network storage function. Alternatively, in this implementation, the first network element can determine that the information of the data analytics network element received from the network storage function network element does not include the information of the analysis types supported by the data analytics network element, and request the information of the analysis types supported by the data analytics network element from the data analytics network element.

[0142] Exemplarily, the first network element can send a subscription request message to the data analytics network element through an available analysis type subscription (Nnwdaf_AvailableAnalytics_Subscribe) service operation of the NWDAF network element, and request the information of the analysis types supported by the data analytics network element; the data analytics network element sends the information of the analysis types supported by the data analytics network element to the first network element through an available analysis type notification (Nnwdaf_AvailableAnalytics_Notify) service operation of the NWDAF network element.

[0143] It should be noted that if the first network element receives the first information of multiple terminal devices, and the first information of the multiple terminal devices includes the information of multiple AOIs, the first network element can also form a list including the information of the AOIs of the multiple terminal devices, the information of the requested analysis types corresponding to each AOI, and the information of the subscribed analysis types, for example, the list can be expressed as list of<AOI, list of Requested Analytics ID, list of (Updated) Subscribed Analytics ID>, and then request the network storage function network element for the data analysis network element meeting the requirements according to the list.

[0144] Similarly, the data analysis network elements meeting the requirements discovered by the network storage function network element can include one or more, the network storage function network element can return a list of data analysis network elements meeting the conditions, the list of data analysis network elements meeting the conditions can include the identification information and / or address information of one or more data analysis network elements, and the information of the analysis types supported by the data analysis network elements; the first network element can select one data analysis network element from the list. Alternatively, the network storage function network element can also select one data analysis network from the list and send the information of the data analysis network to the first network element. The present application does not limit this.

[0145] The first network element can also obtain the updated information of the analysis types supported by the data analysis network element. For example, the first network element sends a subscription request message to the network storage function network element through the network function management network function network element state subscription request (Nnrf_NFManagement_NFStatusSubscribe) service operation, the subscription request message is used to request the network storage function network element to send a corresponding notification message to the first network element when the information of the analysis types supported by the data analysis network element changes (for example, the NWDAF can provide new analysis types for the terminal device, or the NWDAF can no longer provide some analysis types for the terminal device). The subscription request message can carry the identification information and / or address information of the data analysis network element, and the analytics update indication information, the analytics update indication information is used to instruct the network storage function network element to send a notification to the first network element when the information of the analysis types supported by the corresponding data analysis network element changes.

[0146] Correspondingly, when the analysis type supported by the data analytics network element changes, the network storage function network element sends the updated information to the first network element through a network function network element status notification (Nnrf_NFManagement_NFStatusNotify) service operation. The notification message sent by the network storage function network element can carry the identification information and / or address information of the data analytics network element, and the information of the updated analysis type supported by the data analytics network element.

[0147] Exemplarily, the first network element can also directly subscribe to the analysis type update notification from the data analytics network element. Exemplarily, the first network element can send a subscription request message to the data analytics network element through an Nnwdaf_AvailableAnalytics_Subscribe service operation, to request sending a notification to the first network element when the information of the analysis type provided by the data analytics network element changes; correspondingly, the data analytics network element sends the updated information of the analysis type supported by the data analytics network element to the first network element through an Nnwdaf_AvailableAnalytics_Notify service operation of the available analysis type notification of the NWDAF network element.

[0148] In another possible implementation, the first network element is a network storage function network element, and the first network element obtaining the information of the analysis type supported by the data analytics network element includes that the first network element receives a first request message sent by an access and mobility management function network element or a session management network element or a user plane function network element or an application function network element, and the first request message is used to request the information of the data analytics network element. The first request message can carry at least one of the following information: the information of the AOI of the terminal device, the information of the location area where the terminal device is located, and the information of the analysis type requested by the terminal device and the information of the analysis type subscribed by the terminal device. The network storage function network element discovers the data analytics network element serving the AOI and / or the location area where the terminal device is located, and the information of the analysis type supported by the data analytics network element.

[0149] S240, the first network element determines the allowed analysis type information (allowed Analytics ID) according to the information of the analysis type requested by the terminal device, the information of the analysis type subscribed by the terminal device, and the information of the analysis type supported by the data analytics network element.

[0150] In a possible implementation, the first network element takes the intersection of the information of the analysis type requested by the terminal device, the information of the analysis type subscribed by the terminal device, and the information of the analysis type supported by the data analytics network element, to determine the allowed analysis type information requested by the terminal device.

[0151] In another possible implementation, the first network element can also determine the allowed analysis type information requested by the terminal device by taking the intersection of any two of the analysis type information requested by the terminal device, the analysis type information subscribed by the terminal device, and the analysis type information supported by the data analytics network element.

[0152] If the first network element determines the allowed analysis type information requested by the terminal device by taking the intersection of any two of the analysis type information requested by the terminal device, the analysis type information subscribed by the terminal device, and the analysis type information supported by the data analytics network element, the first network element can also not perform the step of obtaining the information of the remaining analysis type. For example, the first network element determines the allowed analysis type information requested by the terminal device according to the analysis type information requested by the terminal device and the analysis type information subscribed by the terminal device, and the first network element can not perform the step S230.

[0153] In a possible implementation, the first network element is an access and mobility management function network element or a session management network element or a user plane function network element or an application function network element, and the first network element determines the intersection of the analysis type requested by the terminal device, the (updated) analysis type subscribed by the terminal device, and the (updated) analysis type supported by the data network element as the allowed analysis type requested by the terminal device.

[0154] In another possible implementation, the first network element is a network storage function network element, and the network storage function network element determines the allowed analysis type information requested by the terminal device according to the analysis type information requested by the terminal device and the (updated) analysis type information subscribed by the terminal device obtained from an access and mobility management function network element or a session management network element or a user plane function network element or an application function network, and the (updated) analysis type information supported by the data analytics network element determined by the network storage function network element.

[0155] S250, the first network element sends the allowed analysis type information requested by the terminal device to the terminal device.

[0156] In a possible implementation, the first network element is an access and mobility management function network element, and the first network element sends the allowed analysis type information requested by the terminal device to the terminal device through an access and mobility management function network element-access network device-terminal device path. That is, the access and mobility management function network element sends the data analytics result to the access network device, and the access network device sends the data analytics result to the terminal device. For example, the access and mobility management function network element sends a registration accept message to the terminal device, and the registration accept message includes the allowed analysis type information requested by the terminal device.

[0157] In another possible implementation, the first network element is a session management network element, and the first network element sends the information about the allowed analysis type requested by the terminal device to the terminal device through a session modification command message. For example, the session management network element sends an N1 session management (SM) container including a PDU session modification command to an access and mobility management function network element through a Namf_Communication_N1N2MessageTransfer service by invoking an AMF service interface, and the PDU session modification command includes the information about the allowed analysis type requested by the terminal device, and then the access and mobility management function network element transmits the N1 SM container to the terminal device. Exemplarily, the session management network element can also send a user plane downlink data packet to the terminal device through a user plane function network element, and the user plane downlink data packet includes the information about the allowed analysis type requested by the terminal device.

[0158] In another possible implementation, the first network element is a user plane network element, and the user plane network element sends the information about the allowed analysis type requested by the terminal device to the terminal device through a user plane downlink data packet.

[0159] In another possible implementation, the first network element is an application function network element, and the application function network element sends the information about the allowed analysis type requested by the terminal device to the terminal device through an application layer downlink data packet.

[0160] In another possible implementation, the first network element is a network storage function network element, and the network storage function network element can send the determined information about the allowed analysis type requested by the terminal device to an access and mobility management function network element or a session management function network element or a user plane function network element or an application function network element, and then the access and mobility management function network element or the session management function network element or the user plane function network element or the application function network element sends the information to the terminal device.

[0161] According to the method provided in the embodiments of the present application, the first network element can determine the information about the allowed analysis type obtained by the terminal device through the information about the analysis type requested by the terminal device, the information about the analysis type subscribed by the terminal device, and the information about the analysis type supported by the data analysis network element, and the first network element sends the information about the allowed analysis type obtained by the terminal device to the terminal device, so that the terminal device can obtain the data analysis result from the data analysis network element, and the performance of the terminal device is improved.

[0162] The different implementations of the method 200 will be described in detail below. Figures 3 to 9 The different implementations of the method 200 will be described in detail below.Figure 3 The communication method provided by the embodiments of the present application is described below by taking a first network element as an access and mobility management function network element (hereinafter referred to as AMF) as an example. As shown in the figure, the method comprises at least the following steps. Figure 3

[0163] S310, the UE sends first information to the AMF.

[0164] The first information comprises identification information of the terminal device and first analysis identification, and the first analysis identification is used to identify information of a requested analysis type (Requested or Configured Analytics ID). The identification information of the terminal device can refer to the description in S210. Exemplarily, the first information can further comprise analysis result filtering information, for example, information of an AOI of the terminal device is comprised in the first information.

[0165] Exemplarily, the terminal device can send a registration request to the AMF, and the registration request comprises the first information. The registration request initiated by the terminal device to the AMF can be an initial registration request, or a mobility registration update request or a periodic registration update request. If the UE is in an idle state and wants to subscribe to new data analysis results, the terminal device can initiate an initial registration request to the AMF; if the UE is in a connected state and wants to subscribe to new data analysis results, the terminal device can initiate the latter two registration requests.

[0166] S320, the AMF acquires information of a subscribed analysis type (Subscribed Analytics ID) of the terminal device.

[0167] In a possible implementation, S321a, the AMF subscribes to and acquires the subscribed analysis type of the terminal device from a UDM network element through a subscription data subscription (Nudm_SDM_Subscribe) service operation (an example of a second request message). Correspondingly, S322a, the UDM sends a second analysis identification to the AMF through a subscription data notification (Nudm_SDM_Notification) service operation, and the second analysis identification is used to identify information of the subscribed analysis type of the terminal device.

[0168] The subscribed analysis type of the terminal device can be preconfigured on the UDM; or the subscribed analysis type of the terminal device can be registered to the UDM by an application function (AF) through an Nudm_ParameterProvision service operation. ​

[0169] It should be noted that if the analysis type of the terminal device subscription on the UDM changes (for example, the user package changes), the UDM can send the updated analysis type information of the terminal device subscription to the AMF through the subscription data notification service.

[0170] In another possible implementation, the AMF can also directly obtain the analysis type of the subscription corresponding to the identification information of the terminal device from the AF.

[0171] For example, S321b, the AMF subscribes to the information of the analysis type of the subscription corresponding to the terminal device through the event exposure subscription (Naf_EventExposure_Subscribe) service operation (an example of the second request message) to the AF.

[0172] Correspondingly, S322b, the AF sends the second analysis identifier to the AMF through the event exposure notification (Naf_EventExposure_Notify) service operation, and the second analysis identifier is used to identify the information of the analysis type of the subscription corresponding to the terminal device.

[0173] Similarly, if the analysis type of the terminal device subscription on the AF changes (for example, the user package changes), the AF can send the updated analysis type to the AMF through the Naf_EventExposure_Notify service operation.

[0174] S330, the AMF obtains the information of the analysis type supported by the NWDAF.

[0175] In a possible implementation, the AMF can obtain the information of the NWDAF through the NRF.

[0176] For example, S331, the AMF can request the information of the available NWDAF from the NRF network element through the network function discovery request (Nnrf_NFDiscovery_Request) service operation, and the information of the NWDAF includes the information of the analysis type supported by the NWDAF.

[0177] The request message sent by the AMF can carry at least one of the following information: the information of the AOI of the terminal device, and the information of the location area where the terminal device is located.

[0178] Accordingly, S332, the NRF discovers the NWDAF serving the AOI or the location area where the terminal device is located, and the information of the analysis type supported by the NWDAF, and sends a third analysis identifier identifying the information of the analysis type supported by the NWDAF to the AMF through a network function discovery request response (Nnrf_NFDiscovery_Request Response) service operation.

[0179] The response message sent by the NRF can carry the following information: identification information and / or address information of the NWDAF, and the information of the analysis type supported by the NWDAF.

[0180] Exemplarily, the AMF can also send a subscription request message to the NRF through a network function network element state subscription (Nnrf_NFManagement_NFStatusSubscribe) service operation, requesting to send a corresponding notification message when the information of the analysis type supported by the NWDAF changes. The subscription request message can carry the identification information and / or address information of the NWDAF and analysis update indication information, which is used to instruct the NRF to send a notification to the AMF when the information of the analysis type supported by the corresponding NWDAF changes.

[0181] Accordingly, when the information of the analysis type supported by the NWDAF changes, the NRF can send the updated result to the AMF through a network function state notification (Nnrf_NFManagement_NFStatusNotify) service operation. The notification message sent by the NRF can carry the identification information and / or address information of the NWDAF, and the updated information of the analysis type supported by the NWDAF.

[0182] Exemplarily, S333, the AMF can also subscribe to the information of the analysis type supported by the NWDAF or the updated information of the analysis type supported by the NWDAF according to the address information of the NWDAF sent by the NRF.

[0183] Exemplarily, the AMF can send a subscription request message to the NWDAF through a NWDAF network element available analysis type subscription Nnwdaf_AvailableAnalytics_Subscribe service operation, for requesting the information of the analysis type supported by the NWDAF, or requesting to send a corresponding notification when the information of the analysis type supported by the NWDAF changes. The subscription request message can carry the address information of the NWDAF; the subscription request message can also carry analysis update indication information, which is used to instruct the NWDAF to send a notification message to the AMF when the information of the analysis type supported by the NWDAF changes.

[0184] Correspondingly, when the information of the analysis type supported by the NWDAF changes, the NWDAF sends the updated result to the AMF through the Nnwdaf_AvailableAnalytics_Notify service operation.

[0185] S340, the AMF determines the information of the analysis type allowed to be requested by the terminal device.

[0186] After the AMF obtains the information of the analysis type to which the terminal device is subscribed, the information of the analysis type supported by the NWDAF, and the information of the analysis type requested by the terminal device, the three kinds of information can be intersected or any two of the three kinds of information are intersected to determine the information of the analysis type allowed to be obtained by the terminal device, which is similar to S240; or the AMF can also update the information of the analysis type allowed to be requested by the terminal device according to the updated information of the analysis type to which the terminal device is subscribed and the updated information of the analysis type supported by the NWDAF, and the information of the analysis type requested by the terminal device.

[0187] S350, the AMF sends the information of the analysis type allowed to be requested by the terminal device to the terminal device. Correspondingly, the terminal device receives the information.

[0188] Exemplarily, the AMF can send a registration accept message to the terminal device, and the registration accept message carries the information of the analysis type allowed to be requested by the terminal device.

[0189] Exemplarily, S360, the terminal device requests the data analysis result from the NWDAF according to the information of the allowed requested analysis type.

[0194] ​In a possible implementation, the AMF can subscribe to and acquire the information of the analysis type to which the terminal device subscribes from the UDM, S421a. Accordingly, the UDM sends the second analysis identifier to the AMF, the second analysis identifier being used to identify the information of the analysis type to which the terminal device subscribes, S422a. This step is similar to S321a-S322a.

[0195] Exemplarily, the AMF can also acquire the information of the analysis type to which the terminal device subscribes directly from the AF.

[0196] Exemplarily, the AMF subscribes to the information of the analysis type to which the terminal device subscribes from the AF through a Naf_EventExposure_Subscribe service operation, S421b. Accordingly, the AF sends the second analysis identifier to the AMF through a Naf_EventExposure_Notify service operation, S422b. This step is similar to S321b-S322b.

[0197] If the information of the analysis type to which the terminal device subscribes changes, the UDM or the AF can send the updated information of the analysis type to which the terminal device subscribes to the AMF. This step is similar to S320.

[0199] The first request message can also carry at least one of the following information: the information of the AOI of the terminal device, the information of the location area in which the terminal device is located.

[0200] Exemplarily, the AMF can request the available NWDAF and the information of the analysis type supported by the NWDAF from the NRF network element through a network function discovery request (Nnrf_NFDiscovery_Request) service operation, the network function discovery request carrying the information of the analysis type requested by the terminal device and the information of the analysis type to which the terminal device subscribes.

[0201] Exemplarily, the AMF can also send a subscription request message to the NRF through a Nnrf_NFManagement_NFStatusSubscribe service operation, the subscription request message being used to request the updated information of the data analysis network element when the information of the analysis type supported by the NWDAF changes.

[0203] Exemplarily, the NRF can also, according to the subscription request message, when the information about the analysis types supported by the NWDAF changes, re-determine the information about the analysis types allowed to be requested by the terminal device by taking the intersection of the updated information about the analysis types supported by the NWDAF, the information about the analysis types requested by the terminal device (updated), and the information about the analysis types to which the terminal device subscribes.

[0208] Exemplarily, S470, the terminal device requests the data analysis result from the NWDAF according to the information about the analysis types allowed to be requested.

[0209] According to the method provided in the embodiments of the present application, the AMF or the NRF can determine the information about the analysis types (first analysis types) allowed to be acquired by the terminal device according to the information about the analysis types requested by the terminal device, the information about the analysis types to which the terminal device subscribes, and the information about the analysis types supported by the NWDAF, and the AMF sends the information about the first analysis types to the terminal device, so that the terminal device can acquire the data analysis result from the data analysis network element, and the performance of the terminal device is improved.

[0210] Figure 5 The communication method provided in the embodiments of the present application is described below by taking a first network element as a session management network element (hereinafter referred to as SMF) as an example. As shown in FIG. 4, the communication method comprises the following steps. Figure 5As shown, the method comprises at least the following steps.

[0211] S510, the UE sends first information to the SMF.

[0212] The first information comprises identification information of the terminal device and first analysis identification, the first analysis identification being information for identifying a type of analysis result requested by the terminal device.

[0213] Exemplarily, the first information can further comprise analysis result filtering information, which is similar to that in S310 and will not be described herein again.

[0214] Exemplarily, the UE sends a PDU session establishment request message to the SMF, the PDU session establishment request message comprising the first information.

[0215] S520, the SMF acquires second analysis identification, the second analysis identification being information for identifying a type of analysis subscribed by the UE.

[0216] In a possible implementation, S521a, the SMF subscribes to and acquires the second analysis identification from a UDM network element through a subscription data Nudm_SDM_SubscribeRequest service operation (an example of a second request message).

[0217] The second request message can comprise identification information of the terminal device, and exemplarily, the subscription request message can further comprise application identification (application identifier, App ID) of the terminal device, the App ID being used for identifying the second analysis identification requested by the SMF corresponding to a service. That is, the information of the type of analysis subscribed by the terminal device from the UDM requested by the SMF can be service-granularity.

[0218] Correspondingly, S522a, the UDM feeds back the second analysis identification to the SMF through a subscription data notification Nudm_SDM_Notification service operation; in addition, if the information of the type of analysis subscribed by the terminal device on the UDM changes (for example, a user package is changed), the UDM can also send the updated information of the type of analysis subscribed by the terminal device to the SMF through the subscription data notification Nudm_SDM_Notification service operation.

[0219] The UDM can be preconfigured with the type of analysis subscribed by the terminal device; or, the type of analysis subscribed by the terminal device can be registered to the UDM by an application function (AF) through a Nudm_ParameterProvisionning service operation.

[0220] In another possible implementation, the SMF can also obtain the second analytics identifier directly from the AF.

Exemplarily, the subscription request message can also include the App ID.

[0222] Correspondingly, S522b, the AF feeds back the information of the analytics type to which the terminal device is subscribed to the AMF by the Naf_EventExposure_Notify service operation. If the information of the analytics type to which the terminal device is subscribed to configured on the AF is of the terminal device granularity, the AF determines the information of the analytics type to which the terminal device is subscribed to according to the identification information of the terminal device; or if the information of the analytics type to which the terminal device is subscribed to configured on the AF is of the service granularity, the AF determines the information of the analytics type to which the terminal device is subscribed to according to the App ID. Similarly, if the information of the analytics type to which the terminal device is subscribed to configured on the AF changes, the AF can send the updated information of the analytics type to which the terminal device is subscribed to the AMF by the Naf_EventExposure_Notify service operation.

[0224] Exemplarily, the SMF can request (an example of the first request message) the information of the available NWDAF from the NRF network element by the Nnrf_NFDiscovery_Request service operation. The request message sent by the SMF can carry at least one of the following information: the information of the AOI of the terminal device, the information of the location area where the terminal device is located.

[0225] Correspondingly, S532, the NRF discovers the NWDAF serving the AOI or the area where the terminal device is located, and the information of the analytics type supported by the NWDAF, and sends the information of the NWDAF to the SMF by the Nnrf_NFDiscovery_Response service operation, wherein the information of the NWDAF includes the information of the analytics type supported by the NWDAF. The information of the NWDAF can also carry the identification information and / or address information of the NWDAF.

[0226] Exemplarily, the SMF can also send a subscription request message to the NRF through the Nnrf_NFManagement_NFStatusSubscribe service operation, for requesting to send a corresponding notification message when the information of the analysis type supported by the NWDAF changes. Correspondingly, when the information of the analysis type supported by the NWDAF changes, the NRF sends the updated result to the SMF through the Nnrf_NFManagement_NFStatusNotify service operation, and the notification message sent by the NRF can carry the information of the NWDAF, which includes: the updated information of the analysis type supported by the NWDAF. The information of the NWDAF can also include: the identification information and / or address information of the NWDAF.

[0227] Exemplarily, S533, the SMF can also directly request the NWDAF for the (updated) analysis type supported by the NWDAF.

[0228] Exemplarily, the SMF can send a subscription request message to the NWDAF through the Nnwdaf_AvailableAnalytics_Subscribe service operation, for requesting the information of the analysis type supported by the NWDAF, or for requesting to send a corresponding notification when the information of the analysis type supported by the NWDAF changes. The subscription request message can carry the identification information and / or address information of the NWDAF. Exemplarily, the subscription request message can also carry analysis update indication information, for indicating that the NWDAF sends a notification message to the SMF when the analysis type supported by the NWDAF changes.

[0229] Correspondingly, S534, the NWDAF sends the information of the analysis type supported by the NWDAF to the SMF through the Nnwdaf_AvailableAnalytics_Notify service operation.

[0230] S540, the SMF determines the information of the allowed analysis type (Allowed Analytics ID) requested by the terminal device.

[0231] This step is similar to S240; or, the SMF can also update the information of the allowed analysis type requested by the terminal device according to the updated information of the analysis type subscribed by the terminal device and the information of the analysis type supported by the NWDAF, and the information of the analysis type requested by the terminal device.

[0232] S550, the SMF sends the information of the allowed analysis type requested by the terminal device to the terminal device. Correspondingly, the terminal device receives the information.

[0233] Exemplarily, the SMF can send a PDU session establishment accept message to the terminal device, and the PDU session establishment accept message carries information of allowed analysis types requested by the terminal device.

[0234] Exemplarily, in S560, the terminal device requests a data analysis result from the NWDAF according to the information of allowed analysis types requested.

[0235] Figure 6 The communication method provided by the embodiments of the present application is described by taking a first network element as an example of a network storage function network element (hereinafter referred to as NRF). Figure 6 As shown in the figure, the method comprises the following steps.

[0236] In S610, the UE sends first information to the SMF.

[0237] The first information comprises identification information of the terminal device and information of a type of analysis result requested by the terminal device. Exemplarily, the first information can also comprise analysis result filtering information. This step is similar to S510, and will not be described here again.

[0238] In S620, the SMF acquires information of analysis types to which the terminal device subscribes.

[0239] In one possible implementation, the SMF subscribes to and acquires information of analysis types to which the terminal device subscribes from a UDM network element, comprising steps S621a to S622a. Exemplarily, the SMF can also acquire information of analysis types to which the terminal device subscribes directly from an AF, comprising steps S621b to S622b, and the process is similar to S520.

[0240] Similarly, if the information of analysis types to which the terminal device subscribes changes on the UDM or the AF, the UDM or the AF can also send updated information of analysis types to which the terminal device subscribes to the SMF.

[0241] In S630, the SMF sends a first request message to the NRF, and the first request message carries information of analysis types requested by the terminal device and information of analysis types to which the terminal device subscribes. Correspondingly, the NRF receives the first request message.

[0242] The first request message can also carry at least one of the following information: information of an AOI of the terminal device, and information of a location area in which the terminal device is located.

[0243] In S640, the NRF discovers a NWDAF serving the AOI or the location area in which the terminal device is located, and information of analysis types supported by the NWDAF, and determines information of allowed analysis types requested by the terminal device.

[0244] The NRF can send a response message to the SMF. The response message can carry the following information: identification information and / or address information of the NWDAF, and information of the allowed analysis type requested by the terminal device.

[0245] Exemplarily, the NRF can also re-determine the information of the allowed analysis type requested by the terminal device according to the updated information of the analysis type supported by the NWDAF, the received information of the analysis type requested by the terminal device, and the information of the analysis type to which the terminal device is subscribed (updated).

[0246] S650, the NRF sends the information of the allowed analysis type requested by the terminal device to the SMF.

[0247] S660, the SMF sends the information of the allowed analysis type requested by the terminal device to the terminal device. Accordingly, the terminal device receives the information. This step is similar to S560.

[0248] Exemplarily, S670, the terminal device requests the NWDAF for a data analysis result according to the allowed analysis type.

[0249] According to the method provided by the embodiments of the present application, the SMF or the NRF can determine the information of the allowed analysis type (first analysis type) obtained by the terminal device according to the information of the analysis type requested by the terminal device, the information of the analysis type to which the terminal device is subscribed, and the information of the analysis type supported by the NWDAF, and the SMF can send the information of the first analysis type to the terminal device, so that the terminal device can obtain a data analysis result from the data analysis network element, and the performance of the terminal device is improved.

[0250] Figure 7 The communication method provided by the embodiments of the present application is described below with the first network element as an example of a session management network element (hereinafter referred to as SMF). As shown in Figure 7 The method includes at least the following steps.

[0251] S701, the UE sends a PDU session establishment request message to the SMF.

[0252] The PDU session establishment request message includes indication information, which is used to indicate that the UE will send analysis subscription information through a user plane. More description of the indication information can be referred to S210.

[0253] S702, the SMF performs N4 session establishment with the UPF.

[0254] Specifically, the SMF sends an N4 session establishment request message to the UPF. The N4 session establishment request message includes a PDR corresponding to the analysis subscription information, and the PDR is used to assist the UPF to send the user plane uplink data packet including the analysis subscription information to the SMF. For example, the PDR includes a correspondence relationship between a QFI and address information of the SMF, and the QFI is used to identify a QoS flow of a session in which the UE transmits the analysis subscription information and receives the data analysis result.

[0255] Correspondingly, the UPF sends an N4 session establishment response message to the SMF.

[0256] S703, the SMF sends a PDU session establishment accept message to the UE.

[0257] S710, the UE sends a user plane uplink data packet (an example of the first information) to the UPF.

[0258] The uplink data packet includes a first analysis identifier, and the first analysis identifier is used to identify the analysis type requested by the UE.

[0259] Exemplarily, the user plane uplink data packet can include analysis result filtering information, for example, information of an area of interest (AOI) of the terminal device.

[0260] S720, the UPF forwards the user plane uplink data packet to the SMF according to the PDR and the QFI.

[0261] S730, the SMF obtains the information of the analysis type requested by the terminal device.

[0262] Specifically, the SMF can parse the uplink data packet and extract the first analysis identifier therefrom, that is, obtain the information of the analysis type requested by the terminal device.

[0263] Exemplarily, in step S720, the UPF can first parse the user plane uplink data packet from the UE, extract the first analysis identifier, and then send the first analysis identifier to the SMF; correspondingly, in step S730, the SMF obtains the first analysis identifier from the UPF, that is, obtains the information of the analysis type requested by the terminal device.

[0264] S740, the SMF obtains the information of the analysis type to which the terminal device subscribes.

[0265] The SMF can subscribe to and acquire the information of the analytics type to which the terminal device subscribes from the UDM network element through the subscription data by using the Nudm_SDM_Subscribe Request service operation (including steps S741a-S742a), which is similar to S621a-S622a; and the SMF can also acquire the information of the analytics type to which the terminal device subscribes directly from the AF (including steps S741b-S742b), which is similar to S621b-S622b.

[0266] The SMF acquires the information of the analytics type supported by the NWDAF (S750).

[0267] The SMF can acquire the analytics type supported by the NWDAF through the NRF (including steps S751a-S752a), which is similar to S531-S532. Alternatively, the SMF can also request the information of the analytics type supported by the NWDAF directly (including steps S753-S754), which is similar to S531-S534, and details are not repeated here.

[0268] The SMF determines the information of the allowed analytics type requested by the terminal device (S760).

[0269] This step is similar to S240, and details are not repeated here.

[0270] The SMF sends the information of the allowed analytics type requested by the terminal device to the terminal device (S770).

[0271] The SMF sends a user plane downlink data packet to the terminal device through the UPF, and the user plane downlink data packet carries the information of the fourth analytics identifier used to identify the information of the allowed analytics type requested by the terminal device. Alternatively, the SMF sends the information of the fourth analytics identifier to the UPF, and the UPF encapsulates the information of the fourth analytics identifier into a user plane downlink data packet and sends the encapsulated user plane downlink data packet to the terminal device.

[0272] In the above step S750, the SMF can also send the information of the analytics identifier requested by the terminal device and the information of the analytics identifier to which the terminal device subscribes to the NRF, and the NRF determines the information of the analytics identifier supported by the NWDAF and the fourth analytics identifier (including steps S751b-S752b and S760b). Subsequently, the fourth analytics identifier is sent to the SMF by the NRF and to the terminal device by the SMF.

[0273] According to the method provided in the embodiments of the present application, the SMF or the NRF network element can determine the analysis type (first analysis type) allowed to be obtained by the terminal device according to the analysis type information requested by the terminal device, the analysis type information subscribed by the terminal device, and the analysis type information supported by the NWDAF, and the SMF network element can send the first analysis type to the terminal device, so that the terminal device can obtain the data analysis result of the NWDAF.

[0274] In Figure 7 In the communication method shown in the figure, the UPF forwards the user plane uplink data packet or the parsed analysis type information requested by the terminal device to the SMF after receiving the user plane uplink data packet, and the SMF or the NRF determines the analysis type information allowed to be requested by the terminal device. For example, after the UPF receives the user plane uplink data packet, the UPF can also parse the data packet by itself and determine the analysis type information allowed to be requested by the terminal device.

[0275] Figure 8 The communication method provided in the embodiments of the present application is described taking the first network element as the UPF network element. The method includes at least the following steps.

[0276] S801, the UE sends a PDU session establishment request message to the SMF.

[0277] The PDU session establishment request message includes indication information, which is used to indicate that the UE will send analysis subscription information through the user plane. Similar to S701.

[0278] S802, the SMF performs N4 session establishment with the UPF.

[0279] Similar to step S702.

[0280] Correspondingly, the UPF sends an N4 session establishment response message to the SMF.

[0281] S803, the SMF sends a PDU session establishment acceptance message to the UE.

[0283] The uplink data packet includes a first analysis identifier, which is used to identify the analysis type information requested by the UE.

[0284] For example, the user plane uplink data packet can include analysis result filtering information.

[0285] S820, the UPF obtains the analysis type information requested by the terminal device.

[0286] The UPF parses the user plane uplink data packet and extracts the first analysis identifier therefrom to obtain the information of the analysis type requested by the terminal device.

[0287] The UPF obtains the information of the analysis type to which the terminal device is subscribed.

[0288] Similar to S741a-S742a, the UPF can subscribe to and obtain (updated) information of the analysis type to which the terminal device is subscribed by subscribing to the Nudm_SDM_SubscribeRequest service operation of the UDM network element through the subscription data; and similar to S741b-S742b, the UPF can also directly obtain the information of the analysis type to which the terminal device is (updated) subscribed from the AF.

Subsequently, the fourth analysis identifier is sent by the NRF to the UPF and by the UPF to the terminal device.

[0295] For example, in S870, the terminal device requests the data analysis result from the NWDAF according to the information of the allowed requested analysis type.

[0296] According to the method provided in the embodiments of the present application, the UPF or the NRF can determine the information of the analysis type (the first analysis type) allowed to be requested by the terminal device according to the information of the analysis type requested by the terminal device, the information of the analysis type subscribed by the terminal device, and the information of the analysis type supported by the NWDAF, and the UPF network element sends the information of the first analysis type to the terminal device, so that the terminal device can obtain the data analysis result from the NWDAF.

[0299] The application layer uplink data packet also carries the address information of the terminal device, for example, the IP address of the terminal device.

[0300] For example, the application layer uplink data packet can also include analysis result filtering information.

[0301] S920, the AF obtains the identification information of the terminal device.

[0302] The AF can obtain the identification information of the terminal device from a binding support function (BSF) according to the address information of the terminal device. For example, the identification information can be SUPI or GPSI.

[0303] For example, the AF can obtain the identification information of the terminal device from the BSF network element through the NEF.

[0304] S930, the AF determines the information of the analysis type subscribed by the terminal device.

[0305] The AF can determine the information of the analysis type subscribed by the terminal device according to the identification information of the terminal device, or determine the information of the analysis type subscribed by the terminal device according to the identification information of the terminal device and the identification information of the application.

[0306] S940, the AF obtains the information of the analysis type supported by the NWDAF.

[0307] The AF can obtain the analysis type supported by the NWDAF through the NRF. Alternatively, the AF can also directly obtain the information of the analysis type supported by the NWDAF. This step is similar to S333, and will not be described here.

[0308] Exemplarily, the AF can also send a subscription request message to the NRF or the NWDAF, requesting to send a corresponding notification message when the analysis type supported by the NWDAF changes.

[0309] S950a, the AF determines the information of the allowed analysis type requested by the terminal device.

[0310] This step is similar to S240, which is not described here.

[0311] S960, the AF sends the information of the allowed analysis type requested by the terminal device to the terminal device through an application layer downlink data packet.

[0312] In the above step S940, the AF can also send the information of the analysis type requested by the terminal device and the information of the analysis type subscribed by the terminal device to the NRF, and the NRF determines the information of the analysis type supported by the NWDAF and the information of the allowed analysis type requested by the terminal device (the fourth analysis identifier). This step is similar to S630. Subsequently, the fourth analysis identifier is sent to the AF by the NRF and to the terminal device by the AF.

[0313] It should be noted that the AF can belong to an operator network or a third party. When the AF belongs to a third party, steps S920 to S940 can be operated through the NEF.

[0314] Exemplarily, the AF can send a subscription request to the NEF through the Nnef_AnalyticsExposure_Subscribe service operation, for requesting the information of the analysis type supported by the NWDAF; the NEF can request the information of the analysis type supported by the NWDAF by sending the Nnwdaf_AnalyticsSubscription_Subscribe service operation to the NWDAF according to the subscription request; and the NWDAF can send a subscription notification to the AF through the NEF, wherein the subscription notification includes the information of the analysis type supported by the NWDAF.
