Correspondingly, the consumer NF receives the discovery response sent by the NRF.

Step 110 : The consumer NF obtains a first Internet Protocol (IP) address of the terminal according to information included in the discovery response.

Under the circumstances of configuring multiple PDU sessions in a terminal, a terminal may have multiple IP addresses. For each PDU session, the terminal has an IP address corresponding to the corresponding PDU session. For example, the same terminal configures a PDU session for video playback with a first AF, a PDU session for chatting with a second AF, and a PDU session for web browsing with a third AF.

Exemplarily, the first IP address of the terminal is one or more IP addresses of all IP addresses of the terminal; Alternatively, the first IP address of the terminal is an IP address corresponding to the target NF among all IP addresses of the terminal.

The IP address of the terminal has a correspondence with the attribute information of the PDU session. The correspondence is stored in the consumer NF, or the correspondence is stored in another NF, but the consumer NF can query or read the corresponding relationship in the other NF.

Step 202 , the NRF sends a registration response to the AF.

Exemplarily, the registration response is NF Management Update_NF Update Response of Nnrf interface (Nnrf_NFManNnrf_NFManagement_NFUpdate_response).

Discovery Process (or Discovery Method) :

Step 203 , the NWDAF sends a discovery request to the NRF.

Optionally, the discovery request is an NF discovery request (Nnrf_NFDiscovery_request) of the Nnrf interface. A discovery request is a request for discovering a target NF.

Optionally, the discovery request includes at least one of an application ID, an event ID, a UE ID, and a requested data processing method.

Step 204 , the NRF sends a discovery response to the NWDAF.

Optionally, the discovery response is the NF discovery response (Nnrf_NFDiscovery_response) of the Nnrf interface.

Optionally, the discovery response includes a (target) AF ID of the target NF and at least one of S-NSSAI, DNN, and data processing method of the target NF.

Exemplarily, the NWDAF transmits a discovery request to the NRF in order to find a suitable AF and perform communication (eg, finding one AF and collecting UE data for this purpose), and in the discovery request, characteristic information of the target AF (eg, For example, at least one of an application ID, an event ID, a UE ID, and a requested data processing method), the NRF matches an appropriate target AF and returns the NWDAF with information of the target AF included in the discovery response, The discovery response includes one of S-NSSAI, DNN, and data processing method of the target AF.

For example, the AF is used to provide Internet services such as video browsing, web browsing, online games, and instant messengers for the UE. The UE accesses the Internet service provided by the AF through the PDU session, each PDU session has unique attribute information (for example, at least one of S-NSSAI and DNN), and the UE assigns one IP address to each PDU session. have NWDAF is a data detection and analysis network element, automatically detects and analyzes the mobile network based on network data, and further improves the resource utilization efficiency of the mobile network. For example, NWDAF analyzes UE data when one or more UEs use a certain Internet service to guide resource allocation of a subsequent mobile network. In the analysis processor, the NWDAF first acquires UE data of one or multiple UEs from the AF side and sets it as data to be analyzed.

Interaction process of NWDAF and target NF :

Step 205 : NWDAF sends a first message to UDM.

The first message is an event exposure subscription (Nudm_EventExposure_Subscribe) of the Nudm interface. Exemplarily, the first message includes at least one of a Subscription Permanent Identifier (SUPI), SNSSAI, and DNN. SUPI is one of UE IDs.

Step 206 : UDM sends a second message to NWDAF.

The second message is an event exposure notification (Nudm_EventExposure_Notify) of the Nudm interface. Exemplarily, the second message includes the SMF ID.

Step 207 : The NWDAF sends a third message to the SMF.

The third message is an event exposure subscription (Nsmf_EventExposure_Subscribe) of the Nsmf interface.

Exemplarily, the UE ID is included in the third message.

Step 208 : SMF sends a fourth message to NWDAF.

The fourth message is an event exposure notification (Nsmf_EventExposure__Notify) of the Nsmf interface. Exemplarily, the (first) IP address of the UE is included in the fourth message.

The (first) IP address of the UE is one or more of all IP addresses of the UE. Optionally, the (first) IP address of the UE is an IP address corresponding to the target AF among all IP addresses of the UE.

Step 209 : The NWDAF sends a fifth message to the target AF.

The fifth message is an event exposure subscription (Naf_EventExposure_Subscribe) of the Naf interface. Exemplarily, the fifth message includes the (first) IP address of the UE, and optionally also includes a SUPI, which is one of the UE IDs.

The NWDAF, which has obtained the UE ID, S-NSSAI, and DNN through the process of steps 205 to 209 described above, determines the SMF to serve for the corresponding UE based on the UE ID. NWDAF sends an inquiry request to SMF, the inquiry request includes at least one of S-NSSAI and DNN, and SMF uniquely determines a target PDU session according to at least one of S-NSSAI and DNN, and the target PDU The session is a PDU session between the corresponding UE and the target AF, and furthermore, the SMF feeds back the IP address of the target PDU session of the UE to the NWDAF. NWDAF then acquires the first IP address of the UE.

The NWDAF transmits the first IP address of the uniquely determined UE to the target AF, and uses the first IP address to indicate which UE corresponds to the target AF. In this way, all IP addresses of the UE are assigned to the target AF. transmission and reduce security problems.

Optionally, the aforementioned UEs can be multiple, for example, NWDAF needs to analyze multiple UEs in the same region or multiple UEs in the same network slice.

Optionally, the fifth message also includes the requested data processing method. The requested data processing method is used by the NWDAF to instruct the data processing method when the target AF requests data processing.

Step 210 : The target AF sends a sixth message to the NWDAF.

The sixth message is an event exposure notification (Naf_EventExposure_Notify) of the Naf interface. Exemplarily, the sixth message includes data, for example, the data is UE data of one or more UEs. The UE data may be data such as power consumption data of the UE, application program use record, application program use time, application program use experience or evaluation, movement trajectory, and the like.

Illustratively, the target AF may provide data to the NWDAF, and the corresponding data may be data processed by the target AF. For example, the target AF collects UE data of multiple UEs, processes the collected UE data, and transmits the processed UE data to the NWDAF. Exemplarily, in a process where the target AF provides data to the NWDAF, one or more pieces of data are processed using the data processing method included in the fifth message. Alternatively, process one or more data using the default or configured data processing method in the process where the target AF provides data to the NWDAF.

Optionally, under the situation that the UE data is data after processing, the sixth message also includes a data processing method used for the UE data.

NWDAF receives UE data of one or multiple UEs and then analyzes and processes these UE data.

As can be seen from this, the method provided by the present embodiment provides at least one information of S-NSSAI, DNN, and data processing method of the target NF in the registration process and the discovery process, so that the NRF can Provides a more feature-rich registration processor and discovery process to allow the consumer NF to provide information to the consumer NF, and to allow the consumer NF to perform subsequent interactions with the target NF using this information, Under, the signal quantity or the load quantity when the target NF performs interaction with multiple consumer NFs may be reduced.
