Step 23: Send a user identifier response message to the network device, where the response message includes the target user identifier associated with the first user identifier.

Based on the above process, a specific reference case is: In the scenario where user-level information on the service side is imported into the wireless intelligent controller (RIC), when the Trusted AF/Local NEF/network management associated service side can obtain the external user identifier ( For example, when the external IP address (UE External IP Address) and the user internal identifier that can be obtained by the wireless network (such as the access and mobility management function terminal NGAP identifier AMF UE NGAP ID), the Trusted AF/Local NEF/network management needs to report according to the RIC The user identification AMF UE NGAP ID makes a single request to the AMF for the permanent identification of SUPI, so that the Trusted AF/Local NEF/network management can use SUPI to request the user's external IP address (UE External IP Address) from the SMF, thereby completing the AMF UE NGAP ID and UE External IP Address Associating, importing user-level information on the service side into the wireless network, the process description is shown in Figure 3, including the following steps:

Step 31: RIC sends a request to Trusted AF/Local NEF/network management to subscribe to user-level information on the service side, and the request carries the user identifier AMF UE NGAP ID available inside RIC;

Step 32: After the Trusted AF/Local NEF/network manager receives the request from the RIC, it sends a user identification request message to the AMF, which at least carries the AMF UE NGAP ID (ie, the first user identification) and the target user identification in the user identification request message type (the type of target user identity is SUPI);

Step 33: AMF queries the SUPI (target user identifier) of the corresponding user based on the AMF UE NGAP ID, and returns the queried SUPI to the Trusted AF/Local NEF/network management through a response message;

Step 34: Trusted AF/Local NEF/Network Manager carries the SUPI obtained from AMF to subscribe the user's external IP address (UE External IP Address) to SMF;

Step 35: SMF feedbacks the subscription success or failure response, queries the UE External IP Address of the corresponding user based on SUPI, and returns the UE External IP Address to the Trusted AF/Local NEF/network management in the form of a notification;

Step 36: Trusted AF/Local NEF/Network Management associates the UE External IP Address with the AMF UE NGAP ID based on the mapping relationship in steps 32 to 35, and generates and maintains a user identification association table;

Step 37: Trusted AF/Local NEF/Network Management queries the UE External IP Address corresponding to the AMF UE NGAP ID reported by the RIC in Step 31 based on the user identification association table, and carries the UE External IP Address to subscribe to the service-side user-level information to the application service;

Step 38: The application service notifies the Trusted AF/Local NEF/network management of the service-side user-level information, and the UE External IP Address is included in the notification;

Step 39: Trusted AF/Local NEF/Network Management notifies the RIC of the service-side user-level information based on the user-identity association table. The notification carries the AMF UE NGAP ID. The RIC can update the network configuration of the corresponding user based on the service-side The user's business completes the customized guarantee.

Among them, step 32 and step 33 are a specific implementation of the embodiment scheme of the present disclosure for the reference case of importing user-level information on the service side, that is, Trusted AF/Local NEF/network management as a network device performs a single SUPI permanent user identification A user identification request, and the AMF queries the SUPI of the corresponding user based on the AMF UE NGAP ID carried by the Trusted AF/Local NEF/network management, and returns the SUPI to the Trusted AF/Local NEF/network management.

In some embodiments of the present disclosure, optionally, the target user identifier may also be provided to the network device by subscribing to a notification service. This implementation scheme is suitable for obtaining temporary identities such as 5G-GUTI, UE NGAP ID, user IP address, etc., and it is necessary to monitor the changes of the temporary identities and obtain updated temporary identities.

Optionally, referring to FIG. 4 , an embodiment of providing the target user identifier to the network device by subscribing to the notification service includes:

Step 41: Receive the user ID subscription message sent by the network device, the user ID subscription message at least includes the first user ID and the type of the target user ID, the target user ID is associated with the first user ID, and the type different user IDs;

Step 42: Send the user identification response message to the network device; the response message may be a success or failure response.

Step 43: Query the target user ID associated with the first user ID according to the types of the first user ID and the target user ID;

Step 44: Send a notification message to the network device, where the notification message always includes the target user identifier associated with the first user identifier.

Optionally, sending a user identification notification message to the network device, where the notification message further includes after the target user identification associated with the first user identification:

Step 45: When the target user ID is updated, send a notification message to the network device, where the notification message includes the updated target user ID.

Based on the above process, a specific reference case is: in the scenario where wireless information is open to external application services, when Trusted AF/Local NEF/network management associates the user's external identity with the user's internal identity that can be obtained by the wireless network (such as associated with External UE IP Address and AMF UE NGAP ID), Trusted AF/Local NEF/Network Management needs to use the subscription permanent identifier SUPI obtained from SMF to subscribe AMF UE NGAP ID to AMF, so as to complete the association between AMF UE NGAP ID and UE External IP Address, The user-level information on the side is opened to the application service, and the process description is shown in Figure 5, including the following steps:

Step 51: The application service sends a subscription request to the Trusted AF/Local NEF/network management, carrying the UE External IP Address to subscribe to the user-level information on the wireless side.

Step 52: Trusted AF/Local NEF/Network Manager carries the UE External IP Address obtained from the application service to request SUPI from the SMF;

Step 53: SMF queries the SUPI of the corresponding user based on the received UE External IP Address, and returns the queried SUPI to the Trusted AF/Local NEF/network management;

Step 54: Trusted AF/Local NEF/network manager sends a user identification subscription request to AMF, carrying the type of target user identification (the target user identification class is AMF UE NGAP ID) and SUPI (ie the first user identification), and/or network equipment Address (i.e. Trusted AF/Local NEF/network management address);

Step 55: After receiving the subscription request, the AMF sends a success or failure response to the subscription request to Trusted AF/Local NEF/Network Management.

After receiving the subscription request, the AMF can query the authentication information of the Trusted AF/Local NEF/network management from the network function of the core network. Authorization or failed authentication, you can send a subscription request failure response to Trusted AF/network management.

Step 56: AMF queries the AMF UE NGAP ID (target user identifier) of the corresponding user based on SUPI, and notifies the Trusted AF/Local NEF/network manager of the AMF UE NGAP ID;

Step 57: If the AMF UE NGAP ID value subscribed by Trusted AF/Local NEF/Network Management in AMF is updated, then execute Step 58;

Step 58: When the AMF UE NGAP ID value subscribed by the Trusted AF/Local NEF/network management in the AMF is updated, notify the Trusted AF/Local NEF/network management of the updated AMF UE NGAP ID value based on the stored network device address;

Step 59: Trusted AF/Local NEF/Network Management associates the UE External IP Address with the AMF UE NGAP ID based on the user ID mapping relationship in steps 52 to 58, generates and maintains a user ID association table, and at the same time follows the user ID in the data table Update the user identification association relationship table according to the change situation;

Step 510: Trusted AF/Local NEF/Network Management queries the AMF UE NGAP ID corresponding to the UE External IP Address reported by the application service in Step 51 based on the user identification association table, and carries the AMF UE NGAP ID to subscribe to the RIC for the wireless side user level of the corresponding user information;

Step 511: RIC carrying AMF UE NGAP ID notifies the wireless side user-level information to Trusted AF/Local NEF/network management;

Step 512: Trusted AF/Local NEF/Network Management sends a notification to the application service based on the UE External IP Address based on the user identification association table, and the user-level information on the wireless side. The application service can update the service configuration based on the relevant information on the wireless side, and guarantee at the service level user experience.

Among them, steps 54 to 58 are a specific implementation of the solution of this embodiment for the wireless side user-level information opening reference case, that is, Trusted AF/Local NEF/network management subscribes AMF UE NGAP ID users to AMF as a network device ID, and AMF queries the corresponding user AMF UE NGAP ID for the SUPI carried by the Trusted AF/Local NEF/network management in the trusted domain of the core network, and notifies the target user identification AMF UE NGAP ID to the Trusted AF/Local NEF/network management. In addition, when the temporary user identifier AMF UE NGAP ID is updated, AMF will notify the Trusted AF/Local NEF/network management of the updated AMF UE NGAP ID.

In addition, step 51 and step 52 also involve another user identification acquisition method in the present disclosure, that is, SMF uses the user's external IP address to send a request to the network device Trusted AF/Local NEF/ The NMS provides the target user ID SUPI.
