[0088] It is assumed that in this embodiment, the service network element is an AMF network element, and the user data management network element is a UDM network element. like image 3 As shown, in the registration process initiated by the terminal (UE), the service network element subscribes to the UDM network element. The AMF network element sends a registration request message to the UDM network element, and carries the first subscription context information used to indicate the subscription requirement. The UDM network element feeds back a registration request response message to the AMF network element based on the registration request message carrying the first subscription context information, and carries the second subscription context information in it to identify the subscription result. Of course, after receiving the registration request response message, the AMF network element may obtain subscription data from the UDM network element according to the normal regis...

[0091] It is assumed that in this embodiment, the service network element is an AMF network element, and the user data management network element is a UDM network element. like Figure 4 As shown, in the registration process initiated by the terminal (UE), the AMF network element registers with the UDM network element according to the normal registration process, and receives the registration response fed back by the DUM network element; then, the AMF network element sends the subscription data to the UDM network element request message, and carry the first subscription context information used to indicate the subscription requirement; the UDM network element feeds back the subscription data request response message to the AMF network element based on the subscription data request message carrying the first subscription context information, and carries the subscription data request response message in it. The second subscription context information identifies the subscription ...

Abstract

An embodiment of the present invention provides a subscription method, a service network element, and a user data management network element, wherein the method includes: sending a first request message to the user data management network element, and the first request message is a registration request message or a subscription data request message, and the first request message carries the first subscription context information to indicate the subscription requirement; receive the first response message fed back by the user data management network element based on the first request message, wherein the first response The message is a registration request response message or a subscription data request response message, and the first response message carries second subscription context information to indicate a subscription result corresponding to the subscription requirement. The embodiment of the present invention reduces the number of signaling interactions in the process of registration or session establishment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a subscription method, a service network element and a user data management network element. Background technique [0002] In a mobile communication system, when a terminal registers with a network or establishes a session, the service network element needs to register with a unified data management network element (Unified Data Manager, user data management network element) to obtain subscription data, and subscribe to related services; and the terminal deregisters , When the released session or the released session belongs to a certain granularity or meets certain conditions, the relevant services subscribed by the service network element to the user data management network element need to be subscribed. [0003] In the current mobile communication system, in the registration process or session establishment process, the service network element initiates r...
