[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. Such as image 3 As shown, in the process of the service network element subscribing to the UDM network element in the registration process initiated by the terminal (UE), 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 ; Based on the registration request message carrying the first subscription context information, the UDM network element feeds back a registration request response message to the AMF network element, 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 can obtain the subscription data from the UDM network element ac...

[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. Such as 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 A request message, and carries the first subscription context information used to indicate the subscription requirement; based on the subscription data request message carrying the first subscription context information, the UDM network element feeds back the subscription data request response message to the AMF network element, and carries in it The second subscription context information identifies a subscription result.

[0095] In this embodiment, the service network element is an SMF network element, and the user data management network element is a UDM network element. Such as Figure 5 As shown, in the process of the service network element subscribing to the UDM network element in the session establishment process initiated by the terminal (UE), the AMF network element creates a session management context with the SMF network element according to the normal process; then, the SMF network element sends the UDM network element The network element sends the subscription data request message, and carries 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 SMF network element based on the subscription data request message carrying the first subscription context information , and carries the second subscription context information therein, identifying the subscription re...

Abstract

Provided in an embodiment of the present invention are a subscription method, a serving network element and a user data management network element, the method comprising: sending a first request message to the user data management network element, the first request message being a registration request message or a subscription data request message, and the first request message carrying first subscription context information, to indicate a subscription demand; receiving a first response message fed back by the user data management network element based on the first request message, wherein the first response message is a registration request response message or a subscription data request response message, and the first response message carries second subscription context information, and indicates a subscription result corresponding to the subscription request. According to the embodiment of the invention, the number of signaling interactions in a registration or session establishment process is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, 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 the network or establishes a session, the service network element needs to register with the unified data management network element (Unified Data Manager, user data management network element) to obtain contract data and subscribe to related services; and the terminal goes to register 1. When the session is released or the released session belongs to a certain granularity or meets a certain condition, the service network element needs to subscribe to the related services subscribed to the user data management network element. [0003] In the current mobile communication system, in the registration process or session establishment process, the service network element initiates the...
