Problems solved by technology

In the AMF disaster recovery scenario, the backup AMF needs to send information about the backup AMF to the SMF. Since the AMF interacts with the SMF through the update session management context message Update SM Context, the related technology will include the backup AMF in the Update SM Context message. However, when the backup AMF does not interact with the SMF through the update session management context message, the backup AMF cannot notify the SMF of the disaster recovery switchover through the update session management context message, which will cause subsequent Business unavailability or discontinuity

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than in the flowchart. The terms "first", "second" and the like in the specification and claims and the above drawings are used to distinguish similar objects, and not necessarily used to describe a specific sequence or sequence.

[0027] At present, in related technologies, since the AMF is the only mobile access point for the terminal, the session information between the terminal (User Equipment, UE) and the session management functio...

Abstract

The embodiment of the invention provides an information processing method, a network element, a computer storage medium and a computer program product, which can send a session update request carrying related information corresponding to a standby AMF to an SMF by the standby AMF when the standby AMF and the SMF do not interact by updating a session management context message in an AMF disaster recovery switching scene. Thus, the SMF completes information updating, and the continuity of subsequent services is ensured.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an information processing method, a network element, a storage medium and a program product. Background technique [0002] In the current system architecture of the fifth generation communication technology (5th Generation, 5G), in order to prevent the Access and Mobility Management Function (AMF) network from being damaged due to equipment failure, power outage, natural disaster, etc. In the event of service interruption, related technologies provide an AMF POOL disaster recovery solution, that is, multiple sets of AMF are deployed in different regions to form an AMF POOL, so that when the current AMF device is unavailable, a backup AMF device is selected from the AMF POOL to take over current business. [0003] Currently, in related technologies, since the AMF is the only mobile access point for the terminal, the session information between the terminal (User Equ...
