Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communication technology, and in particular to a user data synchronization method, a UDM, and a computer-readable storage medium. Background Art

[0002] Currently, industry customers have increasingly higher requirements for the security and isolation of production data, and require that the operation of downlink network elements should not be affected by long-distance transmission interruptions, link failures, and upgrades of public network (also known as large network) network elements. Therefore, the current downlink customer-side private network usually includes emergency UDM (Unified Data Management) (also known as private network UDM or local UDM or campus UDM), which synchronizes data with the operator's UDM (i.e., public network UDM) to achieve emergency access capabilities for local data services when the public network fails or the connection is interrupted.

[0003] From the perspective of operators, it is hoped that the user card issuance and control rights belong to the operator and are subordinate to the public network UDM, that is, user data is mainly contracted with the public network to reduce the risk of the operator being bypassed. However, from the perspective of industry customers, for the sake of industry security, it is hoped that when private network users access, authentication and business data are carried by local network elements, and card opening and number release can be uniformly planned and executed by the operator.
