Abstract

The invention provides a data management method, device and system, equipment and a storage medium, and relates to the field of communication. The method is applied to a first node in a UDM system, and comprises the following steps: acquiring authentication information of a first user; broadcasting authentication information of the first user; receiving first information sent by at least one second node; the second node is a node except the first node in the plurality of edge nodes or a central node; the first information is generated after the second node verifies whether the first user is an effective registered user according to the authentication information of the first user and the registration information of the first user stored in the second node; the first information is used for indicating whether the authentication information of the first user passes the verification of the second node; and determining an authentication result of the first user according to the proportion of the first information indicating to pass the verification of the second node in all the first information and a preset first proportion. The method is suitable for the authentication process and is used for improving the security of the UDM system.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data management method, device, equipment, storage medium and system. Background technique [0002] The unified data management (UDM) network element is one of the network elements in the fifth generation mobile communication technology (5th generation mobile communication technology, 5G) core network. UDM network elements can be used to store user subscription data and authentication. For example, the UDM network element may obtain the authentication information sent by the user equipment, and when the authentication information sent by the user equipment is the same as the registration information pre-stored in the UDM network element, the UDM network element may determine that the user equipment passes the authentication. After passing the authentication, the UDM network element can provide services for the user according to the service information in the user's subs...
