Document Type and Number:
WIPO Patent Application WO/2023/016331
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of mobile communications, and provides an anchor point determination method, a base station, a terminal, a device, and a computer-readable storage medium. The method comprises: a first base station sends first RRC release information to the terminal, the first RRC release information comprising a mapping relationship between a DRB and a logical channel, a mapping relationship between the logical channel and a logical channel group, or/and a user plane security policy used when the terminal sends a small data packet in an inactive state, so that the terminal determines an anchor point base station when sending the small data packet in the inactive state. The method assists a terminal to configure a reasonable encryption and/or integrity protection configuration while entering an inactive state, avoids the security risk caused by disabling a user plane security function, maintains the consistency of user security understanding between the terminal and a network, and solves the problem of interoperation between the terminal and the network.
