Abstract

The invention provides a terminal UE registration method, device and equipment. Under 5G core network slice isolation networking, when an AMF finds that UE is unsuccessfully registered to the AMF sent by a 5G base station, a Registration reject message at least carrying a first cell and a second cell is sent to the UE. Therefore, when the UE carries out information registration again, the UE selects the target network slice information based on the configured network slice in the first cell, and when the 5G base station receives the registration information sent by the UE, the corresponding target AMF is determined according to the target network slice information in the Requested NSSAI information, so that the correct AMF is selected, and the UE successfully registers to the target AMF. Therefore, the migration method provided by the embodiment of the invention is applied to solve the problem that the UE cannot be registered normally due to the AMF redistribution process based on the RAN under the 5G core network slice isolation networking.

Description

technical field [0001] The present application relates to the field of 5G network technology, and in particular to a terminal UE registration method, device and equipment. Background technique [0002] 5G network communication technology is one of the most advanced network communication technologies in the world. Compared with the widely used 4G network communication technology, 5G network communication technology has a very obvious advantage in transmission speed, and the improvement in transmission speed is very advantageous in practical applications, so the application of 5G network communication technology in today's play an increasingly important role in social development. [0003] However, in practical applications, in the networking scenario where the UE (User Equipment, terminal) is located under the isolation of 5G network slices, when the UE moves from the coverage area of ​​the original 5G base station to the coverage area of ​​the next 5G base station, the UE d...
