METHOD FOR PERFORMING REGISTRATION-RELATED AMF PROCEDURE BY UDM IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR Russian patent published in 2020 - IPC H04W60/00 

FIELD: physics.

SUBSTANCE: invention relates to a wireless communication system and is intended to enable unified data management (UDM). Invention describes, in particular, a method for enabling UDM in order to perform a registration-related AMF procedure in a wireless communication system and comprises steps of: receiving, by UDM, a message associated with registration of a serving AMF UE, which includes access type information and identification (ID) information, from a first AMF; transmission, by UDM, associated with registration of a message into a second AMF, when a second AMF exists, wherein the second AMF is registered as a serving AMF UE and associated with access type information.

EFFECT: technical result consists in improvement of efficiency of registration of access and mobility management (AMF) function in 5G-system of mobile communication.
