Title:
METHOD AND DEVICE FOR UPDATING LOCATION OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/158928
Kind Code:
A1
Abstract:
The present disclosure relates to a method for updating the location of a terminal in a wireless communication system, the method comprising the steps in which the terminal: registers itself in a 5G system (5GS) through a non-3GPP access; transitions to an idle state for the non-3GPP access; and performs a service request procedure for transitioning from the idle state to a connected state for the non-3GPP access, wherein, when the terminal is registering in the 5GS through the non-3GPP access, the tracking area identification (TAI) for the registration area (RA) of the context of the terminal is set as first TAI, and the service request procedure can be performed on the basis of second TAI.
