Title:
METHOD AND DEVICE FOR SUPPORTING MINIMIZATION OF SERVICE DISRUPTION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/240204
Kind Code:
A1
Abstract:
The present disclosure relates to a device and a method for operation of a terminal in a wireless communication system. The method for operation of the terminal may comprise the steps of: receiving a first registration accept message including information related to a disaster public land mobile network (DPLMN) from a first access and mobility management function (AMF) corresponding to a first PLMN; selecting a second PLMN on the basis of the first registration accept message; transmitting a registration request message in which a disaster-related indicator is configured, to a second AMF corresponding to the second PLMN; and receiving a second registration accept message from the second AMF on the basis of the registration request message.
