Abstract
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by an access and mobility management function (AMF) in a public land mobile network (PLMN) providing disaster roaming service is provided. The method includes determining whether a disaster condition has ended in a previous PLMN associated with a user equipment (UE) which is registered for the disaster roaming service, in response to determining that the disaster condition has ended and the UE has an emergency protocol data unit (PDU) session, generating a message indicating that the UE is registered for emergency service, and transmitting, to the UE, the message.
