The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present subject matter refers to a method for a user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system is provided. The method includes registering to a public land mobile network (PLMN) on both of a 3rd generation partnership project (3GPP) access network and a non-3GPP access network, receiving, from an access and mobility management function (AMF), a message while the 3GPP access network is in an idle state, in case that the message is received over the 3GPP access network, identifying the message is related to a voice service and in case that the message is received over the non-3GPP access network, identifying that the message is related to a non-voice service.

Method and system to determine service in incoming message

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.
