Abstract: A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes transmitting, to an access and mobility function (AMF), a registration request message for moving to a first public land mobile network (PLMN) from a second PLMN, receiving, from the AMF, a registration accept message including first single-network slice selection assistance information (S-NSSAI) corresponding to the first PLMN of the AMF, determining whether second S-NSSAI associated with a protocol data unit (PDU) session established for the UE matches to the first S-NSSAI, wherein the second S-NSSAI corresponds to the second PLMN, and locally updating the PDU session based on a result of the determining.
