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.

Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. The present disclosure can be applied to an intelligent service (e.g. a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, a retail business, a security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure provides a method wherein, after a MICO mode terminal establishes a connection and transmits data, the MICO mode terminal can be kept in a connected mode state, rather than entering an idle mode, in order to provide for a case where slightly delayed response traffic occurs according to the type of application or service.
