The present disclosure is based on 5G communication technology and IoT related technology and can be applied to intelligent services (e.g., smart home, smart building, smart city, smart or connected car, health care, digital education, retail business, security, and safety related services). A method is provided that enables the terminal and the 5G network to check each other's capability information to achieve interworking between network slices defined differently by different mobile network operators. The method includes receiving system information associated with a network slice; transmitting, to an access and mobility management function (AMF) entity of a visited public land mobile network (VPLMN), a first message, in case that the system information is associated with a base station corresponding to the VPLMN; and receiving, from the AMF entity, a second message including allowed network slice selection assistance information (NSSAI) for the terminal.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.Methods and apparatuses provide a service to user equipment through a dedicated core network. In one method, a base station, also referred to as eNB, receives a non-access stratum (NAS) message from user equipment (UE), and transmits a first initial UE message having the NAS message to a first mobility management entity (MME). Also, the base station receives a redirection request message having the NAS message from the first MME, and transmits a second initial UE message having the NAS message to a second MME. In another method, the MME receives the first initial UE message having the NAS message from the base station, and transmits the redirection request message having the NAS message when the MME fails to support a dedicated core network according to UE usage type information. If the redirection request message is transmitted, a second initial UE message having the NAS message is transmitted to a dedicated MME.
