Abstract
Provided are a communication method and system that combine the 5G communication system with IoT technology to support a data rate higher than that of the 4G system. 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 for providing network slice information of a visited public land mobile network (VPLMN) in a wireless communication system includes generating mapping information by mapping first slice information for a visited public land mobile network (HPLMN) of a user equipment (UE) and second slice information for the VPLMN connected to the UE when roaming, and transmitting, to the UE, information corresponding to a slice requested by the UE, the information selected based on the mapping information.
