Abstract
A network slice interworking method includes receiving a network slice information request from a user equipment (UE), identifying network slice subscription information of the UE, verifying whether the network slice subscription information matches pre-stored network slice selection assistance information (NSSAI), transmitting network slice information including the pre-stored NSSAI to the UE when the network slice subscription information matches the pre-stored NSSAI, transmitting a network slice selection request to a network slice selection function (NSSF) when the network slice subscription information does not match the pre-stored NSSAI, receiving a network slice selection result in response to the network slice selection request, and transmitting network slice information including the received network slice selection result to the UE.
