1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting, to a first base station (BS), a packet data network (PDN) connection request message;
receiving, from the first BS, information on a first network slice selection assistance information (NSSAI), the first NSSAI being selected by a network entity including a packet data network gateway control plane (PGW-C) and a session management function (SMF) from among at least one subscribed NSSAI associated with the UE;
transmitting, to a second BS, a registration request message comprising a requested NSSAI including the first NSSAI; and
receiving, from the second BS, a registration accept message comprising an allowed NSSAI including a second NSSAI mapped to the first NSSAI.
