1. A method for performing communication, performed by a UE (User Equipment), comprising:
transmitting, to an SMF (Session Management Function)+PGW-C (Packet Data Network Gateway-Control), an establishment request message of a PDU (Packet Data Unit) session,
wherein the PDU session is related to a network slice,
wherein the PDU session is related to an interworking procedure,
wherein the SMF+PGW-C is configured with information indicating that the network slice is subject to NSAC (Network Slice Admission control);
receiving, from the SMF, an establishment accept message of the PDU session, based on i) the SMF+PGW transmitting a control request message for the network slice to an NF (Network Function) and ii) the SMF+PGW receiving a response message from the NF,
wherein the response message indicates that the network slice is available.
