12 Claims

1. A method performed by a base station in a wireless communication system, the method comprising:

transmitting, to an access and mobility management function (AMF) entity, requested network slice selection assistance information (NSSAI) including at least one single-NSSAI (S-NSSAI) not available in at least one first cell associated with a terminal;

receiving, from the AMF entity, a radio access technology/frequency selection priority (RFSP) index associated with the at least one S-NSSAI not available in the at least one first cell;

identifying information associated with redirection of the terminal to at least one second cell supporting the at least one S-NSSAI, based on the RFSP index; and

transmitting, to the terminal, a radio resource control (RRC) message including the information associated with the redirection,

wherein the at least one first cell is associated with a current location of the terminal.
