1. A method for supporting a non-public network (NPN), by a base station, in a wireless communication system, the method comprising:
transmitting, to an access and mobility management function (AMF), an initial user equipment (UE) message comprising a closed access group (CAG) identifier list supported by a cell accessed by a UE;
receiving, from the AMF, an initial context setup request message comprising access allowance information for CAG cells, wherein the access allowance information of the initial context setup request message comprises an allowed CAG list of the UE and information indicating whether the UE is allowed to access non-CAG cells;
transmitting, to a secondary base station, a secondary base station establishment request message comprising the allowed CAG list of the UE and the information indicating whether the UE is allowed to access non-CAG cells;
determining a target cell based on the access allowance information;
transmitting a handover request message comprising the information indicating whether the UE is allowed to access non-CAG cells to a target base station; and
receiving a handover request response message comprising a handover command message from the target base station.
