1. A method performed by a central unit (CU) in a wireless communication system, the method comprising:
receiving, from a distribution unit (DU), information regarding whether to allow a manual closed access group (CAG) selection on a CAG identifier (ID) not included in a list of allowed CAG IDs of a wireless device for each of public land mobile networks (PLMNs);
receiving, from an access and mobility management function (AMF), a list of PLMNs supported by the AMF;
determining CAG control information regarding at least one PLMN for which a manual CAG selection on a CAG ID not included in the list of allowed CAG IDs of the wireless device is allowed, based on the list of PLMNs supported by the AMF and the information received from the DU; and
transmitting, to the DU, the CAG control information.
