selecting a first standalone non-public network (SNPN) to be accessed based on information on the SNPN, the information being broadcasted from a base station;
transmitting, to a network entity of the first SNPN, a registration request message for accessing the selected first SNPN;
transmitting, to the network entity, a packet data unit (PDU) session request message to request establishment of a PDU session with the first SNPN;
receiving, from the network entity, SNPN subscription data including a subscription credential of the terminal for a second SNPN through the PDU session established in response to the PDU session request message;
releasing registration with the first SNPN;
selecting the second SNPN to be accessed based on the received SNPN subscription data; and
performing authentication on the second SNPN based on the subscription credential to be registered with the second SNPN.
