Claim 11:
12. A network entity of a first standalone non-public network (SNPN) for a mobile communication system, the network entity comprising:
a transceiver configured to transmit and receive signals; and
a controller coupled with the transceiver and configured to:
receive, from a terminal, a registration request message for accessing the first SNPN,
complete registration of the terminal based on the registration request message,
receive, from the terminal, a packet data unit (PDU) session request message to request establishment of a PDU session with the first SNPN,
establish the PDU session in response to the PDU session request message,
transmit, to the terminal, 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, and
release the registration of the terminal,
wherein the terminal selects the first SNPN to be accessed based on information on the first SNPN, which is broadcasted from a base station of the first SNPN, and
wherein the terminal selects the second SNPN to be accessed based on the SNPN subscription data transmitted to the terminal and is registered with the second SNPN by performing authentication on the second SNPN based on the subscription credential.
