1. A communication method performed by a user equipment (UE) to receive a paging message, the communication method comprising:
registering to a stand-alone non-public network (SNPN);
transmitting, to a session management function (SMF) of the SNPN or an access and mobility management function (AMF) of the SNPN, a protocol data unit (PDU) session establishment request message for requesting subscription to a notification service for receiving a paging message of a public land mobile network (PLMN);
registering to the PLMN through the SNPN and a non-3GPP inter-working function (N3IWF) of the PLMN;
in a case where a paging event occurs when the UE is in an idle state in the PLMN, receiving the paging message from the AMF of the SNPN having received a notification message based on the notification service; and
performing a service request procedure based on the paging message.
