METHOD AND DEVICE FOR SUPPORTING COMMUNICATION BY USING SATELLITE IN WIRELESS COMMUNICATION SYSTEM

The disclosure provides a method of supporting communication by using a satellite in a wireless communication system including transmitting, by a user equipment (UE), a registration request message for accessing a public land mobile network (PLMN) to an access and mobility management function (AMF) through a satellite radio access network (RAN), receiving, by the UE, a registration reject message from the AMF through the satellite RAN in response to the transmitted registration request message, and storing the PLMN in a PLMN list not allowed in a current location of the UE based on a cause value included in the received registration reject message.
