Abstract
A communication method and an apparatus in a wireless communication system are provided. The communication method includes identifying, by a first satellite including a session management function within a space core network (SCN), a protocol data unit (PDU) session establishment request from a UE, selecting, by the first satellite, a satellite gateway for communicating with a ground gateway, and requesting, by the first satellite, the satellite gateway to allocate a port number which is matched to identification information of a first general packet radio service (GPRS) tunneling protocol-user (GTP-U) tunnel to be used for transmission and reception of packets for a PDU session requested by the UE in a path between a satellite base station which the UE accesses and the satellite gateway, wherein the packets are transmitted or received to and from a terrestrial core network (TCN) by using address information which is converted based on the port number.
