1. A satellite in a wireless communication system, the satellite comprising:
a transceiver; and
a processor configured to:
identify a protocol data unit (PDU) session establishment request from a user equipment (UE),
select a satellite gateway for communicating with a ground gateway, and
request, via the transceiver, 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 satellite includes a session management function within a space core network (SCN), and 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.
