Zusammenfassung:The present invention discloses a method and apparatus for supporting a communication service between mobile communication terminals. A serving gateway according to an aspect of the present invention includes a terminal information storage part for storing the information of user terminals included in connection response messages received from a packet data network gateway in a storage; a packet analysis part for analyzing the destination IP address of an IP packet using the information of user terminals stored in the storage when receiving the IP packet from a first user terminal; and a packet transmission part for transmitting the IP packet to a second user terminal or a packet data network gateway according to the analysis result of the packet analysis part. It is possible to reduce the load of the packet data network gateway. 본 발명은 이동 통신 단말 간 통신 서비스를 지원하는 방법 및 장치를 개시한다. 본 발명의 일 측면에 따른 서빙 게이트웨이는, 패킷 데이터 네트워크 게이트웨이로부터 수신되는 접속 응답 메시지들에 포함된 사용자 단말들의 정보를 저장소에 저장하는 단말 정보 저장부; 제 1 사용자 단말로부터 IP 패킷 수신시, 상기 저장소에 저장된 사용자 단말들의 정보를 이용하여 상기 IP 패킷의 목적지 IP 주소를 분석하는 패킷 분석부; 및 상기 패킷 분석부가 분석한 결과에 따라 상기 IP 패킷을 제 2 사용자 단말 또는 패킷 데이터 네트워크 게이트웨이로 전송하는 패킷 전송부;를 포함한다.
