Abstract

본 발명은 모바일 멀티캐스트 시스템 및 그 방법에 관한 것으로, 특히 네트워크 기반의 모바일 멀티캐스트 시스템 및 그 방법에 관한 것이다. 본 발명의 일 실시 예에 따른 시스템은, 네트워크 기반 이동성을 지원하는 모바일 멀티캐스트 시스템으로, 액세스 망 내에 이동 단말들과 무선 채널로 통신하며 단말의 2계층 주소를 획득하여 제공하는 액세스 포인트들과, 상기 액세스 포인트에 포함된 각 단말의 핸드오버를 제어하고, 단말로 제공할 멀티캐스트 패킷을 상기 단말로 전송하며 상기 각 액세스 포인트에 대응하여 구비된 관리부들과, 네트워크를 통해 멀티캐스트 데이터를 수신하고, 상기 멀티캐스트 데이터의 수신을 원하는 단말로 상기 멀티캐스트 패킷을 전송하는 라우터와, 상기 관리부들로부터 단말의 위치 정보를 획득하고, 상기 라우터로부터 멀티캐스트 데이터의 수신 여부 질의 메시지 수신 시 상기 각 관리부들로 상기 질의 메시지를 전송하여 단말의 멀티캐스트 가입 여부를 확인한 후 멀티캐스트 가입을 위한 맴버쉽 보고 메시지가 수신되면 상기 라우터와 상기 맴버쉽 보고 메시지를 송신한 관리부간 터널을 설정하도록 제어하는 이동성 제어 서버를 포함한다.
