본 논문은 차세대 광가입자망(XG-PON1)에서 멀티캐스트 데이터의 끊김 없는 서비스가 가능한 핸드오버 기술을제안한다. 이를 위해 기존 이동성 관리 프로토콜인 MIP(Mobile IP), FMIP(Fast MIP), HMIP(Heterogeneous MIP),PMIP(Proxy MIP)을 XG-PON1에 적용할 경우의 장단점을 분석하여 최적의 핸드오버 기술을 도출한다. 또한 멀티캐스트 핸드오버 기법에서 발생되는 터널 컨버젼스 문제점 해결을 위한 방안을 제안하고 분석한다. 본 논문에서제안한 XG-PON1에서 멀티캐스트 지원 핸드오버 기술은 터널 컨버젼스 문제점을 해결하고 핸드오버 지연 및 패킷 전송 코스트를 감소시킨다.
