가까운 미래의 방송통신융합기술 서비스는 4G 지상과 위성 시스템이 협력하여 제공 될 것이다. 4G 이동 통신 시스템과 위성 시스템이 공통성을 갖고 서비스를 제공하게 되며, 사용자는 하나의 단말기를 사용하여 각기 다른 네트워크를 통해서 시간과 장소에 구애받지 않고 동일한 서비스를 즐길 수 있다. 유비쿼터스 정보화 시대가 한발 앞으로 더 가까워짐에 따라 본 고에서는 위성을 이용한 개인형 휴대 이동 통신 시스템의 시초격인 GMPCS 및 위성 IMT-2000에 대해 살펴보고, 위성을 이용한 나라별 방송통신융합기술의 동향 및 표준화 동향을 분석한 후, 국내에서 연구중인 IMT-Advanced 위성접속기술과 표준화 개발에 대해 소개한다.
