통신ㆍ방송간 융합, 음성ㆍ데이터의 통합 그리고 유ㆍ무선이 하나로 통합되는 NGN 환경에서 고부가가치 창출이 가능한 다양한 형태의 서비스 개발과 상용화 노력이 증가하고 있는 상황이다. 또한, 통신/서비스 사업자들은 인터넷 전화, 영상 전화, IPTV 등 신규 서비스 시장 개척을 위한 준비에 박차를 가하고 있다. 발전된 서비스 시장을 위한 노력은 국제 표준화 단체들의 기술 표준화 활동을 통해서도 진행되고 있다. NGN 멀티미디어 서비스(MoIP) 표준화는 ITU-T를 비롯한 ETSI TISPAN과 3GPP 중심으로 진행되어, 현재 다양한 서비스 기술 표준이 제정되어 있다. 본 고에서는 이들 국제 표준화 단체에서 진행중인 멀티미디어 서비스 표준화 동향을 살펴보고자 하며, 또한 국내에서 멀티미디어 서비스 활성화를 위해 추진중인 현황을 소개하고자 한다.
