Abstract
최근 디지털 정보통신 기술의 발전으로 네트워크 기술 및 성능의 적용 범위가 모든 분야로 확대됨에 따라 모든 정보단말, 가전기기, 사물 등이 하나의 네트워크로 연결되는 차세대 통신환경으로 진화되고 있다. 이러한 차세대 통신 환경에서의 핵심기술인 IMS(IP Multimedia Subsystem) 기반 네트워크에서 원활한 통합서비스(convergence service)의 제공을 위해서는 사용하던 정보단말이 바뀌거나 네트워크가 변화하더라도 이용 받던 서비스들을 그대로 제공 받을 수 있는 끊김없는(seamless) 서비스가 가능하여야 한다. 본 논문은 IMS Enabler를 통한 통합 서비스 제공환경에서 사용자의 네트워크 환경의 변화나 정보단말의 변화에도 끊김없는 서비스를 제공하기 위한 세션제어기법과 그 구조를 제안하고 그에 따른 서비스 세션 제어 프로토콜(Service Session Control Protocol : SSCP)을 제시한다.
