Abstract

This paper proposes a method for providing the information about multimedia streams for telepresence services to heterogeneous services such as IMS (IP Multimedia Subsystem) and RTCWeb (Real-Time Communication in WEB-browsers). First of all, we design an interworking gateway for each service and suggest a procedure for providing the information about multimedia streams, which is defined by CLUE, a working group for standardization, to the heterogeneous services. We also apply the method of the actual CLUE information exchange and implement it in our experiment environment. Finally, we show that the proposed method can exchange more information than previous methods even though the media session re-establishment time is similar to legacy systems in terms of performance analysis. With the proposed method, the heterogeneous services can collect a variety of information about the telepresence service and use it according to user preference. In this way it provides rich multimedia streaming services for many areas.

본 논문은 텔레프레즌스 서비스의 멀티미디어 스트림 정보를 IMS(IP Multimedia Subsystem)와 RTCWeb(Real-Time Communication in WEB-browsers)과 같은 이종 서비스에 제공하기 위한 방법을 제안한다. 먼저 각 서비스를 연동하기 위한 게이트웨이를 설계하고, 텔레프레즌스를 위한 표준화 워킹그룹 CLUE에서 정의하는 멀티미디어 스트림 정보를 이종 서비스에 제공하는 절차를 제시한다. 또한 실제 CLUE 정보 교환 방법을 적용하고 실험 환경을 구현하여 성능 분석 수행하였고, 기존의 미디어세션 재설립 방법과 비교하여 지연시간은 크게 증가하지 않으면서 많은 정보를 교환할 수 있음을 보였다. 제안된 방법을 통하여 기존의 이종 서비스 단말에서는 텔레프레즌스 서비스의 다양한 정보를 수집할 수 있고, 사용자 기호에 따라 적절하게 적용할 수 있으며, 다양한 영역에서 응용하여 풍부한 멀티미디어 스트림 서비스를 제공할 수 있다.
