Abstract

Since 2000, the demand for multimedia content consumption has been continuously increasing. The research and standardization for the mobile broadcast service has been done to deliver multimedia contents to the huge number of users with the minimum cost. A few commercial services started after the related standards were released. We call this mobile broadcast service the 1st generation service. Now, many experts are researching and developing the technologies for 3Screens(TV, PC, and Mobile) Services that an user can enjoy multimedia contents at every place with the various networks and devices. To enable this service, two main technical areas exist. The first is a core network technology that can support the various access network and the second is a common application layer technology. To resolve these technical areas, we propose IMS(IP Multimedia Subsystem) based OMA BCAST(Open Mobile Alliance Mobile Broadcast Service Enabler Suite) as the technical solution for 3 Screen Services in the paper. In addition, we propose application layer multicast that is enable to implement IMS based OMA BCAST to the existing network with the minimum cost. Finally, we show how we can save the implementation cost of IMS based OMA BCAST with the simulation results.

멀티미디어 콘텐츠의 소비가 활발하게 된 2000년 이후, 멀티미디어 콘텐츠의 효율적인 전송을 위해 휴대 방송 기술의 연구가 진행되었고, 관련 표준화의 완료 이후 한국, 일본, 미국, 유럽 등에서 상용 서비스가 시작되었다. 이를 1세대 휴대 방송 서비스라 하며, 현재는 유무선 단말기의 구별 없이 방송 서비스를 제공하는 3Screens(TV, PC, and Mobile)서비스를 위한 연구 및 표준이 진행되고 있다. 3 Screens 서비스를 위한 두 개의 핵심 기술 분야는 다양한 접속망들을 지원할 수 있는 핵심망 기술 및 단일 응용 계층 기술 이다. 본 논문에서는 휴대 방송 응용 계층 표준인 OMA BCAST(Open Mobile Alliance Mobile Broadcast Services Enabler Suite)와 IMS (IP Multimedia Subsystem)를 연동하여 상기 두 개의 핵심 기술 분야를 해결할 수 있는 기술적 제안을 한다. 또한 상기 제안 기술을 최소의 비용으로 현재의 멀티미디어 콘텐츠망에 제공할 수 있는 응용 계층 멀티케스트 방법을 제안하고, 이에 대한 성능 분석을 수행한다.
