Abstract

Recently, WiBro has been developed to efficiently support real-time broadcasting with wireless system. MBS (Multicast Broadcast Service) based on WiBro has numerous applications such as DMB. Since the current MBS uses only common channel managed by scheduling, it cannot effectively support many users at the same time. This paper proposes a new counting scheme with which the channel mode can be properly switched between common channel and dedicated channel. It thus allows efficient use of limited radio resource in WiBro for the MBS.

최근에 들어서 WiBro는 무선상에서 효과적인 실시간 방송을 지원하기 위해 개발되어 가고 있으며, WiBro상에서 MBS (Multicast Broadcast Service)는 DMB와 같은 다양한 애플리케이션들을 제공하고 있다. 하지만 현재의 MBS는 스케줄 방식인 공용채널만을 사용하기 때문에 다수의 사용들을 동시에 효과적으로 수용 할 수 없게 된다. 그러므로 본고에서는 채널 모드를 공용채널과 공용채널을 알맞게 전환할 수 있는 새로운 카운팅 기법(counting scheme)을 제안한다. 따라서 제안한 카운팅 기법은 WiBro상에서 MBS통해 무선 자원을 효과적으로 할당할 수 있도록 한다.
