Abstract

In this paper, we propose an effective access control scheme based on service characteristics to provide multimedia services such as voice, video and data in broadband CDMA networks. In proposed algorithm, BER characteristics of each service is controlled by different Eb/No, and data traffic is controlled by access probability of data which is determined by activity factor of voice/video traffic. And we perform simulation and analysis of proposed model. As a result, the proposed access scheme shows that the outage probability is decreased by allowing delay of data traffic.

본 논문에서는 광대역 CDMA망에서 음성, 비디오, 데이터와 같은 멀티미디어 서비스를 제공하기 위해서 다양한 서비스 특성에 적합한 액세스 제어 방법을 제안한다. 즉 서비스별로 다른 Eb/No 값을 이용함으로써 서비스의 BER을 조절하고 음성과 비디오의 전송률이 시간에 따라 변하는 특성을 이용하여 데이터의 전송률을 제어하는 방법을 제안하였다. 또한 각 방법에 대한 시뮬레이션과 분석을 수행하였다. 성능 분석결과 제안된 액세스 방법을 사용할 경우 데이터에 대한 지연을 통해 전체적인 outage 발생확률을 감소시킴을 알 수 있었다.
