Abstract

In this paper, a computer simulation approach is proposed to analyze the performance of reverse traffic channels in a base station serving voice and data calls in CDMA cellular systems. It is assumed that multiple traffic channels simultaneously serve a data call and a voice call is served by one traffic channel in a base station. The numerical examples will be presented to derive the capacity of traffic channels from the parameters such as the arrival rates and mean durations of voice and data calls, the soft handoff area ratio, etc..

본 연구에서는 CDMA 이동 통신 시스템에서 음성 호와 데이터 호가 동시에 서비스될 때 기지국의 역방향 트래픽 채널에 대한 용량 분석을 위해 컴퓨터 시뮬레이션을 통한 분석 방법을 제안하고자 한다. 특히 음성 호는 호당 하나의 트래픽 채널을 할당 받지만 데이터 호의 효율적인 서비스를 위해 데이터 호는 호 당 서비스를 위해 필요한 최소 트래픽 채널 개수가 있고 트래픽 채널의 용량이 허용하는 한 어떤 최대 트래픽 채널 개수까지 할당 가능하다고 가정한다. 제안된 시뮬레이션 분석 방법에 따른 계산 결과도 제시될 것이다.
