DS-CDMA(Direct Sequence-Code Division Multiple Access) 모바일 시스템에서 소프트 핸드오프는 간섭을 줄이고 역방향 링크 용량을 증가시키는 것으로 인식되지만, 무선 채널 자원 관점에서 소프트 핸드오프는 시스템 성능을 크게 저하시킬 수 있다. 본 논문은 DS-CDMA 모바일 시스템의 성능을 평가하기 위해 제한된 현장 환경에서 소프트 핸드오프의 채널 자원을 사용하는 데 중점을 둡니다. 우리의 트래픽 모델은 여러 셀 간에 지역이 겹치는 모바일 트래픽 환경을 기반으로 합니다. 소프트 핸드오프 비율은 모바일의 이동성에 의해 추정되며 시뮬레이션 결과는 트래픽 모델과 잘 일치하는 것으로 나타났습니다. 폐쇄형 솔루션이 없는 소프트 핸드오프 트래픽 모델의 채널 유지 시간 분포는 수치 적분 방법을 통해 도출됩니다. 컴퓨터 시뮬레이션은 비폐쇄형 애플리케이션을 기반으로 유망한 결과를 보여줍니다. 소프트 핸드오프 영역이 차단 확률에 미치는 영향을 알아보기 위해 제안된 트래픽 모델을 사용하여 DS-CDMA 모바일 시스템의 성능을 분석합니다. 그 결과, 주어진 채널로 소프트 핸드오프 영역을 확장하면 핸드오프율과 평균 채널 유지 시간이 모두 증가하여 차단 확률이 크게 증가하는 것으로 나타났다. 이전과 같이 요구되는 차단 확률을 유지하기 위해서는 확장된 영역에 따라 추가적인 채널 자원을 공급해야 합니다. 제안된 트래픽 모델과 본 논문에서 제시된 성능 분석은 실질적으로 수용 가능하다고 우리는 믿는다.

Abstract: In DS-CDMA (Direct Sequence-Code Division Multiple Access) mobile systems, soft handoff is recognized as reducing interference and increasing reverse link capacity, whereas from the radio channel resource viewpoint, soft handoff can make the system performance deteriorate significantly. This paper focuses on using the channel resources of soft handoff in a limited field environment for evaluating the performance of DS-CDMA mobile systems. Our traffic model is based on the mobile traffic environment with region overlap among multiple cells. The soft handoff rates are estimated by the mobility of mobiles, and simulation results show good agreement with the traffic model. The channel holding time distribution of the soft handoff traffic model, which does not have a closed-form solution, is derived by a numerical integration method. Computer simulations show promising results based on the non-closed-form application. We analyze the performance of DS-CDMA mobile systems with the proposed traffic model to see the effect of the soft handoff region on blocking probability. From the result, when the soft handoff region is extended with the given channels, both the handoff rate and the mean channel holding time are increased and these make the blocking probability increase a great deal. To maintain the required blocking probability as before, additional channel resources should be supplied according to the extended region. It is our belief that the proposed traffic model and the performance analysis presented in this paper are practically acceptable.
