소프트 핸드오프는 주로 사이트 다양성으로 인해 발생하는 많은 이점 때문에 코드 분할 다중 액세스(CDMA) 시스템에 널리 채택됩니다. 그러나 순방향 링크에서는 소프트 핸드오프로 인해 다른 셀 간섭이 증가하여 시스템 용량이 감소할 수 있습니다. 미래 모바일 시스템에서는 인터넷 접속과 같은 모바일 멀티미디어 서비스에서 순방향 링크 부하가 역방향 링크 부하보다 훨씬 높기 때문에 충분한 순방향 링크 용량을 제공하는 것이 매우 중요합니다. 본 논문에서는 음성 서비스는 소프트 핸드오프로 제공되고, 데이터 서비스는 하드 핸드오프로 지원되는 결합 핸드오프 전략을 고려한다. 핸드오프 방법이 순방향 링크 성능에 미치는 영향을 분석합니다. 우리가 사용하는 성능 측정은 비트 에너지 대 잡음 밀도 비율의 중단 확률과 중단 확률에 따른 용량입니다. 결과적으로 우리는 결합된 핸드오프가 음성 및 데이터 서비스를 동시에 지원하는 CDMA 셀룰러 네트워크에서 매우 유용하다는 것을 보여줍니다.

Abstract: The soft handoff is widely adopted in code division multiple access (CDMA) systems for its many advantages mainly resulting from site diversity. However, in the forward link, other cell interference can be increased by soft handoff, decreasing system capacity. In future mobile systems, provision for the sufficient forward link capacity is very important since the forward link load is much higher than the reverse link load in mobile multimedia services such as Internet access. In this paper, we consider a combined handoff strategy in which voice services are provided with soft handoff whereas data services are supported with hard handoff. We analyze the effect of handoff method on the forward link performance. The performance measures we use are the outage probability of the bit energy to noise density ratio and the capacity based on the outage probability. As a result, we show that the combined handoff is very useful in CDMA cellular networks supporting both voice and data services simultaneously.
