복수 주파수채널을 가진 CDMA 이동통신시스템에서 핸드호프호 제어전략

Abstract

This paper addresses handoff management in a multi-frequency CDMA system with non-uniform traffic loads over cells. We propose a new handoff scheme, called here the adaptive handoff management (AHM), in which the inter-cell hard handoffs, not only incurring equipment cost burden but also degrading call quality, are totally removed. Also contained in the AHM is the call control capability of adaptively reflecting the traffic environment. Traffic and mobility analysis is first conducted on a single isolated cell with two co-centered circle boundaries, thereby rendering two key performance measures, Computational experiments are conducted to illustrate the superiority of AHM in two key performance criteria.
