摘　　要：在分析CDMA越区切换的基础上 ,提出了一种改进的双门限软切换方法 ,并对该方法进行了较为详细的理论分析。接着 ,将其与最小逗留时间排队法结合在一起 ,推出混合越区切换方案 ,并与传统的预保护信道方案、最小逗留时间排队方案等进行了性能比较。结果表明 ,所提出的方案具有较好的性能。Based on the analysis of CDMA handoff,a modified two threshold soft handoff method is proposed together with its detailed theorectic analysis,combined with the minimum dwelling time qveung wethed,a mixed handoff scheme is suggested.Performance comparison is conducted with that of conventional guard channel scheme and minimum dwelling time scheme.Results have shown that the proposed scheme is of good performance.
