TD-SCDMA系统MSC间切换若干问题的研究

Research of several problems on inter-MSC handovers in TD-SCDMA system

本文对TD-SCDMA系统中不同MSC间切换发生的问题进行了分析研究,针对DQ-RNC统计的切换请求次数大于HW-MSC统计的切换请求次数,DT-RNC统计的切出成功次数比ASB-MSC统计的少,以及HW-MSC和ASB-MSC在后续切换成功次数不一致等问题,通过信令流程分析,发现了产生问题的原因,并给出了解决办法,可以较好地解决了TD-SCDMA系统的切换问题。

In this paper,the handover problems of TD-SCDMA system between different MSC are analyzed and studied,aimed at the problems that the handover request of DQ-RNC is more than of HW-MSC,the successful handover of DT-RNC is less than of ASB-MSC,and the successful subsequent handover in HW-MSC is not equal to in ASB-MSC and etc,analyzed the signaling process,found the causes of problems,and gives the solution,which can solve the handover problem of TD-SCDMA system better.
