信令分析与TD-SCDMA网络优化

-SCDMA is one of the major 3G systems, and TD-SCDMA network is being deployed in China .However it is still in commercial trial period, which means there are lots of jobs for the network optimization, and these jobs are essential to the performance of TD-SCDMA .In this paper, we discuss the important role that signaling analysis could play in the process of TD-SCDMA network optimization .and we point out Iub interface is a suitable interface to collect signaling data .Then we explain how to calculate KPI by counting protocol information and introduce a KPI assessment system for TD-SCDMA .Finally ,we discuss how to apply signaling analysis to solve network problems in detail .
