摘　　要：对TD—SCDMA网络的Iu—PS口信令信息及业务流程进行了分析研究，提出一个在Iu—PS口上实现呼叫追踪与业务分析相分离的主从CDR合成方案。阐述了该CDR合成的原理及算法，开辟了一种采用Hash动态合成的实现方法，解决了Iu—PS口CDR的合成效率低下问题。该方案已经应用到TD—SCDMA集中监测系统中，通过现网测试，效果良好。The signaling information and business processes of the Iu-PS interface in the TD-SCD- MA network are analysed. A primary and secondary CDR synthesis program is put forward by which call tracing and business analysis are separated. The principle and algorithm of CDR synthesis are introduced and a hash dynamic synthesis method is opened up to solve the problem of low efficience in getting CDR in Iu- PS interface. The solution has been implemented in the TD- SCDMA focus monitoring system and good results are obtained by the real network testing.
