摘要
对TD-SCDMA网络中Iu-PS口基本概念和功能进行了介绍,提出了一种Iu-PS口的监测方案,将Iu-PS口的监测分为解码、合成和统计3大模块。在此基础上分析了Iu-PS口关键协议RANAP协议、GMM协议、SM协议的解码方法,Iu-PS口上的全局CDR和子业务CDR的合成技术以及基于合成的各统计指标的统计方法等,解决了Iu-PS口测试过程中的一些技术难题。本方案已应用到TD-SCDMA网络测试仪和TD-SCDMA监测系统中,通过现网测试,效果良好。
This paper introduces the basic conception and function of Iu-PS interface in TD-SCDMA, and proposes a Iu-PS interface monitor scheme that divides the Iu-PS interface monitor into three modules. Then, the decoding methods for RANAP, GMM, and SM were analyzed. The synthesis technology of overall CDR and sub-service CDR on Iu-PS interface and the statistical method of statistical index based on synthesis were presented to solve the technological problems in the process of Iu-PS interface testing. The solution has been implemented in the TD-SCDMA analyzer and monitoring system and got good results by the real network testing.
