摘要
,是移动通信诞生以来中国首个拥有自主知识产权的标准。它得到了国内外众多通信巨头的大力支持,。,,测试任务相当繁重而紧张。文章正是产生于这样的背景下,,再到测试验证的完整开发过程。
首先,介绍了协议测试相关理论,为协议测试提供了理论依据。其次,对 ,着重分析了RRC连接模式下的几个重点过程。然后,介绍RRC实体的具体实现。包括基于有限状机对状态进行了划分、定义连接模式下各个状态之间的转移以及使用SDL与C代码相结合的方法对RRC进行具体实现。
最后,板级测试。作者结合多年的 ,针对协议栈软件开发后期的需求,和 SDL协仿真测试方法进行了改进,的板级测试方法,并对 。通过对测试得出的MSC图的详细分析,把实际测试结果中的状态转移、MSC 图中的信号流程、消息交互以及数据流等与预期的情况进行比较。验证了原因为无线链路失败的小区更新过程设计的正确性,也定位出在无线承载重配置的设计过程中存在的故障点,板级测试方法的有效性。

Abstract
As one of the three main international standards for the third generation munication,TD—SCDMA is the first standard of China with autonomous intellectual is vigorously supported by both内rd盟and munication giants. Presently,TD—SCDMA indus缸'y chain has already been established in ·mercial is just around the corllel')Industrial development has entered the final attack stage of the l'eseltreh)and the testing task has been quite Ollerous and paper is based 011 such a background,it exposits the development process of RRC from the analysis to the realization and the certification lastly.
Firstly,it introduces the correlated theories about protocol test,which provide a theoretical basis for the protocol ,it gives a detailed analysis Oil the protocol of RRC,it mainly analyzes the reeonfiguration,cell update and ,it introduces the realization about RRC,including the division of state,the transfer of state under eormection and using SDL and C code to realise RRC.
Finally,it focuses on the board-level test based on for to the demand ofthe later bined with the author’s many years ofTD—SCDMA terminal protocol stack testing ex
