TD-SCDMA终端CC实体一致性仿真测试

Consistency Simulation Test of CC Entity Terminal in TD-SCDMA

CC实体是无线协议栈L3层中连接管理(CM)子层中的独立功能实体,其主要功能是对用户之间的呼叫进行控制,包括呼叫建立、呼叫释放以及呼叫重建等。本文利用SDL工具提供的TTCN测试工具在基于3GPP TS34123_1_s10条件下对移动台主叫过程进行了仿真。通过比较仿真的结果——消息序列图(MSC)与设计的MSC来分析设计的可靠性。

Entity of CC is the independent function entity in conjunction manage（CM） layer which consists in wireless protocol L3. Its main function carries on the control to the call sign between customers, including the establishment of the call, the release of call and the rebuild of call etc... For the mobile originating all establishment procedure, the test and simulation proedure are carried out by the TTCN tool which is provided by the SDL on the basis of 3GPP TS34123-1-s 10. And we analyze the dependability of the design comparing the MSC charts created automatically by the TTCN and the designed MSC charts call control.
