摘要
通信设备的协议非一致性问题日趋严重。以我国提出的TD-SCDMA标准为基础,利用SDL提供的TTCN测试工具对终端协议栈GMM层路由更新过程进行测试与仿真,得出仿真的结果消息序列图MSC来介绍3GPP中的协议一致性测试过程。
The problem of the protocol non-conformance in the communication equipments becomes increasingly serious. Based on the TD-SCDMA standard in China, the GMM layer procedures was tested and simulated by SDL and TTCN, and the message sequence chart （MSC） was used to introduce the conformance testing process in 3GPP.
