摘　　要：介绍了SM协议及GPRS网络测试仪中SM协议监测模块的基本概念和功能。监测功能包括消息解析、核心参数提取、利用关键参数进行呼叫合成及对合成结果进行统计分析处理4个环节。其中消息的解析又包含消息数据详细解析与合成信息数据提取解析2个部分,故需要重点说明SM协议监测模块消息结构,并在此基础上研究SM协议的详细解码和基础解码、CDR合成技术、实时统计分析等。现场测试保证了数据的真实性和相关理论方法的有效可行性。Paper mainly gives a detail analysis and research on the basic conception of test module of SM protocol in GPRS Tester. On the basis of the testing procedure of this protocol, the PDU decoding, the CDR synthesis method of messages and statistic technology, is presented. The message decoding is an important part of the test function, and it contains detail message decoding and keyword information decoding. It is important to describe the message structure, which provide a foundation of the research for decoding, CDR synthesis, realtime statistics. The validity of the data and the feasibility of the theories were confirmed by actual testing.
