摘要：

为实现对LTE网络中SlAP的监测，在介绍LTE网络测试仪软件平台设计方案的基础上，针对国内外现有网络协议监测技术中协议解码、呼叫记录（call data record,CDR）合成研究方案的时效性的不足，设计了SlAP监测模块的实现方案。该方案采用定义和实现相分离的方法进行消息解码，提高了代码的独立性和可移植性，使用散列索引和超时管理机制进行SlAP消息合成，保证了合成的准确性和有效性。本文方案已成功应用于LTE网络测试仪中，使用仿真数据进行测试，效果良好。

Abstract:

For realizing SlAP monitor in LTE network, the implementation scheme of SlAP protocol monitoring module was designed to cope with the insufficiency of protocol decoding and CDR synthesis research scheme effetiveness, on the base of introducing LTE network monitor software platform. The scheme adopted the thought of separating definition and realization for message decoding, improving the code independence and portability. The use of Hash index and overtime management mechanism of SlAP message synthesis ensured the accuracy and validity of synthesis. The scheme had been successfully applied to LTE network monitor. It has been proved to have a good effect by simulation data for testing.

Key words: LTE, SlAP, protocol monitor, Hash index
