摘要
BTSM协议监测是全球移动通信系统(global sgstem for mobile communication,GSM)用户在感知系统的基础上,以网络用户感知系统为研究平台,提出了一种Abis口BTSM协议监测方案。介绍了用户感知系统及Abis协议栈结构,在此基础上重点研究BTSM协议解码方案及呼叫详细记录(call detail record,CDR)合成技术,利用方法封装、哈希算法等方法以代码实现了BTSM协议的详细解码、简单解码和CDR流程合成等功能。结合现网数据,将该方案应用于用户感知系统进行测试验证。测试结果表明,结果准确,效果良好。
The BTSM protocol monitoring is the foundation of GSM user perception system.Based on the user perception system,the paper proposes a kind of scheme on realizing BTSM protocol monitoring.Firstly,the paper introduces the user perception system and Abis protocol stack,then focuses on the decoding scheme and CDR synthesis algorithm of BTSM protocol.Using methods encapsulation and hash algorithm the authors implemented the detailed decoding,simple decoding as well as CDR process synthesis according to the programming code.Finally,the scheme was applied to the user perception system for testing.According to the test of network data,it is verified that the test result is correct,and the effect is good.
