GSMA口信令分析及其在信令分析仪中的应用

Analysis of A-Interface Signal in GSM and Its Application in Signaling Analyzer

对GSM系统信令分析仪中信令关键处理部分进行了论述,并对GSM信令核心部分A接口信令中BSSMAP和DTAP进行了深入分析和研究,给出了BSSMAP和DTAP信令的消息构成,提出了BSSMAP和DTAP解码的一种方法,通过GSM移动信令分析仪在网实际测试表明该方法实用并且信令分析准确。

In this paper,key- processing parts of the signaling in GSM systematic signaling analyzer are dissertated. We focus on deeply analyzing and researching BSSMAP and DTAP, the signaling core of A- interface in GSM sys tem, and present the structure of messages of it. Further more, an access of BSS MAP and DTAP decoding is proposed, and it is testified practical and exact on te st in the GSM system.
