摘要
介绍了 GSM移动信令网中移动应用部分 ( MAP)的监测问题 ,主要讨论了 MAP分层结构 ,MAP信令协议分析及移动业务分析。针对 MAP的分层格式 ,着重介绍了其由事务处理能力层 ( TCAP)向 MAP层的解码过程 ,给出了流程图 ,并结合实例分析了解码结果。在建立在底层解码的基础上的移动分析中 ,给出了包括呼叫建立号码 ,统计及呼叫故障统计的实现过程实测情况。 MAP信令监测系统的实现对更好地维护管理 GSM信令网 ,优化 GSM网络提高网络的运行质量都是不可缺少的。实测结果对
In this paper, the monitoring problem for the Mobile Application Part(MAP)in GSM mobile signaling network is presented,and the MAP layered structure,MAP signaling protocol analyzing and mobile services analyzing are mainly discussed. In view of the MAP layered formation, the decoding process from the Transaction Capabilities Application Part(TCAP) to MAP layered is emphasized, the flow chart is given and the decoding results combined with practical examples are analyzed. In the mobile service analyzing based on the bottom layer decoding, the realizing way and the practical monitoring for call set-up number and call fault statistics are involved. It is indispensible for MAP signaling monitoring system to realize better maintaining and managing the GSM signaling network, optimizing the GSM network and enhancing the operation quality in the GSM network.The practical monitoring is helpful in MAP signaling monitoring system.
