七号信令在移动通信故障定位中的应用

The Application of No.7 Signaling in Mobile Communication Fault Location

7号信令是由ITU-T制定的全球电信业的标准。这个标准指定了在通信中各个网络点通过数字信令网交换信息的过程及协议。在以电路交换为基础的GSM网络中,信令流程是一切通信过程的基本。只有确实掌握MS呼叫、位置更新、切换等通信过程中各接口的信令流程,才能有针对性地对网络故障进行分析定位。文中重点分析了GSM网络中位置更新的信令流程,结合信令监测系统获取的有效信令信息,对故障实例进行了分析,建立了一般的故障处理流程。

ITU-T considers No. 7 signaling as the standard of global telecommunications industry. The standard points out the process and the protocol when each net exchange information through digital signaling network in communication progress. In the GSM network which is based on circuit exchange,signaling process is the foundation of all communication. Only when comfily mastering each interface＇s signaling process in communication,such as MS calling,position updating and switching,can we effectively analyze and locate the network fault. This article focuses on the analysis of position updating of signaling process in GMS network. It uses the effective signaling information,which is obtained by signaling monitoring system analyzes the fault instance and establishes a general fault handling process.
