IMS网络信令流程的可视化展现及故障分析技术研究

介绍了信令可视化展现工具的研制方法:通过抓取IMS网络呼叫会话建立过程中的各网元产生的实时信令数据,再通过解析算法,将信令数据包转换为图形化信令流程图;介绍了运维人员通过查询呼叫会话的流程图可方便直观的了解IMS网络的呼叫状况,尤其是在呼叫出现故障的环节采用描述性文字描述故障原因,而不是故障代码;还介绍了一种故障分析的方法:借助信令可视化工具,结合故障自助申报、故障例测计划编排及故障分析等模块,实现通信网络故障前、中、后的三维全景覆盖。借助这两个方法的帮助,运维人员可及时掌握通信网络的运行状况,提高运维水平,减轻运维压力,增加IMS系统安全可靠性。

This report introduces the development method of signaling visualization tools： real-time signaling data generated by crawling IMS network call each element in the process of establishing a session, and then through analysis algorithm, the signaling data packet switching of signaling flow chart for graphics. Call to know the condition of IMS network conveniently call session through the query process can be the operation and maintenance personnel, especially the use of descriptive text to describe the reasons for failure in the failure of the link, rather than the fault code. In addition, the report also introduces the method of analysis of a fault by means of signaling visualization tools, combined with the fault self declaration, fault test cases and fault analysis of the layout plan module, realize the communication network fault panorama before and after covering. With the help of these two methods, operation and maintenance personnel to master the operation of the communication network in a timely manner to improve the level of operation and maintenance, reduce operating pressure, increase the reliability of IMS system security.
