Design And Implementation Of Fault Management System In Telecommunications Management Network

Along with the correspondence further development, 3G has already commercially used in more and more many countries and areas. Compare to 2G, 3G communication is much more complex, operating corporation after the scale deployed the 3G network, needs a comprehensive network management system to manage these equipment. This comprehensive network management system usually uses for the maintenance of these equipment. At the same time, the TMN also provides some service, for example: Cost function and so on. In here, the main is to introduce the fault management function which does correlate to the system of work state.TMN is the technology which does profit from the OSI by ITU-T, defines the network architecture as the management telecommunication service. TMN based on the concept of OSI system, and has developed in the application of telecommunication. It causes the network management system and the telecommunication network under the standard architecture, according to standard connection and standard information form exchange management information, thus make the function of network management come true. One of TMN basic principles is to separate the management function and the telecommunication function. The network administrator can manage this equipment which distributes in the different level of node. The goal of TMN is to provide group of standard interface, to make the management of the network and operate the equipment easily. TMN proposed is to a great extent in order to satisfy the connective request among the various part of network. The central management and distributional processing are the TMN prominent characteristics.Base on the real analysis of a case, unified an already commercial telecommunication network management system to introduce the fault management. This set of system provides performance management, disposition management, fault management which belong to TMN. The fault management is a very important function of TMN, which is mainly through observes and analyzes the condition of various net unit and accurately discovered the fault promptly in the network, at the same time, it also provides the function of to diagnosis the board. Generally speaking, the fault management may divide into the alarm management and diagnose management. The alarm management provides a convenience direct-viewing method to collect the base-station system running station, which is show by forms of writing, graph, sound, light and so on, in order to guarantee the base-station system running normally. The diagnosis test has integrity characteristic of initiative, custom-made, the sense of purpose, which can help the user to understand the system run state in detail, is a an indispensable part of the network management system, is a powerful guarantee of which the system run stable.
