Design And Testing Of Telecom Network Integrated Alarm System

Along with telecom reorganization, all the operators face the tough market competition. The differentiation of the market mainstream and the customization of individuals demands have impacted on the traditional telecommunication business seriously. What the operators need to resolve urgently is how to increase operational efficiency, to lower operation and maintenance costs, to improve the service. To the operators, the focus should be shifted from"network-oriented and equipment-oriented"to"business-oriented and client-oriented". Operation and maintenance of back-end should change from emphasizing on variety of specialty and function to the development of comprehensive and centralized maintenance. The back-end should enhance the support to front-end and to customers and cut down response time to changed businesses, thus to improve the operators' service to users. TMN(Telecommunication Management Network) is an international accepted norms;TMN framework has been increasingly adopted in the implementation of network management system. As one of the five functions of TMN, fault management function can reflect the real-time operational status of the entire network through a network of monitoring equipment. When network faults occur, network maintenance staff is able to provide detailed solution to do with abnormal information. It can be said that a good user-friendly alarm monitoring system is a very important component of the integrated alarm system.The author participated in the construction of integrated alarm system of Shanghai Telecom local network. The article covers the design of the system and has four parts:1. Studied the development process of telecommunication network and telecommunication management network. The article introduced the current situation of Shanghai Telecom network and Shanghai Telecom network management system. The author researched the background and target of integrated alarm system of local network.2. Carried on in-depth research and analysis of China Telecom OSS (Operation Support System). The contents include OSS relationships with TMN and NGOSS, OSS function framework and system architecture and integrated alarm system's position in OSS planning. The article introduced other related technologies such as SNMP, alarm correlation and NTP.3. Designed integrated alarm system of Shanghai telecom local network matching the plan of China Telecom OSS: core of the system is event management including functions of alarm collecting, alarm presenting, alarm correlation, resources interface, time synchronization, short message delivering etc. During the whole work, the author paid attention to system scalability and its usability, thus not only making the system to meet the current requirements of business operation, but also laying a good foundation for future extensibility of the system.4. The system's implementation, testing,receiving inspection and application. Finally, the author made an outlook for the further development of integrated alarm system: to collect and analyse operation data more; to create VIP user network management system based on this integrated alarm system.
