Design And Implementation Of 3G Telecom Network Management System Based On TMN

With the high-speed development of telecom-communication technology and with the maturity and commercialization of 3G, the scale of cellular network is becoming more and more larger; the structure of the network is changing constantly, and the complexity of the network is being improved day by day. Thus the maintenance task is becoming more and more important. To insure that the network is working under a high-efficient status, and the data of network enviroment is collected timely, and also improving the efficiency and shorten repairment cycle, it is needed to develop an advanced network management system urgently.It's a quite immportant subject to study the management function requirement of 3G network management system and realize such a system. The main research work of this paper includes:1. Explore the current telecom network and drew a conclusion that it's immportant to develop a 3G network management system with multiple functions and good compatibility.2. Study TMN model explictly; by adopting the model, the network management system can inter-operate with other management systems.3. Make a plan for 3G network management systems according to the characteristic of 3G and confirm the management functions of 3G-network management system should possess, and present a scheme of realization. Some key technologies are also explored.4. Analyse the software management functions and its service flow, and present a realization.5. Put forward the further developing direction of the network management system.The network management system the paper shows has been realized and commercialized by one known telecom company with good operation status. The innovations of this work are embodied in:1. By adopting CORBA middle middleware technology, it realized a distributed, extendible and high-efficient network element management system.2. By adopting Manager/Agent structure, combining with XML technology, it desighed a flexibly and expandability network element dynamical access scheme.3. It provides a designation about how to realize the transmission function based on FTP protocol and remote operation based on MML.
