Mobile network systems have become more complex, especially large-scale mobile networks. Therefore, the performance of the NMS (network management system) becomes a challenge to software integration vendors. We summarize the problems encountered in our previous development of a large-scale mobile network management system. These problems can be mainly classified into two aspects: the interface between NMS and managed objects, that include not only network elements, but also the vendor EMS (element management system); the management data process pattern. To solve the first problem, a model driven mechanism is proposed. To solve the second problem, we suggest a loose coupling mode for the three main function sets (CM, PM and FM), which meets the requirement of a large-scale mobile network NMS better. We adopt the above two approaches in our real NMS which can manage 2G, 2.5G and 3G mobile networks. The results demonstrate that the two approaches can solve all problems analyzed at the beginning of the paper.
