Element Mediator Function Design in the TMN

With the expansion of the scale of the communication network, the constant introduction of new business as well as the use of mobile network equipment from different hardware manufacturers, networks become larger and more complex, the device shows diversification, which makes the network management of the entire mobile communication network extremely complex. A complete set of advanced communications network management system to effectively manage a variety of physical devices and logical resources is particularly important. Based on TMN basic theory analysis of the network management function model, the intermediary function in the system model, unified network management system and the corresponding communication network equipment interoperable access interface, so that the whole network management system functional hierarchy is more clear, easy implementation of network management business module; the system based on the framework enables unified NMS network element management, network management can be independent of the specific equipment to avoid the R & D work duplication of each managed device interface and improve the development efficiency as well as the maintainability and scalability of the system, which laid the foundation for the provision of integrated access and reference for the design and development of next-generation telecommunications network management.
