Based On Corba Technology, Telecommunications Network Management System Design And Realization

As network functions unceasingly increasing,TMN becomes more and more complex, and the management application based on the traditional TMN standards comes to show some limitations. Meanwhile, CORBA, one mature standards which is used to define distributed system, is one effective way to solve the shortage of the Q3 interface, and it also can resolve the problems when realization the real system.According to hiberachy model of TMN, a management interface for NML must be provided by EML. This dissertation expatiate the principle of the implementation of the interface which provide manufacturer's element management information for superior management network systems.According to the network management interface criterions between NMC and OMC in CDMA95/1X network management established by China Unicom on the basis of CORBA technology,northbound interface must not only implements the configuration management function, performance management function and exception management function, but also need to figure out hot deployment technology problem to reach the situation that can deploy and upgrade northbound interface when system is running. Meanwhile, owing to the asynchronous between foreground and background, many problems appeared when the performance data collecting module is running. And this is a mostly puzzle which embarrass TMN system works perfectly. Moreover, load balancing is dire needed as the operation and visit time of TMN system rised.This dissertation discusses the advantages when CORBA applied in TMN and designs the northbound interface by CORBA technology. The theory of this design and application is introduced by taking the configuration module as an example. Moreover, it proposes one solution to the performance data colletion, and provides one method, base on the selector model, to meet the requirement that unceasingly increasing visit of network management system. This dissertation also proposes one method to resolve the ploblem of the hot deployment.The northbound interface, based on CORBA, can smoothly connects to other professional subnets and help for realization of the real system. The achievement of this dissertation have been applied to ZXCOMC₁X,ZXCOMC₃G and WiMAX network management systems and it proved to be works quite well.
