Design For CORBA Based Mobile Switch Network Integrated Network Management System

With the rapid development of telecommunication in China, the scale of the mobile switch network becomes larger and larger , meanwhile the network structure becomes more and more complex, and the number of customers increases continuously, therefore, the operation&maintain load everyday gets increased constantly. So in order to improve the operation level and the competitive power , all of the telecommunication companies make a higher request for the function and the efficiency of the net work management. Then the INMS gets emerged and developed quickly as to meet the require for the management ways.The function of the INMS is complicated and what it controls is the various equipments of all kinds of companies on the communication network. So these factors make it include a variety of modules of different kinds of application and adaptive functions. So the INMS itself is just a distributed system.CORBA is the criterion of the distributed system that the OMG takes the responsibility to establish and issue. It guaranties the intra/mutual-maneuverability of the application programs and the independence of the hardware platform, operating system, programming language, network and the communication protocal. It has three key components: IDL(Interface Definition Language), ORB(Object Request Broker), standard communication protocol -HOP.As the research purpose of this paper, it does architecture design, module design and interface design between modules, and based on the designs it introduces a implement scheme for INMS. The scheme is based on CORBA, according to the distributed feature and the function requirement of the INMS. The main features of the scheme include clear levels, open interfaces, public service interfaces, better extensibility and maintainability. Thus it is fairly helpful to hierarchical division and extensibility design.The paper includes the introduction of the CORBA technology, mobile switch network, each module level, and the design of hierarchical division and interfaces. Meanwhile it contains the explanation of the main function case under the structure. And at the same time it introduces the progress of system development to verify the maneuverability.
