The Design And Implementation Of Configuration Management Subsystem In 3G Network Management

With the development of the scale of the 3rd Generation (3G) mobile communication network, the requirement of network management is increasing. To build a mobile communication system with a strong function, dependable performance, great deficiency is more and more important. Configuration management (CM) is the most important module among the Telecommunication Management Network (TMN). Combines the development experience of the author's work in TMN at Huawei, the author designs and implements a CM subsystem of 3G TMN system.Firstly, this paper summarizes the main content of TMN. Secondly, it describes the technological characteristics of CORBA and XML, and shows their application in 3G TMN. On this basis, the paper puts forward the overall structural design of 3G TMN and the function design of CM subsystem, which can be divided into GUI, Server, Mediation and Platform. GUI is the interface of the system;Server subsystem provides the implementation of user's operation;Mediation subsystem implements the function of user's operation on MO;iMAP Platform subsystem is the basic module of the above subsystems.There are two emphases in this article:1. This paper brings forward an iMAP platform. By providing transparent IDL interface, it implements logical function of CM, such as security management, event management and MO management, thus, avoid designing the reduplicate function and also can provide standard API.2. This paper divides the Mediation layer from Server subsystem, and so it can shield the format difference of report to different network element before transferring to BAM, thus, improves the project's development efficiency.
