Synchronous Data Network Management System Based On J2EE Framework And Its Implementation

The design object of WCDMA(Wideband Code Division Multiple Access), which is as 3G mobile communications, is that WCDMA not only can provide bigger system capability and better communication quality than 2G mobile communications but also can offer seamless roaming and provide kinds of operations including Sound, Data and Mobile Multimedia all over the world. Comparing with 2G mobile communications, the WCDMA system applies lots of key technology, such as RAKE take-over, multi-user examine and measure, aptitude antenna, wireless resource manage technology and power control technology. The purpose of this study is to investigate synchronization method between foreground database and background database in operating maintenance center of WCDMA system. Also the synchronization module between foreground database and background database is implemented. As following is the main content of this study: Introduction of correlative academic knowledge. The correlative technology of J2EE is investigated in advance in this study since WCDMA system is based on J2EE. The performances of real time database, such as system structure, data and business, are investigated since the phenomenon between foreground real time database and background database is quite different. Design of foreground real time database. According to the theory of real time database, the investigation of designing the real time database is going more deeply. Firstly, position of database subsystem in whole system is introduced. Secondly, table structure, index structure and queue structure are introduced in turn. Finally, access interface are investigated. Analysis of synchronization method between foreground database and...
