The Design And Research Of Home Location Register Software Subsystem In Mobile Communication System

The mobile communication systems make evolutionary change back to the analog mobilecommunication system and the digital mobile communication system, Now the third generation ismaking explosive growth. It can support various, high-speed data transport and high-qualitymultimedia services.The Home Location Register(HLR),which is the central database of the corenetwork in the mobile communications, stores the information of registered mobilesubscribers.One HLR system can control several mobile switching areas and whole mobilecommunication network.With rapid development of the third generation services,the subscriberinformation will become more and more .At the same time,the real-time request of the mobilecommunication system will become higher and higher.Therefore,it is vital to design and developHLR system with high efficiency and mass data.At present ,the mobile operators of china is making revolutionary from the second generationto the third generation. Fixed-line network operators want to operate the third generation mobilecommunication systems. Therefore amalgamation of fixed-line network, the second generationnetwork and the third generation network is necessary.According to the request of amalgamation and real-time efficiency, the human-machineinterface module , server module and database module are separately described in detail indesign and development.Specifically,this article includes the following main parts:1) the solution of real-time problem with high speed database2) the solution of various HLR database with universal database interface3) design and develop HLR Disaster Recovery Center System4) design and develop HLR human-machine interface module5) design and develop HLR server module ,includeing DBIO module, HSDB module ,DBENGINE module and UDB module.
