| This article mainly expounds the two CDMA (code division multiple access) is theimportant content of the exchange of system structure and database system security designand management。Database reliability directly affects the stability of the CDMA switchingsystem stability。Using SQL Server7.0as database management system to carry on theunderlying data storage management, but if you want to design a good database must be tohave a deep understanding of database design process, database design was technology inthe development of the database and application system, refers to for a given applicationenvironment, to construct the optimal database schema, to establish database andapplication system, to store data effectively and meet the application requirements ofvarious users。Database is a new technology of data management, is an important branch ofcomputer science, large information systems are based on database design of the SQLServer database is an extensible high-performance designed for distributed client/Servercomputing, database management system, has realized with the combination ofWindowsNT, provides the enterprise information management system scheme based ontransaction it has high performance design system of advanced management and strongcharacteristics of transaction processing function。CDMA cellular mobile switching system by MSC/VLR (mobile switching center/visitlocation register) HLR/AC (home location register/authentication center) and OMS(operation and maintenance system), and other subsystems, the system to satisfy Chinesedata800MHZ CDMA cellular mobile communication system related technicalspecifications and requirements, and can adapt to the future of mobile communicationnetwork and the requirement of business development of mobile communicationsequipment。OMS subsystem is the interchange of CDMA cellular mobile systems MSS localoperation and maintenance of the system it is CDMA mobile switching system of networkmanagement and centralized monitoring center mainly provides management andmaintenance functions of MSC/VLR。 OMS software system adopts the COM specification and use ADO (ActiveX dataobject) technology to access the database, ADO programming using vc++to realize allthis framework in SQL Server database, SQL Server in the OMS everywhere。OMS software based on TMN and the advanced theory, object-oriented softwareComponent (Component) method is adopted to improve the design and development, thuscan satisfy the telecommunication network management software reliability stabilityspecification and the requirements of high performance, etc, and also has the very goodimportance and extensibility, easy to cut according to user requirements and customization,in the future to introduce all kinds of new network technology services and functions。... |
