The Analysis And Design Of Disaster Recovery System Of Beijing Unicom's Integrated Billing And Accounting System

In the past ten years, Internet has experienced a rapid development. The applications become more and more popular. Telecom providers are not only challenged in the opereation mode, but their traditional services are also substituted. Transformation is meant to increase profits. Telecom providers have developed a lot of new services, and service qualifications are continuely improved. All these demands are put forward before the support systems. The three demands of the business supporting continuity, high reliability, continuous operation, disaster recovery, have become the consus of the industry. High reliability and high availability of the business supporting system have become the focus of the telecom provider.The application of business IT system is in direct connection with all important phases, i.e., management, service, cost, efficiency etc. and furthermore, ultimately affect the competitiveness of telecom operators. This essay introduces the concepts and technical realization regarding the disaster recovery of telecom business support system. In case of disaster, the system data and application can be protected through disaster recovery technology, the data can not be lost and the system can be resumed to rerun as soon as possible.IBS(Integrated Billing and Accounting System) is the most important system of Beijing Unicom. System crack or data loss will cost Bejing Unicom the degraded service quality and the lost of enterprise profits. The research on disaster recovery of the billing and accounting system is focused on the introduction of DR systems built in the world, the techniques of Data Copy and Business switch, the essential of DR system constructions. Based on the development mode of BCP (Business Continuous Process), we discussed the analysis of the disaster type, the analysis of the business impact, and the analysis of the enterprise environment, especially used in the IBS. The DR policy is produced on the base of analysis. Scheme designation will produce BCP(Business Continuity Process), including system analysis, configuration scheme, engineering project, and so on. Through all these research, we could conclude the methods on how to establish DR system.The author summarized the experiences and methods of DR construction in the thesis.
