Design And Implementation Of Telecom Billing Data Auditing Systems

With the fast maturity and increasing market competition of telecom industry, its market environment in China has been turning out to be reasonable. The telecom operators have been aware that the accuracy of data in the Telecommunication Business Support System plays a more and more important role in improving their service quality and ensuring their business income. Billing data audit, which is an end-to-end audit to operators'income flow, is an economic and effective method to improve the service quality and ensure their income. Nowadays, operators are still adopting the original method in their real work: to find out the holes and offset the loss through manually comparing the data of each link in the formation process of income. However, this method requires more time and energy, possesses lower accuracy, and lacks systematization and versatility. Under this circumstance, it terribly requires an automatic audit platform to accomplish the audit to large amount production data in stead of manual work.The thesis introduces the design process of telecommunication billing data audit system, applying the theories of heterogeneous data integration and balance relation validation in its implementation process, adopting JAVA and XML technologies, and putting forward a more platform-independent and functional-reasonable multi tiers architecture, which will accomplish the data audit in all business process more better even in the complicated data source environments of telecom operators.The main work of the thesis includes:1. Analyze the situation and existing problems of billing data audit; take the heterogeneous data form different support systems as data source of data audit system, and change them into a unified formation for integration and analysis.2. Take balance relation as its core theory for system design; Audit and check the collection link, billing link, account link, write-off link, and report form link through"Five Steps Audit Method"; find out and define the data balance relation among the data in the existing supporting systems, take it as audit regulations of data audit, and audit the data in the production process comprehensively and deeply. 3. Practice the thoughts and methods of software engineering during the process of system development; adopt some mature software engineering technologies and J2EE multi tiers architecture to accomplish the general design of billing data audit system.The development of billing data audit system adopts software engineering methods, followed by the steps of requirement analysis, design, programming, and test. The application has friendly graphical interfaces, a better realization of design objectives, and has been affirmed by all the experts of Chongqing Telecom.
