The Design And Implementation Of Wireless Data Service Authentication And Accounting System

With the rapid development of communications technology, mobile services infiltrate every aspect of people's lives, greatly facilitate people's lives.CDMA is the one of the fastest growing wireless mobile communications technology, which provides various types of business in the signal quality, safety, power and reliability, have shown a strong technological advantage. In order to achieve full service communications and prosperity, meet different customer's demand, telecom operators and service providers will face great challenges of new business models. Accompanied by the world's third-generation mobile communication system operation, the advent of a new mobile communications era is booming. Therefore, in order to gain rapidly growing in the field of "Tianyi" mobile communications, China Telecom Wireless Data authentication and accounting system business functions need to be more accurate and higher requirements.This paper follows the RADIUS authentication protocol,J2EE and CORBA system standard specifications, according to the distributed, scalability and security requirements for the designed system. In this project, author took part in designing this system which based on business requirement analysis. It contains analysis and design of functional structure, physical structure and logical structure. This system mainly consists of business management, system management, configuration management, analysis of OCS and other agreement, c+w unified authentication, IT data service system interface and other subsystems. At the beginning, this paper introduces the major theories and techniques, which relate to wireless data service authentication and accounting system, and the design of the structure and functions of the system. Subsequently,author represent the design and implement of the AAA business management authorization subsyste, AAA configuration and roaming management subsystem, VPDN and business binding subsystem, which improve the flexibility,security and efficiency of authentication and authorization business system.At present, the system can carry out a variety of wireless data services, authentication and accounting, at same time it accredit flexibility and accurately users who access to PDSN from different manufacturers. The system also realizes the VPDN authentication and accounting bind to the user service, reach the dividing between users and business,as to providing the possibility of realizing provide different services for different customer in the future. Furthermore, it provides a good compatible interface, which can realize the communication with WAP gateway, prepaid system, CRM system, integrated network management system and other business systems, meets the business requirement for the operation support system.the system has been running for one year, stable performance basically reached the expected goals, and also made good effects.
