The Research And Realization Of AAA Subsystem In The Add-Valued Service Platform

With the development of the telecommunications industry,telecommunication operator faces the traditional voice business weekness which has become stable and even saturation.A wide range of value-added services will become prosperous in the future,but several problems existing in this field hindered the rapid development of value-added services,such as lack of uniform management of service operators, service providers and users as well as lack of uniform management of billing method s and value-added services.In order to solve all these problems and realize the uniform management of value-added service,The research of a new field—Value-Added Service Platform which integrates communication technology,network technology and computer technology is started.The Value-Added Service Platform realizes unified management to value-added services.My paper focus on AAA(Authentication Authorization Accounting)subsystem which completes unified authentication, authorization and accounting functions.AAA subsystem is the core subsystem of this system.In this paper,firstly I introduce the concept about value-added services and value-added management platform,then describe the basic theory,layer model concept of traditional AAA protocol,and introduce the current typical model of AAA.SMP AAA(Sevice Management Protocol AAA) with higher efficiency,more lightweight and expansible advantages is the derivation of traditional AAA.lastly My paper presents the research on SMP AAA protocol,about Specific encoding format,the protocol expansibility,the workflow of protocol,the routing mechanisms of protocol,and the layer of protocol model.Focus of this paper is on the design and implement of AAA subsystem and SMP AAA protocol will be applied to value-added Service platform of the AAA subsystem design.The article firstly simply introduces system's architecture, modular division,technical design and hardware environment of value-added services management system.Then briefly describes AAA subsystem.A detailed description of Authentication Authorization Accounting analysis of data model and the class diagram design of AAA comes later on.Finally I give Web page to introduce AAA subsystem.At the end of this paper,I summarize the development of related technologies and the prospect of this research area.The work of this paper has changed the shotcomings of the value-added services before,through the application of SMP AAA framework,to achieve the unification of Authentication Authorization Accounting for telecommunication operators.With the help of this system,service operators could realize cost-effective management to value-added service and the development of Value-Added Services Platform can be accelerated.This paper has a high reference value for the similar systems that are being developed.
