The Research And Implementation Of SOA In The Platform Of Mobile Value-Added Service

As the fast development of mobile communication technology and the rising popularity rate of mobile phone over years, the mobile value-added service successfully meet the demand that people want to get information from computer network and very have fast development in past years. The speedy development of society drives it to be the crux of survival and development. The sharp adaption to mission changes, the reduction of business costs and the easily usage and combination of services according to the requirements from business are the essential and significant problems to be survivor and achieve progress in competitions for those value-added service provider or SP.SOA-Service Oriented Architecture is a next generation philosophy of enterprise system construction. SOA packages all of the function applications in an enterprise to services by coarse-grained and low-coupling methods, and classify them into business procedures based to enterprise's demands. These procedures are used by all internal or external co-operational partners. The information exchanges which take place between these services follow universal and standard message forms.The SOA concept and several relative technologies are discussed in this paper firstly. The differences between the SOA based and traditional programming concepts are analyzed carefully. We have made a uniform design of the system interface platform of mobile value-added services by SOA and layered architecture spirits. Secondly we divide the system platform into Data Layer, Access Layer, Brace Layer, Service layer, Orchestration layer and application layer according to the relationships of telecom operators, CPs and SPs and the functional requirements of mobile value-added services platform. At last, we provide the core code of main function modules in each layer.There are many advantages in value-added service platform based on the SOA, such as loosely-coupled coupling, reusable, extendible. On one side, we could reconstruct the business flexibly to make rapid response to the business changes of SP enterprises. On the other side, we may develop a new system very fast.
