Analysis And Design Of Integrated And Unified Service Platform For Mobile-E-Government Based On SOA Architecture

The development of Mobile E-Government stays in early stages in our country, and the existing E-Government systems often encounter "separated government" and "government information island" problems because of the lack of effective management, daily operation of the mechanism in the agreement, and complete considerations of standards and technologies.All of these lead to the less reasonability of system construction,and the high cost of upgrading and transformation.Most of information resources management of government departments are in fragmented states, which bing the poor openness and sharing of these infrmation. Lots of useful information is scattered in various dead corners and get no utilization and sharing efficiently. Meanwhile, the existence of cross terms between different government departments making the demand of joint law enforcement, collaboration and other issues increased.Therefore, there has an important practical significance to promote the development of centralization of resources and internal sharing of government data, and to achieve a large concentration of government sector data, strengthening the integration of information resources, sharing, security and effective utilization in the development of mobile E-Government. For these problems encountered in the development, this paper focuses on the following two issues:1. Because the existing government services have different forms, and various government departments have their own data resources.Besides, every sort of resources and services has different structures.All of these reasons bring a big difficulty to the construction of integrated mobile service platform.2. Request types of mobile terminal and access of data types have a variety of sorts. With the time fly and social needs, the original pattern will be changed and improved. Therefore mobile E-Government platforms need to shield external diversity of the requested service and provide unified access to external.Against to the above issue existed to mobile E-Government,this paper gives an emphasis of analysis and design of the integration of a unified service platform for mobile E-Government.This subject adopts SOA architecture and J2ME platform to design cross-sectoral, multi-service integrated E-Government systems which run on the server side.The designing ideas of this service platform are as following.1. The basis of SOA architecture is services, and services in mobile government are the composition of a series of steps in inner logical link. So we can decompose the services into a series of logical unit, which contains logical process that descripes computer underlying operations.All of the logical unit through the decomposition of a service forms the domain of this service.2.We make use of certain computer algorithms to package the logical units which are distributed in different domains and owns same logical process as a public service component.These public service component are described by WSDL as standard services model.3. After service platform receives the service request from mobile terminal, the service platform will compare the standardized service request with existing standard service model to find the corresponding standard model.And this standard service model will redirect the service request to specific application processing procedures. Thus the service request process will be completed.By the method of decomposition of service delivery and the establishment of standards of service model.We can realize the uniform standardized of various of service request and business data,so as to meet the changing needs of government services,and finally to achieve a unified and integrated mobile E-Government service platform.
