| With 3G licences issued, the entire communications industry will be re-structure, and technological progress will produce enormous market space. For the traditional fixed-line operators, having 3G mobile licence means having the right to operate mobile business, and this will break the single fixed-line operating mode. At present, the fixed-line operator is in the process of 3G communications I nfrastructure construction, in order to operate the mobile business immediately after the licence issuing. For fixed-line operators, the biggest feature of 3G is mobility, and in order to meet the customers' requirements of mobility, supporting systems need to accept bussiness cross province ; And this is a major challenge to the traditional fixed-line operators.The direct challenge of remote business processing is to bring the provincial telecom support systems application integration. As the heterogeneous characteristics, the systems are very difficult to access each other. Web Service-based Enterprise Application Integration programme can resolve this problem; it uses Web Services Technology to package to achievement details of the application. It uses a series of standardard protocols to develop Web services which is platform independent and programming language independent, and thus it can reduce the coupling of the application system and make full use of existing resources.On the demand for remote business processing, this paper deptly studies the issue of interoperability, integration and collaboration conduct between enterprise application systems, and introduces related technology and architecture which is based on Web Service, including XML, SOAP, UDDI, WSDL, and so on; And then, the paper proposes the Enterprise Application Integration framework based on Web Service; and discusses the core question of the framework. Ultimately with the status quo of existing telecom supporting systems, it designs and realizes the remote business processing system. |
