Research On Application Of Resources Conformity Technology Based On SOA In Enterprise Information Platform

Management support systems play an increasingly prominent role in enterprise management and operations of China Mobile along with the implementation of excellent engineering, the advancing of the slogan of "creating One CM (One China Mobile)", making strategic objectives to improve core competence and overseas market exploration. As the owner of worldwide largest telecommunication market value, China Mobile obtain performance report data from the integrated statistics of ERP system. Office automation system deals with tens of thousands of documents every day to ensure that everyone could get company operation policies. Not only standardized terminals enhance the management of them inside the company, but also legal softwares improve the image in the international capital market of China Mobile. Now advanced normative high-efficiency management support system has become the important part of world first-class enterprise strategies in China Mobile.Prototype system of this thesis is based on existing enterprise information systems in mobile telecommunications industry. The contents discussed firstly include the survey of management information systems in China Mobile, development survey of enterprise informatization in IT fields, main applications and issues worthy of concern in enterprise informatization process. Then a model of MSS(management support system) framework in mobile telecommunication enterprises is proposed. This model consist of simple model of MSS application value, understanding MSS model from eTOM(enhanced Telecom Operations Map) model, MSS business model and MSS technology architecture. MSS technology architecture focused on the hierarchical model of SOA(Service-Oriented Architecture), several key layers of MSS SOA hierarchical model and summarizing MSS perspective model of mobile telecommunication enterprises from SOA hierarchical model.According to the MSS business and technology framework model and practical requirements and long-term development of MSS in China Mobile, we research the China Mobile MSS development planning and analyze related projects to be constructed in the near future. A MSS conformity scheme of China Mobile is proposed according to service-oriented MSS framework model. ESB(Enterprise Service Bus) is expressed as a key component of SOA basic architecture. ESB provides integrated communications, message passing and incident infrastructure to support service routing and alternate service interaction. It combines the main enterprise integrated modes in use into a entity. ESB gives SOA an infrastructure to accord with enterprise requirements and further to provides appropriate service level, manageability and operations in heterogeneous environment. ESB is discussed from three aspects, target architecture of ESB, services repository and interface implementation reference approaches. As an individual application branch of enterprise information systems, Web SSO(Single Sign-On ) gains more and more attention in construction of enterprise information systems and is further improved and developed along with the development of Web application architecture. By analyzing common Web SSO techniques such as Cookie-based and token-based technique etc. and structures such as agent-based structure, broker-based structure and SAML(Security Assertion Markup Language) protocol etc., we found that implementation of SSO develops gradually from the realization of a single technique to the development of various techniques, and then corresponding structure for SSO implementation is produced. However, only structures can not satisfy various SSO requirements, and then new standard protocol for SSO implementation appears. Current standards are not perfect yet, it is not difficult to see that to resolve all SSO implementation issues among all systems requires very complex development and realization process. According to the above facts SSO solution based on CAS(Central Authentication Service) framework is proposed. Finally the LDAP(Lightweight Directory Access Protocol) based unified user management solution is presented.According to management support systems conformity scheme of mobile, we suggest the process of conformity implementation. Finally, we conclude the study on enterprise information platform resources conformity from aspects of conformity feasibility, conformity necessity and comprehensive benefits.
