Design And Implementation Of Web Service Which Applied In The Network Control Center Of Beidou Satellite

Web Service is the focuses of IT field today. For the sake of exhibiting the business application service in Internet or intranet by using standard XML protocol and information format, Web Service provided a calculation of distribute type technique.Web Service can encapsulate information, action, the representation of data and business process in the same way and they do not need to consider what kind of system and device the applied environment will use by using standard XML protocol. Web Service structure a technology tier which independent of terrace and program language on base of existing different terraces, the connection and integration of the applications on the different terraces by the technology tier. By it, companies can pack their e-business as components and then integrate these components dynamically according to the business process.This paper discusses design and implementation of Web Service which applied in the network control center of Beidou satellite, the network control center of Beidou satellite base on the Beidou satellite locating navigational system, which face to the different business demands of users. Web Service is a appearance of the network control center, in the meantime, which is a bridge of business changing from users to the network control center each other to the users which access by web, Web Service can provide the services of purview attestation, menu navigation, query, location display and SMS communication.This paper mainly makes an in-depth research on the design and implementation of Web Service which in the special environment of the satellite locating navigational system.First, it introduces the network control center of Beidou satellite and the Beidou satellite locating navigational system, which are the background of design and implementation of Web Service, and the function and status of Web Service in system. Then , it totally analysis the identity and structure of Web Service, and expound several technologies of Web Service: the first is XMLwhich is the base technology, the second is WSDL which is the interface description language of service ,the third is SOAP which is communication and message transferring of service, the fourth is UDDI which is the description, discovery and integration of service .Base on the theories of Web Service, this paper introduces the design and implementation of Web Service which applied in the network control center of Beidou satellite, and mainly describes the realization terrace and design idea, and the work flow of modules, classes, interfaces and the realization methods of interfaces .Finally, this paper analyses the function and testing of Web Service, and sum up the paper ,the main research work in the next phase is to realize the operation each other, the security and transaction of Web Service.
