摘要
基于位置的移动服务需要设计高效、稳定和可扩展的体系结构与开发方式,提出了一种基于Web服务的LBS体系结构(WS-LBS),并设计了WS-LBS系统框架,实现了空间信息服务的构建与发布机制,扩展了终端用户,实现了一个WS-LBS原型系统。
To meet the demands of efficient, stable and scalable architecture and implementation techniques of location-based mobile services, this paper proposes an architecture for LBS based on Web service technologies, i. e. , Web Service based LBS （WS-LBS）. WS-LBS has multi-layers, and consists of database server, global spatial information servers, local spatial information servers and mobile clients. Web service technologies are adopted in WS-LBS. UDDI is used to publish global spatial information services, and URL address is used for lorcal spatial information services publishing. At the mobile client site, SOAP client technology is adopted for end-users to access to remote spatial information services. Two kinds of WS-LBS clients are implemented, i. e. J2ME client and WinCE client. A WS-LBS prototype is implemented by Java and C^# languages, providing transparent access to distributed spatial information services for various mobile end-users.
