LBS服务中的位置感知计算体系研究

Research on Architecture of Location-Aware Computing in Location-Based Service

随着移动通信技术和地理信息技术的发展,基于位置信息的服务(Location_BasedService,LBS)成为新的应用热点。Location_AwareComputing(LAC),即位置感知计算是开展位置信息服务的基础。介绍了LAC的基本概念及国内外研究发展动态,提出了一个完整的位置感知计算体系,有助于很好地设计LAC软件体系结构的逻辑模型,简要讨论了一个LAC计算体系在城市移动空间信息服务的应用模式。

With the development of mobile communication technology and geographical information technology, Location_Based Service(LBS)has been becoming a rising application domain. Location_Aware Computing(LAC)is the foundation of establishing LBS application. The paper introduces the LAC's basic concept and its developing phase in domestic and foreign field. It puts forward an integrated Location_Aware Computing architecture to facilitate the better design of software architecture and logic model. The paper also gives a brief discussion on LAC's application mode in urban mobile spatial information service.
