A Novel Architecture for Ubiquitous Location Based Services in TD-SCDMA
Advances in mobile devices, sensors and wireless networks have motivated the development of location based services applications. However, most of the positioning methods specifically designed for either indoor or outdoor and their accuracy and precision differs greatly, so its difficult using only one positioning method to meet all peoples demands. This paper proposes a new architecture for ubiquitous location based services (LBS) in TD-SCDMA (Time Division Synchronous Code Division Multiple Access).In this architecture the proper positioning methods are determined by the uses surroundings and the demands of accuracy and precision, and the problem that the uses environments change has been also resolved commendably. And this architecture solves the problem that environment changes while positioning.The simulation shows that everyone can use the location based services anywhere and anytime with the mobile terminal through this architecture.
