WLS(Wireless Location Services) will eventually influence the spatial information management market, and it will be one of the most important increment services in the next generation of mobile networks. GIS and spatial database will play a key role in this field. This paper introduces the implementation of wireless location services and its GIS server based on XML technology, including the system architecture, application scheme and the organization of the WLS spatial database. We provide an almost complete procedure of wireless location ser-vices based on our application scheme, which is described with example XML code stream via extended HTTP protocol, also called SOAP. According to practical urban LBS application and wireless communication cell's overall arrangement, we compared two spatial database storage models and draw a conclusion that the flavor of LBS data must be organized by spatial database and independent city style, not by communication cell style. An instance of such a GIS server about wireless location services on UNIX platform is provided at the end of this paper. This type of GIS server can be deployed at the background of GSM, GPRS, WCDMA, CDMA, etc. And it has been completely tested and will be launched into deployment soon. |
