Research And Development Of Mobile Position System Based On GpsOne Technique

With the development of society, people's territory becomes larger and larger, the fundamental information that people need in their activities is time, location, and content. The information related to 'location' is what we needed the most; especially when urgent things happened, we required 'the precise location information'. So, the development and enlargement of location services become the most potential Value Added Service.Mobile users need not only own location and surround information, but also other mobile users' location information. GpsOne based on CDMA in China Unicom is not only high-precise, high-sensitive, but also include indoors, gpsOne solution increased the availability of location business, enlarged covering area, accelerated location speed, gpsOne can provide better location information service to mobile users.This dissertation deeply researched the key technique of realizing mobile location services based on gpsOne technique, the concrete research contents are:On the base of researching WAP and J2ME application architecture, the paper have brought forward mobile location service system architecture separately on WAP and Java cell phone based on gpsOne technologies. The system developed on J2EE, implementing easily retractility and extensibility, and map data is saved in Oracle9i Spatial which is an ORDBMS, which made for the the integration management for space and character data.This paper researched the integration strategy of J2ME and J2EE, and gave and realized a feasible data collection and transmission method. The self-defined geography data format not only kept the tier and objects relation, and decreased the data size of map data wireless transmission, and improved the availability of wireless bandwidth.Today, the application system based on gpsOne network location of wap has not still on China Unicom wireless desktop, so the paper completed network location query; change of map zoom, and around information query on wap desktop, etc. Meanwhile, the paper also completed vector data retrieval, transmission, and the show of map.WAP system has passed cell phone test in Henan Unicom, and WAP network side location realization is pioneer on China Unicom wireless desktop.
