The Development Of Distributed Mobile Positioning

The migration value-added service has brought for the mobile interned multi-level, the multi-type's service, gave the mobile communication to bring the infinite opportunity and the new economic growth without doubt, its oneself after became the telecommunication operator's competition focal point, also after becoming our country joined WTO, the foreign capital attention key point. Most can manifest the mobile communication full of vitality place moves the value-added service, but the running fix service will become in the mobile interned application the value-added service key point, its market oneself presents the tendency which one kind of paroxysm grows.Currently, with the advent of 3G system and growth of the Wireless network, Location based positioning service has been paid highly attentions. Besides that, the broader bandwidth enriches the varieties of the Mobile positioning service.The service that the system offered includes that not only to provide the real-time processing map where the user locates, but also to utilize the maps to redirect the user to the restaurant, shops, and other business that the user may interested in. In order to attract users with different interests, we proposed an interesting concept here and this location based service is driven by the community, which is to let the user to build up their own community and share the location information based on the service. The location information within the community could either be shared among the subscribers or be open to the rest of the communities.The paper presents the current development and background of the location based service. After that, the paper brings forward the basic theory and realistic technology of several common mobile position technologies and compares their advantages and disadvantages synthetically and systematically. Then the design and technical details of ERLANG distributed system that we developed is put forward. Finally the distributed application and the prospect of mobile position technologies are expounded...
