As shown in Figure 1, the invention provides a kind of locating platform technical scheme, system mainly comprises as the lower part:
-positioning service system comprises: the location-server front end, and base station location is inferred information database, and base station position information is calculated iteration module, and location information of mobile terminal is calculated module
-self have a portable terminal (for example: self have the mobile phone of GPS etc.) of GPS positioner
-general portable terminal (for example: do not have the mobile phone of GPS positioner, notebook computer, net book etc.)
-gps satellite is used to the portable terminal that has positioner that the locating information of portable terminal self is provided in the native system
-mobile communication or Wi-Fi base station IDs provide unique identification code information for portable terminal in the native system.
The information of described location-server front-end collection is input to base station position information and calculates iteration module and location information of mobile terminal reckoning module, and described base station position information calculates that iteration module and location information of mobile terminal reckoning module and base station location supposition information database link to each other; Described portable terminal and the general portable terminal that self has the GPS positioner do not require while and described base station and location-server front end communication.
As shown in Figure 2, in the native system, the portable terminal self-position information that self has the GPS positioner reports the flow process of positioning service system to be:
(1) portable terminal that has a GPS positioner is obtained the latitude and longitude information of self by the GPS positioner;
(2) portable terminal of the described GPS of having positioner obtains self residing antenna for base station id information and signal strength signal intensity;
(3) latitude and longitude information that just self obtains of the portable terminal of the described GPS of having positioner, antenna for base station recognition code information and the signal strength signal intensity that obtains sends to the location-server front end by mobile Internet http agreement at present;
(4) the location-server front end reports the mobile terminal data of receiving and passes to base station position information reckoning iteration module, is optimized iteration with the positional information to this antenna for base station cognizance code;
(5) if iteration calculate successfully, with the new antenna for base station cognizance code position latitude and longitude information updated stored extrapolated in base station position information tentative data storehouse.Unsuccessful as the iteration reckoning, then the base station position information renewal is invalid.

The portable terminal A that has GPS incites somebody to action own residing latitude and longitude information A and CellID=6789 in the antenna for base station coverage of CellID=6789, signal strength signal intensity=5 and other aforesaid reporting parameters are given the locating platform server;
The base station information CellID=6789 that other portable terminals (for example B) that have GPS also obtain it, signal strength signal intensity=4 and the latitude and longitude information of self obtaining by GPS report the locating platform server;
Base station position information is calculated that iteration module reports each data and is all once calculated iteration extrapolating the latitude and longitude information of base station more accurately, and upgrades base station location and infer information database;
The portable terminal (for example C) that self does not have positioning equipment sends to the locating platform server with its residing base station information CellID=6789 and signal strength signal intensity=3 and makes position enquiring;
Locating platform is inferred the corresponding supposition latitude and longitude information of inquiry this antenna for base station ID (Cell ID) the information database according to the base station information that portable terminal C provides from base station location, calculates that by terminal positional information module is optimized reckoning to the latitude and longitude information of portable terminal C then;
The locating platform server returns to portable terminal C to longitude and latitude and the credible radius information of the portable terminal C that reckoning obtains for 800 meters.
