Patent ID: 6901264

Claim:
A method for location determination of mobile cell phones utilizing a plurality of base stations comprising the steps of: a. transmitting a positioning request signal from a base station to a specified mobile cell phone; b. receiving at each of said plurality of base stations a positioning response signal from said specified mobile cell phone to said base stations; c. calculating at each of said plurality of base stations, a time delay value representing the time interval between transmission of a parcel of data from said mobile cell phone to said base stations, using a location device within each of said plurality of base stations, d. transmitting said time delay values to a location database server; and e. estimating the position of the mobile cell phone from data received at said location database server from each of said plurality of base stations; wherein the step of estimating the position of the mobile cell phone from data received at said location database server from each of said plurality of base stations employs a redundancy algorithm chosen to be consistent with the number of said plurality of base stations used for determining the mobile cell phone position, and comprises the steps of: i. compiling location information from each location device within each base station; ii. using said location information as input data to a calculation based on a wireless 3D hyperbolic model; iii. using said redundancy algorithm to calculate the estimated position of the mobile cell phone. whereby a determination of the location of the mobile cell phone is generated.
