Claim One:
1. A method comprising: defining, by a mobile location apparatus comprising a processor, a first location zone based, at least in part, on a geographic coverage area of a cell serving a mobile communication device; determining, by the mobile location apparatus, a second location zone associated with the mobile communication device, wherein the second location zone is determined based, at least in part, on a corresponding strength of signal associated with each of a plurality of cells measured by the mobile communication device, wherein the corresponding strength of signal associated with each of the plurality of cells measured by the mobile communication device is used to calculate a corresponding distance between the mobile communication device and a respective base station of each of the plurality of cells, and wherein the corresponding distance between the mobile communication device and the respective base station of each of the plurality of cells is used to determine the second location zone associated with the mobile communication device; receiving, by the mobile location apparatus, from the mobile communication device, first coordinates of the mobile communication device calculated, at a first time period, by a global positioning system of the mobile communication device; determining, by the mobile location apparatus, whether the first coordinates of the mobile communication device are within the first location zone; in response to determining that the first coordinates of the mobile communication device are within the first location zone, determining, by the mobile location apparatus, whether the first coordinates of the mobile communication device are within the second location zone; and in response to determining that the first coordinates of the mobile communication device are within the second location zone, associating, by the mobile location apparatus, the first coordinates of the mobile communication device with a high confidence level as being an estimate of a geographical location of the mobile communication device.
