Abstract
A computer-implemented mobile device locating method is provided. The method includes determining a current cell sector of a mobile device and comparing the current cell sector with a cell sector list of previously determined cell sectors. A current location of the mobile device is determined if the current cell sector is not listed in the cell sector list. The current location is compared with a last determined location. The current cell sector is added to the cell sector list if the current location is substantially the same as the last determined location. The cell sector list is cleared if the current location is not substantially the same as the last determined location.
