1. A method for determining a path traversed by a mobile communication device, the method comprising:

  • providing a tower transition data;

    receiving at least two cellular network tower IDs sequentially;

    identifying at least one head GPS coordinate and at least one tail GPS coordinate associated with each transition between two consecutive cellular network tower IDs from the tower transition data;

    estimating a distance between each tail GPS coordinate and each head GPS coordinate between two consecutive transitions; and

    selecting at least one most probable transition associated with a minimum distance between two consecutive transitions; and

    determining the path traversed by the mobile communication device based on the at least one most probable transition.
