<p>The invention provides a method and system for determining path traversed by a mobile communication device in an unobtrusive manner. The method involves providing a tower transition data involving identifying a set of GPS coordinates associated with a cellular network tower ID, and identifying the tail GPS coordinate and head GPS coordinate of consecutive cellular network tower IDs. Then the distance between the tail and head is estimated, based on which the sequence of cellular network tower IDs are determined, which provides the path traversed by the mobile communication device.</p> |
