Patent ID: 8653956

Claim:
A system configured to provide a notification when an asset crosses a boundary, comprising: a wireless transceiver configured to wirelessly receive a boundary request message requesting the establishment of an initial-location boundary relative to the location of the asset at the time the transceiver receives the boundary request message; a processor coupled to the wireless transceiver configured to compare, subsequent to the time the transceiver received the boundary request message, an updated current location of the asset, received from a tracking application apparatus, with the established initial-location boundary; wherein the wireless transceiver is configured to transmit a crossing notification message from a tracking application when a result of the comparing step indicates that the asset crossed the initial-location boundary; wherein the system further comprises a telematics control unit substantially fixed to the asset and a mobile device running a geofence application, wherein the telematics control unit and the mobile device are configured to communicate control, data, information, and other signals with each other over a short range wireless link when the telematics control unit and the mobile device are within a first range of each other, the first range being the range in which the telematics control unit and the mobile device can communicate signals to each other over the short range wireless link, and wherein the mobile device includes the wireless transceiver and processor and wherein the mobile device runs the tracking application; wherein the mobile device is configured to use location information from a GPS module internal to the mobile device when the mobile device and the telematics control unit are not within the first range of each other; and wherein the mobile device is configured to use location information from signals other than GPS signals to determine that the mobile device has moved after a GPS module internal to the mobile device has entered a sleep mode, and to cause the GPS module internal to the mobile device to exit the sleep mode.
