Abstract

One feature includes a mobile device being used as a mobile beacon and proxy for a tracking device that may track an object, such as a pet. The mobile device may act as a beacon that transmits messages over a short range communications link to the tracking device. If the tracking device fails to receive the messages transmitted by the mobile device, it may be assumed that the pet has gone missing, and in response the tracking device may contact a tracking server with its location information via a wireless wide area network (WWAN). Additionally, the mobile device may act as a proxy of the tracking device by transmitting and receiving data to/from the tracking server using its own communication interface on behalf of the tracking device. This helps conserve the battery power of the tracking device because the tracking device does not use its own WWAN interface.

(b) data pertaining to an amount of time the tracking device lost communication with the home beacon; and

/or (c) location information of the tracking device at a time where the tracking device lost communication with the home beacon.

6. The method of claim 3, wherein the tracking device data includes walk-out notifications that indicate that the tracking device has lost communication with the home beacon.

7. The method of claim 6, wherein the tracking device data further includes walk-in notifications that indicate that the tracking device has re-established communication with the home beacon.

8. The method of claim 1, wherein serving as the proxy to the tracking device by communicating with the tracking server on behalf of the tracking device comprises:

communicating with the tracking server via a wireless wide area network (WWAN).

9. The method of claim 1, wherein serving as the proxy to the tracking device by communicating with the tracking server on behalf of the tracking device comprises:

communicating with the tracking server via a wireless local area network (WLAN).

10. The method of claim 1, further comprising:

receiving a beacon request message from the tracking device.

11. The method of claim 10, further comprising:

transmitting a beacon availability message to the tracking device; and

receiving a beacon confirmation message from the tracking device.

12. The method of claim 11, wherein the beacon availability message comprises at least one of energy efficiency information and/or signal to noise ratio (SNR) information of the wireless communication device.

13. The method of claim 1, further comprising:

receiving a unicast beacon request page from the tracking device; and

establishing a short range communications link with the tracking device.

14. The method of claim 1, wherein the beacon signal transmitted to the tracking device supplements another beacon signal associated with another beacon.

15. The method of claim 1, further comprising:

receiving tracking device data associated with the tracking device from a relay device via a peer to peer (P2P) connection.

16. The method of claim 1, further comprising:

receiving a request from the tracking device to obtain the tracking server data via the short range communications link;

transmitting the request to the tracking server for the tracking server data via a first communications interface;

receiving the tracking server data from the tracking server via the first communications interface; and

transmitting the tracking server data to the tracking device via the short range communications link.
