Abstract

A method of determining proximity of Bluetooth/Bluetooth Low Energy (BT/BLE) devices, in a connectionless session includes executing a contiguity profile at a first device, the contiguity profile providing for connectionless proximity determination. The method further includes determining a proximity of a second device using Bluetooth/Bluetooth Low Energy (BT/BLE) protocol without establishing a Bluetooth/Bluetooth Low Energy (BT/BLE) connection to the second device.

Claims

1. A method of determining proximity of Bluetooth/Bluetooth Low Energy (BT/BLE) devices, in a connectionless session, the method comprising:

executing a contiguity profile at a first device, the contiguity profile providing for connectionless proximity determination; and

determining a proximity of a second device using Bluetooth/Bluetooth Low Energy (BT/BLE) protocol without establishing a Bluetooth/Bluetooth Low Energy (BT/BLE) connection to the second device.

2. The method of claim 1, wherein the contiguity profile provides multidirectional proximity.

3. The method of claim 1, wherein the contiguity profile specifies that the first device is a proximity Reporter and a proximity Monitor concurrently.

4. The method of claim 3, wherein the contiguity profile specifies that as a proximity Reporter the first device advertises with advertisement messages and that as a proximity Monitor the first device scans for advertisement messages and determines proximity based on advertisement messages.

5. The method of claim 4, wherein the first device functions as the proximity Monitor and receives an advertisement message from the second device and based on the advertisement message performs the determining.

6. The method of claim 1, further comprising:

triggering a first proximity event when the proximity is less than a first proximity threshold.

7. The method of claim 6, further comprising:

triggering a second proximity event when the proximity is greater than a second proximity threshold.

8. The method of claim 7, wherein the first proximity event is the activation of a system in the second device and the second proximity event is the deactivation of the system in the second device.

9. The method of claim 1, further comprising:

triggering a first proximity event when the proximity is less than a first proximity threshold;

triggering a second proximity event when the proximity is less than a second proximity threshold; and

triggering a third proximity event when the proximity is less than a third proximity threshold;

wherein the second proximity threshold is closer to the second device than first proximity threshold and the third proximity threshold is closer to the second device than the second proximity threshold, and the first, second, and third proximity event relate to a wake up and activation of the second device.

10. The method of claim 6, further comprising:

triggering a first proximity event when the proximity is less than a first proximity threshold, wherein the proximity event is the establishment of a connection, wherein the connection is of a first type, the first type selected from the group consisting of WiGig, WiDi, and Bluetooth CCF (Closed Communication Function).

11. The method of claim 1, wherein the first and second device are not paired.

12. A system for determining proximity of Bluetooth/Bluetooth Low Energy (BT/BLE) devices, in a connectionless session, the system comprising:

a first mobile device, the first mobile device configured to

execute a contiguity profile, the contiguity profile providing for connectionless proximity determination; and

determine a first proximity of a second device using Bluetooth/Bluetooth Low Energy (BT/BLE) protocol without establishing a Bluetooth/Bluetooth Low Energy (BT/BLE) connection to the second device.

13. The system of claim 12, wherein the contiguity profile provides multidirectional proximity.

14. The system of claim 12, wherein the contiguity profile specifies that the first device is a proximity Reporter and a proximity Monitor concurrently.

15. The system of claim 14, wherein the contiguity profile specifies that as a proximity Reporter the first device advertises with advertisement messages and that as a proximity Monitor the first device scans for advertisement messages and determines first proximity based on advertisement messages.

16. The system of claim 15, wherein the first device functions as the proximity Monitor and receives a first advertisement message from the second device and based on the advertisement message determines the first proximity.

17. The system of claim 12, wherein the first and second device are not paired.

18. A computer-readable non-transitory storage medium that contains instructions, which when executed by one or more processors result in performing operations comprising:

executing a contiguity profile at a first device, the contiguity profile providing for connectionless proximity determination; and

determining a proximity of a second device using Bluetooth/Bluetooth Low Energy (BT/BLE) protocol without establishing a Bluetooth/Bluetooth Low Energy (BT/BLE) connection to the second device.

19. The medium of claim 18, wherein the operations further include instructions for the contiguity profile providing multidirectional proximity.

20. The medium of claim 18, wherein the operations further include instructions for the contiguity profile specifies that the first device is a proximity Reporter and a proximity Monitor concurrently.

21. The medium of claim 20, wherein the operations further include instructions for the contiguity profile specifies that as a proximity Reporter the first device advertises with advertisement messages and that as a proximity Monitor the first device scans for advertisement messages and determines proximity based on advertisement messages.

22. The medium of claim 21, wherein the operations further include instructions for the first device functions as the proximity Monitor and receives an advertisement message from the second device and based on the advertisement message performs the determining.
