Abstract

A mobile device adapted to provide an indication of the proximate co-presence of a buddy—another user who has agreed to be indicated as nearby—using a short-range (local) transceiver to scan for a low-level identifier associated with a compatible short-range transceiver in a mobile device operated by the buddy. The mobile device provides an indication of proximate co-presence of another only in case of permission.

Claims

1. A method, comprising:

a first mobile device using a short-range radio transceiver included in the first mobile device to discover an identity expression of a user of a second mobile device, a corresponding low-level identifier permanently assigned to the second mobile device, and a flag indicating if the user of the second mobile device grants permission to be monitored, and storing the low-level identifier, identity expression and flag for later use; and

the first mobile device using the short-range radio transceiver to monitor for proximity co-presence of the second mobile device by polling for the second mobile device using the stored low-level identifier of the second mobile device but only if the stored flag indicates that the user of the second mobile device has granted permission to be monitored.

2. A method as in claim 1, further comprising the first mobile device providing a signal to a user of the first mobile device alerting the user as to the proximate co-presence of the second mobile device, and establishing a voice connection with the second mobile device via a radio signal if the first mobile device receives an input from the user of the first mobile device that such a voice connection is to be established.

3. A method as in claim 1, wherein to discover the identity expression and the corresponding low-level identifier of the second mobile device, the first mobile device broadcasts a scanning signal via the short-range radio transceiver asking for the low-level identifier.

4. A method as in claim 3, wherein either the scanning signal also asks for the low-level identifier, or the first mobile device asks for the identity expression after the second mobile device responds to the scanning signal.

5. A method as in claim 1, further comprising the first mobile device providing to the second mobile device an identity expression of a user of a first mobile device, a corresponding low-level identifier permanently assigned to the first mobile device, and a flag indicating if the user of first mobile device grants permission to be monitored, wherein the first mobile device displays to the user of the first mobile device the identity expression of the user of the second mobile device for use by the user of the first mobile device in deciding whether to grant permission to be monitored.

6. A mobile device, comprising:

one or more modules configured for using a short-range radio transceiver included in the mobile device to discover an identity expression of a user of another mobile device, a corresponding low-level identifier permanently assigned to the other mobile device, and a flag indicating if the user of the other mobile device is willing to be monitored, and storing the low-level identifier, identity expression and flag for later use; and

one or more modules configured for using the short-range radio transceiver to monitor for proximity co-presence of the other mobile device by polling for the other mobile device using the low-level identifier of the other mobile device but only if the stored flag indicates that the user of the other mobile device has granted permission to be monitored.

7. A mobile device as in claim 6, further comprising:

one or more modules configured for voice communication via a radio signal; and

one or more modules configured for establishing a voice connection with a user of another mobile device via the radio signal based on information included with or associated with the identity expression of the user of the other mobile device.

8. A mobile device as in claim 7, wherein the mobile device is configured so that the voice connection is established via a radio access network of a cellular communication system.

9. A mobile device as in claim 6, wherein the mobile device includes one or more modules configured for broadcasting a scanning signal via the short-range radio transceiver asking for the low-level identifier.

10. A mobile device as in claim 9, wherein either the scanning signal also asks for the low-level identifier, or the mobile device also includes means for asking for the identity expression after the other mobile device responds to the scanning signal.

11. A mobile device as in claim 6, wherein the mobile device includes one or more modules configured for checking that the mobile device has received permission from the other mobile device to monitor for proximity co-presence of the other mobile device.

12. A mobile device as in claim 11, wherein the mobile device includes one or more modules configured for displaying to a user of the mobile device the identity expression of the user of the other mobile device.

13. A mobile device as in claim 6, wherein in order to monitor for the proximity co-presence of the other mobile device, the mobile device includes means for polling the other mobile device using the low-level identifier for the other mobile device stored in the mobile device, and means for determining whether permission for polling the other mobile device is also stored in the mobile device.

14. A system, comprising:

a plurality of mobile devices as in claim 8, and further comprising the radio access network and associated core network of the cellular communication system.

15. A mobile device, comprising:

a discovery module configured for using a short-range radio transceiver included in the mobile device to discover an identity expression of a user of another mobile device, a corresponding low-level identifier permanently assigned to the other mobile device, and a flag indicating if the user of the other mobile device grants permission to be monitored, and storing the low-level identifier, identity expression and flag for later use; and

a monitoring module configured for using the short-range radio transceiver to monitor for proximity co-presence of the other mobile device by polling for the other mobile device using the low-level identifier of the other mobile device but only if the stored flag indicates that the user of the other mobile device has granted permission to be monitored.

16. A mobile device as in claim 15, further comprising:

a cellular telephone functionality module configured for voice communication via a radio signal, and for establishing a voice connection with a user of the other mobile device via the radio signal based on information included with or associated with the identity expression of the user of the other mobile device.

17. A mobile device as in claim 16, wherein the mobile device is configured so that the voice connection is established via a radio access network of a cellular communication system.

18. Apparatus comprising:

means for discovering with a first mobile device using a short-range radio transceiver an identity expression of a user of a second mobile device, a corresponding low-level identifier permanently assigned to the second mobile device, and a flag indicating if the user of the second mobile device grants permission to be monitored, and storing the low-level identifier, identity expression and flag for later use; and

means for monitoring with the first mobile device using the short-range radio transceiver a proximity co-presence of the second mobile device by polling for the second mobile device using the stored low-level identifier of the second mobile device but only if the stored flag indicates that the user of the second mobile device has granted permission to be monitored.

19. A method as in claim 18, further comprising the first mobile device providing to the second mobile device an identity expression of a user of a first mobile device, a corresponding low-level identifier permanently assigned to the first mobile device, and a flag indicating if the user of first mobile device grants permission to be monitored, wherein the first mobile device displays to the user of the first mobile device the identity expression of the user of the second mobile device for use by the user of the first mobile device in deciding whether to grant permission to be monitored.
