Jamming presence

1. A method to provide alternative communications during jamming in a presence system, comprising:

registering a mobile device as a presentity to a presence server in the presence system;

detecting a communication jamming of the mobile device;

providing information related to the detected communication jamming as a state information to the presence server; and

upon attempting to communicate with the mobile device while being jammed, selecting an alternative communication suggestion that is dependent on a physical location of the presentity and an inferred estimate of when the presentity will be available in the future, and providing the alternative communication suggestion as state information to the presence server.

2. The method of claim 1 comprising providing a presentity contact preference.

3. The method of claim 1 wherein the alternative communication suggestion is voice mail.

4. The method of claim 1 wherein the alternative communication suggestion is instant messaging.

5. The method of claim 1 wherein the alternative communication suggestion is e-mail.

6. The method of claim 1 comprising determining a security authorization of at least one of:

a caller; and

a device attempting to communicate with the mobile device.

7. The method of claim 1 comprising providing a presentity physical location.

8. The method of claim 1 comprising directing to an alternative contact.

9. The method of claim 1 comprising upon attempting to communicate with the mobile device, providing at least one of:

a caller; and

a device attempting to communicate with the mobile device,

with an alternative contact information.

10. The method of claim 1 comprising combining the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state.

11. The method of claim 1 comprising providing the information related to the detected communication jamming prior to attempting the communication.

12. A non-transitory computer readable medium comprising instructions for:

registering a mobile device as a presentity to a presence server;

detecting a communication jamming of the mobile device; and

selecting an alternative communication suggestion that is dependent on a physical location of the presentity and an inferred estimate of when the presentity will be available in the future, and

providing the alternative communication suggestion as state information to the presence server.

13. The non-transitory computer readable medium of claim 12 comprising instructions for supplying selective communications jamming within a user's home.

14. The non-transitory computer readable medium of claim 13 wherein the selective jamming is timed.

15. The non-transitory computer readable medium of claim 13 wherein the selective jamming excludes a pre-determined set of callers.

16. The non-transitory computer readable medium of claim 12 comprising determining a security authorization of at least one of:

a caller; and

a device attempting to communicate with the mobile device.

17. The non-transitory computer readable medium of claim 12 comprising instructions for combining the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state.

18. A system adapted to provide alternative communications during jamming in a presence system, comprising:

a mobile device registered as a presentity on the presence system; and

a presence server on the presence system, the presence server adapted to:

detect communication jamming of the mobile device;

receive an alternative communication suggestion that is dependent on a physical location of the presentity and an inferred estimate of when the presentity will be available in the future; and

provide the alternative communication suggestion as state information to at least one watcher of the mobile device.

19. The system of claim 18 wherein upon attempting to contact the mobile device while being jammed, at least one of:

a caller; and

a device attempting to communicate with the mobile device,

is provided with the state information and offered an alternative communication suggestion.

20. The system of claim 18 wherein the presence server combines the information related to the detected communication jamming with a presentity schedule to produce a presentity inferred state.
