Abstract

A method for transferring an instant messaging and presence (IMP) session from a source device (101) to a target device (103) includes the steps of registering (130) the target device with an IMP server (105), sending (150, 152) historical IMP session information from the source device to the target device, and subscribing (170) the target device to the IMP server. The target device (103) initiates the transfer of historical IMP session information (thus, we refer to it as a “grab” or “grab transfer”), and the target device (103) may optionally instruct the source device (101) to de-register (160) from the IMP server (105). Related methods for the target device and the source device are disclosed as well as an electronic device operable to be either a source device or a target device.

Claims

1. A method for transferring an instant messaging and presence (IMP) session from a source device to a target device comprising the steps of:

registering the target device with an IMP server;

sending historical IMP session information from the source device to the target device; and

subscribing the target device to the IMP server.

2. A method according to claim 1 wherein the step of sending comprises the steps of:

sending a grab request from the target device to the source device via the IMP server; and

sending historical IMP session information from the source device to the target device via the IMP server.

3. A method according to claim 2 wherein the step of sending a grab request comprises the steps of:

indicating a maximum amount of historical IMP session information requested by the target device.

4. A method according to claim 2 wherein the grab request directs the source device to de-register from the IMP server.

5. A method according to claim 1 further comprising the step of:

continuing the IMP session using the target device.

6. A method according to claim 5 further comprising the step of:

continuing the IMP session using the source device.

7. A method in a target device to grab transfer an instant messaging and presence (IMP) session from a source device comprising the steps of:

obtaining a selected mode for transfer of an IMP session;

sending a registration request to an IMP server;

sending a grab subscribe request to the source device;

receiving IMP session information from the source device; and

subscribing to the IMP server.

8. A method according to claim 7 wherein the step of sending a grab subscribe request to the source device comprises:

sending the grab subscribe request to the IMP server.

9. A method according to claim 7 wherein the step of receiving IMP session information from the source device comprises:

receiving IMP session information from the IMP server.

10. A method according to claim 7 wherein the step of sending a grab subscribe request to the source device comprises:

sending an aggressive grab subscribe request.

11. A method according to claim 7 wherein the step of sending a grab subscribe request to the source device comprises:

sending a passive grab subscribe request.

12. A method in a source device to transfer an instant messaging and presence (IMP) session to a target device comprising the steps of:

participating in an IMP session;

receiving a subscribe request from a target device; and

sending IMP session information to the target device.

13. A method according to claim 12 wherein the subscribe request is a passive subscribe request.

14. A method according to claim 13 further comprising the step of:

continuing the IMP session.

15. A method according to claim 12 wherein the subscribe request is an aggressive subscribe request.

16. A method according to claim 15 further comprising the step of:

de-registering from the IMP session.

17. An electronic device comprising:

a user interface controller operable to control user interface elements;

a grab user interface controller operable to obtain grab mode information from a user;

a processor, coupled to the user interface controller, having;

a grab module operable to provide instructions to enable a grab transfer of an instant messaging and presence (IMP) session from a source device;

a memory having;

a presence portion, for storing presence information;

a log/incoming messages portion, for storing incoming chat information; and

an outgoing messages portion, for storing messages to be sent.

18. An electronic device according to claim 17 wherein the grab module further comprises:

a grabbed module operable to provide instructions to enable a grab transfer of an IMP session from the electronic device to a target device.

19. An electronic device according to claim 17 wherein the grab module further comprises:

a grabber module operable to provide instructions to enable a grab transfer of an IMP session from a source device to the electronic device.

20. An electronic device according to claim 17 wherein the memory further comprises:

a grabbed content portion, for buffering historical IMP session information.

21. An electronic device according to claim 17 further comprising:

a display, coupled to the user interface controller; and

a keyboard, coupled to the user interface controller.
