Abstract

Method and apparatus for performing switchover of a session between different user terminals. The method and apparatus includes means for receiving, from a first device, data representing a session, where the session data includes any application and authentication data required to reestablish the session. The method and apparatus facilitates suspending the session at the first device, and reestablishing the suspended session on a second device using the suspended session data.

Claims

1. A method of performing switchover of a session between different user terminals, comprising:

receiving, from a first device, data representing a session, said session data comprising any application and authentication data required to reestablish the session;

suspending said session at said first device; and

reestablishing said suspended session on a second device using said suspended session data.

2. The method of claim 1, further comprising:

initiating said session from said first device coupled to a first access network; and

reestablishing said suspended session from said second device coupled to a second access network.

3. The method of claim 1, further comprising:

verifying, from said first device, user identity from a centralized security server.

4. The method of claim 1, further comprising:

storing said data representing said session received from said first device at a mobile end-user agent device (MEAD).

5. The method of claim 4, further comprising:

encoding said received data prior to storage.

6. The method of claim 4, further comprising:

initiating said session between said MEAD and first device by sending a security token to said first device.

7. The method of claim 1, further comprising:

conducting said session by initiating application programs local to said first device.

The method of claim 1, further comprising;

conducting said session by initiating service connectivity from a network service provider.

8. The method of claim 1, further comprising:

conducting said session by initiating service connectivity from a network service provider.

9. The method of claim 1, wherein said suspending said session comprises:

sending a termination signal to said first device from a mobile end-user agent device (MEAD) to said first device.

10. The method of claim 9, wherein said suspending said session comprises:

setting said session in a standby mode of operation.

11. The method of claim 1, wherein said suspending said session comprises:

erasing end-user identity information at said first device.

12. The method of claim 1, wherein said suspending said session comprises:

naming said session;

timestamping said session; and

encoding said session information with a secure key.

13. The method of claim 12, further comprising:

storing said secure key at a centralized security server.

14. The method of claim 1, wherein said reestablishing said suspended session on a second device comprises:

requesting user identity verification from a centralized security server; and

unlocking said suspended session using verification from said centralized security server.

15. Apparatus for performing switchover of a session between different user terminals, comprising:

means for receiving, from a first device, data representing a session, said session data comprising any application and authentication data required to reestablish the session;

means for suspending said session at said first device; and

means for reestablishing said suspended session on a second device using said suspended session data.

16. The apparatus of claim 15, further comprising:

means for initiating said session from said first device coupled to a first access network; and

means for reestablishing said suspended session from said second device coupled to a second access network.

17. The apparatus of claim 15, further comprising:

means for storing said data representing said session received from said first device at a mobile end-user agent device (MEAD).

18. The apparatus of claim 15, wherein said suspending said session comprises:

means for sending a termination signal to said first device from a mobile end-user agent device (MEAD) to said first device.

19. The apparatus of claim 15, wherein said suspending said session comprises:

means for erasing end-user identity information at said first device.

20. A mobile end-user agent device for performing switchover of a session between different user terminals, comprising:

at least one port adapted for receiving from a first device, data representing a session, said session data comprising any application and authentication data required to reestablish the session;

a storage device adapted for storing said session data and user profile information; and

a processor coupled to said at least one port and said storage device, said processor adapted to execute commands to suspend said session at said first device, and reestablish said suspended session on a second device using said suspended session data.
