Abstract

The present invention provides a mobile terminal capable of supporting both wired and local wireless interfaces to support communications. When a connection to a network via the wired interface is available, the mobile terminal will establish sessions via the wired interface. If communications via the wired interface are not possible, communications are established via the local wireless interface or an optional cellular interface. If existing communications via the wired interface are no longer possible, a new session may be established via the local wireless interface to continue the prior communication. In case of such an event, the communications will be associated with a particular ID, which is used when establishing the new session such that the original communication may continue over the new session.

Claims

1. A mobile terminal comprising:

a) a first interface adapted to facilitate communications via a wired connection to a first communication network;

b) a second interface adapted to facilitate local wireless communications via a second communication network; and

c) a control system operatively associated with the first and second interfaces and adapted to;

i) establish communication sessions over the first and second communication networks via the first and second interfaces; and

ii) select the first interface for establishing the communication sessions over the first communication network, when the wired connection via the first interface is available.

2. The mobile terminal of claim 1 wherein the control system is further adapted to determine if the wired connection via the first interface is available.

3. The mobile terminal of claim 1 wherein communications via the first interface are associated with a first address and communications via the second interface are associated with a second address.

4. The mobile terminal of claim 3 wherein the control system is further adapted to register with a service node in association with the first address when the wired connection via the first communication interface is available.

5. The mobile terminal of claim 4 wherein the control system is further adapted to register with the service node in association with the second address when the wired connection via the first interface is not available.

6. The mobile terminal of claim 4 wherein the control system is further adapted to register with the service node in association with the second address prior to the wired connection via the first interface becoming unavailable.

7. The mobile terminal of claim 4 wherein the control system is further adapted to register with the service node in association with the second address prior to initiating local wireless communications via the second interface.

8. The mobile terminal of claim 3 wherein the control system is further adapted to obtain the first address after detecting an ability to communicate via the first communication interface, and obtain the second address after detecting an ability to communicate via the second communication interface.

9. The mobile terminal of claim 1 wherein the first communication interface is a docking interface adapted to couple to a docking station, which connects to the first communication network such that the wired connection is facilitated through the docking station.

10. The mobile terminal of claim 9 wherein the first communication interface further comprises a network interface coupled to the docking interface.

11. The mobile terminal of claim 9 wherein the docking station comprises a network interface.

12. The mobile terminal of claim 1 wherein the control system is further adapted to:

a) establish a first session for a communication with an entity via the first interface, the first session identified with first indicia associated with the communication;

b) determine communications via the first interface will no longer be possible; and

c) initiate and establish a second session for the communication with the entity via the second interface, the second session identified with the first indicia.

13. The mobile terminal of claim 12 wherein to determine communications via the first interface will no longer be possible, the control system is adapted to detect being removed from a docking station, which is coupled to the first communication network.

14. The mobile terminal of claim 12 wherein to determine communications via the first interface will no longer be possible, the control system is adapted to detect being removed from being directly coupled to the first communication network.

15. The mobile terminal of claim 12 wherein to determine communications via the first interface will no longer be possible, the control system is adapted to detect a signal sent from a docking station, which is coupled to the first communication network and coupled to the mobile terminal.

16. The mobile terminal of claim 12 wherein the control system is further adapted to:

a) determine communications via the first interface are available; and

b) initiate and establish a third session for the communication with the entity via the first interface, the third session for the communication identified with the first indicia.

17. The mobile terminal of claim 12 wherein the first session is associated with a first address for the mobile terminal and the second session is associated with a second address for the mobile terminal.

18. The mobile terminal of claim 1 further comprising a cellular interface operatively associated with the control system to facilitate cellular communications.

19. A method comprising:

a) providing a first interface adapted to facilitate communications via a wired connection to a first communication network;

b) providing a second interface adapted to facilitate local wireless communications via a second communication network;

c) establishing communication sessions over the first and second communication networks via the first and second network interfaces; and

d) selecting the first interface for establishing the communication sessions over the first communication network, when the wired connection via the first interface is available.

20. The method of claim 19 further comprising determining the wired connection via the first interface is available.

21. The method of claim 19 wherein communications via the first interface are associated with a first address and communications via the second interface are associated with a second address.

22. The method of claim 21 further comprising registering with a service node in association with the first address when the wired connection via the first communication interface is available.

24. The method of claim 22 further comprising registering with the service node in association with the second address prior to the wired connection via the first interface becoming unavailable.

25. The method of claim 22 further comprising registering with the service node in association with the second address prior to initiating local wireless communications via the second interface.

26. The method of claim 21 further comprising obtaining the first address after detecting an ability to communicate via the first communication interface, and obtaining the second address after detecting an ability to communicate via the second communication interface.

27. The method of claim 19 wherein the first communication interface is a docking interface adapted to couple to a docking station, which connects to the first communication network such that the wired connection is facilitated through the docking station.

28. The method of claim 27 further comprising providing a network interface coupled to the docking interface.
