Abstract

A method for selecting a mobile communication service such as an air interface and/or communication system can include selecting the communication service based on motion and/or location. The selection of communication system can be made to optimize the user experience based on the type of service required and the environment the mobile station is in. Additionally, within an air interface, service can be chosen based on the type of call and the environment that mobile communication device is in.

Claims

1. A mobile communication device comprising:

a processor,

a memory coupled to the processor;

a transceiver coupled to the processor, the processor further configured to;

engage in a communication using a first communication system;

determine whether the mobile communication device is in motion;

when the device is in motion, determine motion information for the device,

determine if another communication system is preferable based on the motion information; and

when it is determined that another communication system is preferable, switch to the other communication system.

2. The mobile communication device of claim 1, wherein the determination of motion step comprises using global positioning system signals to determine that the mobile communication device is in motion.

3. The mobile communication device of claim 2, wherein using global positioning system signals comprises processing the signals within the mobile communication device.

4. The mobile communication device of claim 2, wherein using global positioning system signals comprises processing the signals with assistance from a communication network.

5. The mobile communication device of claim 2, wherein using global positioning system signals comprises:

processing the signals within the mobile communication device; and

,

processing the signals with assistance from a communication network.

6. The mobile communication device of claim 1, wherein the determination of motion step comprises using a plurality of position fixes to determine that the mobile communication device is in motion.

7. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises using an expanded preferred roaming list including geographical information.

8. The mobile communication device of claim 1, wherein the determination of motion comprises a determination of position, bearing, and velocity.

9. The mobile communication device of claim 1, wherein the processor is further configured to:

predict a future location; and

,

schedule the switching to another communication system step based on the predicted future location.

10. The mobile communication device of claim 1, wherein the switching step comprises a handoff.

11. The mobile communication device of claim 10, wherein the handoff is delayed based on a prediction of a future location of the mobile communication device.

12. The mobile communication device of claim 1, wherein the determine if another communication system is preferable step comprises determining if another communication system is preferable for one of a voice communication, a data communication, and for a voice over internet protocol communication.

13. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining if another communication system is preferable for Quality of Service (QoS).

14. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on available data rates on each of the first and second communication systems.

15. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on availability of the first and second communication systems.

16. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on access rights on each of the first and second communication systems.

17. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on cost of service.

18. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on minutes remaining on the present service.

19. The mobile communication device of claim 1, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on a roaming partner agreement.

20. A method for managing system access of a mobile communication device comprising, the method comprising:

engaging in a communication using a first communication system;

determining whether the mobile communication device is in motion;

when the device is in motion, determining motion information for the device;

determining if another communication system is preferable based on the motion information; and

when it is determined that another communication system is preferable, switching to the other communication system.

21. The method of claim 20, wherein the determination of motion step comprises using a plurality of position fixes to determine that the mobile communication device is in motion.

22. The method of claim 20, wherein the determination that another communication system is preferable step comprises using an expanded preferred roaming list including geographical information.

23. The method of claim 20, wherein the determination of motion comprises a determination of position, bearing, and velocity.

24. The method of claim 20, further comprising:

predicting a future location; and

scheduling the switching to another communication system step based on the predicted future location.

25. The method of claim 20, wherein the determine if another communication system is preferable step comprises determining if another communication system is preferable for one of a voice communication, a data communication, and for a voice over internet protocol communication.

26. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining if another communication system is preferable for Quality of Service (QoS).

27. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on available data rates on each of the first and second communication systems.

28. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on availability of the first and second communication systems.

29. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on access rights on each of the first and second communication systems.

30. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on cost of service.

31. The method of claim 20, wherein the determination that another communication system is preferable step comprises determining the preferable communication system based on a roaming partner agreement.
