Abstract

A system for managing the operation of a plurality of radio modems integrated within the same wireless communication device. In at least one embodiment of the present invention, a control strategy may be employed to manage the operation of a plurality of radio modems and/or wireless mediums. A signal normally used to reactivate or “wake-up” system components in an inactive or sleep mode may also be employed to convey timing and/or control information to the system components of the wireless communication device.

Claims

1. A method, comprising:

receiving, in a multiradio controller, a signal relating to activity of one or more radio modems operating in a wireless network environment;

processing the signal received in the multiradio controller to interpret information contained in the received signal; and

utilizing the interpreted information to alter the behavior of the multiradio controller.

2. The method of claim 1, wherein the signal received by the multiradio controller is a wake-up signal transmitted by a radio modem contained in the same wireless communication device as the multiradio controller.

3. The method of claim 2, wherein the wake-up signal is used to change the multiradio controller from an inactive state to an active state.

4. The method of claim 1, wherein the information contained in the received signal is synchronization information.

5. The method of claim 4, wherein the synchronization information is related to slot/frame border markers for a wireless communication medium utilized by a radio modem contained in the same wireless communication device as the multiradio controller.

6. The method of claim 1, wherein the information contained in the received signal is control information.

7. The method of claim 6, wherein the control information indicates when the multiradio controller is required to operate and when the multiradio controller is no longer required to operate.

8. The method of claim 1, wherein utilizing the interpreted information includes at least one of synchronizing and controlling the multiradio controller based on information provided by a radio modem contained in the same wireless communication device.

9. A computer program product comprising a computer usable medium having computer readable program code embodied in said medium, comprising:

a computer readable program code for receiving, in a multiradio controller, a signal relating to activity of one or more radio modems operating in a wireless network environment;

a computer readable program code for processing the signal received in the multiradio controller to interpret information contained in the received signal; and

a computer readable program code for utilizing the interpreted information to alter the behavior of the multiradio controller.

10. The computer program product of claim 9, wherein the signal received by the multiradio controller is a wake-up signal transmitted by a radio modem contained in the same wireless communication device as the multiradio controller.

11. The computer program product of claim 10, wherein the wake-up signal is used to change the multiradio controller from an inactive state to an active state.

12. The computer program product of claim 9, wherein the information contained in the received signal is synchronization information.

13. The computer program product of claim 12, wherein the synchronization information is related to slot/frame border markers for a wireless communication medium utilized by a radio modem contained in the same wireless communication device as the multiradio controller.

14. The computer program product of claim 9, wherein the information contained in the received signal is control information.

15. The computer program product of claim 14, wherein the control information indicates when the multiradio controller is required to operate and when the multiradio controller is no longer required to operate.

16. The computer program product of claim 9, wherein utilizing the interpreted information includes at least one of synchronizing and controlling the multiradio controller based on information provided by a radio modem contained in the same wireless communication device.

17. A multiradio controller, comprising:

a communication module for receiving, in a multiradio controller, a signal relating to activity of one or more radio modems operating in a wireless network environment;

a computing module for processing the signal received in the multiradio controller to interpret information contained in the received signal, and utilizing the interpreted information to alter the behavior of the multiradio controller.

18. The controller of claim 17, wherein the signal received by the communication device is a wake-up signal transmitted by a radio modem contained in the same wireless communication device as the multiradio controller.

19. A method, comprising:

receiving, in one or more radio modems, a signal relating to activity of a controller;

processing the signal received in the one or more radio modems to interpret information contained in the received signal; and
