Abstract

A device and method for resolving conflicts between air interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises communicating over a first air interface, receiving a request for resources for concurrent use in communicating over a second air interface, determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested resources for the second air interface, and concurrently communicating over the first air interface using resources for the first air interface and communicating over the second air interface using at least a portion of the requested resources for the second air interface.

Claims

1. A method of resolving conflicts between two air interfaces, the method comprising:

communicating over a first air interface;

receiving a request for power resources for concurrent use in communicating over a second air interface;

determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested power resources for the second air interface; and

concurrently communicating over the first air interface using resources for the first air interface and communicating over the second air interface using at least a portion of the requested power resources for the second air interface.

2. The method of claim 1, wherein the first air interface supports voice traffic and the second air interface supports data traffic.

3. The method of claim 1, wherein the first air interface is a voice interface and the second air interface is a data only interface.

4. The method of claim 1, further comprising receiving a request for radio frequency resources for concurrent use in communicating over the second air interface, wherein the request for radio frequency resources includes at least one of:

a traffic channel assignment, instructions to hand-off, instructions to perform a frequency search, call-redirection instructions, a request to receive data traffic, or a request to transmit data traffic.

5. The method of claim 1, further comprising receiving a request for hardware resources for concurrent use in communicating over the second air interface.

6. The method of claim 5, wherein the hardware resources comprise at least one of memory space of a memory, processing power of a processor, or bandwidth of one or more buses.

7. The method of claim 1, wherein the request for power resources includes a request for battery power.

8. The method of claim 1, wherein the request for power resources includes a request for available transmit power.

9. A device comprising:

a transceiver configured to communicate over a first air interface; and

a processor configured to;

receive a request for power resources for concurrent use in communicating over a second air interface; and

determine that a conflict does not exist between resources for the first air interface and at least a portion of the requested power resources for the second air interface,

wherein the transceiver is further configured to concurrently communicate over the first air interface using resources for the first air interface and communicate over the second air interface using at least the portion of the requested power resources for the second air interface.

10. The device of claim 9, wherein the transceiver comprises a first transceiver configured to communicate over the first air interface and a second transceiver configured to communicate over the second air interface.

11. The device of claim 9, wherein the transceiver is configured to communicate over the first air interface at a first frequency and configured to communicate over the second air interface at a second frequency within a predetermined bandwidth of the first frequency.

12. The device of claim 11, wherein the processor is configured to determine if a second frequency is within the predetermined bandwidth of the first frequency prior to communication over the second air interface.

13. The device of claim 9, wherein the processor is further configured to receive a request for radio frequency resources that includes at least one of:

a traffic channel assignment, instructions to hand-off, instructions to perform a frequency search, call-redirection instructions, a request to receive data traffic, or a request to transmit data traffic.

14. The device of claim 9, wherein the processor is further configured to receive a request for hardware resources.

15. The device of claim 9, wherein the request for power resources includes a request for battery power.

16. The device of claim 9, wherein the request for power resources includes a request for available transmit power.

17. The device of claim 9, wherein the processor is further configured to:

receive a request for radio frequency (RF) resources for concurrent use in communicating over the second air interface; and

determine whether the requested RF resources correspond to a frequency channel outside of a supported bandwidth of the first air interface.

18. The device of claim 17, wherein the transceiver is further configured to operate in a hybrid mode in response to a determination that the requested RF resources correspond to a frequency channel outside of the supported bandwidth of the first air interface.

19. The device of claim 18, wherein, during hybrid mode operation, the transceiver selectively switches between communicating over the first air interface and communicating over the second air interface.

20. The device of claim 17, wherein the transceiver is further configured to concurrently communicate over the first air interface at a first frequency within the supported bandwidth and over the second air interface at a second frequency within the supported bandwidth in response to a determination that the requested RF resources do not correspond to a frequency channel outside of the supported bandwidth of the first air interface.

21. The device of claim 9, wherein voice traffic is communicated over the first air interface and wherein the processor is further configured to:

receive a request to communicate data traffic over the first air interface;

determine whether the second air interface is better suited for communication of the data traffic than the first air interface; and

deny the request to communicate data traffic over the first air interface in response to a determination that the second air interface is better suited for communication of the data traffic.

22. A device for resolving conflicts between two air interfaces, the device comprising:

means for communicating over a first air interface;

means for receiving a request for power resources for concurrent use in communicating over a second air interface;

means for determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested power resources for the second air interface; and

means for concurrently communicating over the first air interface using the resources for the first air interface and communicating over the second air interface using at least the portion of the requested power resources for the second air interface.

23. A computer chip encoded with instructions for executing a method of resolving conflicts between two air interfaces, the method comprising:

communicating over a first air interface;

receiving a request for power resources for concurrent use in communicating over a second air interface;

determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested power resources for the second air interface; and

concurrently communicating over the first air interface using the resources for the first air interface and communicating over the second air interface using at least the portion of the requested power resources.
