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 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 the 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.

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, wherein the request for resources comprises 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 or transmit data traffic.

5. The method of claim 1, wherein the requested resources comprises at least one of hardware resources, radio frequency resources, or power resources.

6. The method of claim 5, wherein the requested 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 5, wherein the requested resources comprise at least one of a receiver chain component, a transmitter chain component, an antenna, or a frequency assignment.

8. The method of claim 5, wherein the requested resources comprise at least one of battery power or available transmit power.

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

communicating at a first frequency;

receiving data indicative of one or more second frequencies;

determining which of the one of more second frequencies is within a predetermined bandwidth of the first frequency; and

concurrently communicating at the first frequency and at least a portion of the determined second frequencies.

10. The method of claim 9, further comprising selecting at least one of the determined second frequencies, wherein communicating at at least a portion of the determined second frequencies comprises communicating at the selected second frequencies.

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

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

a processor configured to receive a request for 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 resources for the second air interface,

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

12. The device of claim 11, 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.

13. The device of claim 11, wherein the processor is configured to receive a request for resources for at least one of:

the processor, an antenna, a transceiver, a modem, or an input device.

14. The device of claim 11, wherein the transceiver is configured by to processor to communicate over the first or second air interface.

15. The device of claim 11, 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.

16. The device of claim 15, 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.

17. The device of claim 11, wherein the first air interface supports voice traffic and the second air interface supports data traffic.

18. The device of claim 11, wherein the first air interface is a voice interface and the second air interface is a data only interface.

19. The device of claim 11, wherein the request for resources comprises 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 or transmit data traffic.
