Abstract

A wireless communication device uses operational parameters stored in a capabilities list to control operation of the device. The device may also provide auxiliary services, such as reception of broadcast television signals and location detection using network assisted GPS. When auxiliary services are selected, the cellular operation may cause interference with the auxiliary services. The wireless communication device includes a reduced set of capabilities to control operation of the wireless communication device when an auxiliary service is requested. The particular set of reduced capabilities may depend on the specific type of auxiliary service that has been requested. Upon termination of the auxiliary services, the full capabilities list may be restored and the operation of the wireless communication device is thereafter controlled by the full set of operational capabilities.

Claims

1. A device comprising:

a first receiver that communicates using a plurality of communication bands;

a first transmitter that communicates using the plurality of communication bands;

a second receiver that communicates using a first communication band of the plurality of communication bands, wherein the second receiver is selectively activated;

a data storage structure that stores data related to operational capabilities of the first receiver and the first transmitter, the operational capabilities comprising a set of communication bands of the plurality of communication bands on which the first receiver and the first transmitter can communicate when the second receiver is selectively activated; and

a controller that controls operation of the first receiver and the first transmitter by selecting a communication band from the set of communication bands based on the data in the data structure when the second receiver is selectively activated,

wherein the first receiver and the first transmitter communicate using an initial communication band of the plurality of communication bands when the second receiver is not activated, and

wherein the controller alters the initial communication band on which the first receiver and the first transmitter are communicating if the initial communication band is not one of the set of communication bands when the second receiver is activated.

2. The device in claim 1, wherein the controller further causes a re-registration process upon alteration of the initial communication band on which the first receiver and the first transmitter are communicating.

3. The device in claim 1, wherein the second receiver is part of an auxiliary transceiver.

4. The device in claim 1, wherein the data storage structure stores data related to operational capabilities including a signaling protocol, a transmission power level, and a bandwidth.

5. The device in claim 1, wherein the second receiver is contained within a housing containing the first transmitter and the first receiver.

6. The device in claim 1, wherein the second receiver receives signals from a global positioning system satellite.

7. A method comprising:

communicating, using a wireless communication device comprising a processor, using a plurality of communication bands;

determining, by the wireless communication device, that an auxiliary receiver in the wireless communication device is activated;

determining, by the wireless communication device, that the wireless communication device is not communicating on any of a set of communication bands of the plurality of communication bands on which the wireless communication device communicates when the auxiliary receiver is activated;

altering, by the wireless communication device, operation of the wireless communication device to communicate using one of the set of communication bands; and

re-registering, by the wireless communication device, the wireless communication device with a communications network using the one of the set of communication bands.

8. The method in claim 7, wherein the wireless communication device communicates using the one of the set of communication bands while the auxiliary device is activated.

9. The method in claim 7, further comprising determining that the auxiliary receiver is deactivated.

10. The method in claim 9, further comprising altering operation of the wireless communication device to communicate using the one of the set of communication bands.

11. The method in claim 7, wherein the auxiliary receiver is activated to receive broadcast television signals.

12. The method in claim 7, wherein the auxiliary receiver is activated to receive signals from a global positioning system satellite.

13. The method in claim 7, further comprising transmitting, to the communications network, data indicating operational capabilities of the first receiver and the first transmitter, including the one of the set of communication bands on which the first receiver and the first transmitter operate.

14. A non-transitory computer-readable medium having computer instructions stored thereon that, when executed by a processor, causes the processor to perform operations comprising:

determining that an auxiliary receiver of a wireless communication device that communicates using a plurality of communication bands is activated;

determining that the wireless communication device is not communicating on any of a set of communication bands of the plurality of communication bands on which the wireless communication device communicates when the auxiliary receiver is activated;

altering operation of the wireless communication device to communicate using one of the set of communication bands; and

re-registering the wireless communication device with a communications network using the one of the set of communication bands.

15. The computer-readable medium in claim 14, wherein the wireless communication device communicates using the one of the set of communication bands while the auxiliary device is activated.

16. The computer-readable medium in claim 14, wherein the execution of the computer instructions causes the processor to perform operations further comprising determining that the auxiliary receiver has been deactivated.

17. The method in claim 16, wherein the execution of the computer instructions causes the processor to perform operations further comprising altering operation of the wireless communication device to communicate using one of the plurality of communication bands.

18. The method in claim 14, wherein the auxiliary receiver is activated to receive broadcast television signals.

19. The method in claim 14, wherein the auxiliary receiver is activated to receive signals from a global positioning system satellite.

20. The method in claim 14, wherein the execution of the computer instructions causes the processor to perform operations further comprising transmitting, to the communications network, data indicating current operational capabilities of the first receiver and the first transmitter, including the one of the set of communication bands on which the first receiver and the first transmitter are operating.
