Abstract

A system and method are disclosed for scanning services with a multimode communication device. A system that incorporates teachings of the present disclosure may include, for example, a communication device (102) having a controller (206) for managing operations of a user interface (UI) (204), and a wireless transceiver (202). The UI conveys messages to an end user and facilitates manipulating operations of the communication device. The wireless transceiver supports software defined radio (SDR) communications and communications on at least one other access technology. The controller is programmed to scan (312, 314) for services in a television (TV) spectrum and at least one among a cellular spectrum, an ultra wideband (UWB) spectrum, a WiFi spectrum and a WiMax spectrum, detect (316) one or more services, and present (318) one or more of the detected services to the end user. Additional embodiments are disclosed.

Claims

1. A communication device, comprising:

a memory for storing computer instructions;

a user interface;

a wireless transceiver; and

a controller coupled to the memory, the user interface, and the wireless transceiver, wherein the controller manages operations of the user interface, and the wireless transceiver, wherein the user interface conveys messages to an end user and facilitates manipulating operations of the communication device, and wherein the wireless transceiver supports software defined radio communications and communications on at least one other access technology, and wherein when executing the computer instructions, the controller is configured to;

receive on a control channel signaling software for scanning portions of a television spectrum, wherein the control channel operates in a portion of the television spectrum;

scan for services in the television spectrum according to the received signaling software, and at least one among a cellular spectrum, an ultra wideband spectrum, a wireless fidelity spectrum and a worldwide interoperability for microwave access spectrum;

detect one or more services in the television spectrum; and

select one of the detected one or more services in the television spectrum according to a data rate to cost of service ratio determined for each of the detected one or more services in the television spectrum.

2. The communication device of claim 1, wherein when executing the computer instructions, the controller is configured to:

establish one or more service preferences from a group of preference criteria comprising cost of service, quality of service, radio frequency signal strength of a base station, communication range of the base station relative to a location of the communication device, and hand-off capabilities of neighboring base stations; and

scan for services according to the one or more preferences.

3. The communication device of claim 2, wherein the one or more service preferences are grouped according to a select one or more end user profiles comprising a stationary end user profile, a mobile end user profile, an economic end user profile, and a data centric end user profile.

4. The communication device of claim 1, wherein when executing the computer instructions, the controller is configured to:

receive information in the control channel indicating available services in the television spectrum; and

scan for services in the television spectrum according to the control channel information.

5. The communication device of claim 1, wherein the television spectrum is selected from at least one among a group of frequency bands comprising 54-72 MHz, 76-88 MHz, 174-216 MHz, and 470-806 MHz.

6. The communication device of claim 1, wherein when executing the computer instructions, the controller is configured to:

establish a buddy list of one or more other communication devices; and

detect a presence of one or more of the buddy list communication devices in the television spectrum.

7. The communication device of claim 6, wherein when executing the computer instructions, the controller is configured to prevent other communication devices roaming in the television spectrum from detecting a presence of the communication device.

8. The communication device of claim 1, wherein the services comprise at least two of a full-duplex voice service, a half-duplex voice service, a location service, a video service, a text messaging service, or an instant messaging service.

9. A non-transitory computer-readable storage medium in a communication device, comprising computer instructions, which when executed by at least one processor, cause the at least one processor to perform operations comprising:

identifying a service preference, wherein the service preference is based on a comparison between a quality of service offering and cost of service offering of a network;

receiving on a control channel signaling software for scanning portions of a television spectrum, wherein the control channel operates in a portion of the television spectrum;

scanning for services in the television spectrum according to the received signaling software, and at least one among ultra wideband, wireless fidelity, worldwide interoperability for microwave access or cellular wireless access technologies;

detecting one or more services in the television spectrum; and

selecting one of the detected one or more services according to the service preference.

10. The storage medium of claim 9, wherein the computer instructions cause the at least one processor to perform operations comprising:

receiving information from the control channel indicating available services in the television spectrum; and

scanning for services in the television spectrum according to the control channel information.

11. The storage medium of claim 9, wherein the computer instructions cause the at least one processor to perform operations comprising:

monitoring a use behavior of services by an end user;

identifying the service preference from the monitored use behavior; and

scanning for services in the television spectrum according to the service preference.

12. The storage medium of claim 9, wherein the computer instructions cause the at least one processor to perform operations comprising:

establishing a buddy list of one or more other communication devices;

detecting in the selected service a presence of one or more of the communication devices in the buddy list;

presenting to the end user the one or more detected communication devices;

receiving from the end user a selection of one or more of the detected communication devices; and

establishing communication with the selected communication devices.

13. The storage medium of claim 12, wherein the computer instructions cause the at least one processor to perform operations comprising preventing other communication devices roaming in the television spectrum from detecting a presence of the communication device in response to a privacy selection by the end user.

14. The storage medium of claim 9, wherein the selected service is one of a full-duplex voice service, a half-duplex voice service, a location service, a video service, a text messaging service, or an instant messaging service.

15. A base station, comprising:

a wireless transceiver supporting software defined radio communications in an unlicensed television spectrum and communication services in at least one other access technology;

a memory for storing computer instructions; and

a controller coupled to the memory and the wireless transceiver, wherein when executing the computer instructions, the controller is configured to;

offer services in the unlicensed television spectrum and the at least one other access technology;

receive a service request from a communication device to scan the unlicensed television spectrum and the other access technology; and

transmit over a control channel a software defined radio software application to the communication device to enable scanning of the unlicensed television spectrum, wherein the control channel operates in a portion of the unlicensed television spectrum, wherein the communication device selects one of the services in the unlicensed television spectrum and the at least one other access technology according to a comparison between a quality of service offering and a cost of service offering of each service.
