Abstract

A method and an apparatus for providing channel sharing are disclosed. For example, the method receives a request for a white space channel assignment, and identifies one or more white space channels in accordance with the request. The method sends a response to the request comprising a white space channel assignment, wherein the white space channel assignment assigns one of the identified one or more white space channels.

Claims

1. An application server of a network service provider comprising:

a processor; and

a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising;

receiving a request for a white space channel assignment;

identifying a white space channel in accordance with the request;

sending a response to the request, the response comprising the white space channel assignment, wherein the white space channel assignment assigns a timeslot of the white space channel that is identified for sharing the white space channel, wherein the white space channel that is identified is used by a plurality of users; and

releasing the white space channel in accordance with an elapsed time period associated with the timeslot that has been assigned.

2. The application server of claim 1, the operations further comprising:

updating a database in accordance with the releasing of the white space channel.

3. The application server of claim 1, the operations further comprising:

updating a database in accordance with the white space channel assignment of the white space channel.

4. The application server of claim 1, wherein the request comprises a duration of transmission.

5. The application server of claim 1, wherein the request comprises a type of request.

6. The application server of claim 5, wherein the type of request comprises an extension request of a previous request.

7. The application server of claim 1, wherein the request comprises a bandwidth need.

8. A non-transitory computer-readable storage medium storing a plurality of instructions which, when executed by a processor of a gateway, cause the processor to perform operations for sending a request for a white space channel assignment, the operations comprising:

sending the request for the white space channel assignment, wherein the request is sent to a network service provider, wherein the gateway is located at a local location of a user, wherein the gateway is for coordinating a use of the white space channel assignment to support a plurality of devices to communicate wirelessly at the local location of the user; and

receiving a response to the request, where the response comprises a white space channel that is available based on a location of the gateway and a timeslot for sharing the white space channel, wherein the timeslot is associated with the white space channel that is available, wherein the white space channel that is available is used by a plurality of users, wherein the plurality of users comprises the user, wherein the white space channel is released in accordance with an elapsed time period associated with a time duration assigned to the timeslot.

9. The non-transitory computer-readable storage medium of claim 8, wherein the response further comprises the time duration.

10. The non-transitory computer-readable storage medium of claim 9, the operations further comprising:

sending a second request for an extension of time after the time duration has elapsed.

11. The non-transitory computer-readable storage medium of claim 10, the operations further comprising:

receiving a second response permitting the extension of time after the time duration has elapsed.

12. The non-transitory computer-readable storage medium of claim 10, the operations further comprising:

receiving a second response denying the extension of time after the time duration has elapsed.

13. The non-transitory computer-readable storage medium of claim 8, wherein the request comprises a bandwidth need.

14. A gateway comprising:

a processor; and

a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising;

sending a request for a white space channel assignment, wherein the request is sent to a network service provider, wherein the gateway is located at a local location of a user, wherein the gateway is for coordinating a use of the white space channel assignment to support a plurality of devices to communicate wirelessly at the local location of the user; and

receiving a response to the request, where the response comprises a white space channel that is available based on a location of the gateway and a timeslot for sharing the white space channel, wherein the timeslot is associated with the white space channel that is available, wherein the white space channel that is available is used by a plurality of users, wherein the plurality of users comprises the user, wherein the white space channel is released in accordance with an elapsed time period associated with a time duration assigned to the timeslot.

15. The gateway of claim 14, wherein the response further comprises the time duration.

16. The gateway of claim 15, the operations further comprising:

sending a second request for an extension of time after the time duration has elapsed.

17. The gateway of claim 16, the operations further comprising:

receiving a second response permitting the extension of time after the time duration has elapsed.

18. The gateway of claim 16, the operations further comprising:

receiving a second response denying the extension of time after the time duration has elapsed.

19. The gateway of claim 14, wherein the request comprises a bandwidth need.
