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. A method for processing a request for a white space channel assignment, the method comprising:

receiving, by a processor of an application server of a network service provider, the request for the white space channel assignment;

identifying, by the processor, a white space channel in accordance with the request;

sending, by the processor, a response to the request 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, wherein the plurality of users comprises the user; and

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

2. The method of claim 1, further comprising:

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

3. The method of claim 1, further comprising:

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

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

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

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

7. The method 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 an application server of a network service provider, cause the processor to perform operations for processing a request for a white space channel assignment, the operations comprising:

receiving the request for the white space channel assignment;

identifying a white space channel in accordance with the request;

sending a response to the request 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, wherein the plurality of users comprises the user; and

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

9. The non-transitory computer-readable storage medium of claim 8, further comprising:

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

10. The non-transitory computer-readable storage medium of claim 8, further comprising:

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

11. The non-transitory computer-readable storage medium of claim 8, wherein the request comprises a duration of transmission.

12. The non-transitory computer-readable storage medium of claim 8, wherein the request comprises a type of request.

13. The non-transitory computer-readable storage medium of claim 12, wherein the type of request comprises an extension request of a previous request.

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

15. A method for sending a request for a white space channel assignment, the method comprising:

sending, by a processor of a gateway, 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, by the processor of the gateway, 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.

16. The method of claim 15, wherein the response further comprises the time duration.

17. The method of claim 15, wherein the request comprises a bandwidth need.

18. The method of claim 16, further comprising:

sending, by the processor of the gateway, a second request for an extension of time after the time duration has elapsed.

19. The method of claim 18, further comprising:

receiving, by the processor of the gateway, a second response permitting the extension of time after the time duration has elapsed.

20. The method of claim 18, further comprising:

receiving, by the processor of the gateway, a second response denying the extension of time after the time duration has elapsed.
