Intel Execs: Cloud Spectrum Broker Could Tackle Wireless Data Explosion

Several current and former Intel executives are named as inventors on a patent published Thursday that contains a blueprint a “cloud spectrum service system” that would link spectrum holders, a global broker and content providers.

While Intel isn’t yet named on the application, Mohamad El-Refaey, its lead software architect, is named as the lead inventor.

“The world is heading to a global spectrum shortage triggered by the wireless data explosion,” El-Refaey notes in the patent application. “There is a worldwide push for regulations that allow licensed spectrum holders to rent their un-used or under-utilized spectrum to other entities with a desire to use the spectrum. This creates a win-win situation where, for example mobile operators get access to spectrum they otherwise would not have, while the spectrum holders with un-used spectrum get some form of compensation. This is particularly attractive to the licensed spectrum holders (non-cellular) who may be underutilizing their spectrum but cannot relinquish the spectrum (say by selling it in the secondary market) since they have use for it in certain areas or at certain times.”

Abstract: A device for use in a mobile communication user equipment includes processing circuitry to prepare a spectrum allocation request for requesting extra spectrum according to a predetermined protocol; send the spectrum allocation request to a cloud spectrum broker; and receive a response to the spectrum allocation from the cloud spectrum broker. A device for use in a cloud spectrum broker, the device comprising processing circuitry to receive from a user equipment an allocation request, the allocation request for requesting extra spectrum, the allocation request according to a predetermined protocol; determine a response to the allocation request; and send the response to the user equipment.

Patent Application

Claims: 

1. A device for use in a mobile communication user equipment, UE, the device comprising processing circuitry to: prepare a spectrum allocation request for requesting extra spectrum according to a predetermined protocol; send the spectrum allocation request to a cloud spectrum broker; and receive a response to the spectrum allocation from the cloud spectrum broker.

2. The device of claim 1, wherein the processing circuitry is to send further information to the cloud spectrum broker, the further information including at least one of: an indication of a mobility model for the requested extra spectrum, an indication of a radio interface for the requested extra spectrum, authorization information associated with the spectrum allocation request, a put price.

3. The device of claim 2, wherein the processing circuitry is to prepare the further information according to the predetermined protocol before sending the further information to the cloud spectrum broker.

4. The device of claim 1, wherein the processing circuitry is further to receive an acknowledgement from the cloud spectrum broker in response to the spectrum allocation request.

5. The device of claim 1, wherein the processing circuitry is further to receive, from the cloud spectrum broker, a list of available networks for providing the requested extra spectrum.

6. The device of claim 1, wherein the processing circuitry is further to receive, from the cloud spectrum broker, an indication of a spectrum window for providing the requested extra spectrum.

7. A user equipment comprising: the device of claim 1; and one or more of: a screen, a speaker, a touchscreen, a keyboard, an antenna array including a plurality of antennas, a graphics processor, an application processor.

8. A method of requesting extra spectrum, the method comprising: determining that extra spectrum should be requested; determining information to be sent in an allocation request, the allocation request for requesting allocation extra spectrum; and sending the allocation request to a cloud spectrum broker, the allocation request being sent according to a predetermined protocol.

9. The method of claim 8, wherein the method further comprises sending to the cloud spectrum broker at least one of: an indication of a mobility model for the requested extra spectrum, an indication of a radio interface for the requested extra spectrum, authorization information associated with the allocation request, a put price.

10. The method of claim 8, wherein the processing circuitry is further to receive from the cloud spectrum broker at least one of: an acknowledgement in response to the allocation request, a list of available networks for providing the requested extra spectrum, an indication of a spectrum window for providing the requested extra spectrum.

11. A device for use in a cloud spectrum broker, the device comprising processing circuitry to: receive from a user equipment an allocation request, the allocation request for requesting extra spectrum, the allocation request according to a predetermined protocol; determine a response to the allocation request; and send the response to the user equipment.

12. The device of claim 11, wherein the response to the user equipment is according to the predetermined protocol.

13. The device of claim 11, wherein the allocation request includes at least one of: an indication of a mobility model for the requested extra spectrum, an indication of a radio interface for the requested extra spectrum, authorization information associated with the allocation request, a put price.

14. The device of claim 11, wherein the processing circuitry is to send a request for spectrum to a global broker; receive a response to request for spectrum from the global broker; and determine the response to the allocation request based on the response to the request for spectrum.

15. The device of claim 11, wherein the response to the user equipment includes at least one of: an acknowledgement in response to the allocation request, a list of available networks for providing the requested extra spectrum, an indication of a spectrum window for providing the requested extra spectrum.

16. A non-transitory storage machine-readable storage medium having stored thereon instructions that, when executed by a computer, cause the computer to perform the method of claim 8
