Abstract

[Object] A mechanism in which an allocated frequency can be shared among high-priority wireless networks is provided.

[Solution] A communication control device including: a management unit configured to manage one or more first wireless communication devices; and an information exchange unit configured to exchange, with another communication control device that manages one or more second wireless communication devices, information related to frequency sharing by the second wireless communication devices. The information related to frequency sharing includes information related to a frequency band in which high-priority access can be made.

Claims

1. A communication control device comprising:

a management unit configured to manage one or more first wireless communication devices; and

an information exchange unit configured to exchange, with another communication control device that manages one or more second wireless communication devices, information related to frequency sharing by the second wireless communication devices, wherein

the information related to frequency sharing includes information related to a frequency band in which high-priority access can be made.

2. The communication control device according to claim 1, wherein

the information related to frequency sharing includes information for utilizing the frequency band in which high-priority access can be made.

3. The communication control device according to claim 1, wherein

the information related to frequency sharing is associated with a geographical range.

4. The communication control device according to claim 1, wherein

the information related to frequency sharing includes information related to a right for high-priority access.

5. The communication control device according to claim 4, wherein

the information related to frequency sharing includes information related to a frequency band for which the right has been acquired.

6. The communication control device according to claim 4, wherein

the information related to frequency sharing includes information related to a frequency band for which the right is being exercised.

7. The communication control device according to claim 1, wherein

the other communication control device is operated by a business operator different from the communication control device.

8. The communication control device according to claim 1, further comprising:

a finding unit configured to find the other communication control device that manages the second wireless communication device existing around the first wireless communication device.

9. The communication control device according to claim 8, wherein

the information related to frequency sharing includes information related to carrier aggregation of a frequency band that the first wireless communication device provides and a frequency band that the second wireless communication device provides by frequency sharing.

10. The communication control device according to claim 9, wherein

the information related to frequency sharing includes a message requesting the second wireless communication device to make the frequency band for carrier aggregation available by frequency sharing.

11. The communication control device according to claim 1, further comprising:

a negotiation unit configured to acquire a right for high-priority access from a frequency management device, wherein

a frequency band for which the right for high-priority access acquired by the negotiation unit is exercised is utilized by the second wireless communication device.

12. The communication control device according to claim 11, wherein

the frequency band utilized by the second wireless communication device is a frequency band whose rate of utilization by the first wireless communication device is low.

13. The communication control device according to claim 11, wherein

the frequency band utilized by the second wireless communication device is a frequency band not utilized as a primary cell of carrier aggregation by the first wireless communication device.

14. The communication control device according to claim 1, wherein

the information related to frequency sharing includes a request from the other communication control device to the communication control device for causing the second wireless communication device to utilize a frequency band in which high-priority access can be made.

15. The communication control device according to claim 14, wherein

the information related to frequency sharing includes information indicating a geographical position of the second wireless communication device.

16. The communication control device according to claim 14, wherein

the information related to frequency sharing includes information indicating whether the second wireless communication device is installed indoors or outdoors.

17. The communication control device according to claim 1, wherein

the information related to frequency sharing includes a request from the communication control device to the other communication control device for causing the second wireless communication device to utilize a frequency band in which high-priority access can be made.

18. A communication control method comprising:

managing one or more first wireless communication devices by a processor; and

with another communication control device that manages one or more second wireless communication devices, exchanging, by an information exchange unit, information related to frequency sharing by the second wireless communication devices, wherein

the information related to frequency sharing includes information related to a frequency band in which high-priority access can be made.

19. A program for causing a computer to function as a communication control device comprising:

a management unit configured to manage one or more first wireless communication devices; and

an information exchange unit configured to exchange, with another communication control device that manages one or more second wireless communication devices, information related to frequency sharing by the second wireless communication devices, wherein

the information related to frequency sharing includes information related to a frequency band in which high-priority access can be made.

20. A wireless communication device comprising:

a processing unit configured to transmit a message requesting exchange of information for carrying out carrier aggregation through use of a frequency band provided by frequency sharing by another wireless communication device to a communication control device that manages the wireless communication device, the information being related to the frequency sharing between the communication control device and another communication control device that manages the other wireless communication device.
