handle the first channel based on the specified first part of the frequency band, wherein
the primary communication service occupies a second part of the frequency band, and
the first part is different from the second part; and
a control unit configured to allocate, based on the primary communication service occupies the second part of the frequency band, the first part of the frequency band to a secondary use communication device, wherein
the secondary use communication device provides a secondary communication service, and
the secondary communication service is different from the primary communication service.
2. The first communication control device according to claim 1 , wherein the first information includes second information that corresponds to a detection result of the first channel occupied by the primary communication service.
3. The first communication control device according to claim 1 , wherein
a second communication control device acquires third information, and
the first information includes the third information that corresponds to a detection result of a second channel occupied by the primary communication service.
4. The first communication control device according to claim 3 , wherein
a specific database acquires the third information from the second communication control device, and
the acquisition unit is further configured to acquire the third information from the specific database.
5. The first communication control device according to claim 1 , wherein
a first device detects a first detection result of a second channel among the plurality of channels allocated to the primary communication service,
a second device detects a second detection result of a third channel among the plurality of channels allocated to the primary communication service,
the acquisition unit is further configured to acquire the first detection result and the second detection result,
the control unit is further configured to allocate, based on the acquired first detection result and the second detection result, a fourth channel among the plurality of channels to the secondary use communication device, and
the fourth channel is not included in either the first detection result or the second detection result.
6. The first communication control device according to claim 1 , wherein the control unit is further configured to allocate the first part of the frequency band to the secondary use communication device based on a capability related to frequency band allocation of the secondary use communication device.
7. The first communication control device according to claim 6 , wherein the control unit is further configured to allocate at least a part of the first part of the frequency band to the secondary use communication device based on the capability.
8. The first communication control device according to claim 6 , wherein
the control unit is further configured to determine, based on capability of each secondary use communication device of a plurality of secondary use communication devices, the secondary use communication device to which the first part of the frequency band is allocated, and
the plurality of secondary use communication devices includes the secondary use communication device.
9. The first communication control device according to claim 6 , wherein the acquisition unit is further configured to acquire information of the capability from the secondary use communication device.
10. The first communication control device according to claim 1 , further comprising a notification unit configured to notify the secondary use communication device of fourth information that corresponds to an allocation result of the first part of the frequency band.
11. A communication device, comprising:
a notification unit configured to notify a communication control device of a request related to allocation of a first part of a frequency band to the communication device, wherein
the frequency band corresponds to a channel, occupied by a primary communication service, among a plurality of channels allocated to the primary communication service,
the primary communication service occupies a second part of the frequency band, and
the first part is different from the second part; and
an acquisition unit configured to acquire, based on the primary communication service occupies the second part of the frequency band, information that corresponds to the allocation of the first part of the frequency band to the communication device.
12. The communication device according to claim 11 , wherein the notification unit is further configured to notify the communication control device of information of capability related to frequency band allocation of the communication device.
13. The communication device according to claim 12 , wherein the acquisition unit is further configured to acquire the information that corresponds to the capability.
14. A communication control method comprising:
acquiring first information of a first channel occupied by a primary communication service among a plurality of channels allocated to the primary communication service;
specifying a first part of a frequency band based on the acquired first information, wherein
the frequency band corresponds to the first channel; and
handling the first channel based on the specified first part of the frequency band, wherein
the primary communication service occupies a second part of the frequency band, and
the first part is different from the second part; and
allocating, based on the primary communication service occupies the second part of the frequency band, the first part of the frequency band to a secondary use communication device, wherein
the secondary use communication device provides a secondary communication service, and
the secondary communication service is different from the primary communication service.
