COMMUNICATION CONTROL DEVICE, COMMUNICATION CONTROL METHOD, COMMUNICATION SYSTEM AND COMMUNICATION DEVICE
First Claim
1. A communication control device which controls communication of one or more secondary usage nodes respectively providing second communication services using a part of a frequency band assigned to a first communication service, the communication control device comprising:
- a communication unit that receives access technique information indicating radio access techniques usable by the corresponding secondary usage nodes from the respective secondary usage nodes;
a storage unit that stores the access technique information received by the communication unit; and
a control unit that, when at least a portion of a service area of a second-order second communication service is included in a service area of a first-order second communication service, determines whether or not at least a part of communication resources can be shared between the first-order second communication service and the second-order second communication service on the basis of the radio access techniques of the first-order second communication service and the second-order second communication service indicated by the access technique information.

13. A communication system which includes a plurality of secondary usage nodes respectively providing second communication services using a part of a frequency band assigned to a first communication service and a communication control device controlling communication of the plurality of secondary usage nodes,
wherein each of the secondary usage nodes includes: -
a communication unit that transmits access technique information indicating radio access techniques usable by the corresponding secondary usage nodes to the communication control device, and wherein the communication control device includes; a communication unit that receives the access technique information from the respective secondary usage nodes; a storage unit that stores the access technique information received by the communication unit; and a control unit that, when at least a portion of a service area of a second-order second communication service is included in a service area of a first-order second communication service, determines whether or not at least a part of communication resources can be shared between the first-order second communication service and the second-order second communication service on the basis of the radio access techniques of the first-order second communication service and the second-order second communication service indicated by the access technique information.

14. A communication device which provides a second communication service using a part of a frequency band assigned to a first communication service, the communication device comprising:
-
a communication unit that transmits access technique information indicating a radio access technique usable by the communication device to another device in order to cause the other device to determine whether or not it is necessary to share a part of communication resources of the second communication service with another second communication service; and a secondary usage control unit that specifies a range of communication resources sharable with the other second communication service in response to a request from the other device when the other device determines that a service area of the second communication service includes a service area of the other second communication service, and it is necessary to share a part of the communication resources of the second communication service on the basis of the access technique information.
