Title:
COMMUNICATION CONTROL DEVICE, COMMUNICATION CONTROL METHOD, COMMUNICATION SYSTEM, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/005093
Kind Code:
A1
Abstract:
To support the sharing of communication resources among a plurality of secondary communication services. The disclosed communication control device is for controlling communications carried out by a plurality of secondary-use nodes that each provide secondary communication services by using a portion of a frequency band assigned to a primary communication service, the communication control device including: a communication section that receives, from each secondary-use node, access scheme information that indicates wireless access schemes that can be used by each said secondary-use node; a storage section that stores the access scheme information received by the communication section; and a control section that, in cases where the service area of a first secondary communication service includes at least a portion of the service area of a second secondary communication service, determines whether or not at least a portion of communication resources can be shared between the first secondary communication service and the second secondary communication service on the basis of the wireless access schemes of the first and second secondary communication services as indicated by the access scheme information.
