Communication control method and communication system for starting secondary usage of an assigned spectrum

摘要

There is provided a communication control method comprising the steps of: providing an instruction for determining availability of usage of a second communication service using a part or whole of a spectrum assigned to a first communication service from a first communication device to a second communication device; providing an instruction for sensing a communication environment from the second communication device to a communication device located nearby; transmitting sensed data obtained by sensing a communication environment from a third communication device located near the second communication device to the second communication device; determining availability of usage of the second communication service based on the sensed data by the second communication device; transmitting a determination result on availability of usage of the second communication service from the second communication device to the first communication device; and permitting usage of the second communication service in accordance with the determination result received from the second communication device by the first communication device.

1. A communication control method comprising the steps of:
providing an instruction for determining availability of usage of a second communication service using a part or whole of a spectrum assigned to a first communication service from a first communication device to a second communication device; providing an instruction, for sensing a communication environment, from the second communication device to a third communication device located nearby the second communication device, wherein the third communication device is separate and located apart from the second communication device; transmitting sensed data, obtained by sensing the communication environment, from the third communication device to the second communication device; determining availability of usage of the second communication service based on the sensed data by the second communication device; transmitting a determination result on availability of usage of the second communication service from the second communication device to the first communication device; and permitting usage of the second communication service in accordance with the determination result received from the second communication device by the first communication device.
