Abstract
In a communication channel set up method, the utilization state of a prescribed frequency in the first frequency band that causes interferences to the first communication system when the communication channel of a particular frequency in the second frequency band is used at the second communication system is detected, and if the prescribed frequency in the first frequency band is currently used, the communication channel other than that of the particular frequency is allocated to the second communication system.
Claims8
A communication channel set up method for setting up a communication channel to be used by a second radio communication system that can use a second frequency band close to a first frequency band that can be used by a first radio communication system, comprising:
- detecting a utilization state of a prescribed frequency in the first frequency band that can cause interferences to the first radio communication system when a communication channel of a particular frequency in the second frequency band is used by the second radio communication system;
- and
- allocating a communication channel other than that of the particular frequency to the second radio communication system when the prescribed frequency in the first frequency band is currently used by the first radio communication system.
A communication control device for controlling a communication channel to be used by a second radio communication system that can use a second frequency band close to a first frequency band that can be used by a first radio communication system, comprising:
- a detection unit configured to detect a utilization state of a prescribed frequency in the first frequency band that can cause interferences to the first radio communication system when a communication channel of a particular frequency in the second frequency band is used by the second radio communication system;
- and
- an allocation unit configured to allocate a communication channel other than that of the particular frequency to the second radio communication system when the prescribed frequency in the first frequency band is currently used by the first radio communication system.
