Communication control method and communication control system
First Claim
1. A communication control method for conducting communication between a transmission side radio station and a reception side radio station in a radio network in which a plurality of the radio stations are deployed, comprising the steps of:
- (1) transmitting a notification signal that notifies information of a frequency of a radio link being used at each radio station;
(2) measuring a reception power level of a radio signal received and detecting a frequency of each radio signal at the reception side radio station;
(3) transmitting the reception power level and the detected frequency of the radio signal from the reception side radio station to the transmission side radio station;
(4) measuring a reception power level of each of the notification signals and detecting the frequency of the radio link being used at each of the radio stations, which is notified by the notification signal, at the transmission side radio station;
(5) determining an assignable frequency band to be used between the transmission side radio station and the reception side radio station at the transmission side radio station based on the reception power level and the detected frequency of the radio signal, the reception power level of the notification signal and information contained in the notification signal,(6) notifying information of an assigned frequency band from the transmission side radio station to the reception side radio station based on a result of the determination; and
(7) transmitting a new notification signal correlating with the assigned frequency band at the reception side radio station according to the information of the assigned frequency band.

Abstract
A reception side radio station has a notification signal generator 108 which transmits a notification signal for notifying information of a frequency of a radio link being used at the radio station, and a transmitter 111 which transmits information indicating a reception power level and its frequency as radio signal data. On the other hand, a transmission side radio station has a notification signal measurer 106 which measures a reception power level of the notification signal and detects the frequency notified by the signal, and a frequency band controller 109 which determines an assignable frequency band for a radio link between the transmission side radio station and the reception side radio station based on the radio signal data and the notification signal.
