A communication resource management device changes the transfer rate of a first control channel related to a first mobile terminal according to a communication condition. The device determines whether there is a frequency band for which it is not determined whether the frequency band is to be used in a predetermined time period based on a current transfer rate of a second control channel related to a second mobile terminal and an amount of data to be transmitted in the second control channel; and allocates, to the first mobile terminal, at least a part of the frequency band for the second control channel with respect to the second mobile terminal in a predetermined period of time. The device changes the transfer rate in the first control channel while maintaining the total frequency band for plural control channels related to plural mobile terminals at a constant value.
