A base station device includes a transmission and reception unit, a no-communication time count unit, an assignment unit, and a duration adjustment unit. The transmission and reception unit transmits and receives user data to and from a mobile terminal. The no-communication time count unit counts the no-communication time in which the transmission and reception of the user data has been interrupted in the mobile terminal. When the no-communication time becomes longer than the duration in which the assignment of the frequency band to the mobile terminal is continued, the assignment unit releases the frequency band assigned to the mobile terminal. When the no-communication time is longer than the duration, and the no-communication time is shorter than the sum of the duration and the monitor time in which it is monitored whether the no-communication time continues after the release of the frequency band, the duration adjustment unit adjusts the duration. |
