Wireless communication apparatus and band assigning method
First Claim
1. A base station device, comprising:
- a transmission and reception unit to transmit and receive user data to and from a mobile terminal;
a no-communication time count unit to count no-communication time in which the transmission and the reception of the user data have been interrupted in the mobile terminal;
an assignment unit to release a frequency band assigned to the mobile terminal when the no-communication time becomes longer than a duration in which the assignment of the frequency band to the mobile terminal is continued; and
a duration adjustment unit to adjust the duration when the no-communication time is longer than the duration, and the no-communication time is shorter than a sum of the duration and a monitor time in which it is monitored whether or not the no-communication time is continued after releasing the frequency band.

Abstract
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.

7. A communication device, comprising:
-
a transmission and reception unit to transmit and receive user data to a base station to which a mobile terminal is connected so as to relay a communication between the mobile terminal and a communication partner device; a no-communication time count unit to count a no-communication time in which the transmission and reception of the user data have been interrupted; and a duration adjustment unit to acquire a duration in which the base station continues an assignment of a frequency band to the mobile terminal, and to adjust the duration when the no-communication time is longer than the duration, and the no-communication time is shorter than a sum of the duration and a monitor time in which it is monitored whether or not the no-communication time is continued after releasing the frequency band, wherein the transmission and reception unit transmits the adjusted duration to the base station.

8. A method of assigning a frequency band, comprising:
-
counting no-communication time in which the transmission and the reception of the user data have been interrupted in a mobile terminal; releasing a frequency band assigned to the mobile terminal when the no-communication time becomes longer than a predetermined duration; and adjusting the duration when the no-communication time is longer than the duration, and the no-communication time is shorter than a sum of the duration and a monitor time in which it is monitored whether or not the no-communication time is continued after releasing the frequency band. - View Dependent Claims (9)
