Mobile communication system, radio base station, scheduling apparatus, scheduling method employed in the same, and program thereof

摘要

The invention provides a radio base station which can achieve high throughput while attaining the target quality for each mobile station and fairly assigning a transmission opportunity. In the radio base station, when a mobile station selection unit is notified at a fixed period of time by a data flow control unit with respect to a mobile station which has data to be transmitted, the unit selects a plurality of mobile stations which don't achieve the service quality. The plurality of mobile stations selected by the mobile station selection unit are input into a PF scheduler. From these mobile stations, a mobile station to which a transmission opportunity is assigned, is determined. A mobile station notification unit assigns a transmission opportunity to the mobile station determined by the PF scheduler. Upon completion of the transmission opportunity assignment, the mobile station notification unit notifies the data flow control unit of the mobile stations to which a transmission opportunity has been assigned.
