Abstract
There is provided admission control in view of wireless resources. A base stationobtains a down wireless resource available rate (available rate of slot allocation) based on a down QoS requested bandwidth Brequested by a terminal i during QoS communication and a data rate Rwhich the terminal can receive. A down wireless resource usage rate necessary to ensure the requested bandwidth B is obtained by dividing a down QoS requested bandwidth B requested by the terminal trying to perform QoS communication by the data rate R which the terminal can receive. The base stationobtains an up wireless resource available rate based on ROT of an up channel and a threshold value Tindicating an allowable upper limit of the ROT. Besides, an up wireless resource usage rate necessary to ensure an up requested bandwidth requested by the terminal is obtained. The QoS communication is performed on the terminal in which the up and down wireless resource available rates are respectively equal to or more than the up and down wireless resource usage rates.
