Abstract:
A wireless communication system includes an RNC and a BTS which communicates with the RNC. A congestion-notification transmitting unit of the BTS notifies the RNC of occurrence of congestion in a sector in which a mobile station is located. The RNC includes a congestion-notification receiving unit, a retransmission-ratio monitoring unit, and a transmission-rate control unit. The congestion-notification receiving unit detects the congestion occurrence by the notification from the BTS. The retransmission-ratio monitoring unit monitors a ratio of retransmission of a packet to the mobile station. The transmission-rate control unit performs control of changing a transmission rate of a packet to the mobile station according to the retransmission ratio when the congestion occurrence has been detected by the congestion-notification receiving unit.
