Abstract
The present invention relates to the rate control system of a TCP layer in communications conducted between terminals 1 and 3 via a base station 2 using a wireless link. An object of the present invention is to avoid the fruitless reduction of throughput in communications conducted via a wireless link. If the discard of a packet transmitted from the base station 2 to the terminal 3 via a wireless link is detected when the packet is transmitted from the terminal 1 to the terminal 3, the base station or terminal 3 is provided with means for notifying the terminal 1 of a wireless packet discard using a TCP layer. The terminal 1 is configured in such a way that if the wireless packet discard notification is received, a TCP layer control unit 10 does not exercise slow-start control at the time of re-transmission and re-transmits the discarded packet at a rate adopted before the reception of the notification.
