Abstract
A probe transmitting section () in a packet receiving terminal () sends a probe packet to a second radio channel () at fixed intervals. A probe analyzing section () in a packet sending terminal () detects a burst loss on the basis of a state of reception of the probe packet. When a burst loss detection is detected, a predictive retransmission control section () predicts that a data packet transmitted during the period of the detected burst loss among data packets sent from a priority processing transmission buffer () to a first radio channel () is a data packet lost on a receiving side, reads the data packet from a retransmission buffer (), and then sends the data packet to the priority processing transmission buffer (). A real-time property can be ensured while a packet loss is overcome in a radio environment.
