摘要 |
A probe transmitting section (216) in a packet receiving terminal (210) sends a probe packet to a second radio channel (320) at fixed intervals. A probe analyzing section (117) in a packet sending terminal (110) 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 (118) predicts that a data packet transmitted during the period of the detected burst loss among data packets sent from a priority processing transmission buffer (115) to a first radio channel (310) is a data packet lost on a receiving side, reads the data packet from a retransmission buffer (114), and then sends the data packet to the priority processing transmission buffer (115). A real-time property can be ensured while a packet loss is overcome in a radio environment.
