DATA COMMUNICATION SYSTEM, APPARATUS AND METHOD FOR TRANSMISSION OF DATA, AND APPARATUS AND METHOD FOR RECEPTION OF DATA

摘要

PROBLEM TO BE SOLVED: To ensure a real time getting over a packet loss in a wireless environment.

SOLUTION: The probe transmission unit 216 of a packet receiving terminal 210 sends out a probe packet to a second radio channel 320 at a constant interval. The probe analysis unit 117 of a packet sending terminal 110 detects a burst loss on the basis of the receiving context of the probe packets. A prediction retransmission control unit 118 predicts that the data packets, which are transmitted in the detected burst loss period, out of data packets sent out from a transmission buffer 115 to a first radio channel 310 are the data packets lost at a receiving side when a burst loss is detected, and the above data packets are read out from a resending buffer 114 and sent out to the transmission buffer 115.
