<P>PROBLEM TO BE SOLVED: To prevent or reduce an influence by deteriorated communication data quality because of a packet loss in packet communication. <P>SOLUTION: A plurality of PAD 112a, 112b and 212a, 212b are provided on a first terminal 1 and a second terminal 2, respectively. Packet communication is performed using one of the plurality of PADs. On detection of a packet loss in a reception data of the packet communication deteriorated to a preset threshold, transmission of a data common to the one PAD is requested to the first terminal using another PAD. The packet loss rate of the reception data by the one PAD is compared in magnitude with the packet loss rate of the reception data by the other PAD, and packet communication is continued by the adoption of a system having a smaller packet loss rate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
