SYSTEM AND METHOD FOR ESTABLISHING SECONDARY CHANNEL

PROBLEM TO BE SOLVED: To provide a method for performing communications by utilizing a channel of low band width like a telephone to automatically establish a secondary channel. SOLUTION: While utilizing a primary channel on network medium, the secondary communication channel is established between at least two computer systems 140, 142. The first computer system including a first telephone set and the second computer system including a second telephone set are connected. While two telephone sets 110 and 112 are under mutual communications on the primary channel and when a communication channel is established between the computer systems and between their telephone sets, the first computer system transmits its location information to the second computer system via the primary channel. On the secondary channel, the connection is then established between the second computer system and the first computer system. COPYRIGHT: (C)2005,JPO&NCIPI
