<p><P>PROBLEM TO BE SOLVED: To provide a real time communication system that improves flexibility by saving a band. <P>SOLUTION: In this real time communication system in which a second communication terminal instructs holding to temporarily stop real time communication while a call is established between a first communication terminal and the second communication terminal to perform real time communication, and a prescribed hold signal is outputted instead of a signal by real time communication through a user interface of the first communication terminal that is held until the holding is released, a hold signal source communication terminal other than the second communication terminal, or the first communication terminal is provided with a hold instruction detecting part for detecting that the second communication terminal outputs a holding instruction and a hold signal supplying part for supplying a hold signal when the hold instruction detecting part that detects that the second communication terminal outputs the holding instruction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
