PURPOSE: A method for supplying a multi-point conference using a push method is provided to start a conference promptly without approvals of expectant conference participators when a conference opening request message of a conference manager is transmitted by sensing state variations of the conference participators periodically. CONSTITUTION: A conference supply unit receives log-in requests of terminals of many expectant conference participators as to a conference system(S201), authenticates the conference participators(S203), and receives "compulsory conference approval" request which informs that the conference participators participate in the conference without approvals with respect to a conference opening request of a conference manager from the terminals(S205). An expectant conference participators managing unit senses and manages states of the terminals(S207). If an expectant conference participator transmits a conference opening request, the request is received(S209), and the expectant conference participator becomes a conference manager. The expectant conference participators managing unit transmits a conference opening request message to other terminals, through a push server(S211). At the same time, a conference program is transmitted to other terminals, respectively(S213). |
