PURPOSE: A hierarchical multilateral communication method and system are provided to minimize average media delay time by logically constructing a connection path. CONSTITUTION: A reception terminal individually obtains a connection margin and a partial turnaround time from one or more other terminals(430). The reception terminal computes an average media delay value for the selected candidate terminal(437). The reception terminal selects a candidate terminal including a minimum average media delay value as a connection terminal(440). When the selected connection terminal is a terminal which receives the communication connection request message of a new terminal, the reception terminal sets a logical communication path with the new terminal(455,465). [Reference numerals] (410) Receiving a communication connection request message; (415) Including introduction information?; (420) Transmitting a permission message as a response message; (425) Reconstituting a logical connection path according to the communication participation of a new participate terminal; (430) Individually obtaining a connection margin and a partial turnaround time from terminals participating in communication; (435) Selecting candidate terminals with a connection margin higher than a reference value; (437) Computing an average media delay value for the selected candidate terminals using the absorption and partial turnaround time between the terminals; (440) Selecting a candidate terminal with the minimum average media delay value as a connection terminal; (445) Selected terminal exists?; (450) Transmitting a refusal message as a response message; (455) Selected connection terminal = Receiving terminal?; (460) Transmitting a permission message as a response message; (465) Reconstituting a logical connection path according to the communication participation of a new participate terminal; (470) Transmitting an introduction message as a response message; (AA,DD,FF) Yes; (BB,CC,EE) No |
