ABSTRACT:
A communication channel establishing method by which point-to-multipoint or multipoint-to-point connections by a communication network which includes exchanges (switches) can be established at a high speed. When a connection establishment request designating called users 11, 12 and 13 is received from calling user 10, switch 100 retrieves routes to the individual called users and selects switch 102 in the next stage and sends out a connection establishment request to switch 102 designating called users 11, 12 and 13. Switch 102 further retrieves routes to the individual called users and selects switch 103 for called users 11 and 12, but selects switch 104 for called user 13. Then, switch 102 sends out connection establishment requests to switches 103 and 104 individually designating the relevant called users. Any connection establishment request received from a switch of the preceding stage is successively repeated to a selected switch in the next stage until each called user is reached.
