Method to conference call offering in asynchronous transfer mode network

摘要

PURPOSE: A method of supplying a conference call in an ATM network is provided to mask a channel connected to a line requesting a conference call in the ATM network, and to use a method of broadcasting conference call data, thereby enabling the conference call in the ATM network. CONSTITUTION: A subscriber '1' requests a conference call(S101), and inputs telephone numbers of subscribers '2' and '3' for the conference call(S102). An ATM network calls telephones '2' and '3' to connect the telephones(S103), and retrieves a channel connected to the telephones '2' and '3'. The ATM network masks each channel for the conference call(S104). When the channel masking is completed, the conference call is executed(S105). Data on the conference call is broadcasted to a channel presented by a masked bit(S106). When a conference ends(S107), a masked table is re-masked.
