ABSTRACT:
An interactive call is set up by a method including the steps of: emitting a message from the terminal to the connection network defining the resources required for all of the connections and for all the periods of the call, and emitting a message from the connection network to the terminal indicating that the network possesses such resources for at least one call. During each interactive call, prior to each new period requiring different resources, and for each connection of the call, the method further includes the steps of: emitting a message from the terminal to the connection network indicating each connection that is going to be necessary during the new period and indicating the resources that will be required for the connection, emitting a message from the connection network to the terminal confirming that the resources have been reserved by the network, and storing in the terminal data to be transmitted over the connection network until the terminal receives the message. Thus, at each instant, the capacity of the resources reserved by the network for an interactive call is accurately matched to the binary bit rate to be transmitted during the call. The method is particularly applicable to telecommunications networks using the ATM technique.
