Method for transmission of data including signaling the necessity of a second communications path to a network control system

A method of transmitting data, which comprises:

• establishing a first communications path via a first communications network between a first communications subscriber connected to a first network access point, and a second communications subscriber connected to a second network access point;
• signaling a need for a second communications path to a network control system with one of the network subscribers, responsively requesting a switching network element in a second communications network to establish the second communications path between the first communications subscriber and the second communications subscriber with the network control system, and establishing the second communications path;
• upon determining a need for the second communications path:
• allocating an access code with the network control system to the network access point of the second communications subscriber or to the second communications subscriber itself;
• informing the first communications subscriber or the network access point connected to the first communications subscriber of the access code;
• and
• setting up a connection via the access code with the first communications subscriber or the network access point of the first communications subscriber;
• and
• transmitting further data via the second communications path.
