1. A method for initiating a communication connection between a calling party and a called party within a telecommunication network system comprising multiple interconnected networks, said method comprising the steps of:

  • initiating, in a circuit-switched network of the telecommunication network system, a circuit-switched connection between the calling party and the called party, and initiating, in a packet-switched network of the telecommunication network system, a packet-switched connection between the calling party and the called party;

    alerting a circuit-switched part of a terminal of said called party with a first alert signal about the initiation of said circuit-switched connection;

    alerting a packet-switched part of the terminal of said called party with a second alert signal about the initiation of said packet-switched connection;

    after alerting said called party with said first and second alert signals, receiving a circuit-switched response at the circuit-switched network and a packet-switched response at the packet-switched network, both the circuit-switched and packet-switched responses being triggered by a single response received at the terminal from the called party at one of the circuit-switched part and the packet-switched part of the terminal in response to said first and second alert signals; and

    based on the single response, indicating to the other one of the circuit-switched part and the packet-switched part of the terminal whether the terminal accepts establishment of a corresponding one of the circuit-switched or packet-switched connections,wherein the circuit-switched and packet-switched responses indicate to the respective circuit-switched and packet-switched networks;

    whether the circuit-switched part of the terminal accepts establishment of said circuit-switched connection, andwhether the packet-switched part of the terminal accepts establishment of said packet-switched connection.
