1. A method for controlling a signalling procedure in a communication terminal equipment, a call setup or call clearing between the communication terminal equipment and a communication system connected thereto, as well as, performance feature controls within a framework of the call setup and call clearing and during a communication phase being controlled by the signalling procedure realized in program-oriented terms and controlled by key actuations, comprising the steps of:

  • providing signalling sub-procedures definable by different procedure control information, said signalling sub-procedures forming the signalling procedure;

    forming first procedure control information that defines a signalling sub-procedure after every activation of the communication terminal equipment and before every branching of the signalling procedure into a plurality of signalling sub-procedures and communicating said first procedure control information to a display device for displaying at least the first procedure control information;

    activating a sequence key in the communication terminal equipment, and in response thereto forming further procedure control information defining a further signalling sub-procedure and communicating the further procedure control information to the display device; and

    activating an actuation key in the communication terminal equipment, and in response thereto selecting and executing a signalling sub-procedure respectively defined by procedure control information most recently supplied to the display device.
