METHOD AND SYSTEM FOR USING FUNCTION KEYS FOR DISPLAYING THE NUMBER AND CALLING OF EVENTS

摘要

The invention relates to a method for operating a terminal device (1) that can be used in a telecommunication network, preferably a mobile radio network, and that has a display device (2, 3) for optically and/or acoustically displaying information and at least one input device (4, 5, 6) for acquiring information. The invention is characterized in that the number of information available for a more extensive use is recorded and is displayed on the display device (2, 3) of the terminal device (1). By actuating the input device (4, 5, 6, 10) of the terminal device (1), a more extensive use of information is made possible. In order to simplify the use or manageability of the terminal device with a view to a more extensive use of available information, especially for seniors and/or inexperienced users, or render it less complicated, the number is decremented or incremented and displayed correspondingly on the input device (2, 3) of the terminal device (1). The invention further relates to a terminal device (1) for use in a telecommunication network, preferably a mobile radio network, comprising a display (2, 3) for optically and/or acoustically displaying information and at least one input device (4, 5, 6, 10) for acquiring information. The number of information available for a more extensive use can be displayed on the display device (2, 3) and at least a more extensive use of information is made possible by actuating the input device (4, 5, 6, 10), said terminal device comprising at least one counting device for recording the number of information available for a more extensive use.
