Abstract

A predetermined area is protected from the disturbing usage of mobile terminals (e.g. cell phones) of a wireless communication system. Mode change information is sent over certain predetermined channels of a telecommunication system to change the operating mode (e.g. to deactivate) of the mobile terminal. This mode change information contains information, such as, the duration of the mode change, a reason for the mode change and information on groups of mobile terminals that will be exempted from the mode change. Additionally, the mobile terminal transmits an alarm signal to the user if the user is approaching a predetermined protected area.
