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.

DETAILED DESCRIPTION What is claimed is: 1.
A base station for protecting a predetermined area from disturbing usage of mobile terminals of a wireless communications system, comprising: a generator for generating mode change information for changing an operation mode of said mobile terminals to prevent said mobile terminals from operating in a disturbing mode, and for generating identifying information representing at least one group of mobile terminals that receive said mode change information but are excluded from changing their operation mode; and a transmitter coupled to the generator for transmitting said generated mode change information and said identifying information within said predetermined area by means of a message on a predetermined channel of said wireless telecommunication system.
2.
The base station of claim 1, wherein said mode change information replaces at least a portion of message in said predetermined channel.
3.
The base station of claim 1, wherein said mode change information is transmitted in addition to said message in said predetermined channel.
4.
The base station of claim 1, wherein said mode change information contains individual mode change information for changing the mode of selected mobile terminals individually addressed by said individual mode change information.
5.
The base station of claim 1, wherein said transmitter regularly transmits said mode change information.
6.
The base station of claim 1, wherein said mode change information is operable to deactivate at least a high frequency portion of the mobile terminal that receives said mode change information.
7.
The base station of claim 1, wherein said mode change information is operable to turn off audible signal generators of the mobile terminal that receives said mode change information.
8.
The base station of claim 1, wherein said mode change information includes timing information to establish a time duration during which the operating mode of the mobile terminal that receives said mode change information remains changed
