Abstract The present invention relates to a base station and a method for protecting a predetermined area from disturbing usage of mobile terminals of a wireless telecommunication system. Further, the present invention relates to a mobile terminal the operation mode of which can be changed by mode change information received from a base station to protect a predetermined area. A predetermined area might be an area, in which at least a high frequency part of the mobile terminals should be switched off automatically to avoid interference with electronic or electric devices. In other areas, it is sufficient to reduce the volume of acoustic signals to be output so that other people in the area are not disturbed. The base station for protecting the predetermined area according to the present invention thereby comprises receiving means for receiving a registration or location update request message from a mobile terminal of said wireless telecommunication system, generating means for generating mode change information for changing an operation mode of the mobile terminals to protect the predetermined area, and transmitting means for transmitting the generated mode change information within the predetermined area. The use of the location updating answer message thereby provides a simple and effective way to transmit the mode change information according to the present invention.
