Abstract The present invention relates to a base station(1, 1') and a method for protecting a predetermined area from disturbing usage of mobile terminals(7) whose operation mode of can be changed by mode change information 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(1, 1') according to the present invention thereby comprises generating means(2, 2'), and transmitting means(3, 3') for transmitting the generated mode change information within the predetermined area by means of a paging message. The use of the paging message thereby provides a simple and effective way to transmit the mode change information.
