METHOD FOR PROTECTING A LIMITED LOCAL AREA AGAINST ELECTROMAGNETIC RADIATION EMITTED BY MOBILE RADIOTELEPHONE TERMINALS, AND CORRESPONDING RADIO STATION

摘要

In an area to be monitored, first signaling information is deliberately emitted to synthetically create conditions which force the mobile radio terminals that are to be detected to transmit second signaling information as a reaction. The second signaling information is then processed in order to detect mobile radio terminals which are not switched off.
