Patent ID: 6993329

Claim:
An apparatus for automatically switching a communication/communication suppression mode of a wireless communication terminal, comprising: a communication a suppression control signal reception means for receiving a communication suppression control signal radiated from an external communication suppression control signal generation means that is set up inside an entrance of a communication restriction area, generates and radiates the communication suppression control signal which is a feeble radio signal; a communication suppression release control signal reception means for receiving a communication suppression release control signal from an external communication suppression release control signal generation means that is set up outside an exit of the communication restriction area, generates and radiates the communication suppression release control signal which is a feeble radio signal; a central processing means for receiving a communication suppression control signal from the communication suppression control signal reception means and notifying a base station of the wireless communication terminal being in the communication restriction area, and for controlling the wireless communication terminal to operate normally in response to the communication suppression release control signal from the communication suppression release control signal reception means; and a transmit path on/off switching means for blocking a radio frequency (RF) signal radiated from an antenna of the terminal while keeping the wireless communication terminal power-on by receiving the communication suppression control signal from the central processing means and turning off the transmit path of the wireless communication terminal, and for switching it into a normal communication mode by receiving the communication suppression release control signal from the central processing means and turning on the transmit path of the wireless communication terminal.
