摘要： An apparatus and method for automatically switching communication/communication suppression mode of a wireless communication terminal is disclosed. The apparatus for automatically switching communication/communication suppression mode of the wireless communication terminal includes: a communication suppression control signal receipt unit for receiving a communication suppression control signal radiated from a control signal generation unit located in a communication suppression area; a communication suppression release control signal receipt unit for receiving a communication suppression release control signal radiated from a communication suppression release control signal generation unit located in an outside of the communication suppression area; and a switching unit for switching a transmission path of the wireless communication terminal off based on the communication suppression control signal and switching the transmission path of the wireless communication terminal on in order to return to the communication mode based on the communication suppression release control signal, so that the wireless communication terminal keeps its power on and radio frequency power is not radiated from the wireless communication terminal.
