The RF transmitter / receiver 202 to the display unit 210 correspond to the circuit configuration of the mobile phone 1000, and the antenna coil 213 to rectifier 219 correspond to the smart card circuit block 3000. In particular, the modulator / demodulator 216, the smart card controller 217, the memory 218, and the rectifier 219 of the smart card circuit block 3000 are configured as a smart card integrated circuit 2000.

First, the general mobile phone operation is described as follows.

The key input unit 207 has a function key and various input keys for controlling the mobile phone. When the user inputs the power key, the control unit 206 decodes the input power key to operate the mobile phone power switching unit 211. The control determines the power supply of the battery 212 to the mobile phone circuit (1000).

When a signal transmitted from the base station is received through the antenna 201, the RF transmitter / receiver 202 removes the carrier signal from the input signal, demodulates it, and inputs the signal to the signal processor 203. The signal processor 203 then detects the signal received by the built-in signal detection circuit and transmits information about the detected signal to the controller 206. Then, the controller 206 controls the ring signal generator 209 to output a ring signal indicating that the call request signal is received to the speaker 204.
