In addition, the old area code and the changed new area code data are read from the memory unit 102 to convert the old area code into a new area code. The memory unit 102 connected to the controller 100 includes a read access memory (ROM), a flash memory, a random access memory (RAM), and the like. The ROM stores a program for processing and controlling the controller 100, a program for the controller 100 to perform an automatic conversion function, and various reference data. The RAM also provides a working memory of the controller 100. The flash memory provides an area for storing various updatable storage data. In addition, the key pad 104 includes various keys including numeric keys to provide the controller 100 with a key input input by the user. The display unit 106 typically includes a liquid crystal display (LCD) to display various types of information as images under the control of the controller 100. The RF module 110 transmits and receives an RF signal to and from the base station through the antenna 108. The received RF signal is converted into an intermediate frequency (IF) signal and output to the baseband processor 112, and the baseband processor 112 IF signal inputted from) is converted into RF signal and transmitted.

The baseband processor 112 is a baseband analog ASIC (BBA) that provides an interface between the controller 100 and the RF module 110. The baseband processor 112 converts a baseband digital signal applied from the controller 100 into an analog IF signal. The conversion is applied to the RF module 110, and the analog IF signal applied from the RF module 110 is converted into a digital signal of the baseband and applied to the control unit 100. In addition, the codec 114 connected to the control unit 100 is connected to the microphone 118 and the speaker 120 through the amplifying unit 116, and the PCM (Pulse Code Modulation) encoding of the voice signal input from the microphone 118 ( After encoding, the voice data is output to the controller 100, and the PCM decoding of the voice data input from the controller 100 is performed to output the voice signal to the speaker 120 through the amplifier 118. The amplifier 116 amplifies the voice signal input from the microphone 118 or the voice signal output to the speaker 120. The volume of the speaker 120 and the gain of the microphone 118 are controlled by the control unit 100. Adjust accordingly. The ringer 122 generates a ring tone under the control of the controller 100, and the vibrator 124 generates vibration under the control of the controller 100.
