In addition, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It will be obvious to those skilled in the art. In describing the present invention, when it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. The terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or a chip designer, and the definitions should be made based on the contents throughout the present specification.

1 is a block diagram showing a fixing device of a radiotelephone according to the present invention.

The stationary device of the radiotelephone uses commercial power as a driving power source.

A central processing unit 20 for controlling the overall operation of the fixing apparatus by a predetermined program, a key input unit 21 having a light key, a light off key, a numeric key and various keys, and wirelessly controlled by the central processing unit 20 A display unit 22 having a device for displaying various status information and various data of a telephone and a light emitting diode, a memory 25 for storing a light implementing program and a control program, and a memory 25 for temporarily storing various data generated during program execution, An RF module 23 performing wireless communication with a device (not shown), and connected between the CPU 20 and the RF module 23, for transmitting data output from the CPU 20 to the portable device. Modem 24 which modulates and demodulates the modulated signal received from the portable device to the central processing unit 20 and is connected to a telephone line. An interface 30 for interfacing with the exchanger, a communication unit 28 connected to the interface 30 for processing and switching various signals and voice signals under the control of the central processing unit 20, and the central processing unit 20 and the communication unit 28. An audio circuit 26 for transmitting and receiving a voice signal with a telephone line and for outputting music to a speaker SP for a predetermined time under the control of the central processing unit 20 when the electric light key is input to the key input unit 21; And a pulse / DTMF generator 27 connected between the central processing unit 20 and the communication unit 28 to generate a pulse or DTMF signal in response to an input dialing key and to output the pulse or DTMF signal to the communication unit 28.

2 shows a method of implementing a light circuit when a commercial power supply is interrupted at night in a fixing device of a radiotelephone having the above configuration.

Referring to FIG. 2, the central processing unit 20 checks whether the commercial power supply is interrupted in step 202. In the case of power failure in step 202, the process proceeds to step 204 to emit light of the light emitting diode of the display unit 22 for a predetermined time and simultaneously transmits music through the audio circuit 26 and the speaker SP. Thereafter, the CPU 20 checks whether an electric light key is input through the key input unit 21. If the light key is input in step 206, the central processing unit 20 continues to emit light of the light emitting diode and transitions to step 210 to check the light off key input. In step 210, when the light-off key is input, the CPU 20 stops emitting light of the LED. On the other hand, in step 202, if the commercial power is not powered off, the process shifts to step 216 to wait for the general telephone function. If there is no input of the light key in step 206, the CPU 20 checks whether the commercial power supply is out of power by going to step 214, and if the power failure occurs, the process proceeds to step 206 and repeats the test of the input of the light key. If the commercial power supply is not interrupted in step 214, the process shifts to step 216 to wait for the telephone function.

The controller 111 controls the overall operation of the mobile radio telephone. The first memory 112 stores a program and initial service data. The first memory 112 may be configured as an EEPROM. The second memory 113 temporarily stores data generated during operation of the mobile radio telephone. The second memory 113 may be configured as a RAM. The key input unit 114 includes a light key and a light off key. The logic unit 115 transmits / receives data for controlling the operation of the mobile radio telephone with the control unit 111. The logic unit 115 outputs control data for controlling the operation of each unit of the mobile radio telephone. The data processor 116 performs data communication with the controller 111. The data processor 116 processes the received data RXD output from the RF receiver 120 and applies the signal to the controller 111. The data processor 116 processes the transmitted data RXD output from the controller 111 and outputs the signal to the RF transmitter 121. The data processor 116 may use a digital signal processor.

The duplexer 122 is connected to an antenna to separate a transmission RF signal and a reception RF signal. The RF receiver 120 is connected to the duplexer 122 and outputs the received RF signal by frequency conversion and demodulation. The received audio signal RXA output from the RF receiver 120 is output to the audio receiver 117, and the received data RXD is output to the data processor 116. The audio receiver 117 inputs an audio signal output from the RF receiver 117 to reproduce the audio signal. The audio transmitter 118 inputs and processes an audio signal. The RF transmitter 121 inputs the transmission audio signal TXA output from the audio transmitter 118 and the transmission data TXD output from the data processor 116, modulates the transmission data TXD, and outputs the same to the duplexer 122. The frequency synthesizer 119 generates a frequency synthesized signal for allocating a reception channel of the RF receiver 120 and a transmission channel of the RF transmitter 121 by control data of the logic unit 115. The display unit 124 includes a light emitting diode that generates light in response to input of the light key and the light key, and turns off the generation of light, and a device for displaying various data generated by the control unit 111.

In the mobile radiotelephone having the above-described configuration, a light implementing method at night is shown in FIG.

Referring to FIG. 4, the control unit 111 checks whether there is a predetermined key input in step 402, and if there is a key input, the control unit 111 transitions to step 404 and checks the light key input. If there is an input of the light key in step 404, the control unit 111 emits a light emitting diode and proceeds to step 408 to check the light off key input. If the input of the light off key is checked in step 408, the process proceeds to step 410 to turn off the light emitting of the light emitting diodes. If there is no key input in step 402, the process proceeds to step 412 to perform a telephone function. If there is no light key input in step 404, the process proceeds to step 414 to perform a function corresponding to the key input.
