SUMMARY OF THE INVENTION The present invention provides a method for setting a clock device in a phone with a portable device (mobile terminal) caused by a power failure or other insufficient charge. When the call button 21a attached to the terminal is pressed, the second MCU 22 determines whether the call button 21a is pressed by the input signal (S1a), and when the call button 21a is pressed. The second RF module 24 transmits it to the fixing device. Subsequently, when the user presses the call end button 21b after the call for a predetermined time, the second MCU 22 determines whether the call end button 21b is pressed by the input signal (S2a). When the end button 21b is pressed, it is transmitted to the fixing device through the second RF module 24.

In addition, the fixed device inputs a call termination signal transmitted from the second RF module 24 through the first RF module 20, and outputs it to the first MCU 18 after demodulation. The first MCU 18 detects whether the call end signal is received from the portable device (S1b). If the call end signal is not received, the first MCU 18 continuously performs the control role of the fixed device itself. Is received, it outputs the current time data of a predetermined time point that is continuously counting in the base station based on this. Accordingly, the first RF module 20 outputs the current time data inputted from the first MCU 18. The current time is modulated and transmitted to the portable device (S2b).

In addition, the portable device receives the current time data of a predetermined time point transmitted from the first RF module 20 of the fixed device, and the second RF module 24 demodulates the data to the second MCU 22. The second MCU 22 determines whether the predetermined time data is input from the second RF module 24 (S3a), and when the input is made, the second LCD 22 displays the time at the present time. By displaying through (23), it is possible to automatically set the current time with the input of a call attempt and end button, that is, a call.

On the other hand, the present invention can be modified in various ways without departing from the technical spirit of the present invention.

As described above, the apparatus and method for automatically adjusting the clock of the wireless phone according to the present invention, when the user presses a button of call initiation and end through the mobile terminal of the telephone, recognizes that the signal is confirmed through the MCU of the fixed terminal. In addition to the signal, the current time data is transmitted to the mobile terminal, and the MCU of the mobile terminal displays the received current time data on the LCD, so that the time of the mobile terminal in the case of a power failure or other charging is not available. It is possible to automatically set the current time with only one phone call of an unspecified user without the need for a new setting, thereby increasing convenience in use.
