Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

First, in step 400 of FIG. 4, the control unit 111 of FIG. 1 determines whether power is supplied to the portable telephone and is in an operating state. If the operation state in step 400, the process proceeds to step 410 and checks whether the jack of the earphone is inserted into the plug shown in (3b) of FIG. This check is made if the jack of the earphone is connected to the insertion detecting terminal 50 of the plug. As a result of the check, when the jack of the earphone is inserted into the insertion detecting terminal 50, the insertion detecting terminal 50 generates an insertion signal and applies it to the controller 111. The controller 111 drives the malfunction prevention timer in response to the input of the insertion signal, and then proceeds to step 420. In step 420, if the time due to the malfunction prevention timer is greater than 2 sec, which is a malfunction prevention time, the process transitions to process 450 to check whether a call signal is generated by pressing the call button 10 of the earphone jack on the insertion detecting terminal 50 of the plug. In step 450, if the call signal is generated in the insertion detection terminal 50, the control unit 111 transitions to step 460 to enable the call operation counter and reset the call stop counter. Thereafter, the process transitions to step 480, and the control unit 111 determines that the call button 10 is pressed when the output value of the call operation counter is greater than 300msec, and the process proceeds to step 500 to check whether the incoming call is ringing. If the incoming call is ringing in step 500, the call button 10 is determined to be an operation for performing a call, and the process proceeds to step 510 to perform the operation required for the call and ends. If the incoming call is not ringing in step 500, the process moves to step 520 to check whether the call is in progress. When the call is in operation 520, the pressing of the call button 10 is determined as an operation for ending the call, and the process proceeds to step 530 to stop and terminate the operation required for the call.

On the other hand, if the call button 10 is not pressed in step 450, the process transitions to step 470 to enable the call stop counter and reset the call operation counter. Thereafter, the process proceeds to step 490, and when the output value of the call stop counter is greater than 100 msec, which is the call stop time, it is determined that the call button 10 is not pressed and the process goes to step 450 to detect the press of the call button 10.

As described above, the present invention starts and ends a call by attaching a call button to the earphone, and starts a call by pressing the SEND button of the portable phone itself when a call is received and presses the END button of the portable phone itself when the call ends. Discomfort to press is eliminated.
