Description

Method of receiving telephone call by remote control from telephone terminal {METHOD FOR PROCESSING INCOMING CALL BY REMOTE CONTROL IN TELEPHONE TERMINAL}

The present invention relates to a telephone reception method in a telephone terminal, and more particularly, to a telephone reception method for receiving a call on a speakerphone automatically off-hook when a user generates a sound at a ring-off time of a ring incoming signal in a telephone terminal.

Conventionally, when using a phone with a built-in speakerphone, when a call is received from the outside and a ringing signal rings, the speaker body is pressed by using the location of the telephone body or the handset is picked up to receive a call. In recent years, however, all products have rapidly developed into remote control and automation or speed eras, and they had to stop the work in progress when receiving a telephone and use it as the location where the telephone was urgently installed. And if the user is looking away from the phone when the phone rings, if the time taken to move to the location where the phone is installed is too short, the caller will not be able to answer the call quickly. There was a problem that could occur.

Accordingly, an object of the present invention is to provide a method for receiving a call by sound generation when a call is received from a telephone terminal to solve the above problems.

Another object of the present invention is to provide a method for receiving a call by automatically turning on a speakerphone by generating a sound at a ring-off time of a ringing signal when a call is received from a telephone terminal.

The present invention for achieving the above object is to receive a call by forming a speakerphone call path by inputting a sound for a speakerphone call request during the rest period of the ring incoming call signal when a ring incoming call signal is detected in the telephone terminal. It features.

1 is a block diagram of a telephone according to an embodiment of the present invention.

2 is a control flowchart for receiving a call by a speakerphone call request signal according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a telephone according to an embodiment of the present invention.

The key matrix 10 includes keys for inputting various functions and control commands, numeric keys and speakerphone keys for performing a dialing function, and outputs key data corresponding to keys pressed by a user. The CPU 20 has a built-in timer function, and receives a ring incoming call detection signal to control the speaker phone call by turning on the hook switch when a predetermined speaker phone call request signal is input during ring ringing off time. The voice processor 40 voice-processes the voice signal for the call connected to the trunk line. The microphone 100 inputs a voice signal. The speaker 90 outputs an electric voice signal as an audible signal. The first and second amplifiers 70 and 80 amplify and output the input / output signals of the microphone 100 and the speaker 90 to a predetermined level. The ring detector 30 detects a ring received from the trunk line and provides the ring to the CPU 20. The hook switch 50 performs a hook on / hook off switching operation of the telephone line under the control of the CPU 20. The A / D converter 60 receives the speakerphone call request signal, which is input from the microphone 100 and outputs from the second amplifier 80, for example, a handwriting, a rolling sound, or a shouting sound, converts the digital signal into a digital signal, and applies the same to the CPU 20.

2 is a control flowchart of receiving a call by a speakerphone call request signal according to an embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

When a call is received from the outside, the ring detector 30 detects a ring incoming signal and applies it to the CPU 20. The CPU 20 controls the ringer generating unit (not shown) so that the ringing tone is output to the speaker 90 through the first amplifier 70. At this time, the user inputs the sound generated by the speakerphone call request signal, for example, when the user taps, rolls or shouts away from the phone, through the microphone 100. Then, the sound is amplified to a predetermined level by the amplifier 80, and then applied to the A / D converter 60 to be converted into a digital signal. At this time, the CPU 20 compares the digitally converted signal with the speakerphone call request signal registered in the internal memory and determines whether the signal is identical. As a result of the determination, the CPU 20 determines that the speakerphone call request signal is detected when the speakerphone call request signal stored in the internal memory matches with the digitally converted sound signal, and turns on the hook switch 50 by the speaker 90 and the microphone 100. Allow speakerphone calls. When the call is completed, the user ends the call by pressing the speakerphone key of the key matrix 10. At this time, the CPU 20 detects whether the speakerphone key is input and controls the hook switch 50 when the speakerphone key is input to cut the call path.

As described above with reference to FIG. 2, the control operation of the CPU 20 for making a speakerphone call by inputting a speakerphone call request signal when a call is received as described above is described. Check if the call is detected. At this time, if a ring incoming signal is detected, the process proceeds to step 103. In step 103, the CPU 20 checks whether the ring incoming call off period is a pause period of the ring incoming signal. If it is not the ring incoming call off period which is the idle period of the ring incoming signal, the process proceeds to step 104 and the CPU 20 generates a ring incoming call and returns to step 103. In step 103, if the ringing call off period is performed, the CPU 20 proceeds to step 105. The CPU 20 receives a speakerphone call request signal (for example, a clapping sound or a rolling sound or a shouting sound) input through the microphone 100 and the second amplifier 80. Check if it is received through A / D converter 60. If the speakerphone call request signal is not received, the process proceeds to step 106. The CPU 20 checks whether the detection of the ring incoming signal is stopped from the ring detector 30. If the detection of the ring incoming signal is stopped, the CPU returns to the standby state of step 101. If the detection of the signal has not stopped, the flow returns to step 105. However, if the speakerphone call request signal is received, the process proceeds to step 107 and the CPU 20 controls the hook switch 50 to form a speakerphone call path and proceeds to step 108. In step 108, the user controls the voice processing unit 40 to perform a call so that the user can transmit and receive a voice signal to the speakerphone including the speaker 90 and the microphone 100. In step 109, the CPU 20 checks whether the speakerphone call key is pressed from the key matrix 10. If the speakerphone call key is not pressed, the process returns to step 108, and when the speakerphone key is pressed, the process proceeds to step 110. In step 110, the CPU 20 turns off the hook switch 50 to cut the speakerphone communication path and switches to the standby state in step 111.

As described above, the present invention, when a call is received from the telephone terminal, if a clapping, clapping or yelling sounds during the rest period of the ring incoming call signal is recognized as a speakerphone call request signal to form a speakerphone call, from outside When a call is received, there is an advantage of receiving a call remotely without lifting the handset or pressing the speakerphone key without moving to the location where the phone is installed.

In addition, even when you are busy looking away from the phone when you are ringing, you can receive the call quickly without having to move to the location where the phone is installed. There is an advantage to this.
