Description

Telephone terminal device capable of talking on speakerphone using remote controller and its control method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone terminal apparatus method, and more particularly, to a telephone terminal apparatus capable of a speakerphone call using a remote controller for driving a speakerphone call using a remote controller and a method of controlling the same.

In general, a telephone terminal device having a speakerphone and on-hook dialing function can be operated by dialing only by operating a key attached to the set, and in a hands-free device, a part corresponding to a dial operates a key mounted on the set. You can only make calls. Therefore, such a conventional telephone terminal device has an inconvenience of moving to a location where a telephone terminal is installed in order to make a call or receive a call.

Accordingly, an object of the present invention is to provide a speakerphone call method using a remote controller capable of performing a speakerphone call using an infrared remote controller in a telephone terminal device.

Another object of the present invention is to provide a speakerphone call method using a remote controller capable of performing speakerphone calls by dialing by an infrared remote controller in a telephone terminal device.

In order to achieve the above object, the present invention provides a method for controlling a speakerphone call remotely by using the remote control in a telephone terminal device having a remote controller and a remote control receiver, the method comprising generating a speakerphone on signal and a numeric key signal from the remote controller. And remotely receiving the generated speakerphone on signal through the remote controller receiver to turn on a speakerphone, receiving a numeric key signal generated from the remote controller after the speakerphone is turned on, and performing dialing; After the dialing is performed, a process of performing a call by forming a call path when there is a response from the counterpart.

2 is a control flowchart for making a voice call of a telephone by remote control of a remote controller 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 terminal device according to an embodiment of the present invention.

The remote control transmitter 10 generates an OHD key, a speaker phone key, and a dial signal, converts the code into a code using a pulse position modulation (PPS) method, modulates the transmitted signal, and transmits the infrared signal. The remote controller 12 receives the infrared signal received from the remote controller 10 and converts the infrared signal into a current. The signal converter 14 amplifies the current output from the remote controller receiver 12 and performs waveform shaping. The signal converter 14 decodes the waveform-shaped signal and outputs a remote controller code string signal. The central processing unit 16 controls the telephone terminal function and controls the phone to turn on the speakerphone according to the infrared key input from the signal converting unit. The dialing unit 18 dials the telephone number under the control of the central processing unit 16. The line interface unit 20 is connected to a public telephone network through a telephone line, and interfaces ring signals, tone signals, and call voice signals between the telephone and the public telephone network. The speech circuit 22 is connected to the microphone 32 and the speaker 34, and processes the voice signal to turn on the speakerphone under the control of the CPU 16. The AUX unit 24 matches and outputs audio levels and impedances suitable for external devices. The audio amplifier 26 amplifies and outputs the audio signal input through the line interface unit 24 or the audio signal input from the external audio device to the measure level. The speaker driver 28 outputs the audio signal output from the AUX unit 24 to the speaker 30.

2 is a control flowchart for making a voice call of a telephone by remote control of a remote controller according to an exemplary embodiment of the present invention.

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

When the user presses the speakerphone (SPK) key provided in the remote control transmitter 10 at a distance from the telephone terminal device, the speakerphone on key signal generated from the remote controller transmitter 10 is converted into a code by PPS (Pulse Position Modulation) method. After conversion, it is modulated and transmitted as an infrared signal. At this time, the remote control receiver 12 receives the infrared signal transmitted from the remote control transmitter 10, converts it into a current, and outputs it to the signal converter 14. The signal converter 14 amplifies the current output from the remote controller receiver 12 and then waveform-forms the signal converter. At this time, the central processing unit 16 checks whether the speakerphone (SPK) on-key signal is input from the signal conversion unit 14 from the remote controller transmitter in step 101 and proceeds to step 102 when the speakerphone (SPK) on-key signal is input. In step 102, the central processing unit 16 controls the line interface unit 20 and the speech circuit 22 to turn on the speakerphone. When the speakerphone is turned on, a dial tone is heard through the speaker 34. In this case, the user remotely inputs the numeric key of the key through the remote controller 10 for dialing. In step 103, the CPU 16 checks whether the numeric key signal is input from the signal converter 14. When the numeric key signal is input, the process proceeds to step 104 and the central processing unit 16 controls the dialing unit 18 to dial the input number. At this time, when the ringback tone rings through the speaker 34 and the other party picks up the handset and hooks off, a voice call is made in step 105.

In the exemplary embodiment of the present invention, an operation of making a voice call using the remote controller has been described as an example. However, in another embodiment of the present invention, a speakerphone is placed on the original glass after placing an original on a document glass in a facsimile apparatus having a remote controller. Turn on the key and press the number key. In this case, the facsimile apparatus that receives the infrared signal generated from the remote control transmitter 10 may transmit a fax document by dialing a number corresponding to a numeric key.

As described above, the present invention is convenient to use because the remote control to make a speakerphone call when a call is received using a remote control for a general television, and after registering a desired phone number on the remote control, the speakerphone is remotely controlled by the remote control. After turning on and dialing the registered telephone number to make a call there is an advantage to improve the function of the telephone terminal.
