Abstract

PURPOSE: A system for having functions of internet phones/telephones/sound cars and an electronic mail alarming function is provided to make computer users pick up phones by clicking mouses while working on computers without pressing on-hook switches, and to display telephone numbers on computer screens when the users originate calls, so as to prevent the users from inputting wrong telephone numbers. CONSTITUTION: A controller(100) performs various operations through a micro processor. A switch(101) automatically switches a head set to a sound card connector or a telephone connector by operations of a telephone circuit. A telephone transceiver(104) connects the head set with a telephone line, when a user presses a hook switch or a telephone function using signal is generated from a computer. A serial communicator(103) performs serial communication between the controller and the computer. The serial communicator responds to a signal of the telephone line, and transmits a control signal to a computer body to display the signal of the telephone line on a monitor. The serial communicator controls a whole system to output a window outputting a system state.

Description

Internet phone / telephone / sound card / e-mail alarm system using serial connection between computer and telephone}

Integrate computers and phones that perform the essential functions of the information society so that users can have a better experience.

The present invention relates to a special telephone incorporating a microprocessor in the telephone so that the computer and the telephone can communicate. It is a device that makes a phone call with a single mouse click even when a user who uses a computer does not manually dial while searching the Internet, an organization chart or an address book.

Special telephones similar to the present invention are simply connected to the sound card of the computer / microphone jack. This way you can't communicate with your computer, so you can't use the various features available on your computer directly from your phone.

1 is a block diagram schematically showing a telephone in which only the ear / microphone jack of a sound card is connected to a general telephone function as described above.

As shown in the related art, the conventional special purpose telephone includes a telephone circuit unit 1 with a built-in telephone call receiver, a switching unit 2 that switches to a telephone and a sound card according to a user's selection, and a telephone transceiver that connects a telephone line and a headset. (3) and the sound card connection (4) connecting the sound card and the headset.

The usage is the same as a normal phone, and it is usually connected to a sound card, and then it is switched to a telephone line transmission mode through the switching unit.

The keyboard of the prior art is merely a built-in sound card connection jack in the phone, so when the computer user turns off the phone, when the surroundings are disturbed, when using multiple phones, the bell signal is not only known. There is no way to check if the number is entered correctly. In addition, there is a problem that does not have a communication function with the computer, address book management available on the computer, dialing while searching the Internet, mail notification, press number output and the like.

The object of the present invention is to solve the problems described above, if a person who works with a computer selects and clicks a phone number while searching an address book or an organization chart, the call is made and if there is a number to be called while searching the Internet, Select and click to make a call automatically, ring the bell to notify the user when a call is received or when an e-mail arrives, and print out the e-mail or call time on the computer screen. To improve the mutual function of.

You can also make calls using the numeric keyboard on your computer keyboard, so you don't need a key-in on your phone.

In the system according to the present invention to achieve the above object, the power supply unit for transmitting power from the computer to the system and the sound card connection unit and the telephone connection unit that can be adjusted by the program control unit for connecting the computer sound card and the headset There is a sound card connection, a telephone transceiver to connect the telephone line and the headset, and a serial communication unit for communication between the computer and the system.

In order to achieve the above object, (1) when using a computer, the computer gives commands to the system first, (2) when the system is giving commands to the computer while using the computer, and (3) When used, the system may give commands to the computer.

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

2 is a block diagram schematically showing the configuration of a system having an information display function for a call according to the present invention.

The controller 100 receives power from the power supply and performs various operations through the microprocessor. Control of the operation for all functions of this system is executed in this control unit.

The switching unit 101 automatically converts the headset into a sound card connection unit or a telephone connection unit by an external signal or a telephone circuit unit.

The telephone transceiver 104 serves to connect the headset with the telephone line when the user presses the hook switch and when the telephone function use signal is received from the computer.

The serial communication unit 103 enables serial communication between the control unit 100 and the computer and transmits a control signal to the computer main body 200 in order to display the contents on the monitor 300 in response to a signal input from a telephone line, Control the entire system so that a window displaying the system status is displayed. In addition, the system controls the system to display the window as described above when searching the internet or sending a phone number from the desktop.

The operation of the telephone system having a special function according to the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

3 is described in more detail with reference to the accompanying drawings, the operation of the telephone system having an information display function for a call according to the present invention.

As shown in the figure, first, in the off-hook determination state (S100), the telephone circuit unit 102 determines whether the transmission / reception mode is a transmission / reception mode, and receives data and performs the dialing. .

After determining first whether the telephone reception mode is W10, and outputs a telephone notification animation screen to the monitor when the telephone reception mode is received (W20). If it is determined that reception (W30) is received, the animation is deleted from the screen, and if it is not received, the time when the call is received is displayed on the screen (W40).

Next, after determining whether it is the e-mail mode W50, the e-mail receiving server and the reception time are displayed on the monitor screen in the e-mail mode (W60).

If it is in the telephone call mode (W70), it is determined whether it is the keyboard input mode (W80), and in the keyboard input mode, it is determined whether it is the end (W100) after transmitting DTMF tones (W90). do. In computer input mode (W110), DTMF tones are output continuously until the end (W130).

The communication between the computer and the terminal is performed according to a certain rule, and the command between the two systems and the command to be performed are determined by a unique communication method determined by the telephone system.

As described above, this telephone system allows users who use a computer to make or receive phone calls with the click of a mouse when working with a computer, and to send or receive a telephone without pressing an on-hook switch. none.

In addition, the present invention has the advantage that the phone number is displayed on the screen at the time of the outgoing to reduce the error that the user incorrectly enters the phone number to prevent the load on the telephone station itself and save the telephone bill.

Because phone numbers are managed on a computer, you can easily recall and use frequently used numbers, increasing work efficiency.

Although the above has been described with reference to the preferred embodiment of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. I can understand that.
