Description

The internet phone apparatus

In the context of the widespread use of the Internet and computers, many Internet services such as Internet shopping malls, e-commerce, and Internet telephony are rapidly spreading. In particular, the number of Internet phones is increasing at a tremendous speed not only in the United States but also in Korea due to the advantage of being able to make free local, long-distance and international calls using the Internet. However, in the conventional Internet phone service environment, since the telephone user uses the ear / microphone connected to the sound card of the computer, the behavior radius of the user is limited, and there is an inconvenience of dialing using a mouse for the telephone connection. There are three types of Internet phones currently known: computer to computer, computer to phone, and telephone to phone. In the computer, the computer form is commonly called the Internet telephone. The call route is connected to the server for selecting the call partner when the caller executes the software for the Internet phone installed in the computer, and his Internet protocol address is registered in the server. When a counterpart of the user registered in the server is selected, a call path is established between the two sides via the Internet. In particular, if the Internet protocol address of the other party is known, direct connection is possible without going through the server.

In the form of computer to telephone, telephone users use a telephone network gateway to replace the telephone user because there is no software for Internet telephony. In particular, the telephone network gateway converts Internet protocol packet signals into analog voice signals and vice versa. The call path is connected to the gateway via the Internet when the computer user runs the software. If you enter the called party's phone number, the gateway uses it to call the called party's phone.

Telephone-to-telephone type uses a telephone network gateway like computer-to-telephone type. The calling party and the called party make a call through the gateway. Calling method is similar to the international callback service. If the caller enters the other party's phone number after accessing the gateway closest to the calling party, the calling gateway is established by searching the gateway closest to the called party through the Internet. . The called gateway is dialed again using the telephone number sent from the calling gateway. At this time, the signal between the gateway and the telephone is an analog voice signal, and the signal between the gateway is an internet protocol packet.

The voice encoding method of the Internet phone serviced in such a form mostly uses the adaptive PCM series, and the connection control protocol uses a proprietary method or H.323 method for each developer. And the voice board for the interface with the telephone user is using a sound card or a separate sound card installed in the computer.

The present invention is to provide a telephone terminal dedicated to the Internet as if an Internet telephone user is talking using a general telephone, and the Internet telephone terminal proposed here is directly connected to an input / output port such as a serial port of a computer. The telephone terminal includes a digital voice codec for converting an analog voice signal into a digital signal, a keypad for dialing numbers, and a data processor for transmitting a dial signal to a computer. The computer analyzes digital voice data and number data and connects to the Internet telephone. The Internet software control unit converts telephone connection data and voice data such as telephone number and voice data received through a terminal and a computer into a data format required by the Internet environment, and transmits and receives data to and from the Internet telephone service center.

In order to achieve the above object, an embodiment of the Internet telephone apparatus according to the present invention will be described in detail.

1 shows a shape constituted by an Internet telephone apparatus to which the present invention is applied. (1) is an Internet telephone terminal used when a user uses an Internet telephone through a computer, and is connected to a serial port of the computer via a wired cable or transmits data through a wireless modem provided in the terminal and the computer. . (2) is a control software block installed in a computer for transmitting and receiving data between the user's transmitting and receiving terminal and the computer, and functions as a resident program of the computer to connect to the Internet and to connect a telephone to an Internet telephone terminal. A wireless modem unit added to the wireless modem unit performs a function of wirelessly transmitting data transmitted between a telephone terminal and a computer.

2 is a diagram showing the configuration of an Internet telephone terminal and a connection with a computer. (1) is a keypad provided in the Internet telephone terminal to perform a function of dialing a telephone number. (2) is a voice codec which converts voice data transmitted and received as a digital signal through a computer into an analog form and converts the subscriber's voice signal into digital. (3) is an interface for connecting an Internet telephone terminal and a computer. (4) is a processor for control signal processing embedded in the terminal, which controls each component block and performs a function of converting a data signal format or analyzing voice and number data. (5) A wireless modem unit attached to a terminal, which transmits data transmitted between a telephone terminal and a computer wirelessly so that it can be used like a general wireless telephone.

The use of the present invention has the convenience of allowing users to use Internet telephony, such as using a regular telephone.
