Each function will be described in detail with reference to the accompanying drawings for the individual functions and the actual operation process. 2 is a block diagram showing an internal configuration of a net-phone according to the present invention. Its configuration includes a microphone 204 for converting a user's voice signal into an electrical signal, a headphone 205 for converting an electrical signal into an audible sound, and a user performing non-voice communication in the form of numbers, Korean, English, and the like. An input unit 207 for inputting information, an output unit 208 for displaying the non-voice information transmitted through the network to the naked eye, and a data packet connected to the input unit 207 and the Internet network A non-voice data processing unit 206 for processing non-voice data provided from the network matching unit 201 for transmitting and receiving a signal, and converting an analog voice signal provided from the microphone 204 into digital voice data and outputting the digital voice data; A signal converter 203 for converting the digital voice data received through the network matching unit 201 into an analog voice signal and providing the same to the headphone 205; The network matching unit 201 inserts the digital voice data provided through the signal conversion unit 203 and the non-voice data provided through the non-voice data processing unit into a data packet in an Internet Protocol format. The digital voice data packet of the Internet protocol format transmitted through the network matching unit 201 is analyzed to extract the voice information from the data packet and transmit the extracted voice information to the signal conversion unit 203. In the case of voice data, the operation of the signal controller 202, the signal controller 202, the non-voice processor 206, and the signal converter 203, which extracts digital data and transmits the digital data to the non-voice data processor 206, is performed. Providing a central processing unit 209 for outputting a control signal for controlling and a program required for driving the central processing unit 209; The memory device 210 is configured to store communication information (text, video, e-mail, etc.) through a network.

The network matching unit 201 has an Internet connection function of a PC and a net-phone and transmits voice and non-voice signals to the Internet and receives voice and non-voice signals from the Internet. When communicating over the Internet, a protocol called IP (Internet Protocol) is used.

The function of the signal controller 202 is to convert the voice and non-voice data received from the signal converter 203 and the non-voice processor 206 into an IP format, and to convert the voice and non-IP data from the network matcher 201 into IP format. The voice signal is converted into a voice signal, and the voice signal is transmitted to the signal converter 203 and the non-voice signal is transmitted to the non-voice processor 206. It also performs the functions required to use an internet phone (party call, caller status check, call termination, etc.).

The process of dialing to the other party that wants to communicate is as follows. When the user dials the other party's number (IP address) through the input unit 207, the non-voice processing unit 206 collects all the party's number (IP address) input by the caller and hands it to the signal controller 202. The signal controller 202 assigns a called party number (IP address) to a destination address of the IP head part and assigns a sender number (IP address) to a source address of the IP head part to call the other party. The signal is generated and sent to the network matching unit 201. When the network matching unit 201 sends a call signal to the Internet, the caller (receiver) receives the call signal through the Internet and the callee receives his / her state (pause, busy, unable to talk, etc.). Sends a status signal to the caller. To be able to make a call normally, the called party must be idle and the called party responds to the call signal (by picking up the handset).

The signal converter 203 converts the analog voice signal from the microphone 204 into digital data and sends the signal to the signal controller 202. The signal converter 203 converts the voice digital data from the signal controller 202 into a voice analog signal and converts the headphone 205 into a voice analog signal. Send to). The microphone 204 converts a human voice into an analog voice signal, and the headphone 205 converts an analog voice signal from the signal converter 203 into a signal that can be heard by a person. The non-voice processing unit 206 functions to process non-voice data when transmitting and receiving non-voice data (text, video, e-mail, etc.) using the IP protocol. In the case of transmitting non-voice data except for e-mail, the non-voice data is received from the input unit 207 and sent to the signal controller 202. The signal controller 202 inserts the non-voice data into the data portion of the IP format and transmits the non-voice data to the receiver through the network matching unit 201. When receiving the text, the non-voice data inserted into the data portion of the IP format through the network matching unit 201 is purely extracted from the signal control unit 202, and the extracted non-voice data is output from the output unit 208. Will appear on the screen.

The input unit 207 functions to input a dial function and non-voice data. The output unit 208 functions to display non-voice data and to display this data when non-voice data is received.

3 is an external view of a net-phone according to the present invention. The call hold button 213 performs a function of suspending a call during a free Internet call and a regular phone call. The on-hook button 214 is used to make free telephone calls and landline calls without picking up the handset. The data transmission button 215 is used to transmit the data input through the input unit 207 to the receiver's telephone having the input recipient IP address. The transfer button 216 is used when a general call is received during a free phone call through the Internet or when a free call is received through the Internet while using a general phone. When the transfer button 216 is pressed, a free call through the Internet is suspended and a call using a normal phone is made. On the contrary, when a free phone call is made through the Internet during a call using a regular phone, the call is put on hold and a free internet call is made. The redial button 217 is used when it is necessary to dial again while attempting toll free or landline. Pressing the redial button 217 dials the receiving telephone number stored in the temporary storage. Using the mode switch button 218, it is possible to select a free Internet phone and a regular phone. An uninterrupted power supply is included as an auxiliary power supply to prevent power outages in certain areas to ensure that the functions of the net-phone (voice and non-voice calls over the Internet, e-mail function) are maintained normally even during a power outage. .

A method of freely transmitting and receiving voice data through the Internet using a net-phone according to the present invention is shown in FIG. 4. 5 is a signal flow diagram illustrating a signal procedure for making a free call (voice) through the Internet with a net-phone according to the present invention. When the sender picks up the handset of the net-phone and checks the initialization tone and dials the receiver number (IP address), the call confirmation signal sounds on the sender side and the call signal sounds on the receiver side. When the receiver responds, the call is made from then until the end of the call.

A method of freely transmitting and receiving non-voice (text, video, etc.) data through the Internet using a net-phone according to the present invention is shown in FIG. 6. 7 is a signal flow diagram illustrating a signal procedure for delivering a message (voice, non-voice) through the Internet to the net-phone according to the present invention. The sender creates a message to be sent to the receiver using the input unit 207, and then creates a destination using the IP address of the receiver (one or several) to send the message. If the message is large, it is divided into small messages and transmitted. When the message reception completion signal is received from the receiver, non-voice data transmission and reception is completed.

A method of voice communication with a subscriber of a general telephone (public communication network) that does not subscribe to an Internet service using a net-phone according to the present invention is shown in FIG. 8. The sender picks up the net-phone, presses the selector-only switch and dials the telephone number.

9 is a diagram illustrating a connection configuration between an internet network to which a net-phone is connected and a public telephone network to which an existing general telephone is connected. As shown, since the net-phone according to the present invention is connected to the Internet and the general telephone is connected to the public telecommunication network (PSTN), the two networks have different protocols, so communication is not possible. Put a gateway so that it behaves like the same network. When the sender dials a general telephone number with a net-phone according to the present invention, a call confirmation signal sounds at the transmitter and a call signal sounds at the receiver. When the receiver responds, the call is made from then until the end of the call.

A method of automatically connecting a general telephone when voice and non-voice communication through the Internet using a net-phone according to the present invention is shown in FIG. 10. The sender first attempts to make a free call using the Internet as an IP address to the receiving side by using the net-phone according to the present invention, and when the free call is impossible (during the receiving party's call, an error in the Internet network, etc.) The general phone number on the side can be dialed automatically by the net-phone to make a call using a public telecommunication network.

The net-phone according to the present invention of FIG. 11 has a built-in e-mail server function applying SMTP.

1. Receiving E-mail: The sender composes an e-mail through his or her PC or mobile phone, sends the e-mail to the IP of the net-phone, and the net-phone receives it and stores it in the memory of the net-phone itself. The recipient uses his PC and mobile phone to receive the e-mail on the net-phone. At this time, the net-phone operates as an SMTP receiver. In this case, the recipient's IP becomes PersonalID @ IP address or PersonalID @ Domain and is accessed via a password.

2. Sending E-mail: When a user composes an e-mail and sends it to a net-phone, the net-phone receives it, stores it in memory, and forwards it to an external recipient. At this time, the net-phone plays the role of an SMTP sender.

Net-phone distinguishes between sending and receiving sides using IP addresses. When both the sending and receiving sides use a fixed IP address, all IP addresses are determined. However, for variable IP users (such as ADSL), the IP address is not fixed. The net-phone according to the present invention is provided with a technology for enabling the use of free Internet telephones even in the case of variable IP addresses. First, the transmitting side has a fixed IP address, and the receiving side uses a variable IP address as an example. The sender sends a packet requesting the current IP address to the receiver. At this time, the transmitting side divides the IP address into the general telephone number. If the receiving party has the same general telephone number as that of the IP address request packet, the receiving side inserts its own IP address into the IP address response packet and sends the response packet to the transmitting side. When the response packet arrives from the receiver, the IP address of the receiver can be obtained.

Next, when both the sender and the receiver use a variable IP address, the sender sends a packet requesting an IP address to the IP management server since the sender must have an IP address in order to perform Internet communication. If the IP management server allocates one of the current free IPs, the sender can communicate with the Internet using the IP address. The sender sends a packet requesting the current IP address to the receiver. At this time, the transmitting side divides the IP address into the general telephone number. If the receiving party has the same general telephone number as that of the IP address request packet, the receiving side inserts its own IP address into the IP address response packet and sends the response packet to the transmitting side. When the response packet arrives from the receiver, the IP address of the receiver can be obtained.

There are two ways to get the IP address of the net-phone itself. Connected to the PC and RJ45 network matching unit 201 to store and use the IP address information in the PC in its own memory, and to send a packet requesting the IP address to the IP management server IP assigned from the IP management server There is a method of receiving an address response packet.

As described above, the net-phone according to the present invention can transmit and receive various data (voice and non-voice) through the Internet using an IP address of an existing Internet communication device without newly assigning an IP address. Not only can you directly access the Internet without a computer, you can call the receiving party with an IP address (receiving phone number) and make free Internet calls. Anyone who can use it has the effect of making free Internet calls using a net-phone.

In addition, the net-phone according to the present invention can easily transmit / receive not only voice but also non-voice (text, video, e-mail, etc.) data, and the non-voice data is not received through an intermediate medium such as an e-mail server. Since it transmits the information, it has the effect of solving problems such as information leakage, deletion, capacity limitation.
