Description

The system and method of a internet phone, capable of oneclick communication with an appointor on website}

The present invention relates to an Internet telephone system and a method in which a user can make a one-click call with a designated party when searching the Internet. More specifically, the present invention relates to a company, a school, and a public office, in which the user has a Private Branch eXchange (PBX). If you want to access more information from the website operated by the company (hereinafter referred to as 'Company'), please click on the internet phone interface installed on the web page to access the website. The present invention relates to a one-click Internet telephone system and method using only a pure network without using a public switched telephone network (PSTN) that enables direct communication with a working group.

In general, in order to make a call with a remote party, the call can be divided into a general telephone connected to a public telephone network and an internet telephone connected to an internet network. Currently, the Internet is not limited to a specific field and is widely used. As the number of Internet users using the Internet is rapidly increasing as a part of real life, the number of service providers that provide specific services to the Internet users is increasing rapidly.

In the case of conventional telephones, data transmission is carried out through a line transmission method. In this line transmission method, a single telephone line is exclusively occupied by both callers so that voice and fax data can be transmitted and received and shared by a third party. If a large number of users call in the same time period, the line usage fee will naturally increase due to a limited telephone line, and this increase in line usage fee will be reflected in the telephone bill. In addition, since the line transmission method transmits and receives while maintaining the data size of the phone as it is 64Kbyte, the price per unit capacity within a certain amount of line capacity naturally increases, so that the telephone fee that users must bear in long distance calls such as international calls or long distance calls Is of course high.

Due to the high phone charges incurred when using existing telephones through such line transfer methods, interest in Internet telephones using packet transfer schemes has recently increased. Packet transmission schemes do not occupy a specific line but are basically a line. By sharing the data, the data is divided into packets in the form of packets, and the packets of different characteristics can be transmitted simultaneously on one line, so they can be shared without occupying one line. Internet phone using packet transmission method is cheap because of low cost because the usage fee for line is mutually distributed and the transmitted packet is compressible data. Internet calls from all over the world due to usage fees Technology is putting power to the prefecture.

The efforts of these countries to make Internet telephony have resulted in H.323, a technical guideline for compatibility between voice communication products on the Internet, that is, for multimedia communications including audio, video, and data over LANs where quality of service is not guaranteed. The proposed standard was proposed by the Study Group 15 (SG15) under the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) in 1996 and approved by the World Telecommunication Standardization Conference (WTSC). H.323, the standard that is secured by Voice over Internet Protocol (VoIP), includes G.723, G.729, and other standards related to voice compression, including RTP / RTCP (Real Time Protocol / Real Time Control Protocol). The technical content of H.245, a standard for control, including H.225 and Q.931, which are related to It is adopted as a standard of anger.

There are various types of internet phones operating on the basis of the H.323 technology, such as PC-to-PC, PC-to-phone, and telephone-to-phone. Let's take a look at the technical contents and problems of.

As shown in FIG. 1, user A basically uses a public telephone network and an internet network to make an Internet phone call with user B in another country. User A first uses the public telephone network to access the Internet through his / her telephone. When a telephone identification number or Voice over Internet Protocol (VoIP) gateway access number is pressed, this number is converted into a DTMF (Dual Tone Multi-Frequency) signal type and transferred to the local telephone company's telephone exchange to which User A's telephone is connected. The exchange interprets the received signal and transmits it to the gateway gateway of the corresponding country, and the gateway gateway transmits the signal to the VoIP gateway A.

The VoIP gateway A consists of software that performs the signaling protocol and hardware that processes the actual signal.The MFC-R2 protocol, which is a protocol between PCM, which is a data format used in a public telephone network, and exchanges specified for signaling, is used on the Internet. Unlike the above, the signal cannot be interpreted by the router, so it receives the signals and data transmitted from the telephone exchange and converts them into a form that the router can understand. Transmit signals and data

The VoIP gateway B, which has received the signal through the router B, converts the signal transmitted by the reverse method of signal processing of the VoIP gateway A into a form that can be recognized by the gateway exchange of the other station or the local telephone exchange. If the signal is transmitted to the exchange, but the signal is transmitted to the gateway exchange, the gateway exchange transmits the signal to the local exchange as if using an existing telephone network, and the local exchange makes a call to the telephone number. In case of transmitting the corresponding signal to the local exchange, the VoIP gateway B calls the corresponding telephone number through the exchange so that user A and user B can make a call.

As mentioned above, the technical method of making Internet telephone call between countries will be basically the same as the internet telephone method made in one country, and in the case of PC-to-telephone, it is necessary to solve the compatibility between public telephone network and internet network. You will need a VoIP gateway. In the case of making a conventional internet call, the service fee is much lower than that of a regular phone, especially for a long distance call such as an international call or a long distance call. However, the following problems have been raised.

The first is the quality of the call. No matter how low the cost of the Internet phone, if it is inconvenient to use and the sound quality is not enough to understand what the other party is saying, the original intention of the Internet phone will be diluted. As described in the above description, an internet phone converts voice signals transmitted from a telephone network into a packet form through a VoIP gateway device, and then transmits the voice signals to the internet network according to an internet signal transfer protocol. In this case, the voice packet arrives late, resulting in a problem of delayed voice during an internet phone call.

As such, the VoIP gateway may be a factor that causes delays in Internet telephony. All operations performed at the VoIP gateway may be regarded as delay factors. In other words, the voice signal received from the exchanger is converted into a packet form, compressed by voice compression algorithm, and then transmitted through the router to the Internet signaling protocol.The VoIP gateway on the other side decompresses and decompresses the packet received from the router. As a signal transfer protocol that can be recognized, a process of transmitting a voice signal is performed. In particular, when the traffic increases in the Internet network, there is a problem that the delay of the Internet telephony call may be severe due to the throughput or speed of the gateway.

Secondly, the user's convenience. When the user connects to the VoIP gateway to use an Internet telephone, the gateway access number is about 7 to 8 digits, the subscriber number is about 10 digits, the password is about 4 digits, and the other party. If you need to dial the number in order of the phone number, and if the internet identification number is given, you need to dial the 5 digit identification number instead of the gateway access number and go through the above process. There is an inconvenience to press.

In order to solve such inconvenience, users who have received a member ID through a prescribed sign-up procedure and enter the phone number of the other party can use a computer that provides Internet telephony such as dialpad or wowcall. You can make an internet phone call with the other party through the microphone and speaker connected to the phone. However, although the above-mentioned internet phone service site puts more emphasis on user's convenience than the existing internet phone, it is still inconvenient to input the phone number of the other party after the login process in order to make an internet phone call. In particular, when a user searches for a shopping mall or a content providing site on the Internet, and inquires or other information is required, the user accesses a site providing the above-mentioned Internet telephony service and performs a login process. There is a lot of inconvenience when using the Internet because you have to dial the phone number of the company, and these Internet phone provider sites only use the Internet network, and the Internet can be provided with real-time access to other resources. Characteristics of Internet integration is not true because of the lack of integration and interworking.

Third, there is a usage fee. However, there is still a shortage of gateway devices that provide Internet telephony, compared to the existing switchboards that service ordinary telephones. There is a problem that the use fee is still expensive.

Due to this problem, when a user searches for a shopping mall or a content providing site using the Internet, the user wants to ask questions or additional information. With just a click, you can focus on the user's convenience of making an internet phone call. By using only the internet network instead of the existing public telephone network, you can solve the problem of delays and reduce the cost of the internet phone bill. There is a need for a new Internet telephony system.

The present invention has been made to solve the above-mentioned conventional problems, when the user accesses a website operated by a company equipped with a private branch exchange, etc., when searching for information, if you want any questions or additional information installed on the web page By one-click internet phone interface, you can make an internet phone call with the other party. The web page where the information is displayed when you search the internet is connected naturally with the internet phone. The purpose is to improve the convenience of the user by paying a fee in the operator.

Another object of the present invention is to improve the data processing function of the VoIP gateway device, the private branch exchange such as a user operating a computer and the Internet site is connected only to the Internet network, so that the service in connection with the public telephone network Compared to the existing Internet phone, the service cost of the Internet phone provider and the burden on the Internet phone usage fee of the general user can be reduced, so that the Internet phone call can be made smoothly and the purpose of inducing the replacement of the existing public telephone network is have.

If the other party's computer 3 is not connected to the Internet, the Internet telephone service is terminated. If the other party's computer 3 is connected to the Internet, a plug-in program for providing the Internet telephone service installed in the computer is transmitted from the user. After recognizing the call signal, the call establishment signal is re-transmitted to the user's computer 1. When the call is established through the above process, a voice channel is generated, and the user's voice signal is compressed by G.729, a voice compression standard algorithm, and transmitted to the other party's PC 3 in a packet manner. It converts the voice signal into a voice signal and outputs it through a voice output device such as a speaker or a headset connected to the computer.

In addition, when the one-click Internet telephone interface unit 10 is installed in a predetermined Internet site as described above, the one-click Internet telephone service using the existing public telephone network of the PC-to-phone system is also possible. After registering the encrypted counterpart identification number containing the information on the counterpart in (10), when the user searches the website, the user clicks on the one-click Internet telephone interface unit 10 to perform the process shown in FIG. Going through. At this time, if the other party's telephone 2 is not connected to the private branch office switching network by interpreting the other party's identification number, the Internet telephone server unit 30 may be associated with the local exchange 50 of the corresponding area where the other telephone is located. By transmitting the information on the telephone number of the other party's telephone (2) to the VoIP gateway C unit 22 through a predetermined conversion process, it transmits a dial tone signal and a voice signal to the local exchange 50 of the corresponding region.
