The present invention relates to a smart card authentication and payment system and method for internet telephony service. More specifically, the user and smart card are authenticated when using the internet telephony service, and the talk time is checked for each internet phone terminal. The present invention relates to a smart card authentication and payment system for the Internet telephony service, and a method thereof, which enable the user to directly charge an Internet telephony service charge for a payment method provided by the smart card.

As is well known, when a normal telephone inputs a voice signal through a handset of a caller's telephone by using an exchange, the voice signal is converted into an electrical signal of an analog type and transmitted to the exchange through a telephone line, and then through the telephone line at the exchange. It is delivered as an electric signal to the telephone of the called party, and the called party's phone converts the transmitted electric signal back into a voice signal and transmits it to the handset to perform a voice call with each other.

As such, the basic principle of general telephones has been using the simple principle of transmitting analog voice signals to the called party without conversion for 100 years.With the development of information and communication technology, only the technology of exchanges is exchanged from manual exchanges to mechanical exchanges and analogues. It has just changed to an electronic exchanger and a digital electronic exchanger.

On the other hand, in recent years, due to the development of Internet technology supporting data communication, instead of transmitting the caller's voice to the receiver as an analog signal through a general telephone line, the voice is converted into a digital signal and compressed to use a data network such as the Internet and a dedicated line. Therefore, a technology and a device called VOIP (Voice Over Internet Protocol) phone, which transmits the caller's voice to the called party as a digital data signal and converts the digital compressed signal reaching the destination into an analog voice signal, can be called.

Internet phone service using the VOIP phone has the advantage that the fee is relatively low compared to the general phone, and in recent years, high quality sound has been enabled by continuous technology development of call quality. In addition, since most sections of the long-distance call, such as overseas calls through the Internet network, it is possible to smoothly transmit and receive voice data.

However, in the case of the Internet phone service using the VOIP phone, the user has to be given a separate ID and password for the billing, and there is a disadvantage in that the Internet phone service can be used only after each member authentication is completed during the call.

In addition, the billing method when using the Internet phone service of the existing VOIP phone is a method in which the user's phone service time is billed by measuring the usage time separately on the Internet phone server side and adding the phone number to a predetermined user's phone number. There is a problem that the use of the Internet telephony service is almost impossible, and the use of the Internet telephony service is relatively low even in public places where a large number of unspecified users exist.

In addition, the charging method of the PSTN public telephone installed in the public place was applied to the charge by detecting the charging pulse signal for each unit time transmitted by the local telephone exchange. However, the charging method in VOIP can take a charging method to reduce the charge by transmitting specific control data that performs the same function as the charging pulse from the corresponding VOIP server. Obstacles such as polling) and loss of control data over the network can occur.
