FIG. 2A is a diagram illustrating an example of a display screen of a list of a plurality of advertisement companies provided by a web server in a voice call service system and method using the Internet according to the present invention, and FIG. 2B is illustrated in FIG. 2A. FIG. 1 illustrates an example of a screen displayed when a user selects an advertisement company among a plurality of advertisement company list companies.

First, the web server system 20 is a database of a plurality of contract information of each advertising company contracted in advance and the advertising information provided by each company is a database, the user logs the user system (U ₁ -U _n ) When accessing the web server system 20, the web server system 20 provides the list information for each advertising company in the database to the user system (U ₁ -U _n ) through the Internet. Accordingly, the user systems U ₁ -U _n display the advertisement company list information as shown in FIG. 2A.

When a plurality of advertisement company list information is displayed as shown in FIG. 2A, the user selects one advertisement company to be voice-called, and when one advertisement company is selected, the user system U ₁ -U _n is a web server system 20. ), The detailed information about the advertising company and the phone call function are requested through the Internet network. Here, the detailed information about the advertisement company is advertisement information.

Therefore, the web server system 20 provides the user system U ₁ -U _{n with} advertisement information for the advertisement company selected by the user according to the user system U ₁ -U _n , and information enabling phone calls. It is displayed as shown in FIG. 2B. That is, as shown in FIG. 2B, the name of the advertisement company selected by the user is displayed on one screen, and the advertisement screen for the corresponding advertiser is displayed on the other side, and the voice call through the Internet network between the advertiser and the user is displayed on the other side screen. A phone call selection button is displayed to make a call.

When the user clicks the call button while the screen as shown in FIG. 2B is displayed, the call connection request data with the advertisement company is transmitted to the gateway system 30 through the Internet.

The gateway system 30 generates a DTMF signal corresponding to the telephone number of the corresponding company selected by the user according to the call connection request data from the user system U ₁ through U _n , and the generated telephone of the corresponding company is generated. The DTMF signal corresponding to the number is transmitted to the switching system 50.

The exchange system 50 transmits a call connection signal, that is, a ring signal, to a telephone of a corresponding company according to the DTMF signal transmitted from the gateway system 30, thereby allowing the user system U ₁ to U _n and the corresponding advertisement company selected by the user. The call connection will be made during the phone call.

After the call connection is made, if the telephone of the advertiser is hooked off, a voice call is made between the user and the advertiser. At this time, the exchange system 50 detects the hook-off signal of the telephone of the advertising company and provides it to the gateway system 30. Therefore, the gateway system 30 counts the talk time from the hook off point of the telephone.

When a voice call is made, the voice signal to the user is transmitted to the gateway system 30 as voice packet data through the Internet network, and the gateway system 30 corresponds to the voice packet data corresponding to the user voice signal received through the Internet network. Is converted into PCM data and transmitted to the exchange system 50.

The exchange system 50 is to provide PCM data provided by the gateway system 30 to a corresponding advertisement company telephone through a public public telephone network (PSTN) network.

In addition, the voice signal input from the telephone of the advertising company through the general public telephone network, that is, the PCM signal is provided to the gateway system 30 through the switching system 50, and the gateway system 30 is provided from the switching system 50. The PCM signal corresponding to the voice signal of the telephone company of the advertising company is converted into voice packet data and provided to the user system U ₁ -U _n through the Internet network. Therefore, a voice call is made between the user and the advertising company. That is, the gateway system 30 vocodes the voice packet data transmitted from the user systems U ₁ -U _n through the Internet network to the switching system 50 and provides the switching system 50 to the switching system 50. The PCM signal transmitted from the _N -B is vocoded as voice packet data and provided to the user system U ₁ -U _n through the Internet.

As such, when the voice call between the user and the advertising company is completed and the receiver of the telephone of the advertising company is hooked on, the switching system 50 detects the hook-on signal of the telephone and provides it to the gateway system 30.

The gateway system 30 stops the talk time counting according to the hook-on signal provided to the switching system 50, and generates the billing information corresponding to the counted talk time, and sends the generated billing information to the billing information database 40. Save it. At this time, the billing information is stored for each advertising company, the billing information to be stored is a database of the advertising company, the sender and call time information. Here, the billing information databased in the billing information database 40 is later required only by the advertising company, and the advertising company pays only the call line charges proportional to the talk time to the web server. That is, the user can make a phone call with the advertising company for free, and the advertising company only pays the telephone call fee with the user instead of displaying the advertisement on the web server system 20 free of charge.

The voice call service method using the Internet according to the present invention corresponding to the operation of the voice call service system using the Internet as described above will be described step by step with reference to the accompanying drawings.

First, when the user system is logged in and connected to the web server system (S101), the web server system provides the user system with list information about a plurality of pre-registered advertisement companies through the Internet network and displays the information (S102).

If you select the desired one among the displayed list of advertisers, the web server system displays databased advertisement information about the selected advertisers and telephone call selection information that enables the phone calls with the advertisers through the Internet. Provided to the user system (S103). Therefore, the user system displays advertisement information and telephone call selection information for the corresponding advertisement company transmitted from the web server system on the screen.

When the user selects the telephone call button to view the displayed advertisement screen and makes a phone call with the corresponding advertisement company, a call connection with the corresponding advertisement company is requested (S104).

When a call connection is made between the user and the advertising company, a voice call is made between the user and the telephone receiver of the advertising company (S105).

Then, when the voice call is completed, the billing information corresponding to the voice call time is generated, and the generated billing information is made into a database, and the call line fee is requested to the advertising company according to the billing information databased at predetermined intervals. S106).

The above method will be described in more detail and step by step with reference to FIGS. 4A to 4B.

4A to 4B are detailed flowcharts illustrating operations of a voice call service method using the Internet according to the present invention.

First, the list information of a plurality of pre-registered advertising companies and the advertising information for each advertising company is databased in the web server system (S201).

As described above, it is determined whether the user system is logged in in a state where information on each advertising company is databased (S202).

As a result of determination, when the user system is logged in, that is, when the user system accesses the web server system, the web server system searches a database and transmits a plurality of advertiser list information (advertiser list page) to the user system. The display is displayed as shown in FIG.

In operation S204, it is determined whether an advertisement company is selected from the user from the displayed advertisement company list information.

As a result of the determination, when an advertisement company is selected, the user system requests an advertisement screen for the advertisement company selected by the web server system and a selection screen for making a phone call with the advertisement company (S205).

According to the needs of the user system, the web server system analyzes the database and provides an advertisement screen about the advertisement company selected by the user and a telephone call selection screen that enables one-click phone call with the advertisement company. As shown in the user system (S206).

The user determines whether to make a phone call with an advertisement company corresponding to the advertisement screen based on the displayed advertisement screen, and determines whether a phone call button is selected for a phone call with the corresponding advertisement company (S207).

If the phone call button is not selected and you want to see the advertisement screen of another advertising company, click the previous screen selection button. When the previous screen selection button is clicked, the screen as shown in FIG. A plurality of advertisement company list screens are displayed.

However, if the telephone call button is clicked in step S207, the call connection request signal with the advertisement company selected by the user is transmitted to the gateway system through the internet network (S208).

According to the call connection request signal of the user system, the gateway system generates a DTMF signal corresponding to the telephone number of the corresponding advertisement company and transmits it to the switching system (S209).

The exchange system transmits a ring signal to the telephone of the advertising company according to the DTMF signal transmitted from the gateway system to perform a call connection between the user and the advertising company (S210).

After the call connection is made, it is determined whether the telephone receiver of the corresponding telephone of the advertising company is hooked off (S211).

As a result, if the handset of the telephone of the advertising company is hooked off, it is determined that the voice call is made between the user and the advertising company to count the talk time from the hook off point of the handset (S212).

While the voice call is made between the user and the advertising company, the exchange system determines whether the telephone receiver of the telephone of the advertising company is hooked on (S213).

If the telephone receiver is not hooked on, it is determined that the voice call is continuously made between the user and the advertising company, and the counting time is continuously counted. If the telephone of the advertiser is hooked on, the telephone call is made between the user and the advertising company. It is determined that it is completed to generate the billing information corresponding to the talk time counted to date to make a database (S214). The database charge information is used to request the charge rate for the call line at a predetermined period.

Here, let's briefly look at the voice call method between the user and the advertising company.

First, in a state where a call connection is made between a user system and an advertiser, a voice call is made from the time when the telephone of the advertiser is hooked off. The voice signal input by the user through a microphone is converted into voice packet data in the user system. It is transmitted to the gateway system through the internet network.

The gateway system converts the voice packet data corresponding to the user voice signal received through the Internet network into PCM data and transmits it to the switching system.

The switching system is to provide PCM data provided by the gateway system to the corresponding advertising company telephone through the public public telephone network (PSTN).

And, the voice signal input through the public payphone network, that is, PCM signal from the corresponding advertising company telephone is provided to the gateway system through the switching system, the gateway system corresponding to the voice signal of the telephone call of the advertising company telephone call provided by the switching system It converts the signal into voice packet data and provides it to the user system through the Internet. Therefore, a voice call is made between the user and the advertising company. That is, the gateway system vocodes the voice packet data transmitted from the user system through the Internet network to the PCM signal and provides it to the switching system.The gateway system vocodes the PCM signal transmitted from the switching system into the voice packet data to provide the Internet network. Is provided to the user system through.
