As shown in FIG. 5, the present invention provides a process of accessing a web site of a telephone service by a person who wants to use the service (S100),

Visiting the website and applying for subscription, the process of receiving a unique subscriber ID and password (S110),

The person who subscribed to this Internet telephone service visits the web site of the operator and inputs his subscriber number and password from the operator as his subscriber number (S115) and the process of authenticating them (S120).

Each subscriber has a call limit and can receive phone service within the call limit. The phone service provides bilateral call service, multi-party call service, multi-party voice message transmission service, and the subscriber selects one of the above services on the web. Process (S125),

Customers who access the website can select a quantum call service, where quantum means a person making a call and a person receiving a call, and the subscriber enters a phone number and a party's phone number to be received on the web (S130),

Executing a call (S135),

A process in which both telephone numbers entered are transferred to the exchange (S140),

The exchange receiving the telephone number first calls the called party's phone (S145),

When the connection is complete, dialing the caller's phone number and then connecting the caller (S150),

Setting a call path (S155);

After the call is completed, the process is completed (S160).

When the subscriber selects the multi-party call service, inputting the caller and the plurality of the recipient telephone numbers (S165);

Executing a call (S170);

A process in which the entered telephone number is transmitted to the exchange (S175),

The exchange receiving the telephone number first calls a plurality of called telephones (S180),

When the connection is complete, dialing the caller's phone number and then connecting the caller (S185),

Setting a call path (S190);

After the call is made to complete the process (S200).

If you want to connect more during a call, if you enter the phone number of the person you want to talk to, add that call to that customer.

A service subscriber can select a multi-party voice message service and input a plurality of phone numbers of a person to whom the message is to be delivered after the selection (S205);

Writing a message of himself or herself as a document, or storing his voice as a file (S210);

The connection of the telephone service is charged according to the calling party's telephone number and the called party's telephone number that are requested to connect from the Internet. Billings for subscribers are divided into prepaid billing calls that are made within the subscriber's call limit and postpaid billing calls that are settled later depending on the subscriber's call volume.

The method of calculating call charges is different depending on the multi-party call service and the multi-party voice transmission service.

When a bilateral call is made, the telephone number of the caller and the telephone number of the caller are registered. The billing method calculates the call charge per unit time for each called number of all the phones connected to the exchange, and charges at the sum of the call rates per unit time.

6 is a flowchart illustrating a billing process in the case of a prepaid service.

As shown in Figure 6, the billing process is a process of calculating the available seconds by inverting the available time within the call limit possessed by the subscriber (S300),

Transmitting the calculated talkable time to the exchange (S310);

The process of connecting the communication path so that the exchange can only talk during the time (S320),

When the call is terminated before the available call time is completed (S330), the exchange transfers the call completion time for each called number to the charging system (S340);

The billing system calculates the actual call charge (S350),

The calculated call charges are subtracted from the subscriber's callable limit (S360).

If the available time elapses, the process of notifying the subscriber (S370),

Blocking the call connection (S380),

It consists of a process of charging the charge up to the talk time (S90).

In the case of postpaid charges, the actual call charges are calculated after the call ends.

In the case of a multi-party voice transmission service, billing is performed separately according to whether or not the individual call applied for transmission is successful. Only when the call is completed, the actual call amount is deducted from the subscriber's call limit.

Both of the above services can search the call data and the corresponding charge data by their subscriber number through the Internet.

FIG. 7 is a diagram illustrating a command transfer relationship between a web server and a billing server and exchangers for a voice call control service through the Internet of FIG. 4.

In order to enable this service, three system elements must be included. Among these, billing server can be a subcomponent of web server or can be independent as a separate component. The work flow between the three components for the service is shown in FIG.

In the authentication request process (S115), the web server obtained the customer information accessing the service requests the billing system to confirm whether the accessor is a subscriber of the service.

The authentication result process (S120) verifies whether there is a call limit for making a call or whether the subscriber is registered by the subscriber number, and transmits the result to the web server.

Dialing process (S135, S170, S220) receives the incoming telephone number, the outgoing telephone number and the message file from the subscriber.

Call time, phone number process (S140, S175, S225) calculates the available call time by using the dialing information transmitted by the billing system and delivers the available call time to the exchange.

The call result process (S400) delivers a message that the call failed immediately if the call fails to the transferred phone number, and delivers the time that the call was actually made to the billing server if the call is successful. If the call is unsuccessful, a series of processes from dialing to talk time and phone number may be repeated.

In the call information request process (S410), the web server may request the call history information of the subscriber from the billing system at the request of the subscriber. The requested information may be the call data (called number, calling number, call duration, call charges, etc.) may be individual call details or the sum of total call charges and the sum of payment totals.

In the call result notification process (S420), the billing server delivers the result according to the call information request.

Call fee payment process (S430) authenticates the purchase amount when the subscriber purchases his call limit amount in order to receive continuous telephone service, and updates the result to the billing server.

As can be seen from the above description, the present invention allows a person to call another person at his own expense using a system for connecting a telephone service through the Internet and a telephone system which is prohibited from making a call in a specific region when using the service method. If you want to add a call to another person during the call, you can add the call, and you can send your message to multiple people at the same time. This is possible, and it is effective to provide new information service to the general public as a service that combines the excellent user accessibility of internet and telephone service using database with convenience.
