Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a public telephone service system using a PSTN network according to the present invention, which includes a public telephone 10, a PSTN network 20, an outgoing gateway 30, an internet network 40, and a gatekeeper (Gatekeeper) 50), billing system 60, and destination gateway 70.

The public telephone 10 is a conventional coin-operated telephone, which is connected to the PSTN network 20, and when a user presses a country selection number, an area code, and a phone number in order for an international call, the payphone 10 is automatically connected to the corresponding access code according to the country code. ACR (automatic call router) function with a built-in routing table to connect, an interface device that connects to an Internet gateway when a user dials an access number such as a general phone number or 080 number including area code, and call time by country. It calculates the balance by calculating the fee according to the, and has a balance calculation function with a built-in currency rate table for each country to display it to the user.

At this time, the public telephone 10 provides a country-specific rate setting function that allows the operator of the establishment where the telephone is installed to arbitrarily set the country-specific usage rate, so that the amount of money input by the user to the phone can be reduced according to the talk time. Make sure

The outgoing gateway 30 is a device that serves as a relay that connects the PSTN network 20 and the Internet network 40 to support real-time two-way communication, and forms of media such as transmission format, communication procedure, and audio transmitted from the PSTN exchange. The inconsistency in the image.

In addition, by compressing the voice signal transmitted from the PSTN switch before transmitting to the Internet network 40, a bandwidth for transmitting one person's voice in the general telephone network so that the Internet network 40 can deliver more than eight people voice. I use it.

The gatekeeper 50 is a device that registers, authenticates, and manages bandwidth of the outgoing gateway 30. When the outgoing gateway 30 requests the use authentication using the access number and the calling party number, the gatekeeper 50 is connected to the switch according to the access number. It issues a connection gateway address to be described below, and completes a call through a call detail record (CDR) when a call is completed.

The billing system 60 records the call history of the customer (installer) using the PSTN public telephone service to settle the fee, and uses the monthly billing method to send the billing bill.

The destination gateway 70 is a device that serves as a relay that connects the Internet network 40 and the PSTN network 20. The counterpart number dialed by the user through the public telephone 10 in conjunction with a PSTN exchange of a domestic or overseas communication service provider. For example, a call is relayed to a general telephone, a public telephone or a mobile telephone.

2A and 2B show an operation flowchart of a public telephone service using the PSTN network 20 according to the present invention.

First, when a user who wants to make an international call puts a 100 won or 500 won coin into the coin inlet of the public telephone 10, a message "Press the country selection button" is output through the handset of the telephone (101). ).

For example, if you want to make a call to the United States, call 1 (102), the ACR device automatically dials the access number corresponding to 1 (103). If not, dial the connection number from the route table in order to connect.

At this time, while the ACR device automatically dials the access number and accesses it, the telephone outputs a prompt message "Press the area code and the other party's phone number" in order to obtain an access time from the user (104).

When the user presses the other party's telephone number (area code + telephone number) according to the guidance (105), the telephone number is temporarily stored in the interface device of the telephone (106), and the outgoing gateway 30 accesses the connection transmitted from the PSTN exchange. The number (telephone number) and the calling party number are transmitted to the gatekeeper 50 to request use authentication (107).

The gatekeeper 50 checks the access number and the calling party number (108) and notifies the originating gateway 30 whether the authentication is used (109).

As a result of the check, if it is not possible to issue the use certificate, the process returns to step 101 and outputs a guide message so that the user can press the country selection button again, and if the use certificate is issued, the destination gateway connected to the exchange according to the access number ( 70) issue the address (110).

Accordingly, by dialing the access number of the other party stored in the interface of the public telephone 10 (111), the outgoing gateway 30 connects the destination gateway 70 address issued from the gatekeeper 50 to connect the call. (112).

After the user completes the call (113), the call is processed through the CDR (114), and after calculating the call charge according to the talk time counted by the public telephone 10 (115), the balance is refunded to the user ( 116) Complete the operation.

At this time, the service charge settlement of the public telephone 10 connects the user's telephone call and at the same time counts the user's call time, and calculates the call charge based on a country-specific rate table set by the operator of the business. At the same time, the fee charged to the public telephone 10 is subtracted and displayed on the display unit to recognize the available amount of money to the user.

Thereafter, in order to settle the service usage fee of the public telephone installation operator, the billing settlement system 60 records the call history of the PSTN public telephone and settles the fee, and the usage fee is charged to the operator monthly using the end-of-month settlement method. Send it.

In addition, the public telephone service according to the present invention can be accessed by calling a general telephone number in the local or suburban area when making a domestic call as well as an international call. After installing the gateway, you can connect to a regular phone number to make a call.

The present invention has been described by way of example only a call between the phone and the phone, but is not limited to this, for example, to connect the Internet phone call to the other party's computer directly in the Internet network 40 through the destination gateway 70 Within the scope of the technical idea of the present invention, various changes and modifications can be made.

As described above, the present invention has the following effects.
