According to the present invention, a card holder issued by a foreign or other telecommunications company may use a service using an internationally accepted credit card or a service using a calling card that is internationally spreading when providing integrated services using an intelligent network by providing each service in an intelligent network. The present invention relates to a network interworking method capable of providing a service call when requested.

As the modern society becomes more complex and diversified, communication has become a very important place in social life, and the needs of users have changed greatly as the standard of living and the range of social activities have expanded. In response to these social changes and user needs, new communication systems and networks have emerged, and various communication services can be provided using them.

In the conventional communication service, a fixed communication method for distinguishing subscribers using a line or a terminal number is used, but a credit call service that can receive a communication service without limitation of a terminal or a place has emerged. A credit call service is a service that charges a designated billing number for a call charge used after providing a communication service with the user's credit as collateral.

Credit call services have evolved in many forms. There is a credit call service provided by the intelligent network, a credit card pay phone service by a calling card or a credit card holder using a credit card pay phone, and an international credit call service using a calling or credit card issued by an operator. Contrary to the credit call service, there is a prepaid card service that pays for the call in advance and provides communication service for the amount paid using the card payphone.

However, similar services promoted in various forms in order to facilitate the convenience of communication users are rather confusing to the user, and there are inconveniences such as using a specific terminal or restricting a callable area when using the service. There was a burden for service management and system operation management.

Credit communication services, which provide communication services based on the credit of users or subscribers, have emerged in various forms from a technical or business aspect.

FIG. 1a is a diagram of an intelligent network structure for a conventional intelligent network credit call service. In FIG. 1a, a database (DB) for a subscriber of a credit call is established in a service control point (SCP) to be credited at a service switching point (SSP). When a call service call is recognized, a credit check is made through a common line signaling network to a service control system (SCP) and the call is connected to a corresponding destination.

The structure of an intelligent network that can accommodate new and diverse services quickly and easily at the network level is composed of a service switch (SSP), a service control system (SCP), and a service management system (SMS). It performs communication between the service switch (SSP) and the service control system (SCP) through the network. The service switch (SSP) is a gateway that interconnects the existing telephone network and the intelligent network, and analyzes the calls generated from the subscribers of the existing telephone network and determines that the intelligent network service is the call control information necessary for processing the intelligent network service. After requesting service control system (SCP) through the network, the service call connected by the subscriber using the information sent. Service control system (SCP) is a database (DB) system that holds service control logic and subscriber data for intelligent network services. When receiving an inquiry about the intelligent network service call from the service switch (SSP), it performs the qualification check and translation of the call and transmits the information for call processing to the service switch (SSP). The service management system (SMS) is a system for managing a database (D) used by the service control system (SCP) to operate and manage subscriber data necessary for service control, and collect billing information by collecting statistical data from the service control system (SCP). It has a function of checking, supporting network management, and reporting on service processing failures.

The intelligent network credit calling service uses an electronic dual tone multi frequency (DTMF) telephone (including public telephones), a three-digit service identification number, a seven-digit credit number, a four-digit password, and an incoming call. The service user inputs the numbers in order, and the password and the called number can be input according to the announcement. Such a complicated telephone system has a inconvenience in that the user must enter all the numbers on a regular telephone or a public telephone.

Figure 1b is an intelligent network structure for a conventional credit card payphone service. A payphone for a credit card automatically reads a calling card or a credit card, so the user only needs to enter a password and a forwarding number to send information to the credit card processing system. It is a service to call after checking the database by transmitting.

This service can be used only in credit card payphones, and the credit card processing system 13 has difficulty in expanding services because it is accessed through a public switched data network (PSDN).

FIG. 1C is a diagram of an intelligent network structure for a conventional international credit call service, and provides a service using an international credit call processing system 24 as an international credit call service using an international calling card or a bank credit card issued by a telecommunications operator. . If you enter a service identification number, card number, password, and called number on a DTMF telephone in a general-purpose electronic telephone, the international credit call processing system 24 searches the database and checks the credit before calling. It is a service.

This service also requires the user to enter all numbers according to the numbering system and can be provided through the operator. In addition, by using the international calling card, it is possible to use international and domestic calls in foreign countries.

Lastly, the public telephone card in the form of a prepaid card has a magnetic tape attached type and an integrated circuit (IC) built-in type, but it can be used only in a public phone that can read it.

Conventional credit call services, which are provided in various forms as described above, have similar service procedures, have different usage procedures, have limitations on the user terminal and the coverage area, and have different numbers when subscribing to multiple credit call services. Because it is given to the user from the viewpoint of confusion and inconvenience to use, there is a separate system for providing various services, there was an inefficient problem in terms of operation management.

In order to solve the above problems, the present invention provides a call card holder or a foreign issued credit issued by a foreign or other communication service provider when providing a service by integrating pseudo credit call services and prepaid card service in an intelligent network. The purpose of the present invention is to provide a network interworking method for smoothly performing credit inquiry through network interworking between nations or telecommunication operators when a cardholder requests a service.

In order to achieve the above object, the present invention, in the network interworking method of the credit call integration service applied to the intelligent network, by analyzing the service call requested for the credit call integration service if additional information is required to request the user Performing a credit check after collection, and immediately performing a credit check if no additional information is needed; A second step of performing a credit check after requesting and collecting additional information from the user when the credit check result is a domestic issued card and needs additional information, and performing an incoming call processing when the credit check is made and the additional information is not needed; And if the credit check result is a card issued by another country, request a credit check to the other country and receive the result, and if additional information is needed, the user requests additional information and collects the credit check. And a third step of performing the process.
