The present invention relates to a method for integrating and providing a credit call service by integrating each credit call service into an intelligent network.

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 is 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, wherein a database (DB) for a subscriber of a credit call is built in a service control point (SCP) to provide a credit call at a service switching point (SSP). When the service call is recognized, the credit check is performed through the common line signaling network to the service control system (SCP) and the call is connected to the 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. Service Switch (SSP) is a switch that serves as a gateway to interconnect the existing telephone network functional networks. If it is determined to be an intelligent network service call, it analyzes the call originating from the subscribers of the existing telephone network. After requesting service control system (SCP) through the signaling network, the service call that the subscriber wants is connected by using the information sent. Service control system (SCP) is a DB system that holds service control logic and subscriber data for intelligent network service. 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 that manages the DB used by the service control system (SCP), and operates and manages subscriber data necessary for service control, and collects statistical data from the service control system (SCP) to check billing information and network. It has support for management and reporting on service processing failures.

The intelligent network credit calling service uses an electronic (DTMF) Dual Tone Multi Frequency (DTMF) telephone (including public telephones), and the user of the service in the order of three digit service identification number, seven digit credit number, four digit password, and called number. The password and the called number can be entered according to the announcement. The credit call service having such a complicated numbering system is inconvenient for the user to enter all the numbers in a general 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 that calls after checking the DB by transmitting.

This service can be used only in a credit card payphone, and the credit card processing system 13 is accessed through a public switched data network (PSDN), which makes it difficult to expand the service.

FIG. 1C is a diagram of an intelligent network structure for a conventional international credit call service. An international credit call service processing system 24 is used as an international credit call service using an international calling card or a service credit card issued by a telecommunications company. to provide. If you enter the service identification number, card number, password and destination number in the DTMF telephone, the international credit call processing system 24 searches for the DB and checks the credit before calling.

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.

The present invention devised to solve the above problems is to integrate the credit call services and prepaid card services similar to the intelligent network so that users can conveniently use a consistent service and various functions, service providers and systems The purpose of the present invention is to provide a method of providing an integrated method of providing a similar credit call service that can efficiently manage the service.

In order to achieve the above object, the present invention, in the integrated providing method of similar credit call service service applied to the intelligent network, when requesting the credit call integration service, the service is identified through the analysis of the service call and whether the service can be provided and added First step of checking whether information is needed: If the result of the first step of fraud is available, if the service is available and additional information is required, additional information is requested from the user and collected. A second step of repeating the process; And a third step of providing a service according to the result of performing a credit inquiry when the service can be provided and additional information is not needed as a result of the inspection of the first step.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

When a service user requests a credit call integration service using an electronic telephone (DTMF) telephone, the end station telephone (service originating exchange) 50 notifies the service exchange (SSP) 49 of this (61). The service exchanger (SSP) 49 identifies the service through the analysis of the requested service call and checks whether the service is available and whether additional information is required (62, 63, 64).

As a result of the inspection, if the service can be provided and additional information is required, additional information is requested from the user (65), and additional information input by the user is collected (66) to determine whether the service is provided with the additional information and whether the additional information is required After checking, the process repeats the process of checking whether the service can be provided (63) (67). At this time, the service switch (SSP) 69 collects information on the calling subscriber number, the telephone type, the line grade, and the like from the single station exchange (service originating switch) 50, and analyzes and checks them together (69).

If the service is not available in the service recognition and analysis verification process 63, the user is notified that the service cannot be provided (68), and the dismantling process for the service transmission axis is performed.

If it is possible to provide the service and additional information is not required, the credit check is performed (70). The credit check is performed at the service control system 46 or the credit card processing system 47 at the request of the service exchange 49. The service exchanger 49 classifies the service so that the calling card service and the prepaid card service are the service control system 46, and the credit card service is the credit card processing system 47. When requesting a credit check for service provision together with the service control system 46 and the credit card processing system 47 retrieves the service DB to query the credit status (70).
