Charging Method for Credit Call Service in Intelligent Network

The present invention relates to a charging method for a credit call integrated service in an intelligent network.

In general, 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.

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 credit call service developed in an intelligent network structure, and a database (data base, hereinafter DB) for a subscriber of credit call is established in a service control system (hereinafter referred to as SCP). When the credit call service call is recognized at Switching Point (hereinafter abbreviated as SSP), a credit inquiry is made to SCP through the common line signaling network and the call is connected to the destination.

The intelligent network credit call service uses an electronic dual tone multifrequency coding system (DTMF) telephone (including public telephones), and the service user 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. At this time, the billing information for service provision is stored in the SSP or SCP.

Such a complicated calling system has the inconvenience that the user has to enter all the numbers on a regular phone or a public phone.In the public phone, coins are returned after the service call and no charge is made to the calling card. There was a problem that there is a inconvenience to prepare a coin or card in order to.

Figure 1b is a network diagram for a credit card public telephone service. A credit card public telephone automatically reads a calling card or credit card, so the user only needs to enter a password and a called number. (Hereinafter referred to as CCPS) is a service that transmits information and queries the DB after inquiring, and billing information for service provision is managed by CCPS.

However, this service can be used only in credit card payphones, and since CCPS is accessed through a public switched data network (hereinafter referred to as PSDN), there is a problem in that it is difficult to expand the service.

FIG. 1c is a network diagram for providing an international credit call service, and is an international credit call service using an international calling card or a bank-based credit card issued by a telecommunications company.

In this service, DTMF phone including public telephone, enter 4 digit service identification number, 16 digit card number, 4 digit password and call forwarding number. As a service, billing information for service provision is managed by an international credit call processing system, and when used in a public telephone, a coin or a telephone card is required in the same manner as an intelligent credit call service.

This service also requires the user to enter all numbers according to the numbering system. The service can be provided through the operator, and the international calling and domestic calls can be restricted in foreign countries by using the international calling card.

Currently, the credit card does not accept all the cards, but only uses a very limited card.

Lastly, the prepaid card type public phone card has magnetic tape attachment type and integrated circuit (IC) built-in type, but it can only be used in public phone which can read it.

As described above, in the conventional communication service, a fixed communication method for distinguishing subscribers using a line or a terminal number is used. However, in recent years, a credit call service that can provide a communication service without restriction of a terminal or a place appears. Was done.

The credit call service is a service that charges a call charge used after providing a communication service with security of a user's credit to a designated billing number.

Such credit call services have been developed in various forms, such as credit call services provided by the intelligent network, credit card public telephone services issued by credit cards or telecommunication operators, credit card public telephone services issued by operators, and calling cards issued by operators. In addition, there is an international credit call service using a credit card, and a prepaid card service that provides a communication service by paying a call in advance and using a payphone card as opposed to a credit call service that pays a post-paid call. have.

As described above, the credit call services provided in various forms have a problem in that the use procedures are different from each other, and there are limitations on the use terminal and the callable area.

In addition, there is another problem that the user is confused by using different numbers when subscribing to multiple credit call services and the service usage is very inconvenient, and a service provider has a separate system for providing various services. There was also a problem of inefficiency in terms of management.

In addition, the credit call service provided in various forms, such as the conventional intelligent network credit call service, credit call pay phone service, international credit call service and prepaid card service, causes confusion for communication users, and can use a specific terminal or call area when using the service. There are inconveniences such as limiting the number of services, and there is a burden to perform service management and system operation management for each service.

In order to solve the above problems, the present invention provides a service by a calling card holder or a foreign issued credit card holder issued by a foreign or other communication service provider when providing a service by integrating prepaid card services and credit call services similar to an intelligent network. Even if a request is made, the service can be provided after smoothly performing a credit inquiry through a network linkage between countries or telecommunications operators, and the billing for the provided services can be smoothly handled by the country or telecommunications service provider that issued the card. Its purpose is to.

A feature of the present invention for achieving the above object is that the calling party service switch (SSP) requests a call connection to the called party, sends a ring tone to the subscriber and waits for a response from the called party. Connecting the calling party to the calling party and storing the call start, calling and called number, card number, calling grade and call related information of the telephone type; and a local service control system (SCP) or credit card processing system. (CCPS), if necessary, reporting these information to the domestic service control system or the credit card processing system, and sending this information to the card issuer's service control system or credit card processing system. Informing the service control system or the credit card processing system as necessary, and the calling subscriber or incoming call. When the subscriber terminates the call, the called party stores additional call termination time in the stored information when connecting the service call so that it can be used to settle charges for service calls between countries after the call. Releasing resources, storing billing information for post-payment as needed, at a service exchanger or the home service control system or the credit card processing system, and calling the service control system or credit card processing system of the card issuing country. Report and store detailed billing information such as start time, call end time, caller ID, called party number, card type, card number, calling party grade, calling country and telephone type to the card issuer's service control system or credit card processing system, Report to your country's service control system or credit card processing system as needed. It lies in comprising the steps of: chapter.

Integrate card service and international calling card service into calling card service and unify credit card service using credit card public phone and credit card service for international credit call as credit card service. The low cost IC built-in pay phone card is used in the same way as the existing method, and only the expensive IC built pay phone card is used as a prepaid card service.

At the system level, an intelligent network is constructed as shown in FIG. 2, and the international credit call processing system described in FIG. 1C includes a service switching function (hereinafter referred to as SSF) and a service control function (hereinafter referred to as SCF). And the SCF execution part of the SCP described in FIG. 1A and the international credit call processing system described in FIG. 1C are integrated into SCP to accommodate a calling card service and a prepaid card service, and described in FIG. 1B. One CCPS adds intelligent network access to accommodate credit card services at home and abroad.

In addition, the SSF performing part of the international credit currency processing system described in FIG. 1C is unified to the SSP centering on the SSP described in FIG. 1A, and a network access function with CCPS is added.

On the other hand, communication among intercommunication carriers or countries has increased due to pluralization of communication operators, liberalization of overseas travel, and increased visits by foreigners, and the credit card and calling card can be easily accommodated by the communication demand and can be conveniently used by users. Communication service using.

In this case, in order to provide credit card and calling card service more efficiently, credit inquiry is performed quickly and accurately in the network linkage between telecommunication operators or countries, and service call is provided. The service provider needs to manage it.

Integrate the existing intelligent network credit calling service, calling card service in credit card public telephone and calling card service in international credit call into calling card service, and in existing credit card public telephone credit card service and international credit call Pluralization of telecommunications operators and countries when integrating credit card services into credit calling services to accommodate them in intelligent networks and providing services, and converting existing public phone cards into prepaid cards and accepting and providing them as prepaid card services in intelligent networks. With the increase of human exchanges, the importance of credit inquiry on calling cards and credit cards has increased, and the charges for service provision and post-payment settlement between countries / businesses have become more complicated.

Accordingly, when a calling card holder issued by a foreign or other carrier or a credit card holder issued by a foreign country requests service, the relevant DB of SCP or CCPS of the relevant country or service provider is searched on the card in a network interworking state between the country or carrier. The convenience of telecommunication users and operators was enhanced by inquiring credit for the service and allowing the service fee to be stored directly in the SCP or CCPS of the corresponding country or operator.

Each country's or carrier's currency is connected via gateway stations 14, 34, and 54, and common line signaling networks 8, 28, and 48 are connected by protocols specified between countries or carriers.

Calling cards and credit card holders issued by a country / business operator (hereafter referred to as telecommunications carriers) are provided with telecommunication services in the country of origin, from country to country, from country to country, from country to country There is a call from and a call from a country to a multinational.

The need for inter-country network interworking in such a currency type is when a communication service is requested from a country other than a cardholder or a card issuing country.

When a country requests service with a card issued by a country, the SSP (29) requests a credit check from SCP (26) or CCPS (27) of the country.

SCP (26) or CCPS (27) analyzes the credit card number requested by SSP (29), and if it is not a card issued by its own country, the address of SCP (6) or CCPS (7) of card issuing country is SSP ( 29).

SSP (29) re-requests credit inquiry to SCP (6) or CCPS (7) of each country by address notified by SCP (26) or CCPS (27) through common line signal network (28, 8) of both countries do.

The SCP (6) or CCPS (7) of the country analyzes the credit inquiry requested by the SSP (29) of the country by searching the relevant DB (1, 4) and analyzes the inquiry result. 28) to notify the home country SSP 29.

The SSP 29 of the country connects the service call requested by the user according to the credit inquiry result of the home country, and if the service call is an international call, the call path is connected through the gateway bureau 14, 34, 54.

After the completion of the service call, the SSP (29) notifies the card issuing country's SCP (6) or CCPS (7) of the card issuing country so that the card issuing country can process the fee for service provision. The service provision information is stored in the SSP 29 or notified to the SCP 26 or the CCPS 27 to be stored.

4 is a flowchart showing a service call processing procedure and a network interworking procedure between countries / businesses when integrating and providing pseudo credit call services in an intelligent network.

When the service user requests the credit call integrated service using the DTMF telephone, the end-station exchange (service originating exchange) notifies this to the SSP (S1).

The SSP identifies the service through the analysis of the requested service call and checks whether additional information is needed (S2).

After the inspection result determination (S3), the service can be provided, and if additional information is needed after determining whether additional information is needed (S4), the user requests additional information (S5), and the user additionally collects the information (S6) In addition to the additional information and checks whether the service is provided and whether the additional information is required (S7).

At this time, the SSP collects information on the calling subscriber number, the telephone type and the line grade from the service originating exchange and analyzes and inspects them together.

If the service is not provided in the service recognition and analysis verification (S2) or additional information analysis verification (S7), the user is notified that the service is not provided (S8), and the release process for the service sender is performed (S9). If the service can be provided (S3) and no additional information is required, the process goes to the credit inquiry step (S10).

The credit check shall be first performed by SCP or CCPS owned by the State / Operator (hereafter omitted by the carrier) at the request of the SSP.

SSP classifies the service into a calling card service SCP and the credit card service requests CCPS with the information collected from the service user or service originating exchange. Search and look up the credit status, and if the credit status is ineligible to provide the service to the service user after determining the inquiry result (S10) and informs that the service can not be provided (S21) and performs the release process for service transmission. (S22).

After determining the inquiry result (S11), the SCP or CCPS can use the credit inquiry result service, and determine whether the calling card and the credit card are other countries / other businesses (S12) to determine whether additional information is required for the credit inquiry if it is issued in Korea. (S13) If necessary, request to collect and notify additional information to the SSP (S14).

SSP sends an announcement requesting additional information to the service user according to the instructions of SCP or CCPS, collects additional information from the service users, and delivers it to SCP CCPS (S15).

If you can receive SCP or CCPS credit inquiry result (S11) service and determine whether the calling card and credit card are in another country / other carrier (S12) The SSP transfers the information necessary for the call processing to the called party requested by the service user (S23).

If calling card or credit card service is requested as a card issued by another country, SCP or CCPS analyzes the card number system to check whether there is an error and searches the service DB to obtain the address of SCP or CCPS of the card issuing country and notify the SSP. S10, 11, 12).

The SSP will re-inquire a credit check to the country using the address of the SCP or CCPS of another country received from its SCP or CCPS.

After determining whether the calling card and the credit card are other countries / other businesses (S12), and then the other country / subscriber, SCP or CCPS of the corresponding country searches the DB corresponding to the requested service and inquires the credit status (S16). After determining whether the result of the credit inquiry can provide the service to the service user (S17), if the result of the credit inquiry cannot provide the service to the service user, the user is informed that the service cannot be provided (S21). The release processing is performed (S22).

Determination of the inquiry result (S17) and the SCP or CCPS after the other country determines whether the credit inquiry result service is available and additional information is required for the credit inquiry (S18). If additional information on the credit inquiry is needed, additional information is collected by the SSP. Ask to be notified.

The SSP sends an additional information request announcement to the service user by the instruction of the SCP or CCPS of another country (S19), collects additional information from the service user, and delivers the additional information to the SCP or CCPS of the other country (S20).

After the credit check result determination (S17) of the SCP or CCPS of another country and the determination of the need for additional information (S18), the service can be provided and if the additional information is not necessary, the SSPS delivers the necessary information to the called party requested by the service user. do.

After the incoming processing information transmission (S23), the called exchange sends a ring to the called subscriber and sends a ring back tone to the calling subscriber (service user) (S24).

When the called subscriber responds (S25), the caller connects the calling party with the calling party and records the call start time for billing, and if necessary, the call connection information for the service call to the SCP or CCPS of the own country or another country. Report (S26).

When the calling subscriber or the called party terminates the call (S27), the SSP releases the call of the service call to the originating and called party.

When the call is released from the SCP, detailed billing information is reported to the card issuing country's SCP or CCPS so that the billing service for the service call can be processed by the card issuing country, and the service call information is sent to its own SSP for post settlement of service calls between countries. Report to SCP or CCPS for storage or storage in SCP or CCPS (S28).

FIG. 5 is a flowchart illustrating a procedure for connecting and releasing a call after receiving an incoming call and a charging process in a corresponding SSP of a service originating country or a telecommunications provider (hereinafter, a telecommunications provider) when providing an integrated credit call service in an intelligent network.

The calling SSP requests a call connection to the called party and sends a ring tone (ring, ring back tone) to the subscriber (ring notification (S24) in FIG. 4) and waits for a response from the called party (S31).

When the called subscriber responds (S32), the calling party connects the calling line with the called party, and stores information such as call start time, calling and called number, card number, calling grade and phone type (S33), and owns SCP or CCPS. If it is necessary to report (S34), the information is notified to the SCP or CCPS of the home country (S35), and also to the SCP or CCPS of the card issuing country as necessary (S36, S37).

When the calling party or the called party terminates the call (S38), the resources mobilized for connection are released (S39).

At this time, the SSP additionally stores the end time of the call in the stored information when the service call is connected, and can be used to settle charges for service calls between countries after the call.

The billing information for the post-payment may be stored in the SSP, and may be stored in the local SCP or CCPS as necessary (S40, S41).

And, the charge for receiving the service call using the card is processed in the card issuing country, so detailed billing information such as call number, card type and card number, call start and end time, caller grade and phone type, caller country, etc. Report to the card issuer SCP or CCPS to store (S42).

As described above, the communication service provider of the present invention can expect an increase in sales due to the increase in convenience of communication users and the increase in the number of users who can use the communication service, and facilitates billing processing for service provision and post-payment processing between countries or service providers. It will also contribute greatly to the rationalization of management.

In addition, the present invention may be applied to network interworking and billing processing when providing an intelligent network service such as an incoming billing service between countries or telecommunication operators.
