Charging Method for Credit Call Integration 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 level of living and the range of social activities have expanded. According to these social changes and users' needs, new communication systems and communication networks have emerged, and various communication services can be provided using them.

Currently, credit call services, which provide communication services based on the credit of users or subscribers, have appeared in various forms in terms of technology or business. Figure 1a is a credit call service developed in the intelligent network structure to establish a database (data base, abbreviated as DB) in the service control system (Service Control Point, abbreviated as SCP) service exchange ( Recognizing a credit call service at Service Switching Point (abbreviated as SSP), a credit inquiry is made to SCP through a common line preference network and the call is connected to the destination. The intelligent network credit call service uses an electronic Dual Tone Multifrequcy 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. Enter the password and the called number can be entered according to the announcement. At this time, charging information for service provision is stored in 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.

1B is a network diagram for a credit card payphone service. The payphone for credit card automatically reads the calling card credit card, so the user simply enters the password and called number and sends the information to the credit card processing system (hereinafter referred to as CCPS) to search the DB. After call service, the billing information for service provision is managed by CCPS.

This service can be used only in credit card payphones, and since CCPS is accessed through public data networks (Public, Switched Data Network, hereinafter referred to as PSDN), there is a problem in that it is difficult to expand the service.

Figure 1c is a network diagram for providing an international credit call service. It is an international credit call service using an international calling card or a bank credit card issued by a telecommunications company. It provides a service using an international credit call processing system. In DTMF phones including payphones, if you enter 4 digit service identification number, 16 digit card number, 4 digit password and called number, you can call the DB after searching the DB by searching the DB in the international credit call processing system. For example, the billing information for service provision is managed by the international credit call processing system, and when used in public telephones, coins or a telephone card are required in the same way as the intelligent credit call service. This service also requires the user to enter all the 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. Credit cards do not accept all cards, but use very limited cards. Lastly, the public telephone card, which is a prepaid card type, has a magnetic tape attachment type and an integrated circuit (IC) built-in type, but can be used only in a public phone that can read it.

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 specified charge number to a call charge used after providing a communication service with the credit of a user. Such credit currency services have developed in various forms. There are 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 using credit card public telephones, and international credit call services using calling cards or credit cards issued by business operators. Contrary to the credit call service, which pays a post-paid fee, there is a Sun Card Card service that pays for the call in advance and provides communication service for the amount paid using a card payphone.

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 number is confused and the service is very inconvenient by being given a different number when subscribing to several credit call services. In addition, there is a problem that a communication service provider is inefficient in terms of operation management because there is a separate system for providing various services.

In addition, conventionally, credit call services provided in various forms, such as intelligent network credit call service, credit card public telephone service, international credit call service and prepaid card service, cause confusion to communication users, and can use a specific terminal or call when using the service. There are inconveniences such as limiting the area, 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 subscriber 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 the credit check is smoothly performed through the interworking between the countries or the telecommunications operators, and the billing for the provided services can be handled by the country or the 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 requests a call connection to the called party and sends out a ring tone to the subscriber and waits for a response from the called party. Connecting the network and storing the incoming / outgoing information, notifying the home service control system or the credit card processing system if it needs to be reported to the home service control system or the credit card processing system, and the calling subscriber or the incoming call. When the subscriber terminates the call, releasing the resources mobilized in the incoming / outgoing call; storing the billing information for the post-payment as necessary at the service switchboard, the home service, the control system, or the credit card processing system; Detailed billing information by the card issuer's service control system or credit card processing system Report lies in comprising the step of storing.

At the system level, the intelligent network is configured as shown in FIG. 2. Since the international credit call processing system described in FIG. 1C performs a service switching function (hereinafter referred to as SSF) and a service control function (hereinafter referred to as SCF), the SCP described with reference to FIG. The SCF execution part of the international credit currency processing system described in 1c is unified with SCP to accommodate calling card service and prepaid card service, and CCPS described in FIG. do. Then, the SSF execution 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. Communication between telcos and countries has increased due to the pluralization of telcos, liberalization of overseas travel, and the expansion of visits by foreigners. It is a service. In order to provide credit and calling card services more efficiently, service calls can be provided by quickly and accurately performing credit inquiry in the interworking between telecommunication operators or nations, and billing for the provided services is provided in each country or communication that issued the card. The operator needs to manage it.

Integrate 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 use credit card service in existing credit card public telephone and international credit call Integrating credit card services into credit calling services to accommodate them in an intelligent network and providing services, and converting existing public phone cards into prepaid cards and accepting and providing them as prepaid card services in an intelligent network. The expansion of human exchange has increased the importance of credit checks on calling cards and credit cards, making the charges for service provision and post-commission billing between countries / businesses 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 services, the relevant DB of the relevant country or carrier's SCP or CCPS is searched on the card in the network interworking state between the country or the 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.

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

3 illustrates a network interworking structure between a country and a communication service provider for a calling card and a credit card service when integrating and providing a similar credit call service in an intelligent network. The currency of each country or service provider is connected through gateway stations (4, 34, 54), and the common line signaling network (8, 28, 48) is connected by protocols defined between countries or service providers. Calling cards and credit card holders issued by a country / business operator (hereinafter referred to as telecommunication carriers) are provided with communication services in a country, currency from country to country, country to country, country to country There is a call from and a call from a country to a multinational. In such a conundrum, inter-country network interworking is required when the cardholder requests communication service from the country of origin, not from the card issuing country. When a country requests service with a card issued by a country, the SSP (29) requests credit inquiry to 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 the country by address notified by SCP (26) or CCPS (27) through the common line signaling network (28, 8) of both countries. do. The CCPS (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 SSP 29. The SSP 29 of the country connects the service call requested by the user according to the result of the credit inquiry 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 providing information is stored in the SSP 29 or notified to the SCP 26 or the CCPS 27 to be stored.

4 is a flowchart illustrating a service call processing procedure and a network interworking procedure between countries / businesses when integrating and providing similar credit call services in an intelligent network. When the service user requests a credit call integration service using a 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 the service is available and whether additional information is needed (S2). If it is possible to provide a test result service (S3) and additional information is required (S4), request additional information from the user (S5), collect additional information input by the user (S6) whether to provide a service with additional information and Examine the need for additional information (S7). At this time, SSP collects information on calling subscriber number, telephone type and line grade from service calling exchange and analyzes and checks them together. If service recognition is not possible in service recognition and analysis verification (S2) or additional information analysis verification (S7) (S3), the user is notified of the service provision failure (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 (S4), the process goes to the credit inquiry step (S10).

The credit inquiry shall be first performed at SCP or CCPS owned by the State / Operator (hereafter omitted by the carrier) at the request of the SSP. SSP categorizes service, calling card service is SCP and credit card service is CCPS. When requesting credit inquiry about service provision along with information collected from service user or service originating exchange, SCP and CCPS of the country are service DB. Search the credit status by searching (S10), if the result of the credit inquiry can not provide the service to the service user (S11) informs that the service can not be provided (S21) and performs the release processing for service transmission (S22). SCP or CCPS can use the credit inquiry result service (S11) and if calling card and credit card or domestic issue (S12) if credit inquiry requires additional information (S13), SSP will collect and notify additional information. request. The SSP sends an announcement requesting additional information to the service user by the instruction of the SCP or CCPS (S14), collects additional information from the service user, and delivers the additional information to the SCP or CCPS (S15). If the service can be provided as a result of the credit check of SCP or CCPS (S11) and issuing card (S12) and no additional information is needed (S13), the SSP delivers the information necessary for the call processing to the called party requested by the service user (S23). ).

When calling card or credit card service is requested by card issued by other country, SCP or CCPS analyzes the card number system and checks the abnormality, searches the service DB and obtains the address of SCP or CCPS of card issuing country and informs SSP. (S10,11,12). The SSP will refer the credit to the country again using the address of the SCP or CCPS of the other country from its own SCP or CCPS. SCP or CCPS of the corresponding country searches the DB corresponding to the requested service and inquires the credit status (S16) .If the credit inquiry result cannot provide the service to the service user (S17), the service cannot be provided. It guides (S21) and performs the release process for service transmission (S22). SCP or CCPS of another country is requested to collect and notify additional information to SSP if the credit inquiry result service is available (S17) and if the credit inquiry requires additional information (S18). 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). If the service can be provided as a result of the credit inquiry of the SCP or CCPS of another country (S17) and no additional information is required (S18), the SSP delivers the information necessary for the call processing to the called party requested by the service user (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 party answers, the SSP connects the calling party and the calling party's call path and records the call start time for charging, and if necessary, sends the call connection information of the service call to the SCP or CCPS of the own country or another country. Report (S26). When the calling subscriber or the called subscriber terminates the call (S27), the SSP releases the call of the service call to the called subscriber. When the call is released from SCP, detailed charging information is reported to SCP or CCPS of the card issuing country so that the card issuer can handle the charge for the service call, and the service call information is stored in its own SSP for post settlement of service calls between countries. Or report to SCP or CCPS so that it can be stored in its own 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 communication service provider (hereinafter, a communication service 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 (incoming call notification (S24) in FIG. 4) and waits for a response from the called party (S31). When the called party responds (S32), the caller connects the calling line with the called party and stores information such as call start time, calling and called number, card number, rating, and phone type (S33), and sends it to the local SCP or CCPS. If there is a need to report (S34), this information is notified to the SCP or CCPS of the country (S35), and to the SCP or the Chechenen of the card issuer 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 fee settlement may be stored in the SSP, or may be stored in the local SSP or CCPS as necessary (S40, S41). And the billing for the service provided by 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 and save to SCP or CCPS of card issuing country. (S42)

As described above, the present invention can expect an increase in sales due to an increase in the convenience of a communication user and an increase in the number of communication users, and facilitates post-payment processing between countries or service providers for billing processing. It will also contribute greatly to the rationalization of management. In addition, the present invention can be applied to the network and the charging process in the case of providing the intelligent network services, such as incoming billing services between countries or telecommunication operators.
