The present invention relates to a number system for using a service and a network access method that a service user accesses to a network when integrated services of an intelligent network are provided to provide a credit call integrated service.

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. However, a credit call service that can provide 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 security of a user's credit.

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 public telephone, and an international credit call service using a calling card or credit card issued by a business 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 may cause confusion to users, and there are inconveniences of using a specific terminal or restricting a callable area. 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. A database (DB) 1, 2 for a subscriber of a credit call is built in a service control point (SCP) 4 to provide a service exchanger. When the SSP (Service Switching Point) 6 recognizes the credit call service call, it checks the credit to the service control system (SCP) 4 through the common line signaling network 5 and connects the call to the corresponding destination.

The structure of an intelligent network that can quickly and easily accommodate new and diverse services at the network level is defined as a service switch (SSP) (6), a service control system (SCP) (4), and a service management system (SMS). 3) and performs communication between the service switch (SSP) 6 and the service control system (SCP) 4 through the common line signaling network 5. The service switch (SSP) 6 is a switch that performs a gateway for interconnecting the existing telephone network and the intelligent network. The service call system requests the service control system (SCP) 4 through the common line signaling network 5 to connect the service call desired by the subscriber. Service control system (SCP) (4) is a DB system that holds the service control logic and subscriber data for intelligent network services. Upon receiving an inquiry about the intelligent network service call from the service switch (SSP) 6, information for call processing is transmitted to the service switch (SSP) 6 at the number of qualified tests and number translation for the call. The service management system (SMS) 3 is a system for managing a DB used by the service control system (SCP) 4, and operates and manages subscriber data necessary for service control, and statistics from the service control system (SCP) 4 It collects data and checks billing information, supports network management, and reports on service processing failures.

The intelligent network credit call service uses an electronic (DTMF) Dual Tone Multi Frequency (DTMF) telephone (including public telephones) and is entered by 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. 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.

1B is an intelligent network structure for a conventional credit card payphone service. Since a payphone for credit card automatically reads a calling card or a credit card, the user only needs to enter a password and a called number. This is a service that calls after sending information to search the DB.

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, 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 destination number in a 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) type, but can be projected only on 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-mentioned problems, the service system and the system are integrated, respectively, the prepaid card service, the calling card service and credit card service by unifying the numbering system and the use procedure for easy network access Its purpose is to provide a network approach.

In order to achieve the above object, the present invention provides a network access method of a credit call integrated service applied to an intelligent network, when receiving a service identification number and a card number, it is possible to identify a service by analyzing a service call and determine whether the service can be provided. Inspecting the first step; When the user inputs a service identification number, a second step of identifying a service through analysis of the service call and checking whether the service can be provided and whether additional information is needed; A third step of repeating the process of checking whether the service can be provided in the second step after collecting and requesting additional information from the user if the service can be provided and additional information is needed as a result of the check in the second step; And a fourth step of providing a credit call service according to the result of performing a credit inquiry when it is possible to provide the test result service of the first step or the test result service of the second step and the additional information is not necessary. Characterized in that comprises a.

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

2 is an exemplary diagram of an intelligent network structure for integrating a similar credit call service according to the present invention.

The present invention integrates an intelligent network credit call service, a credit card pay phone service, an international credit call service and a prepaid card service to an intelligent network that can easily accommodate a variety of new services. Integrate card service and international calling card service into calling card service, credit card service using credit card payphone and credit card service for international credit call unify with credit card service, magnetic tape attached pay phone card The low cost integrated circuit embedded pay phone card is used in the same way as the existing method, and only the expensive integrated circuit embedded pay phone card is used as a prepaid card service.

At the system level, the network is constructed as shown in Figure 2. Since the international credit call processing system 24 described in FIG. 1c performs a service switching function (SSF) and a service control function (SCR), the service control system described in FIG. The service exchange function (SCF) performing portions of the SCP) 4 and the international credit call processing system 24 are unified with the service control system (SCP) 46 to accommodate the calling card service and the prepaid card service. The credit card processing system 13 described in the above adds an intelligent network access portion to accommodate credit card services regardless of domestic and foreign. The service exchange function (SSF) performing part of the international credit call processing system 24 is centered around the service exchanger (SSP) 6 described in FIG. The network connection function with the card processing system 13 is added.

As such, calling and prepaid cards can emboss a card number on the front of the card, such as a credit card, to allow users to view and enter an embossed card number and automatically decrypt the card. Public pay phones allow you to use your service identification number and card (calling, credit and prepaid card) numbers without having to enter them yourself. In addition, calling cards, credit cards, and prepaid card services are used not only by Koreans but also by foreigners, so that a procedure for providing announcements in various languages has been added.

Specifically, the DB 41 for the calling card service stores the data necessary to provide a calling card service by integrating the calling card service of the existing intelligent network service, credit card public telephone service and the international calling card service of the international credit calling service. One DB.

The prepaid card service DB 42 is a DB that stores data necessary for providing a service by converting an existing integrated circuit built-in public telephone card into a prepaid card service, and the DB 43 for other services has been provided. DB that stores service data for wide area incoming billing service and information charge storage service.

U 44 for the credit card service is a DB that stores the credit card data necessary for integrating and providing the credit card service of the existing credit card public telephone service and the credit card service of the international credit calling service.

The service management system 45 is a system that manages the services managed by the service control system (SCP) 46 and the DBs 41, 42, and 43, and the service control system (SCP) 46 controls the existing credit call service. Service exchanger (SSP) using calling card service, prepaid card service that integrates calling card service of credit card public telephone and international credit call and DB (41, 42, 43) built by existing intelligent network service based on function It is a system that controls each service according to the request of 49).

The credit card processing system 47 is a system configured by integrating a function for an international credit call service in a credit card processing system for an existing credit card public telephone service and controls the service using the credit card DB 44.

The common line signaling network 48 provides a communication path between the service switch (SSP) 49 and the service control system (SCP) 49 and the credit card processing system 47, and the service switch (SSP) 49 Based on the existing service exchanger (SSP), the existing credit card public telephone service recognizes the service and integrates the function of the exchange system to query and answer the credit card processing system and the service exchange function (SSF) of the international credit call processing system. Applied service exchange system. The card payphone 51, the public payphone 52, the general phone 53, etc., which are electronic telephones (DTMF) telephones, are accommodated in the single station exchange 50. Route to (SSP) (49).

3a and 3b are explanatory diagrams showing the numbering system and the procedure for using the credit call integration service according to the present invention.

Figure 3a is an explanatory diagram showing the procedure for use in an electronic telephone including a public telephone which cannot automatically decipher the card, where the service identification number 61 is composed of three digits and numbered by calling, credit and prepaid card services. To assign a separate number (e.g., calling card '161', credit card '162', prepaid card '163').

Credit call services are used by foreigners as well as domestics, so it is necessary to provide announcements in various languages. Accordingly, the language selection number 62 can be selectively used. The language selection number 62 is composed of 1 digit, and when the language number (1: Korean, 2: English, 3: Japanese, 4: French, etc.) is input together with '#', the announcement is transmitted in the corresponding language. If omitted, the announcement will be broadcast in Korean. According to the announcement language selection, the announcement broadcast for the card number input in the corresponding language (63).

The card number 64 may be used from 7 to 19 digits, and should be entered with '#' if necessary. The calling card number shall consist of up to 19 characters in accordance with the International Organization for Standardization (ISO) 7812 and the International Telecommunication Uunion-Telecommunication Standardization Section (ITU-T) E.118 Recommendations to accommodate International Calling Card Validation (ICCV) services. The calling card number consists of two major industrial identifier numbers (assigned '89' for telecommunications), one to three digits for country code (eg, '82' in Korea), and telecommunication administration number (eg, Korea Telecom '1'). , A service identification code (e.g., credit call service '1', personal hospitality service '2', etc.), a billing number and a check digit.

When using a card issued in Korea, the billing number (currently 7 digits) can be entered and used.When entering all calling card numbers without distinction between domestic and international, the calling card number has a different length by issuing country. Therefore, enter the calling card number and '#' together. The credit card uses the existing 16 digits, and the prepaid card number is composed of 12 digits in order to efficiently manage the sales and service use of the card.

According to the user's language selection, when the announcement broadcast for the password input in the corresponding language (65), the four-digit password 66 is input. When using the prepaid card service, the password input guide broadcast 65 and the password input 66 may be omitted, and when using the credit card service, it may be omitted depending on circumstances.

Then, the called party number is input according to the announcement broadcast 67 for the called party number input, and in order to promptly perform the incoming call, '#' can be input together when the called party number is input (68).

3B is an explanatory diagram showing a procedure of use in a public telephone capable of automatically decrypting a card.

The public telephone automatically decrypts the card received from the user, and then transfers the three-digit service identification number 71 and the seven to nineteen-digit card number 72 to the network. At this time, the calling card is added with '#' as necessary as described in FIG. 3a and delivered together.

The language selection number 73 is composed of one digit, and when the language number and '#' are input together, the announcement is transmitted in the corresponding language, and when omitted, the announcement is transmitted in Korean. According to the user's language selection, when a guide broadcast for password input is transmitted in a corresponding language (74), a four-digit password is input (75). When using the prepaid card service, the password input guide broadcast 74 and the password 75 may be omitted, and when using the credit card service, it may be omitted depending on circumstances.

Then, the called party number is input according to the announcement broadcast 76 for the called party number input, and in order to promptly perform the incoming call, '#' can be input together when the called party number is input (77).

4 is a flowchart illustrating an embodiment of a network access method of a credit call integrated service according to the present invention, and shows a procedure of a user accessing a network and a service call processing procedure when integrating and providing a pseudo credit call service in an intelligent network.

In public telephones capable of automatically deciphering calling cards, credit cards and prepaid cards, when a user inserts a card into a public telephone, the public telephone decrypts the card and automatically converts the service identification number and card number into a single station exchange (service originating exchange). (81). If the user wants to specify the announcement language, the user inputs a language selection number (82).

The service originating exchange forwards these numbers to the service exchanger (SSP), which identifies the services and checks for service availability through analysis of the requested service call (83). At this time, the service exchanger (SSP) collects information on the calling subscriber number, telephone type and line grade from the service originating exchange and analyzes and inspects them together.

If it is impossible to provide the service as a result of the inspection (84), the user is notified that the service cannot be provided (the announcement of the tone or the language requested by the user) (85), and the release process for the service caller is performed (86). .

If it is determined that the service is available (84), the process proceeds to the credit check step (95).

Then, when the user enters the service identification number in the electronic telephone including the public telephone which cannot automatically decipher the card, the service originating exchange notifies the service switch (SSP) (87). In this case, when the user wants to designate the announcement broadcasting language, the user may input a language selection number, and the language selection number is also transmitted to the service switch (SSP) (88).

The service exchanger (SSP) identifies the service by analyzing the requested service call and checks whether the service is available and whether additional information is needed (89). If service is available (90) and additional information is required (91), the user is asked for additional information (card number) in the language requested by the user (92) and the user enters additional information (93) Along with the information, it is checked whether the service is provided and whether additional information is needed (94). At this time, the service switch (SSP) collects information on the calling subscriber number, telephone type and line grade from the service originating exchange, and analyzes and inspects them together.

If the service is not available in the service recognition and analysis verification (89) or the additional information analysis verification (94) (90), the user is notified of the service unavailable by tone or a guide broadcast in the language requested by the user (85). If the service is released (86) and service is available (90) and no additional information is required (91), the process proceeds to the credit check step (95).

The credit check is performed by the service control system (SCP) or credit card processing system at the request of a service exchanger (SSP) (95), and if the credit check result is unable to provide the service to the service user (96). It informs that the service cannot be provided (106) and performs the release processing for service origination (107).

The service control system (SCP) requests the service exchanger (SSP) to collect and notify additional information if the credit check result service is available (96) and if the credit check requires additional information (97). The additional information may be a password and a called number, the password may be required in the calling card service, depending on the situation in the credit card service, but not in the prepaid card service. In addition, when the called number is registered and used as a speed dial or when the call is restricted (called call number designation, called area restriction, etc.), the called number (shortened number) is required when the credit is checked by the service control system (SCP). The service switcher (SSP) transmits an additional information request announcement broadcast to the service user according to the instruction of the service control system (SCP) (98) and collects additional information from the service user and transmits the additional information to the service control system (SCP) (99). ).

If the credit check result of the service control system (SCP) can be provided (96) and no additional information is required (97), the service exchanger (SSP) forwards the information necessary for the incoming processing to the destination exchange requested by the service user ( 100). The called exchange sends a ring signal to the called subscriber and sends a ring back tone to the calling subscriber (service user) (101). When the called subscriber answers (102), the SSP connects the calling party and the called party's call path and records the call start time for charging, and if necessary, the service switching system (SCP) or credit card processing system. The call connection information for the service call is reported (103). And, when the calling or terminating subscriber terminates the call (104), the service switchboard (SSP) performs the call release of the service call to the calling / receiving subscriber and stores the charging information on the service call, and controls the service as necessary. The system (SCP) or credit card processing system is notified of the end of the call (105).

As described above, the present invention provides a credit call service provided by an intelligent network, a credit card pay phone service by a calling card or a credit card holder using a credit card pay phone, an international credit call service using a calling card or a credit card issued by an operator, and the like. User's network is easily integrated by unifying the numbering system, service usage procedure and method for calling card, credit card and prepaid card service when integrating similar services with prepaid card service using public telephone card. The service is available to all electronic telephones, including public telephones, to increase the convenience of communication users, and to make announcements available in various languages so that foreigners can easily use the service. Your carrier is on your side It can be expected to increase due to expansion of sales and increased coverage and the number of people.
