The present invention relates to an interworking method between a current generation intelligent network service provided by an intelligent network service exchanger and a card call service, and more particularly, a card call service provided with a current generation intelligent network service by interworking a current generation intelligent network service with an existing card calling service. It relates to a technology that can be used.

With the development of communication technology and the changing environment of the communication market, it is possible to use more convenient and various services selectively.In order to overcome the limitations of the existing general telephone network and to expand the area of providing competitive new services, the intelligent network (Intelligent Networlk: We started to provide intelligent, personalized and advanced services using IN.

In other words, the intelligent network service is a high-level communication network service that efficiently implements and operates various communication services by installing a separate large computer and database on an existing communication network.

1 is a conventional current generation intelligent network configuration, a service control system (Service Contol Point: SCP) (10) for controlling the intelligent network service with information necessary to perform the service provided by the intelligent network;

Transmitting signaling messages to other nodes A signaling relay exchange that performs a large-capacity signal relaying process as a packet exchange that transmits and receives signaling messages. Signaling transfer point (STP), which is a basic switching node constituting a signaling network (STP) 30a to 30d )Wow;

A signal exchange does not occur on the same path as data transmission, and a separate digital channel called a signal link is created, where there is an out-of-band signal processing where messages are exchanged between network elements at speeds of 56 to 64 Kbps. Service Switching Point (SSP) 100a-100b; And

It consists of a user terminal (eg, a telephone, etc.) 50a to 50d requesting a service provided by an intelligent network through a single station exchange 40a to 40d.

In the intelligent network service, when the user requests a service through the terminal exchanges 40a to 40d, the service exchanger 100a to 100b requests the service from the service control system 10 through the signal relay exchanges 30a to 30d. Receive information and control necessary to perform service and provide it to users.

The intelligent network services provided by the intelligent network having such a structure include card calling (aka KT-Card) service, personal number (PN) service (eg 0502-XXX-XXXX), and information storage agency (Premium). Rate Service (PR) service (eg 700-XXXX), Phone Voting (PV) service (eg 1580-XX), National Number Service (SN) service (eg 1588-XXXX), Emergency response service and free phone service.

The card call service is a service for making calls using a card anywhere at home and abroad, and has functions such as limiting a call from a foreign country to a foreign country (HCB), limiting a maximum call within a time limit, and re-entering a password.

The lifetime number service is a service that allows a call to be made regardless of the location of the called party by assigning a personal number to the service subscriber instead of giving a telephone number around the existing line.

The information charge storage agent service is a service for providing information services desired by the user, such as various life information, guide information, product introduction of the company.

The telephone voting service is a service that provides a real time to the subscriber by advertising a virtual number, and aggregates and analyzes the contents of questions and answers from viewers or readers.

The emergency response service is a service that the network handles the routing according to the emergency as quickly as possible, and the toll-free service provides a special number (080) and a virtual number (XXX-XXXX), and the call charge of the incoming call to this number is the caller. The service is charged to the called party instead of (service user).

FIG. 2 is a flowchart illustrating a conventional card service call processing process in FIG. 1. The service exchangers 100a to 100b illustrate a call interworking process between a card call service and another service provided by the intelligent network.

First, when the user terminal 50a to 50d receives an intelligent network identification number "161" through a card call service call attempt (S2), the service switcher 100a to 100b receives a card call from among the registered intelligent network service identification numbers. Recognizing it as a service, it connects the announcement broadcast channel assigned in the relay call processing block of the service switch (100a ~ 100b) and transmits the card number input announcement to the user terminal (50a ~ 50d) (S4).

When the card number is input from the user terminals 50a to 50d, the announcement broadcast channel is released and the received number (digit) is stored in a buffer. When the last number (digit) of the card number is input, the service switch 100a to The received card number is transmitted to the service control system 10 according to a predefined primitive for providing the intelligent network service between the service control system 100b and the service control system 10 (S6).

The primitive is a basic operation element exchanged between protocol layers. The primitive forms a message as a primitive itself or a set, and generates an operation for exchanging information between intelligent network elements.

Accordingly, the service control system 10 and the service exchanger 100a to 100b communicate with each other by exchanging these primitives. The types of primitives include a service exchanger 100a for a qualification check of an intelligent network service call, translation of a number, and verification of a call. ˜100b), PROVIDE, PROMPT, and GAP for notifying the service switcher 100a to 100b as a result of performing the qualification check and the number translation of the intelligent network service call.

The service control system 10 receives a primitive including a password input guide broadcast code requesting a password input for the received card number from the service control system 10 and transmits the password to the corresponding broadcast channel to the user terminals 50a to 50d. The announcement broadcasts (S8).

Receiving a password for the card number from the user terminal (50a ~ 50a) and sends a primitive containing the password information to the service control system 10 (S10).

When the authentication of the previously received card number is performed using the password information received by the service control system 10, and the authentication is permitted, the user terminal receives the primitive including the called party number request information. 50a to 50d) transmits the called party number guide announcement (S12).

The card call service user transmits an intelligent network service number, rather than a general subscriber number, to a service exchanger 100a to 100b as the called number through the user terminals 50a to 50d, and the service exchanger 100a to 100b receives the received call. The number (intelligent network service number) is transmitted to the service control system 10 (S14).

Since the intelligent network service logic for the intelligent network service number requested as the called number is not activated, the service control system 10 receives a primitive for terminating the card call service (S18).

The service call release procedure for the user terminals 50a to 50d is performed according to the received primitive information (S20), and the call termination announcement (or tone) for switching off and ending the call to the user terminals 50a to 50d. To send (S22).

That is, when the card call service inputs a service number other than the card call service provided by the intelligent network service as the called number in the service execution procedure, the card call service does not exist because the interworking logic between the card call service and other intelligent network services does not exist. Le has a disadvantage that can not be provided.

Accordingly, the present invention provides an intelligent network service using a card call service that provides a service according to a corresponding intelligent network service logic by interworking with an intelligent network service and a card call service required by a user in the course of a card call service. The purpose is to provide a method.

In the intelligent network service using method using a card call service to achieve the above object, in the intelligent network consisting of a service control unit and a service exchange unit, the service exchange unit provides an intelligent network service using a card call service, the card from the user terminal A first step of performing, by the service exchange unit, a user authentication by receiving the authentication number corresponding to the card number and the card number of the user from the user terminal when a call service call is attempted; A second process of transmitting an intelligent network service number for the intelligent network service to the service controller when a predetermined intelligent network service is requested from the user authenticated through the user authentication; The service control unit receiving the intelligent network service number may include a third process of providing the intelligent network service through the service exchanger by driving the intelligent network service logic corresponding to the intelligent network service number.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the intelligent network service interworking using the card call service according to the present invention is applied to the conventional intelligent network shown in FIG. 1, and is performed by the service switchers 100a to 100b of FIG. 1 and uses an intelligent network using a card call service. Service interworking will be described with reference to FIGS. 3A-3B.

In addition, a card used when using the above service includes a TK-Card, and the card described below may be referred to as a KT-Card.

3A to 3B are flowcharts illustrating a process of interworking call processing between a card call service and an intelligent network service according to the present invention in FIG. 1, and a process of providing another intelligent network service through a card call service at a service switcher 100a to 100b. Indicates.

First, the user terminal 50a to 50d receives an "161" number which is an intelligent network identification number through a card call service call attempt (S102).

The service exchanger 100a to 100b recognizes the card call service among the registered intelligent network service identification numbers to drive the card call service logic, and connects the announcement broadcast channel allocated in the relay call processing block of the service exchange 100a to 100b. The card number input guide broadcast is transmitted to the user terminals 50a to 50d (S104).                     

When the card number is input from the user terminals 50a to 50d, the announcement broadcast channel is released and the received number (digit) is stored in a buffer. When the last number (digit) of the card number is input, the service switch 100a to The received card number is transmitted to the service control system 10 according to a predefined primitive for providing an intelligent network service between 100b) and the service control system 10 (S106).

The service control system 10 receives a primitive including a password input guide broadcast code requesting a password input for the received card number from the service control system 10 and transmits the password to the corresponding broadcast channel to the user terminals 50a to 50d. The announcement broadcasts (S108).

The user terminal 50a to 50a receives the password for the card number and transmits a primitive including the password information to the service control system 10 (S110).

When the authentication of the previously received card number is performed using the password information received by the service control system 10, and the authentication is permitted, the user terminal receives the primitive including the called party number request information. 50a to 50d) transmits the called party number guide announcement (S112).

The card call service user selects a desired intelligent network service among a lifetime number service, an information charge receiving service, a telephone voting service, and a national representative number service, and provides a service number corresponding to the intelligent network service selected as the called number. 50a to 50d) to the service exchange 100a to 100b.                     

The received intelligent network service number, which is the called party number, is loaded on the corresponding primitive and transmitted to the service control system 10 (S114).

The service control system 10 drives the intelligent network service logic of the service control system corresponding to the received intelligent network service number, and transmits the intelligent network service numbers to the service switchers 100a to 100b (S116).

The service switcher 100a to 100b recognizes that the intelligent network service number received through the intelligent network number translation procedure is a request for requesting an intelligent network service other than the currently running card call service (S118), and corresponds to the received intelligent network service number. The type of intelligent network service is determined (S120).

As a result of the determination, if the requested intelligent network service type is a lifetime number service, a lifetime number service logic is driven (S122), and the service control system 10 transmits a primitive including the lifetime number service number (S124).

The service control system 10 receives the actual called party number information corresponding to the corresponding intelligent network service number according to the lifetime number service logic (S126).

When it is determined that the outgoing call is re-translated by using the received called party number, the incoming number is occupied by the relay line, and the called number is transmitted to the counterpart of the service switcher 100a to 100b of the corresponding called number (S128).

Receiving the status information of the called number from the large station, when the subscriber of the called number responds successfully call processing proceeds and a call is made between the caller of the card call service and the subscriber of the called number (S130).

If the call is successful, the service interworking information including the subscriber information and the status information of the called number is separated into the card call service logic and the newly driven lifetime number service logic and transmitted to the service control system 10 (S132). ).

The charge for the card call service call and the charge for providing the lifetime number service are started (S134), and when the call ends, the charge for the card call service and the charge for providing the lifetime number service are recorded (S136), The card call service call and the lifetime number service call are released normally (S138).

If the type of the intelligent network service corresponding to the incoming request intelligent network service number in S120 is the information charge storage agent service or the national representative number service, the corresponding service logic is driven (S140 and S142), and the corresponding service is controlled by the service control system 10. The primitive including the number is transmitted (S124), and the processes of S126 to S138 are performed.

However, in the case of providing the announcement information, in step S126 receives the announcement information from the service control system 10, and provides the status of the announcement service service to the card call service subscriber of the caller.

Further, if the type of the intelligent network service corresponding to the incoming request intelligent network service number in S120 is a telephone voting service, the telephone voting service logic is driven (S144), and the service control system 10 sends a primitive including a telephone voting service number. It transmits (S146).

The voting guidance broadcast corresponding to the telephone voting service number is transmitted to the card call service user terminals 50a to 50d, and the voting result is input from the user terminals 50a to 50d (S148).

The charging for the card call service call and the charging for providing the telephone voting service are started (S150), and the telephone voting service call is released (S152).

After recording the charge for the card call service and the provision of the telephone voting service, the charge is ended (S154), and the card call service call is ended (S156).

As described above, according to the present invention, by providing the card call service and other intelligent network services in the service exchanger, it is possible to receive a variety of intelligent network services through the card call service to improve the satisfaction of the service, the utilization rate of the card call service And improving the completion rate.
