1 is a block diagram of a general intelligent network for carrying out the present invention.

2 is a flowchart illustrating an example of a process for providing an intelligent network service direct access call service according to an exemplary embodiment of the present invention.

The present invention relates to a method for controlling an outgoing call using an intelligent network, and more particularly, to a control method for faster card call service by accessing an intelligent network without dialing an intelligent network identification number.

In general, INTELLIGENT NETWORK is a telephone network design advocated by Bellcore, where service logic for calls is located separately from the switch facility so that services can be added or changed without having to redesign switch equipment. It means a network. The intelligent network is a structural concept that can be applied to all communication networks such as PSTN, Integrated Services Digital Network (ISDN), Public Land Mobile Network (PLMN), and is not limited to these network structures. It provides network capability to provide services independently from services and communication networks under a multi-vendor environment. In addition, the service implementation and the independence of the network implementation supported by the intelligent network enable service providers and equipment providers to independently define services and implement the network, thereby facilitating the introduction of new services on the basis of more flexibility and new capabilities. Let's do it.

Such an intelligent network provides various services to subscribers (SUBs). For example, free phone service, credit calling service, virtual private network service, single number service, and phone voting service ), A premium rate service, a personal number service, and a pass card calling service. Here, the card call service is a prepaid or postpaid card call service.

The prepaid card call service as described above purchases a prepaid or postpaid card issued by a main communication service provider such as Katie Co., Ltd., dials an intelligent network card call access identification number, and adjusts the card number and function according to the announcement provided by the intelligent network service provider. A button (eg, a "#" button), a password, and a called number are input to receive a call service with a desired counterpart. In this case, the currency charge is typically discounted by a separately agreed amount. Only the prepaid card is deducted from the precharged amount, and the postpaid card is announced in addition to the fee charged to the subscriber. Such call cards include KT Pass cards, World Phone Plus cards, etc., which are currently issued by Katie Co., Ltd.

In order to receive the card call service as described above, the user must first dial the intelligent network service request identification number (or card call identification number) (for example, 161) to access the intelligent network. After that, the card number, ?? button, and password set when registering the card in the SCP of the intelligent network and the called party number must be dialed consecutively. Therefore, in order to receive the card call service through the intelligent network, at least a card call identification number, a card number, a "#" button, a password, and the called party's incoming phone number have to be continuously input.

In order to solve this problem, conventionally, there was a method of making a card call by activating a card number with a subscriber's outgoing telephone number. That is, a method of processing a call charge by activating a card number registered in the intelligent network as the caller's phone number without entering the card number and password. This method is described in great detail in JP-A-2003-0042779 (published June 2, 2003, a prepaid card service that activates the card number by calling number).

However, the card call method disclosed in the above-mentioned patent does not only dial a card number and password registered in advance in the service database of the intelligent network, but in order to receive the card call service, it is inconvenient to dial the service access number for accessing the intelligent network. There was a ham. That is, the card call identification number " 161 " and the area code or mobile operator identification number " 011. 016, 017, 018, 019 " There was no efficiency by having to dial "XXX-XXXX" continuously.

Accordingly, an object of the present invention is to provide an intelligent network service direct access call control method for receiving an intelligent network card call service without inputting a card call identification number in an intelligent service.

Another object of the present invention is a hotline of a service switching system capable of matching telephone subscriber information to a card number stored in a service database of an intelligent network and transmitting dialing information to the intelligent network in response to a hook-off of the telephone subscriber (H0T). Provides intelligent network service direct access call control method to receive card call service without inputting prepaid card identification number (for example, "161" and "00721", etc.) to occupy hot line. Is in.

The present invention for achieving the above object is a local exchange (LO-EX: Local Exchange) for performing the call processing service of the subscriber, a service switching system (SSP: Service Switching Point), a signal relay (STP: Signal Transfer Point) and In the intelligent network service direct access call control method of an intelligent network system having a service control point (SCP), the intelligent network access to the subscriber information area of the local exchange and the card information area of the service database managed by the service control system. And a dialing tone in response to a hook off of the subscriber, and in response to the hooked-off subscriber being an intelligent network access subscriber. Occupies the hotline of the service switching system to transmit subscriber information to the service switching system. And requesting subscriber authentication by transmitting subscriber information transmitted from the service switching system to a service control system, and receiving a response number from the subscriber's actions upon receiving a response therefrom, thereby establishing a call path between the calling subscriber and the called subscriber. Characterized in that the process is formed.

As described above, the present invention sets intelligent network access information in a subscriber information area of a subscriber which is subscribed to a local exchange and is enabled to make a card call, and automatically according to whether the intelligent network access information is set or not, that is, a hotline of a service switching system. By occupying the card, it is possible to receive the card call service of the intelligent network without entering the prepaid card identification number "161" or "00721".

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings in which: FIG. It should be understood, however, that the present invention may be embodied in many different forms and should not be limited to the described embodiments. It should be noted that the embodiments of the present invention described below are intended to sufficiently convey the spirit of the present invention to those skilled in the art. It should also be noted that detailed descriptions of well-known functions and configurations in the art that may unnecessarily obscure the subject matter of the present invention are omitted.

1 is a block diagram of a general intelligent network for carrying out the present invention, wherein the intelligent network is a service control system (SCP) for creating and controlling services (hereinafter, referred to as 'SCP') 101, and plays an exchange role. Service Switching Point (hereinafter referred to as SSP) 102, and Intelligent Peripheral System (hereinafter referred to as IP) 103 in charge of resource provision. These components are integrated with the Integrated Service Digital Network Protocol (ISP) and Intelligent Network Application Protocol (INAP) through a Signaling Transfer Point (STP) 104. In this case, STP 104 is generally configured in a mesh form, and each component is connected to a signal repeater through two or more links for reliability. IP 103 connects SSP 102 and E1 trunks to bearer channel 108 and exchanges signaling messages with INSP protocol with SCP 101 and ISUP protocol with SSP 102 via signaling link 105 connected to STP 104. Provide processing and services. At this time, SCP 101 is provided with a service database (hereinafter referred to as "SDB") in which a plurality of Katie card information (hereinafter referred to as "card information") is stored. In the card information area in the SDB, subscriber information is recorded by inputting information of a terminal such as a user or a card sales consignment shop.

In the configuration of FIG. 1, reference numeral 107 denotes a local exchange (or local exchange) (LO-EX), and a plurality of subscribers are accommodated and provide call services by switching a call path between local subscribers. .

2 is a flowchart illustrating an example of a process for providing an intelligent network service direct access call service according to an exemplary embodiment of the present invention. In FIG. 2, i is an integer such as 1, 2, 3, etc., j is a natural number including 0.

First, in order for a subscriber subscribed to the local exchange 107 to make a card discount call provided by the intelligent network without dialing the card call identification number "161", the initial card call service must be registered. For example, after purchasing Katy Card for prepaid or postpaid payment, you must access the Kate Card Customer Center (ARS Center) and enter the Katy Card Number and Phone Number to subscribe to the intelligent network hotline service. The registration of users of the intelligent hotline service can be done as a subscriber telephone, but it can be registered by accessing SCP 101 of the intelligent network via the Internet. That is, when the telephone number and prepaid card number to use the card call service are input from the user to the SCP of the intelligent network through the Internet or a telephone, the SCP inputs the telephone number into the corresponding card area and the local exchange of the telephone number. Register the intelligent network hotline service by recording the INSR information in the subscriber information area of the network.

When registered as an intelligent network hotline service as described above, the subscriber's telephone number (telephone number used by the person who purchased the Katie card) for calling is registered in the corresponding card information area of the service database in SCP 101. The intelligent network service request (hereinafter referred to as "INSR") is registered in the corresponding subscriber information area in the local exchange 107 to which the AIS belongs. At this time, a subscriber registered with an INSR in the subscriber information area hooks off for transmission, and the local exchange 107 immediately enters the intelligent network service mode to perform the intelligent network service by occupying the hotline of the SSP 102 of the intelligent network. The detailed operation is as follows.

Now, if any of the subscribers of the plurality of subscribers 108 subscribed to the regional exchange 107 hooks off in step 50 of FIG. 2, the local exchange 107 detects this and recalls the dialing tone in step 52 of FIG. 3. Supply to the calling subscriber.

Thereafter, the local exchange 107 analyzes the subscriber information of the hooked-off subscriber in step 54 of FIG. 2 to search for an INSR capable subscriber. That is, it is searched whether the subscriber can make a card call.

If it is determined in step 54 that the calling subscriber is an INSR-capable subscriber, the local exchange 107 performs a normal call processing service in step 55 of FIG. In this case, the normal call processing service means that it is not a Katy card call service.

If it is determined in step 54 of FIG. 2 that the calling subscriber is an INSR capable subscriber, the local exchange 107 accesses the subscriber by occupying the hotline of the intelligent network in steps 56 and 58. That is, in step 58, the caller accesses the calling subscriber by occupying the hotline of the SSP 102 and transmits subscriber information of the calling subscriber to the SSP 102.

At this time, the subscriber information transmitted to the SSP 102 side includes an outgoing telephone number or a subscriber port number of the calling subscriber. By this operation, the calling subscriber is connected to the SSP 102 constituting the intelligent network only by hooking off the receiver.

Upon receiving subscriber information from the local exchange 107, SSP 102 sends the received subscriber information of the local exchange 107 to SCP 101 via STP 104. SCP 101 requests authentication from the SDB in step 60 of FIG. 2 to determine whether the subscriber can make a card call based on the received subscriber information.

Upon confirmation of the subscriber's card registration process 63, SCP 101 transmits card identification information (or card call unregistered subscriber information), i.e. authentication information (card call rejection information), to SSP 102 via STP 104 at step 64. At this time, the SSP 102 transmits call control information to the local exchange 107. In this case, the call control information is a message for validating or invalidating a dial digit transmitted from an originating subscriber.

The local exchange 107 receiving the call control information from the SSP 102 transmits an error message to the calling party in step 68 according to the call control information, or receives the called phone number transmitted from the calling subscriber in step 70 and receives the called number. Is transmitted to SSP 102.

Receiving the called number from the local exchange 107, the SSP 102 notifies the incoming call by transmitting a signaling to the SSPi + j side to which the called phone number belongs by a routing program. At this time, the SSPi + j notifies the incoming call by transmitting a ring tone to the called subscriber through the local exchange to which the SSPi + j belongs.

When the called party hooks off (an incoming call answering) in response to the call in the above state, the call is connected between the calling subscriber and the called party and the call is started.

As described above, the present invention registers the INSR information and the calling party information in each of the subscriber information area of the local exchange corresponding to the local subscriber registered in the intelligent network as the Katie card caller and the card information area of the service database of the intelligent network. When an INSR registered in the subscriber area of the user hooks off, it automatically occupies the SSP hotline and enters the intelligent network service mode, thereby immediately receiving a card call without dialing the intelligent network service identification number such as "161".
