Abstract

PURPOSE: A method for processing the short-distance routing between intelligent network providers in an exchange is provided to use the SCPs(Service Control Points) of intelligent network providers having their respective prefix systems so as to transfer their respective intelligent network services to their own service subscribers. CONSTITUTION: If a call is generated to the first subscriber exchange through a subscriber line from a subscriber terminal(200), the first subscriber exchange translates the prefix of the call(210). As a result of the translation of the prefix, if the intelligent network service to the second subscriber exchange is required, the first subscriber exchange transmits a calling number, a calling subscriber location identification number, and a called number to the first SCP connected to the first subscriber exchange(230). The first SCP replaces the calling number with the second subscriber exchange's prefix, to which the call is to be routed, and transmits the called number and the originating subscriber number, which are to be routed to the second subscriber exchange, to the first subscriber exchange(240). Based on the called number, the first subscriber exchange executes a call to the second subscriber exchange and transmits the newly formed calling number(250). If the call from the first subscriber exchange is executed, the second subscriber exchange translates the prefix of the call(300) and judges whether intelligent network service is required(310). If it is judged that intelligent network service is required, the second subscriber exchange transmits the called number and the calling number to the second SCP connected to the second subscriber exchange(320). Based on the numbers provided from the second subscriber exchange, the second SCP creates the telephone number of a called subscriber nearest to the calling subscriber and provides it to the second subscriber exchange(330). The second subscriber exchange terminates the call to the called number created from the second SCP and executes intelligent network service(340).

Description

METHODOLOGY FOR PROCESSING CALL ROUTING SERVICE BETWEEN DIFFERENTIAL INTELLIGENT NETWORK SYSTEMS}

The present invention relates to a method of processing short-range routing between intelligent network operators in an exchange. More specifically, the present invention relates to a method for smoothly receiving a call based on an intelligent network service between heterogeneous intelligent network providers linked to an SDX-200 exchange. A method for processing short-range routing between intelligent network providers.

Currently, there are various ways to provide phone number portability for handling Calls from calling party to specific number of called party. However, each exchange has its own hardware and software suitable for the unique purpose of exchange. In order to add new functions or to introduce services, it is disadvantageous in terms of cost and time since the hardware and software of the exchange must be changed to a considerable extent.

In view of this, separate parts responsible for various services in the exchange can be separated and implemented by general-purpose hardware and software to provide more efficient services while significantly reducing the time and cost required to design and implement new services. The next generation of Intelligent Network has been introduced.

The service processing structure of such a general intelligent network is made up of a service control system (SCP) and a plurality of service switching points.

In the case of an intelligent network operator known as Korea Telecom, which executes the services of the intelligent network, for example, a telephone number and a station number are set differently for each region, and a number policy that can distinguish regions by the station number is adopted. When the subscriber dials the intelligent network representative phone number of a specific company, for example, to order a product, the service changes the area according to the subscriber's calling number and connects the subscriber's calling party with the actual phone number of the company located in the nearest distance. Will be able to run.

On the other hand, in the case of other intelligent network operators known as 'Hanaro Telecom,' a situation in which a telephone station is not established for each region, but a wide range of regions are integrated and used as one station number. There is a system of assigning separate numbers and using the numbers to classify regions.

Therefore, for example, if a subscriber of Hanaro Telecom wants to order a product by calling a specific company subscribed to KT's intelligent network service, the station number of the originating subscriber of Hanaro Telecom indicates several regions, so it is actually in charge of KT's intelligent network processing. SCPs will not be able to correctly connect the call to the subscriber and to the nearest street vendor.

The present invention has been made in view of the above-described circumstances of the prior art, and between intelligent network operators in an exchange for delivering mutual intelligent network services to respective service subscribers using SCPs of heterogeneous intelligent network operators having different station numbers. The purpose is to provide a near-root routing method.

In order to achieve the above object, according to a preferred embodiment of the present invention, there is provided a method of executing an intelligent network service between a first subscriber exchange having a wide area number system and a second subscriber exchange having a local number system. It is determined whether an intelligent network service to the second subscriber exchange side is required for a call arriving at the first subscriber exchange, and if the call is determined to be an intelligent network service, the second subscriber exchanger to which the call is to be routed in the SCP associated with the first subscriber exchange. The calling party number and the original subscriber number to be routed to the second subscriber exchange are transmitted to the first subscriber exchange, and the first subscriber exchange is based on the called party number; In addition to performing the call, the caller ID formed by the SCP is transmitted, and the second subscriber exchange When the call from the first subscriber exchange is performed, the station number of the call is translated to determine whether it is an intelligent network service. If the intelligent network service is determined, the subscriber who made a call to the first subscriber exchange in the SCP associated with the second subscriber exchange is determined. In the exchange comprising the step of transmitting the called party number of the subscriber closest to the second subscriber exchange to set up the call, and performing the billing process for the subscriber who sets up the call of the intelligent network service in the first subscriber exchange A method for short-range routing between intelligent network providers is provided.

Preferably, the replacement of the calling number by the SCP linked to the first subscriber exchange searches for the corresponding station number managed by the second subscriber exchange using the calling subscriber location identification signal, and routes to the second subscriber exchange. Search for a called number to be called, and based on the search result, a pseudo calling number and a routing generated based on the first calling party number and the called station number and the called number found corresponding to the second subscriber exchange to the first subscriber exchange side And the called number for sending to the first subscriber exchange.

According to the method for short-range routing between intelligent network operators in an exchange according to the present invention, when the intelligent network service is executed between a first subscriber exchange having a wide area number system and a second subscriber exchange having a local number system. If the call arriving at the first subscriber exchange is related to the intelligent network service, the calling number is replaced from the SCP associated with the first subscriber exchange to the corresponding station number managed by the second subscriber exchange, and the calling number is transferred from the first subscriber exchange. When the forwarding number is delivered to the second subscriber exchange, the subscriber associated with the first subscriber exchange having generated the call and the subscriber number of the nearest subscriber are provided to the second subscriber exchange in the SCP associated with the second subscriber exchange. Therefore, an incoming call from the second subscriber exchange to the subscriber corresponding to the called number is received. It is such that air.

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

1 is a diagram illustrating a relationship between heterogeneous intelligent networks for explaining a short range routing processing method between intelligent network providers in an exchange according to the present invention.

In the figure, 10 denotes a first subscriber exchanger (for example, Hanaro Telecom) that accommodates a wide area number system, and 20 denotes a price set by a subscriber of the first subscriber exchange 10 in association with the first subscriber exchange 10. If it is necessary to transfer to the other intelligent network operator side, a calling position identification signal is formed based on the result of the analysis of the station number and the telephone number for the corresponding intelligent network operator side, and returned to the first subscriber exchange 10 side so that routing is performed. Represents an SCP.

In addition, 30 denotes a second subscriber exchanger (for example, Korea Telecom) in which a station number system is set for each region unlike the first subscriber exchanger 10, and 40 denotes the first subscriber exchanger introduced to the second subscriber exchanger 30 side. In response to a call setup request from (10), it indicates an SCP that allows a subscriber in a recently-dead area to connect a call.

A short distance routing control method between intelligent network operators in an exchange according to the present invention executed by the above configuration will be described in detail with reference to the flowchart shown in FIG.

First, when a call is generated from a subscriber station through the subscriber line 100 to the first subscriber exchange 10 side (step 200 of FIG. 2), the first subscriber exchange 10 translates the station number of the call requested by the subscriber terminal. (Step 210).

If the intelligent network service to the second subscriber exchange 30 is not needed as a result of the translation of the station number, call setting processing to the called party subscriber terminal accommodated in the first subscriber exchange 10 is executed. As a result, if an intelligent network service is required (YES in step 220 of FIG. 2), the first subscriber exchange 10 transmits the calling number, the calling party location identification number, and the called number to the SCP 20 (110 in FIG. 1). (Step 230).

Accordingly, the SCP 20 searches for the corresponding station number managed by the second subscriber exchange 30 by using the calling subscriber location identification signal, and searches for a called number to be routed to the second subscriber exchange 30. Done. In addition, the SCP 20 is a pseudo calling number generated based on the first calling party number and the station number and the called number found corresponding to the second subscriber switching unit 30 to the first subscriber exchange 10 side. And the called number for routing is transmitted to the first subscriber exchange 10 (120 of FIG. 1).

Then, the first subscriber exchange 10 transmits a call to the second subscriber exchange 30 using a called number provided to the SCP 20 and transmits a pseudo calling number (130 of FIG. 1). (Step 250 of FIG. 2).

The second subscriber exchange 30 performs the translation of the station number using the called number provided from the first subscriber exchange 10 (step 300 of FIG. 2). (YES at step 310 of FIG. 2) The called number and the calling number including the station number are transmitted to the SCP 40 (140 of FIG. 1) (step 320 of FIG. 2).

Then, the SCP 40 receives the called number of the subscriber of the region closest to the calling party subscriber of the first subscriber exchange 10 based on the called number and the calling number provided from the second subscriber exchange 30. It is generated and provided to the second particle exchanger 30 (150 of FIG. 1) (step 330 of FIG. 2).

Therefore, the second subscriber exchange 30 receives the call from the incoming number from the SCP 40 to perform the intelligent network service (step 340 of FIG. 2).

In addition, the first subscriber exchange 10 forms billing data using the number provided by the SCP 20 and subsequently uses the billing data with an intelligent network operator operating the second subscriber exchange 20.

As described above, according to the method for short range routing between intelligent network operators in an exchange according to the present invention, an intelligent network between providers having different number systems by simply adding a calling number replacement function to the SCP without any influence on the existing number system. You can run the service.
