Abstract

PURPOSE: A method for informing a number change is provided to deliver an announcement relating to a local or a long-distance call to an originating terminal, when an originating subscriber of a network requests a call connection with a subscriber who moves to a specific area of the network, and to select the attempted call. CONSTITUTION: If a receiving terminal is registered in an announcement service and if an existing local number is not equal to a changed local number, a service control point system(SCP) transmits a number portability announcement delivering command to an intelligent peripheral(IP), and simultaneously transmits an establish telephony connection(ETC) command to a service switching point(SSP), then transmits a play announce report(PA) command to the IP. The SSP controls an ETC speech path to be connected. The IP connects a speech path of the SSP, and delivers an announcement relating to a number portability to an originating terminal, then transmits a digit signal corresponding to the announcement received from the originating terminal to the SCP. The SCP transmits a call connection command for connecting a call between the receiving terminal and the originating terminal to the SSP, and transmits a disconnect forward connection(DFC) command and a release(REL) command to the SSP. The SSP controls the receiving/the originating terminals to be connected with the call, and disconnects the number portability announcement in the originating terminal according to the DFC command, then completes an intelligent network processing procedure according to the REL command. The SSP controls a general call processing procedure to be performed.

Description

Service Method for Number Porting in Intelligent Network Switch {METHOD FOR SERVING NUMBER MOVEMENT RESPONSE IN A INTELLGENT NETWORK EXCHANGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent network exchange (hereinafter, abbreviated as INX). In particular, after a subscriber who has subscribed to a number porting service moves to a specific area of the network, the subscriber is subscribed to the number porting service. When a subscriber requests a call connection, the present invention relates to a number transfer guide service method in INX, which allows a user to select whether or not to attempt a call by transmitting a guide broadcast for a local or long distance call to the calling terminal.

In general, INX is a switch interspersed in a telecommunication network, and a transport layer and network elements in a transport layer that actually exchange and transmit communication information such as data around an intelligent service switching point. Service control point system that performs the actual control and management through the request for the intelligent network service generated in the signal layer and the transport layer centered on the signal transfer point for transmitting control signals Conceptually, such as the central service layer, these three types of layers are collectively organized.

Therefore, the intelligent network service is possible when the above-listed layers are comprehensively configured and their functions are organically related. The main reason for separating the transport layer and the service layer is to minimize the effects of the change at each node. Adapt to service introduction or subscriber needs.

In addition, as a characteristic of the intelligent network service, by using a virtual number that is not directly related to actual routing as a subscriber number, the same virtual number is commonly used anywhere in the country regardless of region. Flexibility in the selection of the called party is required, and various types of billing can be provided according to the type of service, which can benefit both calling and receiving subscribers. The subscriber can directly control the matters related to routing and restriction of the service call and select and use additional functions for each subscriber.

In addition, the types of intelligent network services include incoming billing, credit calls, virtual private networks, unique numbers, telephone polls, emergency calls, conference calls, voice mail, e-mails, call destinations, information charge service, and free listening to commercials. Calls, etc. Detailed features include national representative number, local routing number, temporary routing, outgoing restrictions, data change, call distribution, call transfer, call waiting, call blocking, special routing, voice announcement, call prompting, billing distribution. , Additional charges, multiple personal identification numbers, consecutive calls, speed dials, voice recognition, voice synthesis, usage history information measurement, temporary charge change, mass centralized call provision services, and the like.

As described above, among the various types and detailed functions of the intelligent network service, the number porting guide service in the conventional INS transfers the network to the subscribers subscribed to the number porting service after the subscribers who have subscribed to the number porting service move to a specific area of the network. When the subscriber attempts to connect the call, it immediately controls the call path between the calling party and the called party. Therefore, even in the case of a specific area in the network, i.e., a long distance call, it is not possible to select whether or not to connect the call, so there is a billing dispute for the corresponding call, there is no financial choice, and there is an economic loss, and the quality of service is improved. There was an inefficient problem in the subscriber acquisition competition.

Accordingly, the present invention has been made to solve the above-mentioned problems, the object of the present invention is that subscribers who have subscribed to the number porting service move to a specific area in the network, and then the subscribers who have subscribed to the number porting service call the subscribers in the network. When requesting a connection, the present invention provides a method for providing a number porting service in INX that allows a user to select whether or not a call is attempted by transmitting a guide broadcast on a local or long distance call to the calling terminal.

In the present invention for achieving this purpose, the number porting guide service method in the INX is a legitimate subscriber through the profile authentication procedure of the destination terminal as the intelligent network service processing unit transmits the intelligent network service processing request message to the service control system unit. Transmitting a device unit connection instruction command to an intelligent network service performing unit; Transmitting, by the intelligent network service performing unit, a setup request operation to the service adding device unit, and the service adding device unit transmitting a setup response operation corresponding to the bearer channel setting to the intelligent network service performing unit; If the destination terminal is registered in the number port guide service in the intelligent network service performing unit, and the existing area code and the changed area code is not the same, transmitting a number port guide broadcast transmission command to the service additional device unit; Connecting a call path from the service adding device unit to the intelligent network service performing unit, and transmitting a guide broadcast for porting the number to the calling terminal; The service adding device unit transmits a digit signal for call connection or call release to the service control system unit, and the service control system unit transmits a call connection command to the intelligent network service performing unit, and then executes an announcement broadcast release command and an intelligent network release command for the intelligent network service. Transmitting to the negative; And releasing the number porting announcement to the calling terminal from the intelligent network service performing unit, terminating the intelligent network processing procedure according to the intelligent network release command, and then performing a general call processing procedure.

10: intelligent network service execution unit (SSP)

20: Service control system unit (SCP)

30: service attachment device (IP)

A: called terminal, B: called terminal

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

1 is a block diagram to which a number porting guide service method is applied in an intelligent network switch according to an exemplary embodiment of the present invention, an intelligent network service performing unit (hereinafter, abbreviated as SSP) 10 and a service; A control system unit (hereinafter referred to as SCP) 20 and a service additional device unit (hereinafter referred to as IP) 30 are included.

The SSP 10 receives an intelligent terminal service request message (Initial Detection Point: hereinafter abbreviated as IDP) requesting to process an intelligent network service after receiving a number porting guide service from the called terminal B. And a setup request operation from the SCP 20 to the IP 30 according to the IP access indication command to set up a bearer channel so as to interact with the number guide service subscriber. Subsequently, the SSP 10 receives the hook-off signal and the incoming request message from the originating terminal A, and then transmits the incoming request message to the SCP 20. In addition, the SSP 10 commands an Establish Telephony Connection (hereinafter abbreviated as ETC) command and a Disconnect Forward Connection (hereinafter abbreviated as DFC) command from the SCP 20 and releases an intelligent network (RELease). (Hereinafter abbreviated as REL) command to control the call path to connect / disconnect the announcement and release the intelligent network to the destination terminal (B). In addition, the SSP 10 receives a call connection command from the SCP 20, and controls the call connection between the originating and terminating terminals (A, B).

After receiving the IDP from the SSP 10, the SCP 20 instructs the connection to the IP 30 to process the number transfer guide service when the subscriber is a legitimate subscriber through the profile authentication procedure of the destination terminal B. Transmits an IP access instruction command to the SSP 10. The SCP 20 transmits an ETC command to the SSP 10 and at the same time transmits a PAI (Play Announce report: hereinafter, PA) command to connect the announcement to the IP 30. In addition, SCP (20) determines the registration of the number porting guide service for the destination terminal (B), if the existing area code and the changed area code is different, the command to send a number porting announcement to IP (30) Send it. In addition, the SCP 20 receives a digit signal related to the call connection from the IP 30 and transmits a call connection command to the SSP 10 so as to be connected between the calling and receiving terminals (A, B), the DFC command and The REL command is sent to the SSP 10.

The IP 30 is used by centralizing or distributing additional services controlled by the SCP 20 or the SSP 10, and included in the SSP 10 according to the traffic level, and establishing a bearer channel received from the SSP 10. On request, it sends a setup response operation to the SSP 10 to set up a bearer channel, and receives a PA command from SCP 20 as a block for providing announcement, voice recognition and synthesis, voice messaging, data messaging, and the like. In addition, through the bearer channel set up between the SSP 10, a guide broadcast for selecting whether to attempt a local or long distance call for number porting is transmitted to the calling terminal A. Thereafter, the IP 30 receives a digit signal related to a call connection from the originating terminal A, and then transmits the received digit signal to the SCP 20.

With reference to the flowchart of FIG. 2, the number porting guide service method in the intelligent network switch having the above-described configuration will be described in more detail.

First, it is assumed that the called terminal B subscribed to the number porting service moves to a specific area in the network, and then the calling terminal A subscribed to the number ported service requested the call connection. Explain below.

The SSP 10, which has received the number porting guide service from the called terminal B, transmits an IDP requesting to process the intelligent network service to the SCP 20 (step 201).

Upon receiving the IDP from the SSP 10, the SCP 20 determines whether it is a legitimate subscriber through the profile authentication procedure of the destination terminal B (step 202). In the case of an illegal subscriber in the determination step 202, general call processing is performed without executing the number porting guide service (step 203). On the other hand, if the legitimate subscriber in the determination step 202, SCP 20 transmits an IP access instruction command to the SSP 10 according to the connection instruction to the IP 30 to process the number porting guide service ( Step 204).

Receiving an IP access instruction command from the SCP 20, the SSP 10 transmits a setup request operation for requesting bearer channel establishment to the IP 30 so that the subscriber can interact with the numbering announcement service subscriber. Transmits a setup response operation according to the bearer channel setup to the SSP 10 (step 205).

On the other hand, the SSP 10 that receives the hook-off signal and the incoming request message from the calling terminal A transmits the incoming request message to the called terminal B to the SCP 20. The SCP 20 then determines whether the terminating terminal B is registered with the number transfer guide service (step 206).

If it is not registered in the number porting guide service in the determination step 206, the general call processing is performed as the intelligent network service cannot be provided (step 203). On the other hand, if it is registered in the number transfer guide service in the determination step 206, it is checked whether the existing area code and the changed area code are the same (step 207).

If the area code changed in the check step 207 is the same, general call processing is performed without performing the intelligent network service (step 203). On the other hand, if the area code changed in the check step 207 is not the same, according to the performance of the intelligent network service transmits a command to transmit the number porting announcement to the IP (30) and at the same time transmits the ETC command to the SSP (10) (Step 208), and then send a PA command to IP 30 to terminate the announcement (step 209).

The SSP 10 receiving the ETC command from the SCP 20 controls the announcement broadcast call path to be connected (step 210), and the IP 30 receiving the PA command from the SCP 20 sends the SSP 10 to the SSP 10. After connecting the line, the announcement of the number transfer, ie, "The subscriber's telephone number using the called terminal has been changed to a long distance telephone number. Do you want to make a call using long distance telephone charges? , Press the number 2 digit for deactivation. " The announcement broadcasts to the calling terminal (A) via the SSP (10) (step 211).

Receiving a digit signal related to call connection or call release from the originating terminal A, IP 30 transmits a call connection / disconnection digit signal to SCP 20 (step 212).

After receiving the call connection digit among the call connection / disconnection digit signals from the IP 30, the SCP 20 transmits a call connection command for the call connection between the calling / receiving terminals A and B to the SSP 10, The DFC instruction and the REL instruction are sent to the SSP 10 (step 213).

Receiving a call connection command from the SCP 20, the SSP 10 controls to make a call connection between the calling / receiving terminals A and B (step 214). In addition, the SSP 10 receiving the DFC command from the SCP 20 releases the number porting announcement to the calling terminal A, terminates the intelligent network processing procedure according to the REL command received from the SCP 20, and calls the general call. Control to perform the processing procedure (step 215).

According to the present invention as described above, when the calling subscriber in the network requests a call connection to a number porting service subscriber who has moved to a specific area in the network, a call is sent to the calling terminal to select a call attempt or not. By doing so, it is possible to select whether or not to connect the corresponding call, thereby preventing charging disputes for the corresponding call, and to conveniently decide whether to select the call, which has economic benefit, and to improve the quality of service, to take the lead in the competition of subscriber acquisition. It can work.
