Abstract

PURPOSE: A local number portability service announcing method of an intelligent network switching system is provided to allow a financial benefit to a provider as well as a call origination subscriber by assigning a selection right to the origination subscriber by previously informing the subscriber before call of a charge condition, that is, whether it is a city call or a local call, and announcing him or her a charge discount service to guide him or her to a local call. CONSTITUTION: When a call origination subscriber attempts a call, a service switching point(SSP) determines whether a destination subscriber has been registered for a local number portability(LNP). If the destination subscriber has been registered for the LNP, the SSP provides an initial detection pint to a service control system(SCP). Then, the SCP verifies a local number of currently set phone number data of the destination subscriber. The SCP provides a temporary connection establishment command informing an area corresponding to the verified local number and informing that the call to the corresponding area will be charged as a local call to the SSP and connects an announcement for transmitting the corresponding area of the destination subscriber through an origination terminal to the origination subscriber by voice. After the temporary connection establishment command for informing the corresponding area is performed, a message for inducing a use of a service for a charge discount benefit by rendering the destination subscriber to listen to a certain time advertisement broadcast is transmitted through the origination terminal if the destination subscriber lives in a local area. The SCP determines whether the origination subscriber has been attempted a call to a corresponding local switching system, and if a connection is attempted between the origination subscriber and the corresponding local switching system, a forward connection disconnecting command is provided from the SCP to the SSP to disconnect the announcement to the origination subscriber and connects the call between the origination subscriber and the corresponding local switching system.

Description

Method of guiding number portability service of intelligent network switching system {METHOD FOR PROVIDING A LOCAL NUMBER PORTABILITY IN AN INTELLIGENT NETWORK}

The present invention relates to a method for providing a number portability service of an intelligent network switching system.

In general, an intelligent network is a kind of service network that processes various new services quickly and accurately and manages various services. The intelligent network is largely composed of a transport network layer, a signaling network layer, and a service network layer. The service network layer includes a service control system (SCP) and service management. It consists of a system (Service Management System), the signal network layer is composed of a Signaling Transfer Point (Signalling Transfer Point), the transport network layer is composed of a Service Switching Point (SSP).

Services provided through the intelligent network configured as described above include free phone service, credit call service, premium rate service, teleconferencing service, and virtual private network service. (Private Virtual Network service), Personal Number Service, Telephone Polling Service, Emergency Number Service, Voice Mail Service, Electronic Mail Service ), Call Me Card Service, and Local Number Portability Service (LNP).

Among these intelligent network services, number portability service is a function to continuously provide a telephone connection service to a called subscriber by switching the network connection to a moving area when the called subscriber moves to another region.

By the way, this number portability service is useful for the called subscriber, but it was quite unfair for the calling subscriber. That is, when the called subscriber in Seoul tries to make a phone call to the called subscriber while the called subscriber switched the network connection from the original subscription area (eg, Seoul) to another area (eg Busan), The subscriber attempts to call the original called party's telephone number, such as 02-123-4567, but the caller's billing data is not available because the network connection switches to Busan, for example, 051-123-4567, rather than Seoul. Charged in long distance currency, not currency.

Accordingly, the long distance call charge is subsequently charged to the calling subscriber without the calling subscriber not aware, resulting in economic damage to the calling subscriber.

In addition, once a subscriber is affected will be reluctant to call, this has caused a problem that not only the subscriber but also the economic loss.

Accordingly, the present invention has been made to solve the above-described problem, and when a particular calling party attempts to set up a call to a called party subscribed to the number portability service, the calling condition is a billing condition for the calling party, that is, a local call or a long distance call. The number portability of the intelligent network switching system, which informs the subscriber in advance before making a call, gives a choice to the outgoing subscriber, and guides the billing discount service through listening to the broadcast to induce a long distance call, thereby providing economic benefits not only to the outgoing subscriber but also to the operator. The purpose is to provide a service guidance method.

In order to achieve the above object, the present invention provides a method for guiding a local number portability service of an intelligent network switching system composed of a service switching point and a service control point. Is attempted, determining at the service exchanger whether the called subscriber is registered as a number portability service; As a result of the determination, if the called subscriber is registered as the number portability service, providing an initial detection point provided from the service exchanger to the service control system; Verifying, in the service control system, the area code of the currently set telephone number data of the called subscriber; When the predetermined area code is verified, the announcement broadcast for transmitting the corresponding area of the called subscriber to the calling subscriber by providing a Establish Temporary Connection command to the service exchange to inform the corresponding area corresponding to the verified area code. Connecting the; It is determined whether an originating subscriber attempts to connect to the local exchange, and when a call connection is attempted between the originating subscriber and the corresponding local exchange, a Disconnect Forward Connection command provided from the service control system is issued. It provides to provide a number portability service guide method of the intelligent network switching system comprising the step of releasing the announcement broadcast connection to the calling subscriber, and connecting the call of the calling subscriber and the local exchange period.

104: service control system (SCP)

106: Intelligent Information System (IP)

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

1 is a schematic block diagram of an intelligent network switching system used in the method according to the present invention, an intelligent network service switching point (hereinafter referred to as SSP) 102, and a service control system (hereinafter referred to as SSP). , Abbreviated as SCP) 104, and Intelligent Peripheral (hereinafter, abbreviated as IP) 106.

SSP 102 is an electronic exchange that connects a service user with an intelligent network. The SSP 102 recognizes an intelligent network service call in a telephone user's call, connects the call to a desired destination according to information required for processing the intelligent network service call, and calls or calls. Stores the called number internally. According to the present invention, the SSP (102) is a SCP 104 that describes the call attempt request from the originating terminal 100, when the called subscriber is subscribed to the Local Number Portability (hereinafter referred to as LNP) Report as.

SCP 104 has service logic and data that manages the entire process of intelligent network service, and can provide various intelligent network services with one SCP and use different SCPs for each service. According to the present invention, the SCP 104 forms a bearer channel between the originating terminal 100 and the IP 106 according to the result of acknowledgment of the number portability service call by the SSP 102, and prompts the IP 106 for a predetermined guidance. To provide the voice message data to the calling terminal (100). In other words, when determining the number portability service registration of the called party, the SCP 104 handles routing to another local exchange or other network in the network when the existing number and the area number of the changed number are different.

IP 106 is connected to one or more SSPs 102 and SCP 104 via a signal network, and has customized guided voice messages, voice recognition, speech synthesis, voice recording, and dual tone multi frequency (DTMF). It has resources such as digit collectors, protocol converters, etc., and provides flexible interaction between users and intelligent networks. As described above, the IP 106 provides the subscriber with a guide voice message, collects the telephone number and the like of the called subscriber provided from the calling terminal 100 and provides it to the SCP 104.

Hereinafter, the above-described configuration will be described in detail with reference to a timing diagram of FIG. 2 attached to a number portability service announcement broadcast transmission process of an intelligent network switching system according to an embodiment of the present invention.

As shown in Fig. 2, when call processing is attempted from the originating subscriber, the SSP 102 determines whether the called subscriber is registered with the number portability service, that is, the LNP.

As a result of the determination, if the called subscriber is registered as an LNP, the initial detection point provided from the SSP 102 is provided to the SCP 104.

When an initial detection point is provided to SCP 104, SCP 104 verifies the area code of the currently set phone number data of the called party.

If a given area code, for example 051, is validated as the current area code, SCP 104 informs the area corresponding to the verified area code and announces an announcement link to indicate that calls to that area are subject to long distance calling charges ( It provides the Establish Temporary Connection) command to the SSP (102) to connect the announcement for transmitting a voice to the calling subscriber through the calling terminal (100).

Such announcement may be, for example, a message "Number portability service. The current subscriber is in Busan. Long distance charges apply when making a call."

In addition, after performing the command to connect the announcement to inform the region, whether to listen to the commercial for the billing discount service, that is, a service that receives a discount rate by listening to the commercial for a predetermined time when the area of the called subscriber is out of the city The message inducing use is sent out through the calling terminal 100.

The announcement message may be, for example, a message "If you make a call, you may receive a discount rate through listening to an advertisement. Please press 1 for a discount call and 2 for a general call." In this case, the reason for querying the calling subscriber about the selection of the discounted call and the general call is that the caller may not need to discount the call rate through listening to the commercial when the calling subscriber wants an urgent call. Those skilled in the art will readily know.

On the other hand, SCP 104 determines whether the calling subscriber attempts to make a call to the local exchange, that is, a signal for selecting a discount call or a general call from the calling terminal 100 for call connection between the calling subscriber and the called party. If it is determined whether or not the call is attempted, and a call connection is attempted during the local exchange, the SSP 102 is provided to the calling subscriber by providing a disconnect forward connection command provided from SCP 104. Release the broadcast connection and connect the calling subscriber with the call of the local exchange period.

Therefore, the calling subscriber can make a call with the called subscriber in the number portability service according to the selection of the calling subscriber.

As described above, the present invention has an effect of preventing the application of long-distance billing regardless of the intention of the calling subscriber.
