PSTN SERVICE NETWORK USING THE PRI CONVERTER WITH IVR FUNCTION}

The present invention relates to a telephone service network, and more particularly, to a telephone service network using a PRI converter with an IVR function to provide an additional service to an ISDN PRI subscriber.

Intelligent Network is a network that connects a computer to a conventional public telephone network so that new technologies can be easily integrated.The central network is used to control various exchanges or terminals in the network through a central service control computer. It is a network connected organically by line.

Such an intelligent network has a transmission network for exchanging and transmitting information such as voice and data, a signal network for transmitting control signals between elements of the transmission network through a common line signaling method (No. 7), and an intelligent network service while retaining data on users. It consists of a service network to control the.

The additional services provided by the intelligent network may include an incoming billing service, a credit call service, a personal number service, an internal internal calling device service, an emergency response service, a public information service, and a ring back tone service. In order to provide each of these additional services, it is necessary to build a separate intelligent network (or CTI) and then use the functions of the intelligent network. However, if the telephone service network can provide a variety of additional services without establishing a separate intelligent network (or CTI) will be a more convenient form.

Accordingly, the present invention has been made to meet the above needs, and provides IVR functions such as announcement, playback, recording, and DTMF collection to provide telephone supplementary services to ISDN PRI subscribers without establishing an intelligent network or CTI. The purpose is to provide a telephone service network using the built-in PRI converter.

In order to achieve the above object, according to the present invention, a telephone service network using a PRI converter with a built-in IVR function to provide an additional service to an ISDN PRI subscriber is called when an arbitrary party is called by dialing in a telephone network environment. An exchanger for connecting the called party's line; A PRI converter connected to the exchange and using SS7 ISUP signaling to provide additional services to the caller / receiver by embedding IVR functions such as message playback, recording, and DTMF collection; A private branch exchange connected to the PRI converter and using an ISDN PRI signaling to connect an extension telephone or an external line; And an ISDN PRI subscriber telephone connected to the private branch exchange.

The telephone service network may further include a management server that provides an subscriber with an interface for setting an additional service while managing the PRI converter in an Internet network environment; A database storing data relating to an additional service provided by the PRI converter; And an ISDN PRI subscriber PC connectable to the management server.

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

1 is a telephone service network to which the PRI converter with built-in IVR function is applied in a telephone network environment according to the present invention, the telephone exchange network 110 through the exchange 120, PRI converter 130, private branch exchange (PBX: 140), And ISDN PRI subscriber phone 150 are sequentially connected.

The switch 120 connects the line between the calling party and the called party when the calling party calls any other party by dialing. The PRI converter 130 is connected to the exchanger 120 and uses SS7 (Signaling System 7) ISUP signaling to each other, and has a built-in interactive voice response (IVR) function such as message playback, recording, and DTMF collection. Various call additional services can be provided to the called party.

The SS7 is a protocol for providing a specific service in a voice network, and is a protocol for managing voice call information and data communication connection information. The SS7 manages meta data of voice communication and data communication, Based on the integrated environment of data communication, various intelligent network systems can be developed.

IVR is also a two-way voice response, an application that has the ability to use touch tones or voice prompts to navigate around a database or process. The system first guides the information provided to the customer, receives the customer's specific ID, retrieves the information from the host (server), and then provides voice information.

The private branch exchange (PBX) 140 is connected to the PRI converter 130 and uses ISDN PRI (Integrated Services Digital Network Primary Rate Interface) signaling, which is connected to an extension while sharing a predetermined number of external telephone lines. Automatically connect the phone between users.

Here, the PRI (Primary Rate Interface in ISDN) is a primary rate interface, which has several B and D channels, which carry data, voice and other services, and the D channel provides control and signaling information. To carry. PRI users can receive services at 1.544 Mbps on T-1 and 2.048 Mbps on E1. PRI uses the Q.931 protocol on the D channel.

Now, to help the understanding of the present invention, a case in which an ISDN PRI subscriber receives a call from an external caller will be described. When an external caller makes a call using his phone (not shown), the incoming call through the exchange 120 is connected to the PRI converter 130 via SS7 ISUP signaling, and the PRI converter 130 is ISDN PRI signaling. The call is connected to the ISDN PRI subscriber phone 150 by being connected to the private branch exchange 140 through.

This time, let's consider a case where an ISDN PRI subscriber calls an external called party. When the ISDN PRI subscriber makes a call using his phone 150, subscriber phone 150 is connected to PRI converter 130 via ISDN PRI signaling via private branch exchange 140, and PRI converter 130 Is connected to the switch 120 via SS7 ISUP signaling, so that the call is connected to an external called telephone (not shown).

Therefore, the caller and the receiver make various phone additional services provided by the conventional intelligent network equipment by using the PRI converter 130, which is located in the middle of the above-mentioned call connection process and has an IVR function such as recitation, recording, and DTMF collection. I can provide it to

2 is a telephone service network to which a PRI converter with an IVR function is built in a telephone network and an internet network environment according to the present invention, and includes a switch 120, a PRI converter 130, and a private branch exchange (PBX) through the telephone network 110. 140, and the ISDN PRI subscriber telephone 150 are not only sequentially connected, but also the database 160, the management server 170, and the subscriber PC 190 are connected to the PRI converter 130 through the Internet network 180. Connected.

The management server 170 provides a subscriber with a user interface for setting up a telephone supplementary service while managing the PRI converter 130. The database 160 stores data regarding telephone supplementary services provided by the PRI converter 130. Accordingly, the ISDN PRI subscriber may change the function of the telephone supplementary service set in the PRI converter 130 by accessing the management server 170 through his PC 190.

On the other hand, it is possible to provide a ring tone (coloring) service through the PRI converter 130, ISDN PRI subscribers can access the management server 170 through their PC 190 to manage the sound source for coloring.

In detail, the ISDN PRI subscriber may change the sound source used for coloring by accessing the management server 170 through his PC 190. That is, one of a plurality of sound sources stored in the database 160 may be selected or a new sound source may be added. At this time, the ISDN PRI subscriber may dial the set access number of the PRI converter 130 using his / her telephone 150 to record his / her voice and use it as a coloring sound source.

This time, let's take a look at the process of providing coloring service in case ISDN PRI subscriber receives incoming call from external caller. When the incoming call through the exchange 120 is connected to the PRI converter 130 through SS7 ISUP signaling, the PRI converter 130 goes to the ISDN PRI subscriber phone 150 via the private branch exchange 140 via the ISDN PRI signaling. While attempting a call, the caller hears the coloring sound source. Subsequently, when the ISDN PRI subscriber receives a call and the call is connected, the coloring service is terminated and a voice call path between the calling telephone and the ISDN PRI subscriber telephone 150 is established.

As described above, the telephone service network using the PRI converter with the built-in IVR function can provide various telephone supplementary services using the PRI converter without constructing a separate intelligent network. On the other hand, the present invention is not limited to the above-described embodiment and can be utilized or applied in various ways in the field of telephone service network by those skilled in the art without departing from the technical spirit.
