Abstract

PURPOSE: A method for connecting telephone numbers in an intelligent network exchange(INX) is provided to make the INX request a call connection to an incoming terminal when an originating terminal requires the call connection with a telephone number announced by an operator, so as to perform the call connection between the two terminals. CONSTITUTION: A service switching point(SSP) receives a call connection message from an originating terminal. The SSP transmits the message to an operator through a service control point system(SCP) and an operator terminal. If the SSP senses a call connection signal, the SSP transmits an initial detection point(IDP) message to the SCP. The SCP decides whether a subscriber is registered in a telephone connection service. If not, the SCP performs a normal call processing. If the subscriber is registered, the SCP starts an intelligent network service and retrieves a database, to search a telephone number of an incoming terminal. The SCP reads the searched telephone number and transmits the number to an operator terminal. An operator transmits announcement requesting messages to the SCP. The SSP switches a speech path. An intelligent peripheral(IP) receiving a play announce report(PA) command from the SCP connects the speech path to the SSP. The IP receiving a digit signal from an originating terminal transmits the digit signal to the SCP. The SCP transmits a disconnect forward connection(DFC) command to the SSP. The SSP cancels an announcement to the originating terminal. If the operator terminal receives the digit signal, the operator terminal transmits a DN signal and a switching function scenario button signal to the SCP. The SCP transmits a termination connecting message to the SSP. The SSP switches a speech path between the originating and the incoming terminals, to make the speech path connected.

The SSP 10 receives the call connection request message from the calling terminal A registered with the telephone number connection service, and then switches the received call connection request message to the operator through the SCP 20 and the operator terminal 30. A call connection request message is sent to the (exchange operator) C to switch the call connection between the calling terminal A and the operator C. FIG. After the call is connected between the calling terminal A and the operator C, the SSP 10 detects the call connection signal and sends an initial detection point (hereinafter, referred to as IDP) message according to the SCP (20). To send). Subsequently, the SSP 10 supplies Establish Telephony Connection (hereinafter abbreviated as ETC) command and billing data from the SCP 20 to record on magnetic tape. Receives commands and switches them to suit each command. In addition, the SSP 10 receives a disconnect forward connection (hereinafter abbreviated as DFC) command from the SCP 20, releases the announcement to the calling terminal A, and requests for incoming connection from the SCP 20. Receives a message to switch the call path between the calling and receiving terminals (A, B), and finally, after receiving the intelligent network service blocking (RELease: hereinafter, REL) command from the SCP 20, the calling terminal ( The call path between A) and the called terminal B is controlled.

The SCP 20 has a database 25 internally, receives an IDP message from the SSP 10, and passes the profile authentication procedure of the calling terminal A to a legitimate subscriber (telephone number connection service). Registered subscriber), the database 25 is searched to find the telephone number for the called terminal B inquired by the calling terminal A. FIG. As a result of the search, that is, the telephone number for the called terminal B is read from the database 25 and transmitted to the operator terminal 30, and the DN signal of the calling / receiving terminals A and B is received from the operator terminal 30. And receives the signal according to the switching function scenario button input and transmits the incoming connection request message to the SSP (10). In addition, the SCP 20 transmits an ETC command and an FCI command to the SSP 10, and transmits a Play Announce report (hereinafter, abbreviated to PA) command to the IP 40 to SSP (10). 10) and the call path between IP 40 is required to be connected. The SCP 20 transmits the DFC command according to the release of the announcement and the REL command according to the blocking of the intelligent network service to the SSP 10.

The operator terminal 30 is provided with a switching function scenario button (for example, a button "114"), which is not shown, and receives the telephone number for the destination terminal B from the SCP 20 to be checked by the operator C. Displayed so as to transmit, and transmits the DN signal and the switching function scenario button input signal of the calling / receiving terminal (A, B) input by the operator (C) to the SCP (20).

The IP 40 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 the announcement, voice recognition and synthesis, and voice messaging. , A block that provides data messaging, etc., connects the SSP 10 with a call path in response to receiving a PA command from the SCP 20, and announces the announcement of the telephone number search result (for example, "the number you want is XXX -YYYY. If you want to connect right now, press 1 ") is sent to the calling terminal (A) through the SSP (10). Then, after receiving a digit signal (signal for "1" to be connected) from the calling terminal A, the received digit signal is transmitted to the SCP 20.

With reference to the flowchart of FIG. 2, the telephone number connection service method in the intelligent network switch | network which has the above-mentioned structure is demonstrated in more detail.
