Abstract

PURPOSE: An originating number transmission method using guide broadcasting is provided so that a subscriber using a general terminal can receive a originating number if he has been registered in the originating number receiving service. CONSTITUTION: An outgoing call processing part transfers a digit number transferred from a transmitting terminal to a number translation part(200). The digit number transferred from the outgoing call processing part is translated in the number translation part(201). As a result of the translation, if it is an incoming call request message, the incoming call request message is transferred to an incoming call processing part(202). It is judged whether a response message from the receiving terminal is transferred according to the incoming call request message(203). The incoming call processing part transmits call sound to the transmitting terminal continuously(204). It is discriminated whether an originating number transmission service using guide broadcasting has been registered(205). If the originating number transmission service using guide broadcasting has been not registered, call connection is made with the receiving terminal(206). If the originating number transmission service using guide broadcasting has been registered, the originating number is requested to the outgoing call processing part(207).

Description

Calling number transmission method using announcement

The present invention relates to a method of transmitting a calling number of an exchange, and more particularly, to a method of transmitting a calling number using an announcement broadcast, which enables an outgoing number to be sent to a called terminal by using an announcement when an incoming call is generated from an originating terminal. will be.

Typically, the special service provided by the exchange includes a caller ID call service that sends the telephone number of the caller terminal to the called terminal. The calling number transmitting service transmits the telephone number of the calling terminal to the called terminal using a dual tone multi frequency (hereinafter, referred to as DTMF) signal to inform the called subscriber of the calling subscriber's telephone number. Is done in a way.

That is, when the incoming call is received from the calling terminal, the DTMF signal transmits the DTMF signal of the calling terminal stored in the calling exchange to the called terminal using the DTMF equipment of the called exchange. Therefore, the called terminal should receive the DTMF signal transmitted from the called exchange and then translate it into a data form that can be recognized by the subscriber. For this reason, in order to receive the calling number, there was a problem in that a terminal having a function of receiving and translating a DTMF signal must be purchased separately.

Accordingly, the present invention has been made in view of the above-described problems, and an object thereof is to provide a calling number transmission method for sending out a calling number so that a subscriber using a general terminal can also receive a calling number if he is registered with the calling number receiving service. In providing.

Another object of the present invention is to provide a caller ID transmission method using the announcement broadcast to provide information on the calling party to the called subscriber using the announcement broadcast.

In order to achieve the above object, the method for transmitting a calling number in the present invention includes, when an incoming call response is made by a called terminal, retrieving special service registration information for the called terminal and maintaining a ring tone provided to the calling terminal; Requesting an outgoing number from an outgoing call processor if the outgoing number transmission service using the announcement is registered as a result of the search; Transmitting the calling number to the called call processor by referring to the calling number stored in the calling number storage unit by the request; Transmitting the call connection ring to the called terminal when the calling number is transmitted, and transmitting the transmitted calling number to the announcement broadcasting transmitter when the hook-off signal is transmitted from the called terminal; Transmitting voice data corresponding to the calling number together with the announcement broadcast to the called terminal; If a hook flash signal is transmitted from the called terminal receiving the announcement broadcast, a call connection is made with the calling terminal.

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

FIG. 1 is a block diagram illustrating a method for transmitting a calling number using a guide broadcast according to a preferred embodiment of the present invention, and includes a calling terminal 10, a switch 20, and a called terminal 30.

The calling terminal 10 dials a digit number arranged in the calling terminal 10 to make a call with the called terminal 30. As a digit number example according to the present invention, it is used as a telephone number of the called terminal 30. By dialing the digit number of the called terminal 30 in sequence, it is possible to make a call with the called terminal 30. The digit number input from the calling terminal 10 is transmitted to the exchange 20.

The exchanger 20 internally transmits the outgoing call processor 21, the number translation unit 22, the incoming call processor 23, the outgoing number storage unit 24, the database 25, and the announcement broadcast. The part 26 is provided.

The outgoing call processor 21 transmits the digit number transmitted from the outgoing terminal 10 to the number translation unit 22.

The number translation unit 22 translates the digit number, and transmits the translated result, that is, the call request message to the destination terminal 30, by the originating call processing unit 21 to the incoming call processing unit 23.

The incoming call processor 23 receives the call request message sent from the outgoing call processor 21, and searches the database 25 to determine whether the called terminal 30 transmits the calling number transmission service using the announcement. If confirmed and registered, the calling number is requested to the calling call processor 21 in order to receive the calling number stored in the calling number storage unit 24. When the calling number is transmitted from the calling call processor 21, the ring according to the call connection is sent to the called terminal 30, and the calling number is sent to the announcement broadcast sending unit 26.

The calling number storage unit 24 is a database that stores the telephone number of the calling terminal 10, and the calling number is referred to by the calling call processor 21.

The database 25 stores the special service registration matters, and searches by the incoming call processor 23 whether the terminating terminal 30 registers the calling number transmission service using the announcement broadcast.

The announcement broadcast transmitting unit 26 loads voice data corresponding to the calling number transmitted from the incoming call processing unit 23 along with the announcement broadcast on the communication path and transmits it to the called terminal 30.

The receiving terminal 30 selects the state of the hook flash or the hook on after receiving the announcement of the calling number from the announcement broadcast sending unit 26. In the above-described selection, when the hook flashes, the call path is connected and the call is connected with the calling terminal 10, while when the hook is turned on, the call fail signal is notified to the calling terminal 10.

With reference to the flowchart of FIG. 2, a caller ID transmission method using the announcement broadcast according to the present invention having the above-described configuration will be described in detail.

First, the subscriber hooks off the handset / receiver to talk to the called terminal 30 through the calling terminal 10, and then dials the digit number, so that the digit number input from the calling terminal 10 is dialed. It is transmitted to the call processor 21. The originating call processor 21 transmits the digit number transmitted from the originating terminal 10 to the number translation unit 22 (step 200).

The digit number transmitted by the calling call processor 21 is translated by the number translation unit 22 (step 201). If the result of translation in the number translation section 22 is a call request message to the called terminal 30, the call request message is sent to the call receiver 23 (step 202).

After confirming the call request message sent by the originating call processor 21, it is determined whether a response message has been transmitted from the called terminal 30 according to the call request message (step 203). When the response message is transmitted in step 203 described above, the incoming call processor 23 refers to the database 25 to retrieve the special service registration information for the called terminal 30, and makes a ring tone to the calling terminal 10. Is continuously sent (step 204).

As a result of the search, it is determined whether or not to register the caller ID service using the announcement (step 205). If the calling number transmission service using the announcement broadcast is not registered in the above-described determination step 205, the call path 40 is connected, and then the call connection is made with the called terminal 30 (step 206). On the other hand, if the calling number transmission service using the announcement broadcast is registered in the determination step 205, the calling number processing unit 21 requests the calling number (step 207).

The outgoing call processor 21, which has requested the calling number, searches for and indexes the calling number of the calling terminal 10 stored in the calling number storage 24, and then sends the calling number to the called call processor 23. (Step 208).

The incoming call processor 23 sends a call connection ring to the called terminal 30 when the calling number is transmitted by the calling call processor 21 (step 209). In addition, when the hook-off signal is transmitted from the receiving terminal 30 that has received the ring, the calling number is transmitted to the announcement broadcast transmitting unit 26 (step 210).

The announcement broadcast transmitting unit 26 loads voice data corresponding to the calling number transmitted from the incoming call processing unit 23 along with the announcement broadcast on the communication path 40 and transmits it to the called terminal 30 (step 211).

The receiving terminal 30 receiving the announcement of the calling number from the announcement broadcasting transmitting unit 26 determines the state of the hook flash according to the call connection or the hook on according to the call connection failure after listening to the calling number. Step 212). When the hook flashes in the above-described determination step 212, the call path 40 is connected and connected to the call terminal 10 (step 206). On the other hand, if it is hooked on in the determination step 212, it notifies the calling terminal 10 of the call failure signal (step 213).

As described above, the present invention transmits a calling number using a guide broadcast when a call is requested to a subscriber subscribed to a calling number receiving service, so that the calling number can be sent to a general terminal instead of a terminal equipped with a special function for receiving a calling number. There is an advantage to be provided.
