Abstract

PURPOSE:To attain a proper countermeasure even if a transmitter-receiver is hooked on the way of talking of a celler by sending caller information to a callee depending on the request from the callee. CONSTITUTION:The caller 1 and a channel section 5 of a trunk 4 are connected and a caller telephone number from an exchange 3 is received and stored by a reception/storage section 6 of the trunk. Then a callee start signal is sent from the channel section 5 of the trunk succeedingly and the caller 1 and the callee 2 are talked by the reply of the callee. Since the trunk 4 holds the line between the caller 1 and the callee 2 even when the caller 1 hooks on the transmitter-receiver in case the callee 2 requires the telephone number of the caller 1, a sending section 8 is started by applying caller information request operation. The sending section 8 uses a voice synthesis section 9 to convert the caller telephone number stored in the reception/storage section 6 into voice, which is sent to the callee 2. The callee 2 uses the received caller telephone number to confirm the caller 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system for transmitting calling party information of a calling party connected via a switching device to a called party.

(Prior Art) When a calling party and a called party are connected through a switching device, if the calling party hangs up the handset first, the connection is released regardless of the state of the called party. Therefore, if the caller hangs up before the called party identifies himself or knows where he is, the called party will be unable to respond to the call. Since this is not possible, the request to confirm the caller or repeat the call cannot be fulfilled.

Traditionally, this problem is handled by treating the called party as a special subscriber;
The system was configured to hold connected lines as a recovery process (last party release) in which the line would not be released until a special subscriber hung up the handset.

Thereby, it is also possible to call the caller who has hung up the handset with a re-calling signal (bell ringing signal).

If the calling party does not respond even if the calling party is called with a recall signal or the like, there is a drawback that the called party cannot identify the calling party.

The present invention aims to improve the above-mentioned drawbacks of the prior art.

(Means for Solving the Problems) A feature of the present invention for achieving the above object is that in a telephone switching device, a trunk connected to the switching device connects a calling party and a called party via the switching device. A communication path unit that connects and suspends the connection until the called party performs a disconnection operation, a reception storage unit that receives and stores calling party information from the switching device, and a calling party information request signal from the called party. and a transmitting unit that transmits the calling party information accumulated in the receiving storage unit to the called party according to the detection by the detecting unit. The calling party information transmission method is to send the information to the called party.

(Function) In the above configuration, the first communication path section holds the line even when the calling party hangs up the handset, and the calling party information (for example, the calling party's telephone number) is transmitted in response to the called party's request. Sent to the called party.

The transmission is performed using, for example, a voice synthesized by a voice synthesizer. Therefore, the called party can obtain calling party information regardless of the calling party, and one object of the present invention is achieved.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention. 1st
In the figure, a calling party 1 dials the number of a called party 2, and is connected to a trunk 4 that has an interface with the called party under the control of a switching device 3, and is connected to the called party via a line. The configuration is as follows. Further, in this embodiment, the calling party's telephone number is used as the calling party information.

Communication path 5 between calling party 1 and trunk 4 via switching device 3
is connected. This communication line section 5 has a function (last party release) that holds the line between the calling party 1 and the called party 2 even after the calling party 1 hangs up the handset and does not release the line.

The calling party 1 and the communication path section 5 of the trunk 4 are connected, and the calling party's telephone number is received from the switching device 3 and stored in the receiving/storing section 6 of the trunk.

Subsequently, a called party activation signal is sent from the communication path section 5 of the trunk, and in response to the called party's response, the calling party 1 and the called party 2 communicate. When calling party 1 hangs up, this trunk 4 holds the line between calling party 1 and called party 2, so that called party 2 needs calling party 1's phone number. In this case, by performing a calling party information request operation, a PB double signal is sent from the called party to the trunk 4 as a calling party information request signal. In the trunk, the PBB output section 7 outputs the PB as a caller information request signal.
When the double signal is detected, the sending unit 8 is activated.

The sending section 8 controls the receiving/storing section 6 and the speech synthesizing section 9, converts the calling party's telephone number stored in the receiving/storing section 6 into speech by the speech synthesizing section 9, and sends it to the called party 2. do. called party 2
The caller 1 is verified using the received caller telephone number.

Trunk 4 is restored by the callee's disconnect operation, and the caller 1
The connection between and called party 2 is also opened.

In this embodiment, the calling party's telephone number is sent to the called party by voice, but instead of the voice synthesis section, the PB signal generation section can be connected to the sending section to send out the PB double signal. be.

In addition, the transmission section is capable of inputting audio from the speech synthesis section, and is also provided with a PB signal generation section.

By making it possible to input the FB multiplied signal, multiple PB multiplied signals are used as a caller information request signal from the called party, and when a specific PB multiplied signal (for example, by pressing the L button) is used, the voice from the speech synthesis section is input. It is also possible to send out the calling party's telephone number in the case of other specific (for example, boxed) PB multiplied signals, to send out the PB multiplied signal calling party number of the PB signal generator.

Note that even in the case of a configuration in which a plurality of trunks have a common receiving/storage unit for calling party's telephone number, this can be implemented by receiving the corresponding trunk number and calling party's telephone number from the switching device.

Furthermore, even if the called party is accommodated on the subscriber circuit side of the switching equipment, it can be easily implemented if the system is configured to have the same function as an intra-office connection trunk, as shown in FIG.

(Effects of the Invention) As described in detail above, according to the present invention, the calling party's telephone number can be learned through the operation of the called party, so that the calling party may hang up the handset during the call. Appropriate measures can be taken even in the event of an emergency. This can be expected to have a great effect since special subscribers often have urgent calls. Also,
It can be used as a means of confirming the caller's telephone number even if the call is made normally, and is also effective in cases where the caller has given his or her telephone number by mistake.

Furthermore, if the PB double signal of the PB telephone terminal is used as the calling party's telephone number request signal, and the calling party's telephone number is transmitted by voice, there is no need to install any special equipment on the terminal of the called party. be.
