Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange system, and more particularly to a telephone exchange system configured to perform a connecting operation between terminals by making a call from a calling side.

[Conventional technology]

In the conventional telephone exchange system, the calling side recognizes the subscriber number of the called side, calls from the terminal to activate the exchange, and then sends a dial signal of the called party's subscriber number to the exchange. The exchange identifies the called-side terminal based on the dial signal and sends a simple call signal (without the calling-side information) to the called-side terminal. The exchange immediately establishes a connection between each terminal of the calling side and the called side based on the response from the called terminal in response to the ringing tone.

[Problems to be Solved by the Invention]

However, in such a conventional example, the calling party is
By designating the subscriber number that recognizes the incoming signal, the called party can be identified before the call. On the contrary, there is a situation in which the called party cannot identify the calling party at the time of answering the call and can only identify and recognize the calling party only in the mutual call after answering the call. It was

In other words, in the conventional exchange, there is a problem in that the called party cannot respond to the calling party by the calling signal issued from the exchange through the terminal, but temporarily suspends the action that has been performed up to that point.

[Object of the Invention]

In the present invention, the disadvantages of the conventional example are improved,
In particular, it is an object of the present invention to provide a telephone exchange system capable of automatically and easily outputting information about a calling side terminal to a called side terminal in a recognizable expression.

[Means for solving the problem]

In the present invention, the signal of the subscriber number of the receiving side terminal is accepted from the calling side terminal, and the calling signal is output and connected to the calling side terminal and the receiving side terminal corresponding to the called side subscriber number. In a telephone exchange system, a local exchange connected to a calling side terminal is equipped with a subscriber information storage means for storing in advance subscriber information such as a subscriber number and an address of the calling side terminal. Reception information storage means for temporarily storing subscriber information sent from the subscriber information storage means, and voice synthesis for converting the subscriber information into a voice signal and outputting the voice signal to the other-station exchange connected to the switch. The circuit and the circuit are installed side by side.

Moreover, the local exchange has a function of outputting the subscriber number signal of the terminating side terminal and the subscriber information corresponding to the subscriber number of the originating side terminal to the local exchange, so that the local exchange can make a call. It is configured to have a function of outputting a voice signal based on subscriber information to the called terminal in accordance with the output of the signal. This aims to achieve the above-mentioned object.

Example of Invention

An embodiment of the present invention will be described below with reference to FIG.

In the embodiment shown in FIG. 1, an exchange which receives a signal relating to a called party subscriber number output from the calling side terminal 1 and sends it to the called side terminal 2 in the calling side terminal 1.
It has 3 and 4.

Among these, the local exchange 3 to which the calling side terminal 1 is connected is equipped with a subscriber information storage means 5 for storing subscriber information regarding the calling side terminal 1.

In addition, the remote exchange 4 connected to the called terminal 2
Is provided with a reception information storage means 6 for temporarily storing the subscriber information sent from the subscriber information storage means 5 and a voice synthesis circuit 7 for converting the subscriber information into a voice signal and outputting the voice signal. ing.

More specifically, the local exchange 3 has a changeover switch section 3A and a transmission signal 21 from the originating side terminal 1 input through the changeover switch section 3A, which is connected to its own station or to another station. Outgoing register trunk section 3B for identifying whether the connection is
Outgoing sender trunk section 3C for temporarily storing outgoing signal 21
And an outgoing trunk section 3D for sending the outgoing signal 21 to the incoming trunk section 4D of the other-station switch 4.

In this case, when the outgoing call register trunk section 3B identifies that the outgoing call signal 21 is to be connected to the remote exchange 4, the outgoing call signal 21 which is the subscriber number of the called party is output to the sender trunk. It is designed to be temporarily stored in part 3C. After that, the outgoing signal 21 is output from the outgoing trunk portion 3D to the other-station switching device 4.

Then, together with the subscriber number of the called party sent to the incoming trunk section 4D of the other-station switch 4, the calling party subscriber information is transmitted via the outgoing trunk section 3D, and the incoming trunk section 4D of the other-station switch 4 is transmitted. It is adapted to be temporarily stored in the reception information storage means 6 via the route. That is, the local exchange device has a function of outputting the subscriber number signal and the subscriber information corresponding to the subscriber number signal to the other exchange device.

The subscriber information transmitted in this case is previously stored in the subscriber information storage means 5 in the local exchange 3.

In the other side exchange 4 of the called side, the outgoing trunk section 3D of the calling side
The receiving side subscriber number sent to the incoming trunk section 4D via the receiving side is received, and the communication path to the receiving side terminal 2 is identified and set.

Here, the remote exchange 4 on the receiving side is provided with a changeover switch section 4A.
And a ringing tone trunk section 4B, an incoming trunk section 4D, and a ringing signal trunk section 4C, which are provided side by side with the changeover switch section 4A.

Next, when the call path is set by the remote exchange 4 on the receiving side, the ringing tone trunk section 4B immediately operates, and the ringing tone for notifying that the receiving side terminal 2 is ringing is given by the incoming trunk section.
It is sent to the terminal 1 on the calling side through the 4D and the outgoing trunk section 3D.

On the other hand, in synchronism with this, the receiving side terminal 2 receives the calling signal 22 output from the calling signal trunk section 4C, together with the calling side subscriber information such as the calling side subscriber number and address. Is transmitted as a voice signal via the voice synthesis circuit 7. That is, the other-station switch 4 has a function of outputting a voice signal based on subscriber information to the called terminal 2 in addition to the output of the calling signal.

Therefore, on the called side, since the calling side subscriber information is output along with the call signal output from the called side terminal 2, it is extremely easy to determine whether or not to accept the response for talking with the calling side. Can be done

When the call is not desired, switching to an answering machine or disconnection of the call path by resetting is performed. on the other hand,
When a call is selected, the exchange 4 on the receiving side detects this from the response from the terminal 2 on the receiving side. Then, the called terminal 2, the incoming trunk section 4D, the outgoing trunk section 3D and the calling terminal 1 are connected, and the other trunks are disconnected.

With the above operation, a call between the calling terminal 1 and the called terminal 2 becomes possible.

In the process of connecting the call path between the originating side terminal 1 and the terminating side terminal 2, as described above, the terminating side is the calling side subscriber who is registered in advance in the exchange before responding to the calling side call. By obtaining the information by voice, it becomes easy to determine whether or not to accept the call. As a result, in the telephone exchange in which the called side is called under the initiative of the calling side,
The called side can know the calling side before the call instead of knowing the calling side by the call, and can be placed in an equal position in the call. In addition, the called party can reserve the right to call by obtaining information on whether or not to accept the call.

〔The invention's effect〕

As described above, according to the present invention, the local exchange has a function of storing in advance subscriber information such as the subscriber number and address of the calling terminal, and the local exchange exchanges the subscriber number signal with the subscriber number signal. Since the subscriber information corresponding to the subscriber number signal is output to the other-station switch, and the other-station switch outputs a voice signal based on the subscriber information to the called terminal together with the output of the calling signal, the called side Information about the calling terminal can be automatically and easily output to the terminal in an easily recognizable expression.

Further, the subscriber information is transferred to the terminating exchange by calling from the originating terminal, and the terminating side exchange sends a voice signal of the subscriber information together with a calling signal to the terminating side terminal. There is an advantage that the user of the terminal can know the subscriber information on the calling side such as the subscriber number and address by voice before making a response by the calling signal.

This is because in order to protect the interests of the called party, the calling party is in a leading position because the called party specifies the called party's subscriber number when making a call. It is intended to provide a user with means for identifying a calling party based on the subscriber information of the calling party by voice before making a call with the calling party. That is, the user of the terminating terminal can determine whether to accept the call before responding to the ringing signal of the terminating terminal. As described above, according to the present invention, it is possible to easily protect the receiving side against a call connection request by the one-sided calling from the one-sided calling side, and the living right of the called side is not violated. It is possible to provide a superior telephone exchange system.

Furthermore, according to the present invention, since the subscriber information storage means is provided in the local exchange, the following remarkable effects are obtained as compared with the case where the subscriber information storage means is provided in the other exchange. . . Since the subscriber information storage means only needs to store the subscriber information belonging to the local exchange, it is not necessary to store the subscriber information of the entire system, so that the storage capacity can be simplified. . One subscriber information is stored only in the subscriber information storage means of the local exchange to which it belongs. Therefore, when adding or changing subscriber information,
Convenience can be improved because only one subscriber information storage means needs to be treated instead of the subscriber information storage means of the entire system. . As is clear from FIG. 1, there is no need to improve the conventional calling terminal.
On the other hand, the number of exchanges at other stations is far smaller than that of the originating terminal. Therefore, it is easy to modify the originating exchange. Therefore, introduction to existing telephone equipment is extremely easy.
