Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a storage service system for audio signals, etc. in a communication system, and more specifically,
This invention relates to an automatic calling system in which a called party who has received stored voice information can easily contact a caller.

[Background of the invention]

With the voice storage service, voice messages can be delivered and retrieved from the voice mail box, but the recipient must disconnect once after receiving the voice storage service.
Confirmation is then performed through a normal telephone connection by dialing the caller's address. According to this method, the operation is not only time-consuming but also troublesome.

As an example of this type of voice storage service system, as shown in Japanese Patent Publication No. 42-16452, there is a system that describes a means for storing a sender's message and delivering it to a recipient.

With this voice storage service method, voice messages can be delivered and retrieved from the voice mail box, but if the recipient has any questions or concerns about the content, they can use the voice storage service. Afterward, the caller must be disconnected and then dialed to confirm the caller's address using a normal telephone connection, which is a time-consuming and troublesome operation.

[Purpose of the invention]

The present invention has been made in view of the problems in the prior art described above, and improves functionality so that the operation is simpler and the called party who has received the stored voice information can easily contact the caller. The purpose is to achieve this goal.

[Summary of the invention]

A feature of the present invention is that the recipient who receives a message from the sender has doubts about the content of the message.
On the contrary, the system uses a system that calls the person who sent the message. That is, it has a plurality of voice terminals, a switch, and a voice information storage device, and the voice information transmitted from voice terminal A is stored in the voice information storage device, and the stored voice information is sent to another voice terminal B through the switch. In the automatic call method in the voice storage service system distributed through the voice terminal, the voice terminal has a specific operation code input function,
The voice information storage device has a specific operation code reception function, analysis function, and transmission function, and the exchange has a connection function between voice terminals A and B based on the transmission function of the voice information storage device. After receiving the distribution of the stored voice information, B inputs a specific operation code, the voice information storage device receives and analyzes this, transmits the analysis information to the exchange, and the exchange calls voice terminal A. The point is that it is connected to audio terminal B.

In a preferred embodiment of the present invention, an identifier (number) is assigned to each piece of stored voice information, and the number is associated with the caller's dial number. The point is that it is possible to connect and make a call by simply inputting an identifier by dialing, etc., without having to look up and dial the caller's dial number.

[Embodiments of the invention]

An example in which the present invention is applied to a message delivery service of voice service will be described below.

Figure 1 is a diagram of the relay system, and shows the voice terminal A.
1, A2 and B are connected to a voice information storage device 2 (hereinafter referred to as VSE) via an exchange 1.

Next, audio terminals A1 and A2 each receive terminal B
The case where a voice message addressed to the destination is stored in the VSE 2 will be explained with reference to a specific circuit diagram of the voice information storage device shown in FIG.

In Figure 2, 3 is the central processing unit (CC
), 4 is a communication path control device, 5 is a network, 6 is a control device, 7 is a voice information storage unit (hereinafter referred to as VSU), 8 is a conversion circuit (hereinafter referred to as MEM), 9 is a signal transmission/reception device , 10 is a signal line, 1
1 is a communication path.

In FIGS. 1 and 2, a connection request from the exchange 1 is received by the CC 3 via the signal source 10 and the signal transmitting/receiving device 9 in FIG. It is set by driving the control device 4, the VSU 7 is connected, and a communication path between the audio terminals A1, A2 and the VSU 7 is set here.

The control device 6 controls the VSU based on the command from the CC3.
7 and stores messages from terminals A1 and A2 in VSU7. Since the details of the storage technology exist as prior art, a detailed description thereof will be omitted here.

Note that when CC3 stores messages from voice terminals A1 and A2, it assigns a message number i as a message identifier to each message, and indicates the correspondence with the dial numbers of voice terminals A1 and A2.
Set to MEM8. This conversion circuit can be easily realized on a storage device.

FIG. 3 shows a case where the correspondence is configured as a conversion table A on the storage device.
Similarly, the dial number A1 is stored in the memory area indexed at the relative position 21 corresponding to the message number from the dial number A1 to the dial number A2.
A dial number A2 is set at a relative position 22 corresponding to the message number from. And VSE2
outputs the above message to voice terminal B via exchange 1.

In this way, when the VSE2 finishes sending the message, it sends the automatic call acceptance message b shown in FIG.
The voice terminal B is asked whether to connect to the sender A1 or A2 of the message, or both. When terminal B desires a connection, it dials the corresponding message number 3.
Disconnect if connection is not required. Upon receiving message number 3, VSE converts the conversion table shown in Figure 3 to relative position 2 corresponding to message number A1 or A2.
By indexing with 1 or 22, it is converted to a dial number of A1 or A2. In the case of both A1 and A2, one of them first dials A1's dial number as the automatic calling address signal d in Figure 4.
and send it to the exchange. The exchange sets up a line connecting terminal A1 to terminal B, sends a paging signal e to terminal A1, and starts a paging operation. Terminal A1
If responds by sending a response signal f, then
You can talk to terminal B (g).

When the call ends, terminal A1 sends a disconnection signal h to the exchange, and the exchange disconnects the line of terminal A1 while keeping the line of terminal B on hold, and transmits the disconnection signal i to VSE.
Send to 2. Next, in order to make a call to A2, VSE2 sends an automatic calling address signal j carrying the previously obtained dial number of A2 to the exchange. As in the case of A1, terminals A2 and B conduct a conversation, and when the conversation ends, VSE2 receives a disconnection signal o. VSE2 determines that there are no more terminals to connect to terminal B, and sends a termination signal p to the exchange, which also releases the line of terminal B. VSE2 sends a termination message q to terminal B, informing that terminal B has terminated the automatic call connection to all terminals desired by terminal B, and terminates the voice storage service.

In the above embodiment, as shown in FIG. 1, the voice terminals A1 and A2 and the voice terminal B are in the same exchange, or as shown in FIG. Even when the exchange 1' accommodating the voice terminals A1 and A2 is different, the exchange 1
While voice terminal B's line is on hold, voice terminal A
The method for setting up lines with A1 and A2 is the same.

Furthermore, the message number can be entered using existing technology, whether by using a pushphone or by voice recognition.

〔Effect of the invention〕

As is clear from the above embodiments, according to the present invention, a service recipient who receives a voice message stored by a voice storage service dials the dial number of the person who sent the message. You can automatically talk to the people you have saved by simply entering their message number without having to do anything, and there is no need to use a telephone line to confirm each time, which is the advantage of reducing operation time. .
