Abstract

PURPOSE:To inform assuredly the state of control for incoming to a telephone, by generating and transmitting a prescribed incoming control to the corresponding telephone from a sound informing device based on the incoming control information on the corresponding telephone given from a processor. CONSTITUTION:A telephone 1 is connected to a position A of an outgoing line of a switch network 2 which stores an output terminal of the corresponding one of plural channels of a sound generating device 7 via the network 2. The corresponding data is read out of a storage device 5 via a common bus 6, and the data of the position A is added the read-out data to obtain the incoming control informing information. This information is fed to the device 7 via the bus 6. The device receives each data to synthesize or edit the sound of information to be produced on the basis of the received data and at the same time transmits the sound of information to the output terminal corresponding to the position A. Then this informing sound reaches the telephone 1 via the network 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to telephone exchanges when the telephones housed therein are in various incoming call restriction states.

This invention relates to an incoming call restriction notification method for notifying the subscriber of the status.

Conventional incoming call restriction notification methods generally allow the subscriber whose telephone is in the incoming call restriction state to hear a special tone for notification of incoming call restriction, which is different from the normal dial tone, when the subscriber makes a call. It was intended to notify the incoming call restriction status.

This method is effective when there are only a few types of incoming call convenience services available to the subscriber. For example, if the only type of incoming call restriction service is a call forwarding service, calls using that phone may be effective. By hearing the special dial tone, the subscriber can immediately know that the telephone is in the incoming call transfer state, and can therefore make an appropriate call.

However, when there are many types of incoming call convenience services, even if it is possible to know that the service is in some kind of incoming call restriction state, it is not possible to specify which incoming call restriction state the service is in.

On the other hand, if the number of types of notification signal tones is increased, it will be complicated and uncertain for subscribers to distinguish between them, which will be impractical, and the serviceability will also deteriorate.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a call restriction notification system with good serviceability that can reliably notify the incoming call restriction state of a telephone.

A feature of the present invention is that, when a notification request signal is sent from a telephone in a call-restricted state or at a predetermined time, the telephone A connection is made between the telephone and the voice notification device, and the voice notification device generates and sends a predetermined call restriction notification sound to the telephone according to incoming call restriction notification information for the phone from the processor. It is in the incoming call restriction notification method.

The voice notification device is configured to include a memory for storing required incoming call restriction state data, and also allows standardization and simplification of its software.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a relay system diagram of one embodiment of the incoming call restriction notification system according to the present invention, and FIG. 2 is a relay system diagram of another embodiment.

Here, 1 is a telephone set in a call restriction state, 2 is a switch network of a telephone exchange, 3 is a doujin output device,
4 is the same processor, 5 is the same storage device, 6 is the same common bus, 6A is the bus related to the voice notification device, 7 is the same voice generating device, 8 is the same memory controller, 9 is the same memory It is.

First, the embodiment shown in FIG. 1 will be explained.

It is assumed that telephone 1 is receiving some kind of incoming call restriction service, and in order for the subscriber to know his/her incoming call restriction status,
When a predetermined specific dial signal is issued from the telephone as the notification request signal, the specific dial signal is received by the processor 4 via the common bus 6, as is known in the art.

The processor 4 analyzes the received digits and sends the phone 1
After identifying that the request is for notification of incoming call restriction status, the telephone 1 is connected via the switch network 2 to the outgoing line of the switch network 2 that accommodates the output terminal of the applicable dual-control channel of the voice generator 7. Connect to position A.

In addition, since the incoming call restriction state data of each telephone housed in the exchange is stored in the storage device 5, the data is read from the storage device 5 via the common bus 6 and added to the above-mentioned outgoing line position A. Data (notification connection data) is added to make incoming call restriction notification information, and the information is sent to the voice generating device 7 via the common bus 6.

The voice generating device 7 receives the above data, synthesizes or edits the notification voice to be generated based on the data, and sends it to the output terminal corresponding to the outgoing line position A.

This notification voice reaches the telephone set 1 via the switch network 2 and is heard and confirmed by the subscriber, and its contents are as follows, for example.

"Incoming calls to this phone will only be accepted from 8pm to 8am.
You will be transferred to number X. A station operator will be available from 8 a.m. to noon. be careful. Next, the embodiment shown in FIG. 2 will be described.

In this embodiment, all the incoming call barring state data regarding each telephone is stored in the memory 9, and as described above, when the processor 8 receives a request for notification of the incoming call barring state, the processor 8 controls the telephone 1 in the same manner as described above. After connecting to the outgoing line position A, the notification connection data,
That is, it is only necessary to send the telephone number of the telephone 1 and the data of the outgoing line position A to the memory controller 8.

When the memory controller 8 receives these data,
The incoming call restriction state data for the notification voice to be sent to the telephone 1 is read from the memory 9 via the bus 6A, and transferred to the voice generator 7.

The voice generating device 7 operates in the same manner as in the embodiment shown in FIG. 1, and the incoming call restriction notification is issued in the same manner.

In this way, in this embodiment, the memory controller 8. is dedicated to the incoming call restriction notification. Although the memory 9 is required, there is no need to use the storage device 5 of the exchange, so there is no need to consider the memory capacity for incoming call restriction notifications, and the software of the processor 4 is also simplified as described above. can be converted into

In addition to receiving notification requests from subscribers as explained above, incoming call restriction notifications can be issued by automatically calling the telephone 1 from the exchange at a specific time (for example, at a predetermined time on a specific day of the week). When responding, it is also possible to make a call repeatedly at predetermined time intervals to issue a predetermined incoming call restriction notification.

That is, the processor 4 uses its software to
At the time applied for and registered by the subscriber, a ringing signal is sent to the telephone 1 using a known method, and if the telephone responds, the connection is changed to the voice generating device 7 in the same manner as described above. to notify you of incoming call restriction.

This can be done under subscriber control, or it can also be done by inputting a command from the input/output device 3 upon request from the subscriber.

As described in detail above, according to the present invention, it is possible to provide a reliable incoming call restriction notification service to subscribers, so that subscribers can accurately understand their own incoming call restriction status and become confused about calls. This has a significant effect on improving the service quality for subscribers, such as eliminating the occurrence of problems.
