Set a normal service for the caller to call the specified phone when making a call, and for caller B, transfer the call from the caller to the voice storage means by the transfer means, and store the message to the called party who is away An answering service is set, and registration is performed for the caller C by setting a transfer service for transferring a call from the caller to a telephone designated by the callee in advance.

When a call is received from a caller, the caller is identified by caller identification means 820. The service corresponding to the identified caller is recognized from the caller / service correspondence registration unit 822, and the service is implemented. By such an operation, an appropriate response can be set in advance for each caller by selecting a callee, and the exchange service can be used effectively.

[0005] As described above, the conventional answering machine notification system of the answering machine service is based on the case where a subscriber who is not answering a message keeps the answering machine service in a registered state for a certain period of time and receives an incoming call to a subscriber who is not answering. Then, the caller of the incoming call receives an exchange service such as listening to the message stored in the voice storage means, and recognizes that the other party of the call is absent.

That is, when a subscriber who requests the answering machine service receives an incoming call while answering,
This is a terminating control method in which a calling subscriber is notified of an absence by performing a switching service such as an answering machine service and a transfer service.

[0007]

A first problem in the above-mentioned conventional answering machine service is that a subscriber who registers the answering machine service notifies an arbitrary party of his / her absence in advance. There is no way to do this. That is, in the conventional answering machine service, even if there are a plurality of subscribers who want to immediately notify their own answering in the subscriber registering the answering machine service, the other party calls the subscriber registering the answering machine service. Until there was no notification of absence. Also,
There is also a method in which the user himself / herself makes a normal call to notify a plurality of other parties of absence, but this method cannot quickly notify a large number of subscribers of his / her absence.

As a second problem, a subscriber calls a subscriber who is registering the answering machine service, hears a message transmitted by the answering machine service, and recognizes that the other party is an answering machine. At this time, when a message for the subscriber who is away is recorded in the voice storage means,
There is a problem in that the user cannot talk to the subscriber who registers the answering machine service, and an extra call charge for recording a message is required.

[0009]

FIG. 4 is a diagram showing a processing flow in the system shown in FIG.

The subscriber terminal 1, called subscriber terminal 7, called subscriber terminal 8 and called subscriber terminal m in FIG. 4 are the same as those in FIG.

The answering service registration control program 13, the answering service notification control program 14, the answering service confirmation control program 15, and the answering service registration area 9 are provided in the main storage device 6.

The answering machine service registration control program 13 accepts a dialing of the answering machine service registration request from the subscriber terminal 1 and a response message. The dialing includes the telephone numbers of the called subscriber terminal 7, called subscriber terminal 8, and called subscriber terminal m of the destination to which the absence is to be notified.

The answering machine service registration control program 13 sets the answering machine service registering flag 911 indicating that the service is being executed as described above in the answering machine service registering area 9, and sets the telephone number of the called subscriber terminal for notifying the absence. Upon completion of storage and data saving such as the setting of the called subscriber terminal number information valid flag 912 indicating whether or not the absence has been notified for each called subscriber terminal that is to be notified of absence, the answering service notification control program 14 is activated. .

The answering machine service notification control program 14 repeats the registration of the answering machine notification by dialing from the subscriber terminal 1 at predetermined time intervals after a predetermined time elapses. Are periodically called to the called subscriber terminal 7, called subscriber terminal 8 and called subscriber terminal m, and when each called subscriber terminal responds to the call,
The response message recorded during the service registration request dialing from the subscriber terminal 1 is heard. In addition, data processing corresponding to the called subscriber terminal that responds and is stored in the answering machine service registration area 9 is performed. This data processing means that when the notification of the answering machine to the receiving subscriber terminal is completed, a flag corresponding to the answering-subscribed receiving subscriber terminal in the answering subscriber terminal number information valid flag 912 in the answering machine service registration area 9 Is set to 0 to register that the absence notification to the terminal has been completed.

When there is a dialing for confirming whether or not the answering notification from the subscriber terminal 1 to each receiving subscriber terminal has been completed, the answering service confirmation control program 15 causes the subscriber in the answering service registration area 9 to register. Terminal 1 corresponding area 91
If it is determined that the answering service registering flag 911 is set to 0 and that the answering notification has been completed for all the called subscriber terminals set to perform the answering notification, the subscriber is The terminal 1 is made to hear a tone indicating completion of all notifications. Also, the answering machine service registering flag 911 remains at 1, and it is identified that there is an unsubscribed or unanswered incoming subscriber terminal among the incoming subscriber terminals set to perform the answering notification. In this case, the telephone number of the called subscriber terminal whose notification of absence is not completed is notified to the subscriber terminal 1 by the voice storage means.

The answering machine service confirmation control program 15 receives the cancellation request dialing from the subscriber terminal 1 when there is an unsubscribed or unanswered incoming subscriber terminal, and registers the answering machine service registration. By setting the answering machine service registering flag 911 of the area 9 to 0, processing for canceling the answering machine service registration is also performed.

Further, the flow of processing in this system will be described in detail with reference to the flowcharts of FIGS. 5, 6, and 7.

The flowcharts of FIGS. 5, 6, and 7 show the processing procedures of the answering service registration control program 13, the answering service notification control program 14, and the answering service confirmation control program 15, respectively.

In FIG. 5, when a subscriber requesting an answering machine service requests a registration from the subscriber terminal 1 by an answering machine service registering dialing 10, the answering machine service registration control program 13 identifies the dialed answering machine service request identification. Dial 101, that is, # 56, followed by a delimiter dial + telephone number 102 of the called subscriber terminal 7 to be notified of absence, a delimiter dial +
The telephone number 103 of the called subscriber terminal 8 to be notified of absence;
Separating dial + incoming subscriber terminal m to be notified of absence
Is received (step S1).

Also, by setting the answering machine service registering flag 911 to 1 in the area 91 corresponding to the subscriber terminal 1 in the answering machine service registration area 9, it indicates that the answering machine service request has been accepted and is being executed. (Step S2).

Next, the number registration area 913 of the called subscriber terminal 7, the number registration area 914 of the called subscriber terminal 8 to be notified of the absence, and the number of the called subscriber terminal m to be notified of the absence of the called party. Each telephone number is saved in the number registration area 915, and the corresponding incoming subscriber terminal number information valid flag 912 is set to 1 (step S3).

When the subscriber terminal 1 receives the input termination identification dial 105 of the number of each receiving subscriber terminal to which the absence is to be notified, in this example, **, the subscriber terminal 1 is connected to the voice storage means, and the absence is recorded. The answering machine response message to be heard by the called subscriber terminal to be notified is received and recorded in the voice storage means (recording 106 in the voice storage means) (step S4).

At the end of recording the response message, the subscriber terminal 1
To answering service registration request end identification dial 10
7. In this example, when * # is received, the telephone number of the subscriber terminal 1 is transferred to the voice storage means and stored (step S5).

Finally, after the call with the subscriber terminal 1 is disconnected, the answering service notification control program 14 is activated, and the answering service registration control program 13 ends the processing (step S6).

Next, the flowchart of FIG. 6 will be described.

The answering service notification control program 14 sends the answering service registration dialing 1 from the subscriber terminal 1.
Until a predetermined time, for example, 24 hours, elapses after 0 is input, the receiving subscriber terminal 7 and the receiving subscriber terminal 8 are successively provided at predetermined time intervals, for example, every 5 minutes.
And periodically calls the called subscriber terminal m (step S
7). Each time one terminating subscriber terminal responds to a call that is periodically made to the terminating subscriber terminal set to give an absence notification, the subscriber terminal is connected to the voice storage means, and the subscriber is subscribed. The response message stored when the answering service registration dialing 10 is input from the user terminal 1 is heard (step S8). Of the called subscriber terminals that have responded to the call made by the answering machine service notification control program 14, the corresponding called subscriber terminal number information valid flag 912 is set to 0, and the answering machine has been notified. However, by leaving the value of the corresponding part of the receiving subscriber terminal information valid flag 912 at 1 for the non-responding receiving subscriber terminal, it is possible to identify that the notification of absence is not completed. (Steps S9 and S10). If the response message from the subscriber terminal 1 can be heard to all the incoming subscriber terminals set to perform the answering machine notification, the answering service registering flag 911 should be set to 0. The completion of the answering machine notification is registered as a result, and the execution registration of the answering machine service is terminated (step S12). If there is a subscriber terminal that has not responded, the answering machine service registering dialing 10 from the subscriber terminal 1 is performed. Until a certain period of time, in this example, 24 hours has passed, the value of the corresponding location of the called subscriber terminal number information valid flag 912 is kept at 1, and a call is repeatedly made to the subscriber terminal (step). S9,
Step S10).

Next, the flowchart of FIG. 7 will be described.

When the answering machine service notification completion confirmation dialing 11, that is, # 57, is input from the subscriber terminal 1, the answering machine service confirmation control program 15 accepts the request (step S14). The answering machine service confirmation control program 15 checks whether or not the dialing is for the answering machine service notification completion confirmation for inquiring whether or not the answering machine notification has been completed for all the called subscriber terminals set to perform the answering machine notification. Alternatively, if you set to perform the answering machine notification, but there is an unsubscribed or unanswered incoming subscriber terminal, the registration of the answering machine message will be terminated in the middle, Identification is performed (Step S15, Step S24).

If the dialing is neither of them, it is regarded as an erroneous dialing and a reorder tone or the like is heard (step S25).

The dialing 12 for canceling the answering machine service notification in the state where there is an unsubscribed or unanswered incoming subscriber terminal of the partial answering machine, ie, in this example, #
If # is received, the answering machine service notification control program 14 stops the answering service registration in order to stop calling all the unsubscribed or unanswered incoming subscriber terminals that are to be called again at regular intervals. The middle flag 911 is set to 0 to cancel the absence notification registration (step S27).

If the dialing is for confirming the answering machine service notification, the answering machine service registration area 9
Check the value of the answering machine service registering flag 911 indicating that the answering machine service request is accepted and being executed in the area 91 corresponding to the subscriber terminal 1 (steps S16 and S17).
Check if the answering service is being registered.

If it is not in the registration state, it is regarded as invalid dialing and a reorder tone or the like is heard (step S2).
5).

If it is in the registration state, the called subscriber terminal number information valid flag 912 corresponding to the subscriber terminal 1 is searched, and the location having a value of 1, that is, the destination subscriber terminal for which the notification of absence is not completed is extracted. (Step S18). If the values are all 0, it is considered that the absence notification has been completed for all the subscriber terminals that have been set to perform the absence notification, and the subscriber terminal 1 is given an absence to hear any tone. Notify that notification has been completed (step S2
6).

Incoming subscriber terminal information valid flag 912
Is searched, and if there is a place where the value is 1, the telephone numbers of all the receiving subscriber terminals for which notification has not been completed or not responding are stored in the number registration area 91 of the receiving subscriber terminal 7 to which the absence is to be notified.
3. Take out from the number registration area 914 of the called subscriber terminal 8 to which the absence is to be notified and the number registration area 915 of the called subscriber terminal m to which the absence is to be notified, and send it together with the telephone number of the subscriber terminal 1 to the voice storage means. (Step S
20).

Next, the subscriber terminal 1 is connected to the voice storage means, and the telephone numbers of all unanswered or unanswered subscriber terminals which have been converted into voice by the voice storage means are heard (step S21).

After the above-mentioned processing, a new dialing for canceling the notification of the answering machine service can be accepted from the subscriber terminal 1 (S22), and the dialing for cancellation (## in this example) is actually received. The answering service registering flag 911 is set in order to stop the calling of all the unsubscribed or unanswered called subscriber terminals.
Is set to 0 (step S27).

If the dialing is not for canceling the answering service notification, it is regarded as invalid dialing and the subscriber terminal 1 is made to hear a reorder tone or the like (step S25).

Regarding the method of calling each called subscriber terminal to which the absence is to be notified, in this example, if a given called subscriber terminal does not respond to the first call, the call is periodically transmitted within a certain period of time. , But a re-call to the called subscriber terminal may be performed only once.

[0058]

The subscriber requesting the answering machine service of the present invention makes a registration request from the subscriber terminal 1 by the answering machine service registering dialing 10, and is saved on the main storage device 6 by the answering machine service registration control program 13. On the basis of the received information, the answering machine service notification control program 14 makes a periodic call at a fixed time interval, thereby realizing automatic notification to a plurality of called subscriber terminals that want to be notified of the absence. Therefore, the subscriber who registers the answering machine service can immediately notify his / her absence without waiting for an incoming call from his / her plurality of called subscriber terminals to which he / she wants to be notified. Also, since the call to the called subscriber notified of the absence is an incoming call, the subscriber notified of the absence is not charged any call charges.
