Abstract

PURPOSE:To prevent an undesired call of a subscriber or a call to which the answer is impossible by recording the information showing incapability for automatic transmission of a message to a control memory of a sound storing device in response to the receiving subscriber. CONSTITUTION:When a subscriber B, for example, does not want to receive a message from a sound storing device VMS, the subscriber B sends the control information to stop automatical transmission of message from the VMS as well as its own number to the VMS. This control information is received by a circuit controller LC1 and transferred to a CPU. In addition, the information showing incapability of automatic tansmission of message is set at a minor region corresponding to the subscriber B of a control memory CTLMN. As a result, the CPU checks the contents of the minor region of the message transmission control information corresponding to the subscriber on the memory CTLMN storing the information on the subscriber B in case a message is sent to the subscriber B from a subscriber A, for example, via the VMS.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a message transmission control system, and more specifically, to a method for automatically transmitting messages transmitted from a voice storage device attached to a telephone exchange by a subscriber receiving the messages. The present invention relates to a message sending control system that makes it possible to stop and then release the stop.

Prior Art and Problems Conventionally, in a voice storage device that stores a message to a specified subscriber and later transmits and receives the message to the subscriber, the voice storage device periodically sends messages to the specified subscriber. If the subscriber answers, a message addressed to the subscriber is sent, but if the subscriber does not respond when the subscriber is called, the call is stopped after a certain period of time; The call is made again in the next cycle. This call continues until the subscriber answers or until the maximum number of retries allowed by the voice storage device expires.

According to the above-mentioned conventional technology, the above-mentioned call is made regardless of the intention of the above-mentioned receiving subscriber who should receive the message. It is cumbersome to answer the call, and if the receiving subscriber is absent or unavailable, the voice storage device may repeat an invalid call, resulting in unnecessary waste on the voice storage device and the switch. The disadvantage was that it placed a heavy load on the machine.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned drawbacks of conventional voice storage devices that are used in addition to telephone exchanges to temporarily store messages and later automatically transmit them to designated receiving subscribers. The purpose of this system is to send control information to the voice storage device in advance from a subscriber who is expected to receive the information, and to prevent calls from the voice storage device that the subscriber does not wish to receive or calls that cannot be answered due to the absence of the subscriber. do.

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

FIG. 1 is a block diagram showing the connection configuration of an audio storage device embodying the present invention, and FIG. 2 is a block diagram showing the control memory CTLM of FIG.
It is a figure showing the composition of M.

In FIG. 1, EX is a telephone exchange, A and B are subscribers with telephones accommodated in the telephone exchange EX, and VMS
are voice storage devices, Ll, L2., which are attached to the telephone exchange EX. L, is a line connecting the two, and in the voice storage device VMS, LCl.

LC2r LCa are the lines Ll r L2 +
The line control device provided in Ll, NW is a communication path network device, cPU is a processing device, MM is a main memo IJ that works together with the processing device CPU, and CTLMM is a control that stores message sending control information corresponding to subscribers. Memo') Ml r
Mtr MB is a large capacity memo I in the voice message storage layer.
J and S are signal receiving and distributing devices, and G is a guidance sending device.

Next, in FIG. 1, subscriber A makes a call, calls the voice storage device VMSi, and stores the message there.
Furthermore, a case where the message is automatically sent to subscriber B will be explained.

Subscriber A makes a call and calls the voice storage device VMS vi-number? Dial. Subscriber A is sent from the exchange EX to the voice storage device VMS via a vacant line, for example Ll.
is connected to the line controller LCI. Line control device LC
, detects the incoming call and notifies the processing unit CPU of the incoming call of the signal receiving and distributing device S.

As a result, the processing unit CPU controls the guidance sending unit iG and sends the necessary guidance to the originating subscriber A via the line control units LC and 'ii. The guidance sending device G has an audio memory that stores various types of guidance information, reads the necessary guidance information according to instructions from the processing device CPU, converts it into audio form, and transmits it as an audio signal. Send to subscriber A. In the above case, information to the effect of "Please notify subscriber A of the desired service" is sent as guidance. When originating subscriber A desires a service to send a message to subscriber B,
In response to the above guidance, information corresponding to this service is sent, for example, by dialing digits.

The processing unit CPU receives this information via the line control unit LC1t, learns the type of service desired by subscriber A, and sends guidance on what kind of information to send in order to provide this service type. Subscriber A follows the guidance,
The calling subscriber number (subscriber A's own number), the called subscriber number (for example, subscriber B's number), etc. are sent. Upon receiving such information, the processing unit CPU connects the line L1 to a free large capacity memory, for example Ml, via the communication path network device NWf.
Connect to. Then, guidance is sent to start sending the message. Here, a call sent from subscriber A travels through a line, passes through one communication path network device NW, reaches large capacity memory M1, and is stored there as a message.

The control memo IJ CTLMM is provided with a memory area for storing message control information corresponding to the receiving subscriber.

In FIG. 2, subarea F is message sending control information corresponding to the receiving subscriber, and has information indicating whether automatic message sending is possible or not. Further, the small area C is an area where the time at which the automatic transmission stop is to be canceled is set as necessary, and if this is set, the small area F is rewritten to the automatic transmission time at the specified time.

The processing unit CPU is activated periodically, reads the message sending control information corresponding to subscriber B who receives the accumulated messages, and if it is in the automatic sending state, selects an available line, for example L2, and controls the line. A call is made to the exchange EX via the device LC2t-, sending the telephone number of subscriber B, and calling subscriber B via the exchange EXft.

If subscriber B responds, this is detected by the line control device LC2 via the exchange EX'f, and the processing device C is sent as described above.
After sending guidance via PU i and informing that messages from subscriber A have been accumulated and will be sent,
Controls the communication path network device NW to connect the line L2 and the large capacity memory M1 in which messages are stored, and connects the line Lge
A message is sent to subscriber B via the subscriber.

In the above case, if there is no response even after calling the receiving subscriber B for a certain period of time, the calling to that subscriber is stopped.

The processing unit CPU periodically repeats the above processing, and calls the receiving subscribers who have not responded again in the next cycle. This operation continues until the receiving subscriber responds or the maximum number of connection attempts allowed by the voice storage device VMS is completed.

Now, for some reason, subscriber B, for example, leaves the telephone or has something urgent to do,
If you do not want to receive messages from the voice storage device VMs, by notifying the voice storage device VMS,
It is possible to prevent the message from being sent at the will of the subscriber on the receiving side.

Taking subscriber B as an example, subscriber B makes a call and dials a number for calling the voice storage device VMS in the same manner as described above. The telephone of subscriber B is connected to the line control unit LCI of the voice storage unit VMS via the exchange υ and a free line, for example Ll.

In the same way as when the subscriber saver calls up the voice storage device VMS'i, the desired request is made from the guidance sending device G.
(Guidance will be sent to inform you of the services available.)

In this case, subscriber B requests a service fee to stop messages being automatically sent to subscriber B from the voice storage device VMS, so in response to the above guidance, subscriber , control information for stopping the automatic sending of messages from the voice storage device VMS, and time information for canceling the stop if necessary.

This information is received by the line control device LCI of the line L1, and transferred to the processing device CPU via the signal reception and distribution device S. Furthermore, subscriber B of the control memory CTLMM
In the subarea F of the message sending control information corresponding to the message sending control information, information indicating that automatic message sending is not possible is set, and the stop release time is written in the subarea C in response to a request.

In this way, the message sending control information subarea F in the fllJ memory CTLMM corresponding to subscribers who do not wish to have messages automatically sent from the voice storage device VMS.
Since information is set to disable automatic message sending, for example, from subscriber A to voice storage device VM as described above.
When sending a message to subscriber B via S Th, the processing unit CPU of the voice storage device VMS stores the message transmission control information subarea F corresponding to the subscriber in the control memory CTLMM that stores information about the receiving subscriber B. The contents are all inspected, and it is determined whether the black-spot subscriber B can receive the automatic transmission of the message, and the transmission of the message is performed or stopped.

If time information is stored in the sub-area C, automatic sending of messages can be stopped before the time has elapsed, and messages can be automatically sent after the time has elapsed, according to the time information.

Note that the subscriber who has performed the process of stopping the automatic transmission of messages can cancel the automatic transmission suspension. In this case too, the subscriber, for example B, dials the number for the voice storage device VMS on his telephone. For example, when the line control device LC3 is reached via the line Lsvil-, and the guidance sending device G receives a guidance requesting notification of the desired service in the same way as described above, the information instructing to cancel the automatic message sending stop and the own Dial the phone number. This dialed information line control device LCa
Based on this, the information in the subarea F of the memory transmission control information corresponding to subscriber B in the control memory CTLMM is changed to information indicating transmission permission.

The present invention is not limited to the above embodiments, and various modifications are possible.

Effects of the Invention Conventionally, this type of service has been provided to telephone exchanges, which temporarily stores messages sent from calling subscribers and their receiving subscriber numbers, and then automatically sends the messages to receiving subscribers at a later date. In the provided voice storage device, the automatic transmission of messages to the receiving subscriber is controlled only by the intention of the calling subscriber, and the receiving subscriber cannot control it, and it may be troublesome for the receiving subscriber to respond. There were also cases where the person was not present at the telephone and was unable to answer. However, according to the present invention, it is possible to stop and cancel the automatic transmission of messages from the voice storage device by operating the telephone according to the intention of the receiving subscriber. This has the effect of improving serviceability, reducing invalid calls, and reducing wasteful load on the exchange.
