Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice mail posting display system, and more particularly to a voice mail posting display system in a load program controlled time division switch.

Conventionally, to determine whether a mail has been sent to a subscriber capable of voice mail service, each subscriber dials a special mail retrieval number from a telephone to confirm the presence or absence of a message. However, in this system, the subscriber has to dial the special number at regular intervals or whenever he or she notices, which hinders the effective use of the voice mail service. Also,
You will not be able to retrieve your mail unless you perform the above special number operation, so if you forget this operation, the original purpose of voice mail service, convenience, and communication such as repeating messages due to the other party being absent or busy, etc. The drawback was that loss reduction was not achieved sufficiently.

SUMMARY OF THE INVENTION An object of the present invention is to provide a voice mail posting display method that eliminates the above-mentioned drawbacks by displaying the number of posted voice mails on the destination telephone to which the voice mail has been posted, so to speak, making it unnecessary to periodically check the mail box. .

The voice mail posting display method according to the present invention is provided in a program-controlled time division switch that provides a voice mail service, in which a telephone capable of voice mail service accommodated in the switch is provided with a display means for displaying the number of voice mail posts, and The exchange is characterized in that it includes a storage means for counting and storing the number of posts for each of the telephones, and displays the number of posts on the telephone that is the voice mail destination.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the voice mail posting display method of the present invention. In the same figure,
Multiple voice mail service capable subscribers (below)
TEL) 1A and ~1N are respectively accommodated in a time-division communication channel network (hereinafter NW) 3 via digital line circuits (hereinafter DLC) 2A and ~2N, and the NW 3 receives instructions from a central controller (hereinafter CC) 4. A predetermined link connection is made. The main memory device (hereinafter referred to as MM) 5 stores various information including voice mail count values for each TEL and execution programs, and read/write control of this information is performed by the CC
4 will do it. Also, voice mail device (hereinafter referred to as VMS) 7
consists of a magnetic disk device (hereinafter referred to as DSK) 70 that stores voice mail (message) from the TEL that posted the voice mail for each destination subscriber, and a control unit (hereinafter referred to as CNT) 71 that performs necessary control of the VMS 7. , the DSK 70 interfaces with the NW 3 and CC 4 via an interface circuit (hereinafter referred to as INT) 60, a PCM multiplex line (hereinafter referred to as L), an INT 61 and a control bus (hereinafter referred to as CB), respectively. Furthermore, the CC4 is the DLC2A, ~2N and INT61
to detect changes in the status of the TEL1A, ~1N and dialing number information, and to detect the dialing number information and the VMS7.
It also controls communication with. In addition, the above TEL1A, ~
1N is each equipped with a display circuit for digitally displaying the number of voice mails sent.

Next, the operation of this embodiment will be explained.

For example, when TEL1A goes off-hook, CC4 periodically scans DLC2A, so
Call information is detected from TEL 2A, a generally known call connection is made, and a calling register trunk (not shown) becomes ready to receive numeric information from TEL 1A via NW3. Then the TEL1
When A dials the predetermined voice mail access special number "X", the NW3
When the link between the DLC2A and the transmission register trunk is restored, the link between the DLC2A and the INT60 is set, and the CC4 sends a control signal (access signal) to the control bus CB and accesses the VMS7 via the INT61. The TEL 1A can communicate with the VMS 7 through a communication path via the DLC 2A, link, L, and INT 60. Next, the TEL1A is connected to the destination subscriber, for example, TEL1A.
When dialing the subscriber number n of 1N followed by a voice mail mailing special number, for example "#", the CC4 detects the special number "#" from the DLC2A and sends the CB,
Since the mailing notification signal is sent via INT61, the above
In VMS7, CNT71 is DSK70, the CNT71,
Connect with the INT60. Therefore, the above TEL1
The voice mail (message) from A is sent to the predetermined address of the DSK 70 (the
TEL1N compatible address).
Further, if the TEL 1A dials the subscriber number n, then the subscriber numbers b, c, ~ of other destination subscribers 1B, 1C, ~ (none of which are shown), and finally dials the special number "#". , said DSK
70 multiple destination subscribers TEL1N, 1B, 1
C. The same message can be stored at the same time in corresponding addresses (voice mail posting operation).
Note that the audio signal of the message is transferred in the L on a PCM multiplex basis of, for example, 2048 Mb/s.
After completing the above voice mail posting, call 1A above.
When on-hook, CC4 connects the above link, 〓
be released. On the other hand, the CNT 71 sends a voice mail storage end signal to the INT 61 and stores it. Next, the CC4 periodically scans the INT61 to obtain the voice mail storage completion signal and destination subscriber information (for example, the address information of the TEL1N).
is read out, and an address counting circuit (not shown, but as described later) corresponding to the address information is
) in MM5) and add "1" to the number of voice mails posted (hereinafter referred to simply as the number of mails) to DLC2N.
The DLC to be displayed on the TEL1N via
Control 2N. Other destination subscribers TEL1B,1
Similar operations are performed for C and ~ (voice mail posting operation).

Conversely, when the destination subscriber retrieves a voice mail, for example, when the TEL1N dials the voice mail retrieval special number "Y", the DLC2 is sent from the TEL1N in the same sequence as the voice mail posting operation described above.
N, Link, =, L, A call path to DSK70 is set up via INT60 and CNT71, and the corresponding TEL1
N listens to the message stored in the DSK 70. On the other hand, the CNT 71 stores the voice mail retrieval end signal of the TEL 1N in the INT 61, and the CC 4 restores the link,
The INT 61 is periodically scanned to read the voice mail retrieval end signal and the retrieved subscriber information, and the counting circuit corresponding to the subscriber information is subtracted by "1" to display the number of mails on the TEL 1N ( voice mail retrieval operation). In addition, when retrieving multiple voice mails, if the TEL1N dials the special number "Y" each time it listens to a message,
The voice mail retrieval operation described above is repeated. The same applies to the other take-out subscribers TEL1B, 1C, and so on. If it is necessary to save the voice mail, the voice mail retrieval subscriber dials the voice mail storage special number "Z" and can listen to the message in the same sequence as the voice mail retrieval operation described above. Since the voice mail retrieval end signal is not set in the INT61, the CC4 does not subtract "1" from the counting circuit, and the display of the number of mails sent by the retrieving subscriber remains unchanged.

In this embodiment, the voice mail access special number "X", retrieval special number "Y", storage special number "Z", and mailing special number "#" can be any numerical code or special code that can be determined in advance, as long as they are different from each other. Needless to say, it's a good thing.

Next, FIG. 2 is a diagram showing an example of the bit configuration of the counting circuit section of the main memory device in FIG. 1. In the figure, the counting circuit section that stores the number of mails for each subscriber location information EN _a , EN _b , ~EN _o stores 1 byte (8 bits) of information per subscriber, that is, a maximum of 256
You can memorize the count of emails. As mentioned above, CC4 (shown in Figure 1) adds and subtracts "1" each time a subscriber posts or retrieves a voice mail, and collects the subscriber's accommodation location information.
Control is performed to rewrite the count value of the EN-compatible counting circuit section, and to read out the count value and display it to the subscriber.

Note that this configuration example does not limit the application of the present invention. That is, the number of bits per subscriber may be other than 8 bits.

As is clear from the above description, according to the voice mail posting display method of the present invention, the number of voice mail postings is always displayed on a telephone capable of voice mail service. Therefore, the subscriber only needs to retrieve voice mail by operating a special number when there is a large accumulation of voice mail, which not only fully achieves the original purpose of voice mail services, such as convenience and reducing communication loss. This has the effect of improving the ease of operation.
