Abstract

PURPOSE:To reduce communication cost, to improve operability and to store a read message by applying a remote reading command by inter-user information to be transmitted to the D channel of an ISDN network. CONSTITUTION:An incoming message remote reading command and an incoming message are transmitted by means of the inter-user information to be transmitted through the D channel of the ISDN network together with a call control message to be transmitted between both telephone sets at the time of setting up a call or releasing the disconnection of the call. Since all necessary information can be transmitted/received in the prestage (at the time of controlling the setting of the call) or the post stage (at the time of controlling the release of call disconnection) without setting up the call, the incoming message can be transferred within an extremely short time. Thus, the communication cost can be drastically reduced.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention utilizes the inter-user information transmission function of telephone devices connected to an ISDN network to transmit an incoming message to one telephone device to another telephone device. This invention relates to a remote reading method for incoming messages.

[Conventional technology]

Conventionally, methods for remotely reading incoming messages from one telephone device from another telephone device include a remote listening method for incoming messages in an answering machine system and a remote reading method for incoming messages in PC communication. It is being

[Problems to be Solved by the Invention] In all of the above conventional systems, the telephone device is connected to an analog network, and remote listening or remote reading takes a long time, so the telephone network is used for a long time. Therefore, there is a problem that communication costs increase.

Furthermore, in the answering machine system, incoming messages are voice messages, so especially if the incoming message is long, it may be necessary to listen to it many times, further increasing communication costs.

Furthermore, in personal computer communication, since a personal computer is usually a device used for multiple purposes, there is a problem in that it is complicated to operate.

The present invention is proposed in order to solve the above-mentioned problems, and has low communication cost, good operability, and allows reading out messages to be saved (that is, messages can be read out in text format). ) The objective is to provide a remote reading method for incoming messages.

[Means to solve the problem]

In recent years, the digitalization of telephone line networks has been put into practical use, and the so-called IS
This led to the construction of DNIA. The present invention is directed to this ISD
The above problem is solved using the N network, and the above I
Messages can be sent to other telephone devices using information between users that can be transmitted together with call control messages that are transmitted between telephone devices connected to the SDN network when a call is set up or when a call is released. Give remote read instructions,
The other telephone device that receives this instruction uses the inter-user information to transmit the incoming message stored therein to the telephone device that gave the instruction via the ISDN network.

(Function) The transmission of the incoming message from the telephone device in which the incoming message is stored to the telephone device on which the remote reading operation is performed is instantaneously carried out via the D channel of the ISDN network, so that the incoming message can be transmitted in a short communication time. Transfer is possible, and communication costs are extremely low.

In addition, when reading an incoming message remotely, all you have to do is call the other party's telephone device and then perform an extremely simple operation (pressing the remote read button and sending the PIN number). The transfer occurs and is visually displayed so that repeated access to the other party's telephone equipment is not required.

As shown in FIG. 4, the inter-user information memory UM includes a remote read flag area RF, a password area SNO, a message number area MNO5, an erase flag area CLF,
It consists of an incoming date and time area ITM, a calling ID area SID, and a message area MSG.

As shown in FIG. 5, the incoming message save memory SVM is designed to store multiple messages.
Each message storage area Ml, M2. . . . are each provided with an area for storing the date and time of incoming call, 1 caller number (caller ID), and message content.

Next, the operation will be explained with reference to FIGS. 2 and 3.

As shown in Figure 2, terminal A and terminal B are connected to the ISDN network, and terminal A and terminal B are the telephone devices shown in Figure 1, respectively, with terminal A being the reading side and terminal B being the reading side. It is assumed that the terminal is the one to be read. That is, by giving a remote read instruction to terminal A, the incoming message stored in the incoming message save memory SVM of terminal B is read by terminal A via the ISDN network.

When a message arrives at terminal B, the message is stored in the incoming message save memory S of terminal B in the order of arrival.
Stored in VM. This operation will not be described in detail since it is not directly related to the present invention.

First, the remote reading operation of the N011 message will be explained.

In order to remotely read out the incoming message recorded on terminal B, perform a remote read operation on terminal A (press the remote read key 7 and send the recipient's number and PIN using the dial 6). When this is done, the CPU 2 of the terminal A reads the inter-user information memory U in the memory 5.
Set inter-user information for remote reading in M. That is, a flag is set in the remote read flag area RF, the PIN entered by the dial 6 is stored in the PIN area SNO, and the message number area MN is set.
Since O is set to "OO", no message number is specified at the time of initial reading. ), and sets "0" in the erase flag area CLF (at the time of first reading, it is set so that even if the erase key 9 is pressed, it will have no effect).

Next, the CPU 2 of terminal A connects D via S interface 1.
A call control message (call setup message) for call setup is sent to the ISDN network using the channel. The ISDN network connects terminal A and terminal B using this call setup message, and also sends the call setup message to terminal B.
A call control message (call setup acceptance message) is sent to confirm that the call setup has been accepted.

As described above, when setting up a call, terminal A is
There is a call control message transmitted from the terminal A to the terminal A, and the inter-user information set in the inter-user information memory UM of the terminal A is in the form shown in FIG. 3(A) together with the above call control message (call setting message). Sent to the terminal.

Note that the user-to-user information sent to terminal B here is the activation information of the remote reading service, and therefore does not include incoming date and time data, sender ID data, and message content data. Furthermore, the message number being "00" indicates that the activation is the first activation.

Upon receiving the above user-to-user information, in terminal B, the CPU 2 reads it via the S interface 1, first checks the remote read flag for the user-to-user information, and if this is "0", the general When it is "1", the call is not set up using a call setup message, and the response is rejected from the perspective of general incoming calls, and a call control message for response rejection is sent to the ISDN network. .

This call control message has the same form as a call control message (release completion message) indicating completion of release, and is shown as a release completion message in FIG.

The inter-user information sent from terminal B to terminal A is sent together with the release completion message when the release completion message is sent.

That is, in terminal B, the CPU 2 confirms that the remote read flag of the user information from terminal A is "1", and then stores the password in the user information and the password memory SNM in the memory 5. The stored password is checked, and if the two do not match, the user-to-user information shown in FIG. 3(B) is sent to the ISDN network along with the release completion message. The inter-user information shown in Figure 3 (B) includes the remote read flag 'IJ', data rFFFFJ indicating that the R certificate number is incorrect, and data indicating the message number '00' (data indicating a response to the first activation). This information consists of

In the ISDN network, upon receiving the release completion message from terminal B, it sends a call control message (disconnection message) indicating line disconnection to terminal A, and also transfers the inter-user information from terminal B, including it in the disconnection message. .

Thereafter, two call control messages (a release message and a release completion message) were exchanged between terminal A and the ISDN network, and terminal A was released from the ISDN network, and the terminal A also sent the above-mentioned disconnection message. The CPU 2 reads the above-mentioned user-to-user information, displays an incorrect password on the message display section 8, and the series of controls ends.

If the PIN sent from terminal A matches the PIN stored in terminal B's PIN memory SNM, then terminal B
CPU 2 identifies the message number in the inter-user information sent from terminal A, and in this case, since the message number is "00", it is stored in the incoming message save memory SVM of terminal B. Total number of messages (
Total number of incoming messages received and stored up to that point)
is read from the message total number memory MTM and stored in the message number area MNO of the inter-user information memory UM. At this time, in order to represent that the information sent by the message number of user information is the total number of messages, the most significant bit of the message number area MNO is set as "IJ".
U2 refers to the message number memory NM, and in this case,
Since "ol" is stored in the message number memory NM (indicating that this is the first message read), the incoming message save memory SVM
The reception date and time, caller number (caller ID), and message contents of the message stored in No. 1 message storage area M1 are respectively stored in the reception date and time area ITM and caller ID area S ID of the inter-user information memory UM. and transfer it to the message area MSG. In addition, "1" is set in the remote read flag area RF of the user-to-user information memory UM to indicate that the user-to-user information is based on a remote read request from terminal A, and the password area SNO is set in the remote read flag area RF. No data will be provided to prevent the PIN from being discovered by someone else.

As described above, the user-to-user information to be sent to terminal A is set in the user-to-user information memory UM of terminal B, and this information is released in the form shown in FIG. It is sent to the ISDN network together with a completion message. The ISDN network transmits the user-to-user information to terminal A along with a disconnection message in the same manner as described above.
and terminal A sends it to CP via S interface 1.
U2 reads the inter-user information from the terminal B. Next, the CPU 2 checks whether the most significant bit of the message number of the read inter-user information is "1" or not.
In this case, it is "1", so store (save) the total number of messages sent in the area of the message number for remote reading of the second and subsequent messages, and then display it in the message display section 8. No. 1 Displays the date and time of message reception, caller number (caller ID), and message content. At this time, the total number of messages may be displayed on the message display section 8.

In the above operation, the above-mentioned inter-user information is sent from the ISDN network to terminal A, and the information between the ISDN network and terminal A is transmitted.
Call control messages such as a disconnection message, a release message, and a release completion message are exchanged between terminal A and I
The release from the SDN network is the same as in the case where the passwords do not match.

Next, when the total number of messages stored in terminal B is 2 or more, the operation of sequentially reading out messages from No. 12 onwards on terminal A side will be explained.

No. 1 After reading the message, press the remote read key 7 on terminal A again. At this point, if the user wants to delete the No. 1 message that has already been read out from terminal B, the user presses the delete key 9. Further, as for the telephone number and password of the other party (terminal B), the numbers entered manually when reading out the No. 1 message are stored in terminal A, and there is no need to enter them again using the dial 6.

With the above operations, No.
, 2 message remote readout activation is set. That is, the remote read flag area RF is set to "1", and the password area is set to the above No.
, 1 The same PIN entered when reading the message is stored, and the message number area MNO contains No. 2.
"02" indicating the message is stored, the erasure flag area CLF is "0" or "1" (if the erasure key 9 is pressed, the carp is "1", otherwise it is "0"), and the incoming date and time area (ITM), the originating ID area SID, and the message area MSG are assumed to have no data.

The inter-user information set as above is No. 1.
As in the case of startup when reading a message, the message is sent from terminal A to terminal B via the D channel of the ISDN network together with a call setting message via the S interface 1 under the control of the CPU 2. The form of the inter-user information at this time is as shown in FIG. 3(D).

In terminal B, when the CPL 12 reads the above-mentioned user-to-user information via the S interface 1, the CPU 2 checks the remote reading flag, password, and message number for the above-mentioned user-to-user information, and in this case, sets the remote reading flag. is Ml (in the case of 'OJ, it is a general incoming call process), the PIN is correct (if it is incorrect, the process moves to the PIN mismatch operation in Figure 2 above), and the message number is Since it is not roOJ, next CPU2
Check the above-mentioned inter-user information deletion flag.

When the above inter-user information deletion flag sent from terminal A is "O", the CPU 2 of terminal B reads this and stores the No. 1 message sent to terminal A in the above operation as it is in the No. of the incoming message save memory SVM. ,
1 message storage area M1, and identifies that the message number of the above-mentioned inter-user information is "02", and stores it in NO12 of the above-mentioned incoming message save memory SVM.
Incoming date and time stored in message storage 197M2, outgoing I
D and the data indicating the message contents are stored in the incoming date and time area ITM of the inter-user information memory UM, and the sending ID area SID.
and message area MSG, and set the remote read flag area to [1] and the password area S.
NO is set to no data, the message number area is set to "02", and the erasure flag area CLF is set to "0".

The user-to-user information set in the user-to-user information memory UM as described above is sent from terminal B to the ISDN network together with a release completion message in the form shown in FIG. 3(E), and the ISDN network is disconnected. It is forwarded to terminal A along with the message.

In terminal A, the CPU 2 reads the above-mentioned inter-user information via the S interface 1, and since the deletion flag is "0", the CPU 2 displays N08 on the message display section 8.
2 Displays the date and time the message was received, caller ID, and message content.

Furthermore, when the deletion flag of the inter-user information sent from terminal A is "1", terminal B reads the deletion flag "1" from the CPU 2 and sets the number before the message number of the above-mentioned inter-user information. The corresponding message, in this case No. 1 message, is deleted from the No. 1 message storage area M1 of the incoming message save memory SVM, and the messages stored in the No. 2 message storage area M2 and later are deleted respectively. 8 in the message storage area of
make it move. As a result, No. 2 message will be changed to No.
, 1 message, and this new No. 1 message is transferred from the incoming message save memory SVM to the inter-user information memory IJ, similar to the operation when the above deletion flag is "0".
The inter-user information transmitted from terminal B to terminal A is configured.

At this time, the information between users is as shown in Figure 3 (F), the remote read flag is "1", the password is no data,
The message number is "01" (No. 1 message was deleted, so the No. 2 message sent this time is a new N number.
o, sent as one message. This allows terminal A to confirm that the previously sent message has been deleted. )
, the deletion flag is "1", the incoming date and time, caller ID, and message content are respectively the above new No. 1 message (old No.
2 messages).

This user-to-user information is transmitted from terminal B to ISD as described above.
It is sent to the ISDN network along with a release completion message.
The network forwards it to terminal A along with the disconnection message.

At terminal A, CPU 2 via S interface 1
When reads the above-mentioned inter-user information, the CPU 2 reads,
The message number of the relevant user-to-user information has become a new message number (in this case, it was "02" when sent from terminal A, but "01" when received on terminal A).
It becomes. ) and the deletion flag is "1", the value obtained by subtracting 1 from the message number and the total number of messages is saved, and the new number, date and time of arrival of the first message, caller ID, and message content are displayed in the message display section 8. to be displayed. This display allows the terminal A to sell the second message received and stored at the terminal A by 8. At this time, the total number of messages is displayed on the display section 8.
If the number of incoming messages remaining for terminal B is displayed on terminal A, terminal A can also know the remaining number of incoming messages sent to terminal B.

Messages No. 3 and later stored in terminal B can be read by terminal A by repeating the operations described above.

Furthermore, if there are no incoming messages recorded on terminal B and the total number of messages saved on terminal A reaches "0", if a remote reading operation of the incoming messages is performed from terminal A, Since the total number of messages is "0", the CPU 2 of terminal A
The call is terminated without setting up the call to the network.

Messages received on terminal B as described above are transferred to terminal A.
After reading out the information, when a termination operation is performed on terminal A, the CPU 2 performs termination processing and the series of remote readout control is terminated.

In the above embodiment, the remote read activation information sent from the read side terminal bundle A to the read side terminal is used together with the call control message for call setup, and the incoming message information sent from the terminal B to the terminal A. is an example in which call control messages for release completion and disconnection are sent to each other party.
In addition to the above, there are a number of other call control messages, such as call control messages for calling the called terminal. Since it is possible to transmit information between users, the above-mentioned remote readout activation information and incoming message information can be sent to the other party during any call control message transmission phase, as long as the transmission direction is not changed. be.

〔Effect of the invention〕

As explained above, the present invention provides user information that can be transmitted together with call control messages transmitted between telephone devices via the D channel of an ISDN network, for example, when setting up a call, when releasing a call, etc. This is a system that uses time information to transmit remote reading commands and incoming messages for incoming messages, without having to set up a call. Since all necessary information is exchanged during release control), incoming messages are transferred in an extremely short time, and communication costs are therefore extremely low.

In addition, the operation for remote reading requires only dialing the number and PIN of the other party's telephone device and then operating the remote reading button, and furthermore, reading the second and subsequent messages only requires operating the above button, making it easy to operate. Furthermore, since forwarded messages are visually displayed, there is little need to repeatedly access the other party's telephone device.
