As shown in FIG. 5, the incoming message save memory SVM stores a plurality of messages.
Each of the storage areas M1.M2,... Of each message is provided with an area for storing an incoming date and time, a caller ID (calling ID), and a message content.

 Next, the operation will be described with reference to FIGS.

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

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

First, the remote read operation of the No. 1 message will be described.

Remote reading operation at terminal A in order to remotely read the incoming message recorded at terminal B (operation of pressing remote reading key 7 and sending out the number and password of the telephone device to be read out through dial 6) Then, the CPU 2 of the terminal A sets the user information for remote reading in the user information memory UM in the memory 5. That is, the remote read flag area
The RF is flagged, the password input by the dial 6 is stored in the password number area SNO, and "00" is set in the message number area NMO (the message number is not specified at the first reading). The flag area CLF is set to “0” (at the time of the first reading, it is set to be invalid even if the erase key 9 is temporarily pressed).

Next, the CPU 2 of the terminal A sends a call control message (call setting message) for call setting to the ISDN network via the D channel via the S interface 1. The ISDN network connects the terminal A and the terminal B with the call setup message, and sends a call setup message to the terminal B and a call control message (call setup acceptance) for confirming that the call setup has been accepted to the terminal A. Message).

As described above, at the time of call setup, there is a call control message transmitted from the terminal A to the terminal B via the D channel, and the inter-user information set in the inter-user information memory UM of the terminal A contains the call control message (call setting message). ) Is sent to the terminal B in the form shown in FIG. The information between users sent to the terminal B here is:
This is activation information of the remote read service, and therefore does not include the arrival date / time data, calling ID data, and message content data. The message number “00” indicates that the activation is the first activation.

Upon receiving the inter-user information, in the terminal B, the CPU 2 reads the information via the S interface 1 and checks the remote read flag of the inter-user information. When the value is "1", the call is not set up by the call setting message, the call is set to the rejected state from the viewpoint of the general incoming call, and the call control message for the rejection is sent to the ISDN network. . This call control message has the same form as the call control message (release completion message) indicating release completion, and is indicated by a release completion message in FIG.

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

That is, at the terminal B, the CPU 2 confirms that the remote read flag of the inter-user information from the terminal A is “1”, and then stores the password of the inter-user information and the secret number memory SNM in the memory 5. The stored passwords are collated with each other. If the passwords do not match, the inter-user information shown in FIG. 3B is sent to the ISDN network together with the release completion message. The information between the users shown in FIG. 3 (B) has the remote read flag “1”, the data “FFFF” indicating that the password is incorrect, and the data having the message number “00” (indicating a response to the first activation). Data).

In the ISDN network, in response to the release completion message from the terminal B, a call control message (disconnection message) indicating the line disconnection is sent to the terminal A, and the inter-user information from the terminal B is included in the disconnection message and transferred. . Thereafter, two call control messages (release message and release completion message) are exchanged between the terminal A and the ISDN network, and the terminal A is released from the ISDN network and the terminal A sends the message together with the disconnection message. The CPU 2 reads the inter-user information, displays an error in the personal identification number on the message display unit 8, and ends a series of controls.

If the password transmitted from the terminal A matches the password stored in the password memory SNM of the terminal B, then the terminal B
CPU 2 identifies the message number in the inter-user information sent from the terminal A, and in this case, the message number is “00”, and thus is stored in the incoming message save memory SVM of the terminal B. The total number of messages (total number of incoming messages received and stored so far) is read from the total message memory MTM, and the total number of messages is stored in the message number area MNO of the inter-user information memory UM. At this time, the most significant bit of the message number area MNO is set to "1" to indicate that the information transmitted by the message number of the inter-user information is the total number of messages. Next, the CPU 2 refers to the message number memory NM, and in this case, “01” is stored in the message number memory NM (indicating that this is the first message read), and thus the incoming message is read. No.1 message storage area M1 of save memory SVM
Are transferred to the incoming date and time area ITM, the outgoing ID area SID and the message area MSG of the inter-user information memory UM, respectively. Further, “1” is set in the remote read flag area RF of the inter-user information memory UM to indicate that the information is inter-user according to the remote read request from the terminal A, and the personal identification number area is set.
The SNO uses no data to prevent third parties from detecting the PIN.

As described above, the inter-user information to be sent to the terminal A is set in the inter-user information memory UM of the terminal B, and this information is released in the form shown in FIG. It is sent to the ISDN network together with the completion message. The ISDN network sends the inter-user information to the terminal A together with the disconnection message to the terminal A in the same manner as described above. In the terminal A, the CPU 2 reads the inter-user information from the terminal B via the S interface 1. Next, the CPU 2 checks whether or not the most significant bit of the message number of the read inter-user information is “1”. In this case, since it is “1”, the message transmitted in the area of the message number concerned The total number is stored (saved) for remote reading of the second and subsequent messages, and then the date and time of arrival of the No. 1 message, caller ID (calling ID) and message content are displayed on the message display section 8. I do. At this time, the total number of messages may be displayed on the message display unit 8.

In the above operation, the above-mentioned inter-user information is sent from the ISDN network to the terminal A, and each call control message of a disconnection message, a release message, a release completion message is exchanged between the ISDN network and the terminal A, The terminal A is released from the ISDN network in the same manner as in the case where the passwords do not match.

Next, a description will be given of an operation in the case where the terminal A continues to read out the messages after No. 2 when the total number of messages stored in the terminal B is 2 or more.

After reading the No. 1 message, the terminal A presses the remote read key 7 again. At this time, when deleting the already read No. 1 message from the terminal B, the delete key 9 is pressed. As for the number and the password of the other party's read-out telephone device (terminal B), the number input at the time of the operation of reading the No. 1 message is stored in terminal A. Absent.

By the above operation, No. 2 is stored in the user information memory UM of the terminal A.
Information between users for remote reading activation of a message is set. That is, the remote read flag area RF is set to "1", the same password entered at the time of reading the No. 1 message is stored in the password number area SNO, and the message number area NMO indicates the No. 2 message. “02” is stored and “0” is set in the erase flag area CLF.
Or “1” (“1” when the erase key 9 is pressed, “0” when it is not pressed), the incoming date and time area ITM,
The D area SID and the message area MSG have no data.

The information between the users set as described above is transmitted from the terminal A via the D channel of the ISDN network together with the call setting message through the S interface 1 under the control of the CPU 2 under the control of the CPU 2 in the same manner as at the time of starting at the time of reading the No. 1 message. B is sent. The form of the inter-user information at this time is as shown in FIG. 3 (D).

In the terminal B, when the CPU 2 reads the inter-user information via the S interface 1, the CPU 2 checks the remote read flag, the password and the message number of the inter-user information. Is "1" (in the case of "0", the general incoming call process is performed). The password is correct (if incorrect, the operation shifts to the operation of mismatching the password in FIG. 2). Since the message number is not “00”, the CPU 2 checks the erasure flag of the inter-user information.

When the erasure flag of the inter-user information sent from the terminal A is "0", the CPU 2 of the terminal B reads this and sends the No. 1 message sent to the terminal A in the above operation as it is to the No. 1 of the incoming message save memory SVM. .1 held in the message storage area M1, and received message date and time stored in the No. 2 message storage area M2 of the received message save memory SVM by identifying that the message number of the inter-user information is `` 02 '', The data indicating the calling ID and the message content is stored in the receiving date and time area ITM of the user-to-user information memory UM.
Transfer to the calling ID area SID and the message area MSG respectively, and set the remote read flag area RF to [1], the password number area SNO to no data, the message number area MNO to [02], and the erasure flag area CLF to [0]. I do.

The inter-user information set in the inter-user information memory UM as described above is sent from the terminal B to the ISDN network together with the release completion message in the form shown in FIG. The message is transferred to the terminal A together with the message.

In terminal A, the information between the users is transmitted to S interface 1
The CPU 2 reads the received date and time of the No. 2 message, the calling ID, and the message content on the message display section 8 because the erasure flag is "0".

When the erasure flag of the inter-user information sent from the terminal A is “1”, in the terminal B, the CPU 2 reads “1” of the erasure flag and corresponds to the number before the message number of the inter-user information. Message, in this case, the No. 1 message is received.
Is deleted from the No. 1 message storage area M1, and the messages stored after the No. 2 message storage area M2 are moved to the previous message storage areas, respectively. This
No. 2 message is newly designated as No. 1 message.
The No. 1 message is transferred from the incoming message save memory SVM to the inter-user information memory UM, and the inter-user information sent from the terminal B to the terminal A is configured in the same manner as the operation when the deletion flag is “0”. You.

As shown in FIG. 3 (F), the inter-user information at this time is such that the remote read flag is “1”, the password is no data, the message number is “01” (as a result of deleting the No. 1 message, The No. 2 message to be sent is newly sent as No. 1 message, so that the deletion of the previously sent message can be confirmed at the terminal A.), the deletion flag is “1”, the date and time of the incoming call, the calling ID and the message The content is composed of the new No. 1 message (old No. 2 message).

This user-to-user information is transmitted from terminal B to ISDN
It is sent to the network together with the release complete message, and the ISDN network forwards it to the terminal A together with the disconnection message.

In the terminal A, when the CPU 2 reads the inter-user information via the S interface 1, the CPU 2 confirms that the message number of the inter-user information is the new message number (in this case, the terminal A When sending
“2” is “01” at the time of reception at the terminal A. ) And the deletion flag is “1”,
A value obtained by subtracting 1 from each of the message number and the total number of messages is saved, and the date and time of arrival of the new No. 1 message, the calling ID, and the message content are displayed on the message display section 8. With this display, the terminal A can read the second message received and stored in the terminal B.
At this time, if the total number of messages is displayed on the display unit 8, the terminal A can also know the remaining number of incoming messages to the terminal B.

The reading of the message after No. 3 stored in the terminal B by the terminal A can be performed by repeating the operation described above.

In addition, when the incoming message recorded in the terminal B disappears and the total number of messages saved in the terminal A becomes “0”, and then the remote reading operation of the incoming message is performed from the terminal A, Since the total number of messages is "0", the CPU 2 of the terminal A ends the call without setting up a call to the ISDN network.

After the terminal A reads out the message arriving at the terminal B as described above and performs an end operation at the terminal A, the CPU 2 performs an end process to end a series of remote read control.

In the above embodiment, the remote readout activation information transmitted from the readout terminal A to the readout terminal B is together with a call control message for call setup, and the incoming message information transmitted from the terminal B to the terminal A is This is an example in which the call control messages for release completion and disconnection are respectively sent to the other party, but the call control messages exchanged between the terminal A and the terminal B include, in addition to the above, for example, Since there are a number of call control messages such as a call control message for calling the calling side terminal and the transmission of information between users is possible in any of the transmission phases of the call control message, the remote readout is performed. The activation information and the incoming message information are transmitted to the other party in the transmission phase of any call control message unless the transmission direction is different. It is possible to send.

〔The invention's effect〕

As described above, the present invention is directed to a user who can transmit via a D channel of an ISDN network together with a call control message transmitted between telephone devices, for example, when setting up a call, when disconnecting and releasing a call, and the like. The remote reading command of the incoming message and the incoming message are transmitted using the inter-information, without setting up the call,
At the preceding stage (at the time of call setup control) or at the later stage (at the time of call disconnection / release control), all necessary information is exchanged.
The transfer of the incoming message takes place in a very short time, so that the communication costs are very low.

The operation for remote reading can be performed by dialing the number of the other party's telephone device and the password, and then operating the remote reading button. Further, reading the second and subsequent messages can be performed only by operating the above buttons. In addition, transmitted messages are displayed visually, so that there is little need to repeat access to the other party's telephone device.

As described above, the present invention has various advantages, and its effects are extremely large.
