Abstract

PURPOSE:To inform independently and quickly notice information from a networ, by transferring the notice information sent from the communication network to a terminal generated during the storage of message, transfer, conversion or after processing via a signal line instead of a communication line, while keeping code information. CONSTITUTION:When an outgoing facsimile terminal T1 performs hook-off to indicate the call at the start of communication, the hook-off state is informed to a subscriber exchange X1 via a signal path 1b and the X1 returns a response 1 to the terminal T1. Further, the terminal T1 dials the facsimile communication service request special number via a communication processing node CPN and the number of an incoming terminal T2, the dial information is transferred to the X1 via the path 1b, the X1 transmits the connection request to the node CPN via a common line 2b, and when the response 2 is received, the X1 connects the line 1a and a signal line 2a between stations, returns a response 3 to the T1 to inform the end of call setting. The X1 starts the transmission of the communication text of the 2nd page.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a line information notification system, and particularly to a system for transmitting notification information from a communication network to a terminal.

In the conventional facsimile communication network, facsimile
When an IJ message is not delivered to the recipient, a non-delivery notification is created in the communication network as a facsimile to notify the sender of the non-delivery. The notification was sent back to the sender's receiver. In another conventional example, when reading a mark sheet sent from a facsimile transmitter within a communication network, if the mark sheet cannot be read due to an abnormality such as tilt, a mark sheet reception rejection notification is sent to that effect. As in the case of the non-delivery notification above, the sender's receiver was sent back and notified.

This kind of conventional notification means has the disadvantage that extra processing is required to create the above-mentioned non-delivery notification text, mark sheet acceptance refusal notification text, etc. within the communication network. In addition, in order to send the notification back to the caller, it is necessary that the caller is not busy on a subscriber line such as a conventional analog telephone network; conversely, the subscriber line is used to send the notification back. This had the disadvantage that the subscriber line could not be used for other communications.

The present invention provides a digital subscriber line in which a subscriber line is composed of a communication path for transferring messages from a caller to a called party, and a signal path for transferring number information, etc. for controlling a communication network. This is to prevent the above-mentioned drawbacks from occurring in a communication network using public lines.

In other words, according to the present invention, the notification information from the communication network to the terminal generated during or after the storage, transfer, and conversion of messages in the communication network is transferred as code information via the signal path instead of the communication path. It is something.

Note that the signal path and the communication path do not need to be physically separate lines, and it is sufficient if one transmission path is logically separate lines using time division multiplexing or band division multiplexing technology.

FIG. 1 shows an example of the configuration of a communication network for explaining the present invention. T1 is a transmitting terminal, such as a facsimile E/IJ terminal, 1.
4 is a subscriber line, la and 4a are communication paths for transferring messages between calling and receiving parties, lb and 4b are signal paths for transferring dialed numbers, etc.;

X2 is a subscriber exchange, C8E1 to C8E3 are common line signaling devices, 2a and 3a are interoffice communication paths, 2b and 3
b is a common line, CPN is a communication processing mate having a message storage function, and N is a communication network. The case where the message is a facsimile message will be explained below.

FIG. 2 shows an example of a signal sequence for explaining the operation of the communication network of FIG. 1. The solid line arrows in FIG. 2 are information on the communication path, and the broken line arrows are signals on the signal path or common line.

When the originating facsimile IJ terminal T1 performs a hook-off to indicate the origination of a call at the start of a call, the hook-off state is notified to the subscriber exchange X via the signal path 1b, and the subscriber exchange X sends a response 1 to the terminal T1. return. Thereafter, the terminal T1 dials the facsimile communication service request special number via the communication processing node CPN and the number of the destination terminal T2, and the dial information is transferred to the subscriber exchange X1 via the signal path 1b, and the subscriber exchange X1 further A connection request is sent to the communication processing node CPN via the common line 2b, and when response 2 is received, signal path 1a and interoffice signal path 2a are connected, response 3 is returned to the originating facsimile IJ terminal T1, and the call setup is completed. Notify when completed. The originating facsimile terminal T1 starts transmitting the second page of the message. On the other hand, the communication processing node CPN is
After one page has been stored, an incoming call request is sent to the terminating local exchange X2 via the common line 3b in order to transmit the message to the terminating terminal T2. The subscriber exchange X2 tries to call the destination terminal T2, but if it turns out that it is impossible to call the destination terminal T2 due to, for example, a disconnection of the subscriber line 4, it returns a negative response to the communication processing node CPN via the common line 3b. .

Upon receiving the negative response, the communication processing node CPN determines that the first page of the previously accumulated message and subsequent pages are undeliverable;
The transmission to the destination terminal T2 is abandoned, the non-delivery notification is returned to the subscriber exchange X1 via the common line 2b, and the subscriber exchange X further sends the non-delivery notification via the signal path ib to the originating facsimile terminal T.
Return to 1. When the originating facsimile IJ terminal T1 receives the non-delivery notification, it abandons sending the message on the second page that is being sent, hooks on, and notifies the subscriber exchange X that the call is to be disconnected. The subscriber exchange X1 notifies the communication processing node CPN via the common line 2b, and upon receiving the response 5, disconnects the signal path 1a and the interoffice signal path 2a.

The above operation example is an example of a non-delivery notification text. However, when the first page is a mark sheet and the communication processing node CPN returns a mark sheet acceptance rejection notice while reading the mark sheet, or when notifying communication charges, For example, the present invention is applicable to various notifications from the network.

10 is a main control section, 11 is a main memory, 12 is an image information receiving section, 13 is an image information memory, and 14 is an image information transmitting section.

The signal on the signal path 1b from the terminal T1 is distributed by the multiplexer 8, received and analyzed by the signal transmitter/receiver 7 via the signal path 1b', and notifies the main controller 5 of necessary control information. 5
stores the status of the subscriber line 1 and the like in the main memory 6 as necessary. If it is necessary to transfer the signal to the communication processing node CPN, for example, CCITT.

The main controller 5 creates a signal in accordance with the common line signaling system of /I67 and sends it to the common line 2b via the common line signaling device C3EI. Communication processing node CPN is common line signaling device C8
The signal is received by E 3 and notified to the main control unit 10 .

Information on the communication path 1a from the terminal T1, that is, the message, is distributed by the multiplexing section 8 and sent to the digital exchange section 9 via the communication path 1a'. In the main control unit 5, the communication paths 1a' to 2a
If the two stations are connected by digital exchange, the message is received by the image information receiving section 12 via the inter-office communication path 2a. . The image information receiving section 12 sequentially stores the messages in the image information memory 13, and upon completion of the evaluation, sends a response via the inter-office communication path 2a, the digital exchange section 9, and the communication paths 1a' and 1a. It is sent back to terminal T1.

The main control unit 10 may include a common line signal device C3E3,
An incoming call request signal, etc. is transferred to the destination local exchange X2 via the common line 3b. When transmitting image information, the main control section 10 controls the image information transmitting section 14, and the image information transmitting section 14 sequentially reads the correspondence from the image information memory 13, and
a to the destination terminal T2 via the destination local exchange X2.

The main control unit 10 sends a negative response to the incoming call request to the destination local exchange X2 through the inter-office communication path 3b and the common line signaling device C3E
3, the message already stored in the image information memory 13 is determined to be undelivered. In addition, as a method for determining non-delivery, for example, first
There is also a method of attempting to re-call, that is, sending a call request, five times within a maximum of 30 minutes after issuing a call termination request, and determining that the call has not been delivered only when all attempts fail. In the above example, in order to simplify the explanation, the call is determined to be undeliverable without calling again.

If the main control unit 10 determines that the message has not been delivered, it discards the first page that has already been received and the second page that is currently being received, and causes the image information receiving unit to stop the operation that is currently receiving the second page. Furthermore, a non-delivery notification signal is created using only the code information, and the common line signal device C3
It is transmitted from E3 to subscriber exchange X1 via common line 2b. Local exchange X1 transmits the signal to common signal line equipment C3E.
The main control unit 5 receives the non-delivery notification signal through the signal line l.
The signal is converted into a signal format compatible with the subscriber line signaling system on line b, and sent to the signal path lb' via the signal transmitting/receiving section 7 as code information. The non-delivery notification signal is multiplexed by the multiplexer 8 and transmitted via the subscriber line 1 to the originating facsimile terminal T1. During this time, without interfering with the information transfer on the communication path 1a',
Signal transmission takes place independently.

When a call is made from the terminal 1, a hook-off operation is performed using the dial operation section 20, and a signal indicating the state is multiplexed at the multiplexing section 15 via the signal path lb' and sent to the subscriber line 1). put out. When the signal transmitting/receiving section 16 receives response 1 from the communication network N via the signal path 1b', the signal transmitting/receiving section 16 lights up a dial ready lamp, for example, and the caller performs a dial operation using the dial operation section 20, and the signal transmitting/receiving section 16 receives the response 1 from the communication network N via the signal path 1b'. The unit 16 transmits the dial to the communication network N via the subscriber line 1 via the multiplexing unit 15 in the signal format of the subscriber line signaling system on the signal path 1b''. When the signal is received by the signal transmitting/receiving section 16 via the 7-axis I
It is read by the J transmitting/receiving section 18 and transmitted from the communication path 18'' via the multiplexing section 15 to the communication network N via the subscriber line 1 according to a prescribed protocol.Facsimile transmitting/receiving section 1
8 starts transmitting the next second page upon receiving the response 4 shown in FIG. 2 via the communication path 1a.

Regardless of whether or not the communication path 1a is in use, the terminal T1 can send and receive signals to and from the communication network N via the signal transmission and reception unit 16 via the signal path 1b. When the notification signal is received by the signal transmitting/receiving section 16 via the signal path 1b'', the notification information is printed out by the printer section 19,
The sender is informed that there has been a notification from the communication network N that the first and subsequent pages that were previously sent to the communication network N have not been delivered.

Based on the printed information, the sender takes measures such as stopping the transmission of the message that is currently being sent.

As explained above, according to the present invention, when transferring notification information from a network to a terminal, there is no need to create a notification text in image information format or to make a notification by voice, and the communication path of the terminal Code information can be sent to terminals independently in a short time without interfering with communication using the code.

Especially when the terminal is a facsimile, even if the terminal is in communication for a long time, it is possible to promptly notify notification information from the network independently of the communication.
