Abstract

PROBLEM TO BE SOLVED: To simultaneously transmit a transmitted original generated thereafter in addition to an original at the time of a non-terminated call by performing transmission including the pertinent document when polling reception is performed from the opposite party of a caller number matched with a transmission destination number stored in a document management means. SOLUTION: In the case of detecting a call, when a facsimile procedure can not be performed in a communication means 2, a terminated call is cut off and restored in a call control means 1 and the caller number informed at the time of the call termination is stored in a call management means 4. At the time when the facsimile procedure can be performed in the communication means 2, a communication management means 5 newly originates a call so as to perform the polling reception to the caller number stored in the calling management means 4. When call origination becomes the non-terminated call, a transmission document and the transmission destination number are stored in the document management means 6. When the polling reception is performed from the opposite party of the caller number matching the transmission destination number stored in the document management means 6, the transmission including at least the pertinent transmission document is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine for transmitting a document by communication via a line of a comprehensive service digital network.

[0002]

2. Description of the Related Art Conventionally, in a facsimile machine connected to a line of an integrated services digital network (ISDN) to send and receive texts, when a call is missed because all communication channels of the line are in use. Facsimile machines equipped with coping means have been proposed (for example, Japanese Patent Application Laid-Open Nos. 5-95467 and 3-102947).

For example, a facsimile apparatus disclosed in Japanese Unexamined Patent Publication No. 5-95467 discloses a communication channel detecting means for detecting a use state of a communication channel of an ISDN line and an ISDN.
From the calling side terminal, a non-received caller number storage means for storing the caller number notified from the ISDN line when a new facsimile call is received due to a call being missed because the communication channel of the line is in use. Using the communication number storage means for storing the communication number to be sent, and the instruction information for performing automatic polling reception from the called side terminal to the calling side terminal corresponding to the caller number of the missed call, using the control channel. If any communication channel is released after the occurrence of the missed call and the instruction information notification means to notify, the caller number stored in the missed caller number storage means is called and communication is automatically performed. This is a configuration including polling reception executing means for executing polling reception for notifying a number using a control channel.

Further, in this conventional facsimile apparatus,
A communication number notification means for notifying the caller terminal of the communication number to the callee terminal using the control channel at the time of call origination, and automatic polling reception from the callee terminal when the call is rejected. Instruction information receiving means for receiving instruction information using the control channel, and an original document that stores the original document together with the communication number if the original document to be transmitted by the calling terminal when the incoming call is rejected is not stored in the memory A configuration including a storage unit and a document transmission unit that receives a communication number from a terminal that has been refused an incoming call using a control channel and transmits the document stored in a memory corresponding to the communication number by automatic polling Is.

According to this conventional facsimile apparatus, the original transmitting means transmits the original to be transmitted by the calling terminal when the incoming call is rejected, which was waiting at the same time when the communication of the called terminal was completed. Therefore, it is possible to efficiently transmit a manuscript or the like having a high degree of urgency.

In the communication system described in Japanese Patent Laid-Open No. 102947/1993, when a calling terminal device, which is a facsimile machine, polls a called terminal device via ISDN, a call is set in the calling terminal device. Sometimes a means is provided to set the calling number and polling request in the message,
The incoming call terminal device is provided with means for recognizing the calling party number and the polling request from the message at the time of incoming call. When the incoming call terminal device is busy and the document to be transmitted in response to the polling request is set, the incoming call terminal device is called. The terminal device uses the signal channel to notify the calling terminal device of the busy state, and at the same time rejects the incoming call by sending a message that the document for which polling has been requested is sent after releasing the busy state,
After the busy state is released, the calling terminal device is called and the document requested for polling is transmitted through the information channel.

In this conventional facsimile machine, the facsimile machine serving as the calling side terminal device is called by the calling side facsimile machine immediately after the busy state of the facsimile machine serving as the called side terminal device is released. Since the original document of the facsimile machine on the call side can be transmitted, it is not necessary to wait for the redial time and communication efficiency can be improved.

[0008]

However, in the above-mentioned conventional facsimile apparatus, when an original call is sent when a call is missed, the called terminal of the missed call is newly notified of the caller number. However, in this case, there is a problem that the calling terminal of the missed call can only send the document when the missed call was made.

This is because in the conventional apparatus, a document which is a non-received call and is not transmitted is automatically polled from the called terminal, but the communication number sent by the calling terminal at the time of occurrence of the missed call is rejected. This is because the notified terminal sends a notification and the original stored in the corresponding memory is transmitted based on the communication number.

Further, in the conventional facsimile apparatus, the communication number associated with the document stored in the memory by the automatic polling reception and the instruction information for performing the automatic polling reception are exchanged using the control channel of the ISDN line. Therefore, the communication between the calling side terminal and the called side terminal is not serviced by the calling side depending on the connection between networks or depending on the type of ISDN line to be connected. It may not be transmitted from the terminal to the called terminal. Therefore, there is a problem in that the communication number, which is conventionally required for transmitting the document stored in the memory by the automatic polling reception, cannot be given and received, and the automatic polling may not be performed.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a facsimile apparatus that can simultaneously transmit a transmission document generated after a missed call.

Another object of the present invention is to eliminate the need for the instruction information for automatic polling reception to eliminate the need for information transmission on the control channel and to ensure the reliability of communication without depending on the applied line and destination. An object of the present invention is to provide a facsimile device that can improve the property.

[0013]

In order to achieve the above object, in the invention according to claim 1, call control means for controlling outgoing and incoming calls, communication means for performing a facsimile procedure, and call control by the call control means. A network control means for separately controlling signals on a communication line in which a signal and a facsimile procedure signal by the communication means are superposed, and a caller for storing a caller number notified with an incoming signal for automatic polling reception. The management means and the call control means through the network control means determine whether or not the incoming signal has been disconnected and recovered without responding with a facsimile procedure signal to the incoming signal detected. The caller number is stored in the means, and after the facsimile procedure by the communication means becomes possible, the caller number stored in the call management means is reissued. It is obtained by a configuration having a signal managing means.

In order to achieve the above-mentioned object, the invention according to claim 2 further comprises a document management means for storing the transmission destination number together with the transmission document when the call connection with the transmission destination cannot be established at the time of transmission, and communication is performed. The management means determines whether or not the destination number equal to the caller number notified with the incoming signal upon receipt is stored in the document management means, and if it is determined to be stored, at least read from the document management means. The transmission document corresponding to the destination number is polled and transmitted via the call control means and the network control means.

According to another aspect of the present invention, when the call control means detects an incoming call and the communication means cannot perform the facsimile procedure, the call control means disconnects and restores the incoming call, and the caller is notified when the incoming call arrives. The number is stored in the call management means, and the communication management means makes a new call for polling reception for the caller number stored by the call management means when the facsimile procedure can be performed by the communication means. When the facsimile device, which is the called-side terminal of the missed call, receives the polling for the notified caller number, it receives the communication number corresponding to the transmission of the document that becomes the missed call and the automatic polling reception. It is possible to eliminate the need to transmit the indicating information shown.

Further, in the facsimile apparatus according to the second aspect of the present invention, the call control means transmits the transmission document in order to transmit the transmission document, and when the transmission is a missed call, the document management means stores the transmission document and the destination number. If an incoming call is detected by the call control means, if the communication management means performs polling reception from the other party of the sender number that matches the destination number stored by the document management means, at least the corresponding transmission document is included. Since the transmission is performed as described above, it is possible to transmit the transmission document generated after the missed call together with the corresponding transmission document.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of a facsimile apparatus according to the present invention. As shown in the figure, this facsimile apparatus transmits a call control means 1 for controlling outgoing and incoming calls, a communication means 2 for performing a facsimile procedure, a call control signal by the call control means 1 and a facsimile procedure signal by the communication means 2. It is composed of a network control unit 3 for separately and independently controlling signals of the integrated service digital network which is the communication line 7 superposed on each other, a call management unit 4, a communication management unit 5, and a document management unit 6. It

The call management means 4 stores the caller number to be notified along with the incoming signal when the incoming signal is not disconnected by the facsimile procedure signal and the incoming signal is restored by disconnection. . The communication management means 5 again has a function of transmitting a caller number stored by the call management means 4 for polling transmission and a function of performing a polling transmission when there is a transmission document having a destination number equal to the caller number when receiving a call. With. The document management unit 6 manages the delivery of the transmitted document along with the destination number when the call connection cannot be established at the time of calling.

Next, the operation of the embodiment of FIG. 1 will be described with reference to the flowcharts of FIGS. 2 and 3.
First, the operation when receiving a call will be described with reference to the flowchart of FIG. The communication management means 5 determines whether there is an incoming call based on a signal input through the network control means 3 and the call control means 1 (step 10). When there is an incoming call, the communication management means 5 determines whether communication is possible. (Step 1
1). If communication is already in progress and the communication means 2 is operating, or if there is no free information channel in the ISDN network, communication is not possible, so after receiving the incoming call and performing disconnection recovery (step 12), communication is performed. When it becomes possible, a call reservation is made in order to make a call from the called side and receive automatic polling (step 13).

When it is judged in step 11 that communication is possible, the communication management means 5 sends the caller number notified by the call setting, which is a call control signal in ISDN, and the document stored in the document management means 6. It is determined whether the destination number matches (step 14). If it is determined in step 14 that they match, the presence of the polling document is notified in the facsimile procedure controlled by the communication means 2 (step 1
5) Further, it is judged whether the facsimile procedure is the polling procedure (step 16). If it is the polling procedure, the matched original document is polled and transmitted (step 1).
7).

On the other hand, if it is determined in step 14 that the document management means 6 does not have the transmission destination number of the original document that matches the caller number notified by the call setting, after notifying that there is no polling transmission document in the facsimile procedure. (Step 18), shift to normal reception (step 19).
Also, when it is determined in step 16 that the polling procedure is not performed, normal reception is performed (step 19).

Next, the transmission operation of the embodiment of FIG. 1 will be described with reference to the flowchart of FIG. The communication management means 5 determines whether or not there is a call request (step 2
0), if there is a call origination request, it is subsequently determined whether communication is possible (step 21). If communication is already in progress and the communication means 2 is operating, or if there is no free information channel in the ISDN network, communication is not possible, and a call reservation is made to make another call (step 30).

When it is determined in step 21 that communication is possible, dialing is performed by the call setting which is a call control signal in ISDN (step 22). Further, the communication management means 5 determines whether the dial due to the call setting is not accepted and the disconnection is recovered (step 23). If it is determined that the disconnection has been restored, a call reservation for making a call again is made (step 24). At this time, the destination number is stored together with the original document to be transmitted by the document management means 6.

On the other hand, if it is determined in step 23 that the disconnection is not recovered, the communication management means 5 determines whether the call is being made for polling reception (step 2).
5) If the polling reception by the transmission reservation in step 13 of FIG. 2 is being performed, it is determined whether or not the other party has a polling reception document, and if so, the polling reception procedure is performed (step 27), and if not The disconnection is restored (step 28). If it is not determined in step 25 that the call is not being sent for polling reception, the communication means 2 is caused to perform the sending operation (step 29).

The above-described incoming call operation and outgoing call operation are alternately processed.

Next, the communication procedure of the system having the facsimile apparatus of the above-described embodiment on the calling side and the called side will be described with reference to the sequence diagram of FIG. In FIG. 4, the signal within the dotted line is a facsimile procedure signal, and the other signals are call control signals. First, the call control means 1 of the calling side device (facsimile device) A performs call setting connection. When the calling device A originates a call setting message (step 41), the network indicates to the calling device A that the call is accepted (step 42). Facsimile machine)
B is notified of the incoming call by a call setup message (step 4).
3).

At this time, if the called device B is in the communication disabled state, the incoming call is rejected with a release completion message (step 44). When the network receives this release completion message, it indicates recovery to the called side device A with a disconnection message (step 45), and responds with a release message from the called side device A to the recovery (step 46). Then, the restoration is completed (step 47).

After that, when the called device B is in a communicable state, the call setup message is used (step 48), and the call setup acceptance message indicates that the call is accepted (step 49). Further, in synchronization with this, the incoming call is notified to the calling side device A by the call setting message, and the calling number is notified to the calling side device A by the caller number notification information element of the call setting message (step 50). ).

As a result, when the calling side device A indicates that the incoming call is possible by the response message (step 51), the network instructs the calling side device A to receive the incoming call by the response confirmation message (step 52), and in synchronization with this. A response message is sent to the called device B to indicate the completion of the call (step 53).

Then, a facsimile procedure is executed between the called device B and the calling device A. That is, the calling device A determines whether there is a document to be transmitted according to the caller number of the call setting message, and if there is a document, the DIS which is the capability notification indicates that there is a polling transmission document (step 5).
4).

Since the called device B receives the original document instead of the communication which is a non-received call, it sends DTC indicating transmission / reception reversal to the calling device A (step 55). Then, the calling side device A sends the facsimile document to the called side device B by the transmission command DCS (steps 56 and 57), and when the sending ends, notifies the called side device B of the end of transmission by EOP (step). 58). When the document is correctly delivered, the called device B responds to the calling device A with MCF (step 5).
9) Then, the calling device A disconnects at the DCN (step 60).

As described above, according to the present invention, when an unanswered call is made when a document is transmitted, a document which has become an unanswered call and is not sent is automatically polled and received from the called terminal, but is polled and received. Since the calling terminal A determines whether or not there is a document to be sent based on the sender number, the calling terminal A for a missed call is a document other than the document that has become the missed call. Even if there is a document to the same destination (callee terminal B), it can be transmitted at the same time as the document for which the call has been missed.

Further, since the facsimile procedure element is only the caller number notified in the call setup, there is no need for additional information transmission on the control channel in ISDN. Therefore, in this embodiment, the applicable line and Automatic polling reception can be performed without depending on the destination, and communication reliability can be increased.

In FIG. 4, when the facsimile procedure is completed, the process returns to the call control procedure, and the called side device B sends a disconnection message (step 61), whereby the calling side device A is notified of the disconnection message. Therefore, when the calling device A responds to the recovery with a release message (step 63) (step 63), the release message is notified to the called device B (step 64). In response to this, the called device B sends a release completion message (step 6).
5) The restoration is completed by notifying the calling side device A of this (step 66).

Incidentally, steps 61, 64 and 65 correspond to the disconnection recovery of step 28 of FIG.
3, 66 correspond to the disconnection recovery of step 12 of FIG.
Although the facsimile procedure is shown as the G3 facsimile procedure, the procedure may be the G4 facsimile procedure.

[0036]

As described above, according to the present invention,
Indicates that the facsimile machine, which is the called terminal of the missed call, receives the polling number for the notified caller number and the communication number corresponding to the transmission of the document that is the missed call and the automatic polling. Since the transmission of instruction information can be made unnecessary, automatic polling reception can be performed immediately after the facsimile procedure of the called terminal becomes possible without depending on the applied line and destination, and communication reliability is improved. be able to.

Further, according to the present invention, when a document which is a non-received call and is not transmitted is automatically polled from the callee side terminal, if the call control means detects the incoming call on the polled reception side, the document is received. When polling is received from the other party with the sender number that matches the destination number stored by the management means, at least the corresponding transmission document is included in the transmission. Even if it is a document to the same destination, it can be transmitted at the same time as the corresponding transmission document stored in the document management means.
