Abstract

PROBLEM TO BE SOLVED: To prevent an erroneous transmission and to improve reliability of an equipment by comparing a telephone number stored in a caller's telephone number storage part with the telephone number stored in a callee's number storage part to perform polling communication by a caller's side (a transmitting side) and transmitting a document for polling transmission only when both telephone numbers coincide. SOLUTION: The telephone number stored in the caller's telephone number storage part 4 and the telephone number stored in the callee's number storage part 11 to perform polling communication by the callee's side (the transmitting side) are compared and only when both telephone numbers coincide, a transmission ability bit in a frame of a digital identification signal DIS is set as '1'. Information indicating the transmission ability is very important for start of the polling communication and if the information is set as '0', the polling communication is not started even if the polling communication is wished by the caller's side. Consequently, the erroneous transmission is prevented and also the reliability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for performing polling transmission, and more particularly, to a line which receives a calling number service, and which receives an ITU-T V.10 signal. 8 standards and V.8. The present invention relates to a facsimile apparatus for performing standard 34 communication or a communication apparatus having a built-in facsimile function.

[0002]

2. Description of the Related Art For facsimile machines, CCIT
Various standards are defined by the T Recommendation, and the V-Series modem recommendations include 8 standards (V.8 mode),
V. 21 standard (V.21H mode), V.21 standard. Communication control procedures at the time of communication are defined for modems conforming to the V.34 standard (V.34 mode) [for example, ITU-T, V series (modem-related etc.) Recommendations, 1994, New Japan ITU Association Issue〕. If a facsimile machine equipped with a modem according to the communication control procedure specified in this CCITT recommendation (especially recommendation T.30) is used,
Communication is possible even between modems having different standards.

[0003] When performing polling communication, first, the called side notifies the calling side by a protocol signal that a polling transmission original (or a memory file storing the polling transmission original) is ready. And then
By transmitting a polling request from the calling side that has received this notification, transmission of the transmission original is started. After the start of the polling communication, in the standard protocol, the calling side can be confirmed by communication of the protocol signal SEP. However, when a plurality of polling transmission originals are stored in a memory file and the destination of each transmission original is different, there is a limit even if the ID included in the protocol signal SEP is changed. However, there is a possibility that an erroneous transmission is performed to a destination whose ID coincides with that of the user. For this reason, there has been a problem that confidentiality cannot be completely maintained, and the reliability of polling communication decreases.

In order to solve such a problem, in recent years,
An exchange having a function of notifying the called party of the telephone number of the calling party has been developed, and the start of the subscriber service is scheduled. As a technique using such a function, an incoming call control system that uses a calling ID (telephone number data) and displays the presence / absence of a call and a calling ID on a receiving terminal when busy is known (for example, a special call control method). JP-A-6-152753). This incoming call control system is a function implemented in cooperation with both the exchange and the terminal, but no consideration is given to improving the reliability of polling communication. Similarly, a caller ID notifying device that outputs a second call signal according to a calling ID is also known (for example, Japanese Patent Application Laid-Open No. 4-349755). This caller ID notification device is also one of the applications using the calling ID, but does not take into consideration the improvement of the reliability of the polling communication. Here, the polling communication will be described.

FIG. 9 shows a typical polling communication.
It is a figure which shows the outline | summary of the sequence. In the figure, the upper column is the calling side (receiving side), the lower column is the called side (transmitting side),
ED, CSI, DIS, CIG, DTC, TSI, DC
S, TCF, CFR, PIX, PPS-EOP, MC
F and DCN indicate signals.

In the sequence of FIG. 9, since no polling ID is communicated, anyone can receive a polling document set on the called side, although it is simple. Therefore, there is no security and confidentiality cannot be maintained. To address such issues, ID
It specifies polled communication with tag.

FIG. 10 is a diagram showing an outline of the sequence of polling communication with ID. Reference numerals in the figure are the same as those in FIG. 9, and SEP indicates a frame of the protocol signal.

[0010] A frame of a protocol signal SEP is added to the sequence shown in FIG. And
By using the ID in the frame of the protocol signal SEP, it is possible (permitted) to perform polling transmission only to a specific destination. If the IDs do not match in this case, the line is immediately disconnected.

FIG. 11 is a diagram showing an outline of a sequence when the IDs are different in the polling communication with ID shown in FIG. Reference numerals in the figure are the same as those in FIG.

The ID in the frame of the protocol signal SEP
As a result of the comparison, if they do not match, as shown in FIG. 11, the line is disconnected from the called side and the communication is terminated. Therefore, the security is higher than that of the normal polling communication shown in FIG. However, even if this method is adopted, the ID can be set arbitrarily, so that a case where the IDs coincide with each other is assumed. Also, in order to avoid unnecessary polling communication and reduce communication costs,
A method using a frame of the digital identification signal DIS is also known.

FIG. 12 is a diagram showing bit allocation of the digital identification signal DIS.

FIG. 12 shows a digital identification signal DIS.
The information indicating that transmission is possible is assigned to the ninth bit (bit No. 9), and the information indicating that reception is possible is assigned to the next tenth bit. Then, when there is a document that can be transmitted on the receiving side, the corresponding bit is set to “1”. That is, when the polling transmission original is set on the called side,
Alternatively, when there is a memory file for polling transmission, the ninth transmittable bit shown in FIG. 12 is set.

FIG. 13 is a diagram showing an outline of a sequence for disconnecting the line from the calling side when the transmittable bit in the frame of the digital identification signal DIS is not set. The reference numerals in the figure are the same as those in FIG.

As shown in FIG. 13, in the polling communication, the calling side checks the transmittable bit in the frame of the digital identification signal DIS, and immediately detects that the bit is not set, and immediately disconnects the disconnection command signal. Generate a DCN and disconnect the line.

FIG. 14 is a diagram showing an outline of the sequence of the outgoing telephone number notification from the exchange. Reference numerals in the figure are the same as those in FIG.

In the sequence shown in FIG. 14, a communication sequence portion of the telephone number of the calling side sent from the exchange is added. When the calling party places a call, the called party first undergoes a polarity reversal. Thereafter, when an ID receiving terminal activation signal arrives and the called terminal responds by connecting the line, the calling ID (telephone number data) becomes V. It is transmitted according to the 23 standard. When reception is completed at the called terminal, the line is released. Then, when the original calling signal (ringing signal) is sent and the called terminal responds by closing the line, communication is started.

[0017]

As described in connection with the prior art, a number of measures have been proposed for polling communication in order to prevent erroneous transmission of a transmitted document and improve reliability. Further, devices and systems for notifying the called party of the telephone number of the caller have been developed. However, a reliable method or device for maintaining confidentiality (enhancing security) in polling communication has not been proposed yet. An object of the present invention is to maintain confidentiality in polling communication and improve communication reliability.

The above is the outline of the configuration and operation of the facsimile apparatus common to each embodiment of the present invention.

First Embodiment This first embodiment corresponds to the first aspect of the present invention, but also relates to the second to fourth aspects of the present invention.
The invention of claim 1 is a basic invention. In the first embodiment, in order to maintain confidentiality in polling communication (to increase security), a protocol signal SE is used.
It is characterized in that the transmission of the polling transmission original is started after confirming not only the ID in the frame of P but also the telephone number of the calling side.

As shown in FIG. 14, the telephone number of the calling side is transmitted from the exchange, and this telephone number (calling ID) is transmitted.
A communication method that determines a response or a non-response on the receiving side by using a communication has already been proposed. In the case of this communication method, the line is temporarily opened after receiving the telephone number of the calling side sent from the exchange. In the first embodiment, the received telephone number of the calling side is stored, and when the line is closed by the next call signal, the telephone number of the calling side stored earlier is stored. Is determined to match with the destination telephone number in the polling transmission file created by the called party. As a result of the comparison, the calling phone number and
If the destination telephone number set in the polling transmission document matches, the digital identification signal DI shown in FIG.
The information indicating transmittable assigned to the 9th bit of S (bit No. 9) is set to “1”. The information indicating that transmission is possible is extremely important for the start of polling communication. When this information is set to "0", polling communication is started even if the calling side desires polling communication. It is not possible. Normally, the information indicating that the ninth bit of the digital identification signal DIS can be transmitted is set to “0” when there is no telephone number of the calling side and no polling transmission original corresponding to the telephone number on the receiving side. Set. However, according to the first embodiment, the telephone number of the calling party holding the information indicating that transmission is possible matches the destination telephone number of the polling transmission file created by the called party. Since it is set to "1" after confirming the above, erroneous transmission is prevented and the reliability is remarkably improved.

FIG. 2 is a flowchart showing the main processing flow when creating a polling transmission file according to the first embodiment for the facsimile apparatus of the present invention. In the figure, # 1 to # 5 indicate steps.

When a polling file is created on the receiving side, as shown in the flow of FIG.
Monitor whether there is an instruction to create a polling transmission file. When a file creation instruction is detected, step # 2 is performed.
Then, enter the telephone number of the other party, and in the next step # 3,
It is stored in the destination number storage unit 11 of FIG. Step # 4
Monitor whether there is an instruction to start reading the original. When the document is set, reading of the document is started, the read image information is stored in the image information storage unit 10 of FIG. 1, and the flow of FIG. 2 is ended. Through the processing in steps # 1 to # 5, the telephone number of the destination and the polling transmission original are stored together.

Next, the operation at the time of polling communication will be described. When the polarity inversion or the start signal of the ID receiving terminal is detected,
The line is closed, the calling ID (telephone number data) is received, and stored and stored in the calling side telephone number storage unit 4 of FIG.
In the first embodiment, the line is temporarily released in this state. Thereafter, when the original call signal (ringing signal) arrives, the line is closed and a secondary response is made. In this case, the caller-side telephone number storage unit 4 shown in FIG.
Is compared with the telephone number of the other party stored in the destination number storage unit 11 of FIG. 1 when the previous polling transmission file is created. If both telephone numbers match as a result of the comparison, the transmission capability bit (for example, the ninth bit) in the frame of the digital identification signal DIS shown in FIG. 12 is set to "1". However, when the two telephone numbers do not match, the transmission capability bit is set to "0" (actually, the status is not changed and is kept as it is). Thereafter, communication starts, but normal reception is possible without setting the transmission capability bit of the signal DIS to "1". The above operation is shown in the flow.

FIG. 3 is a flowchart showing the flow of main processing at the time of polling communication according to the first embodiment for the facsimile apparatus of the present invention. In the figure, # 11 to # 23 indicate steps.

In step # 11, the presence or absence of polarity inversion is monitored. When the polarity inversion is detected, in the next step # 12,
The presence or absence of an activation signal of the ID receiving terminal is monitored. When the activation signal of the ID receiving terminal is detected, the line is closed and a primary response is made in step # 13. In the next step # 14, call I
D (telephone number data) is received. In step # 15,
The received calling ID is stored in the calling side telephone number storage unit 4 of FIG. In step # 16, the line is released. In the next step # 17, the presence or absence of a call signal is monitored. When the call signal is detected, the process proceeds to step # 18, the line is closed, and a secondary response is performed.

At step # 19, the telephone number of the calling party is
Determine whether the telephone number of the other party matches.
When both telephone numbers match, the process proceeds to step # 20, where the bit transmission capability bit of the digital identification signal DIS shown in FIG. 12 is set to "1". On the other hand, if the two telephone numbers do not match, step # 21
Sets the transmission capability bit of the digital identification signal DIS to “0”.
Set to. Thereafter, the process proceeds to step # 22, in which the called terminal identification signal CED is transmitted, and in the next step # 23, the process proceeds to the transmission of the option signal CSI and the digital identification signal DIS.

As described above, in the first embodiment,
The telephone number stored in the calling-side telephone number storage unit 4 in FIG. 1 is compared with the telephone number stored in the destination number storage unit 11 for the called side (transmitting side) to perform polling communication. By setting the transmission capability bit in the frame of the digital identification signal DIS to "1" only when both telephone numbers match, security can be improved as compared with polling communication performed only by the conventional ID comparison. It can be significantly improved.

Second Embodiment This second embodiment corresponds to the invention of claim 2, but also relates to the invention of claim 1. In the first embodiment, the calling ID (telephone number data) notified to the called side is stored, and set when the facsimile apparatus on the called side creates the polling transmission original file (the original destination). After confirming that it matches the ID), the signal D
The case where the transmission capability bit of the IS is set to “1” and transmission is started to prevent erroneous transmission of a polling transmission original and improve reliability has been described. By the way, in the case of the facsimile apparatus described in the first embodiment, V. There is also a model capable of performing the communication with the C.34. This V. 34 communication, first, after connecting the line,
V. 8 communication is specified. And this V. In the 8 communication, V.8 exchanges information of a communicable modem type and a communication direction to each other. 34 communication can be performed smoothly. here,
V. A normal communication flow for communication according to the 34 standard will be described.

FIG. FIG. 3 is a diagram showing an outline of a sequence of polling communication according to the 34 standard. The reference numerals in the figure are the same as those in FIG.

As shown in FIG. In polling communication according to the V.34 standard, after a line connection, 8 is executed, and then the V.8 communication sequence is executed. The sequence of the 34 communication is started. As shown in FIG. Phase 1 of V.34 8 communication and modified response tone ANSam
And ends with signal CJ. During this time, information on the modulation mode and the calling function (including the communication direction) with which the terminals can communicate is exchanged. This V. The call category exchanged in the communication 8 is a call menu signal CM
Alternatively, the common menu signal JM is a signal instructing "calling side reception". In this case, even if there is no calling telephone number and the corresponding polling transmission original,
V. The calling category of the 8 communication is “calling side reception”, and facsimile transmission is started.

Therefore, in the second embodiment, when the telephone number of the calling side and the corresponding polling transmission original do not exist, the V.200 is used. 8 Calling category is "Calling side reception"
It is characterized in that the communication cost is suppressed by controlling the communication not to be performed and disconnecting the line at the initial stage. For example, a calling menu signal C transmitted from the calling side
M informs the user of "reception" and if the called party has a polling transmission document, the called party responds to the "reception" by transmitting the common menu signal JM. In contrast, if the called party does not have a polling transmission manuscript,
"Send" will be returned. However, in this case, since the communication directions are different, it is determined that communication is not possible.

FIG. 5 is a diagram showing an example of allocation of the calling function category and the bits of the function of "calling side transmission" or "calling side reception" for the calling menu signal CM and the common menu signal JM. .

In the case of "calling side transmission" as the category of the calling function, as shown in the upper row of FIG. 5, the 8 bits constituting the calling menu signal CM and the common menu signal JM are: Bits 0 to 7 are set to “1000
0001 ", and in the case of" calling side reception "," 10000101 "is allocated as shown in the lower row of FIG. By making such an assignment, it is possible to clarify whether the calling side "transmits" or the calling side "receives".

FIG. 6 is a flowchart showing a main processing flow in polling communication according to the second embodiment for the facsimile apparatus of the present invention. In the figure, # 31 to # 39 indicate steps.

In step # 31, the presence or absence of a call signal is monitored. When the call signal is detected, the process proceeds to step # 32,
Close the line and make a secondary response. Next step # 33
Then, the ANSam signal is transmitted. In step # 34, it is monitored whether a CM signal has been received from the calling side. When the CM signal is detected, the process proceeds to step # 35, where it is checked whether the called telephone number matches the other party's telephone number. If both phone numbers match, in the next step # 36,
The calling category of the signal JM is set to "calling side reception", and the process proceeds to step # 38. If the two telephone numbers do not match, the process proceeds to step # 37, the calling category of the signal JM is set to "calling side transmission", and similarly, the process proceeds to step # 38. At step # 38, the signal JM is transmitted. In the next step # 39, it is monitored whether or not the signal CJ has been received. When the signal CJ is detected, the flow of FIG. 6 ends.

According to the second embodiment, the destination telephone number stored together with the polling transmission original is
If the received call destination phone number is different, By the end of the eight communications, the fact is transmitted to the calling side, so that useless communication time is reduced and communication costs are reduced.

Third Embodiment This third embodiment corresponds to the invention of claim 3, but also relates to the invention of claim 2. In the second embodiment, when the telephone number of the calling side and the corresponding polling transmission document do not exist, V.P. The calling category of the 8 communications is controlled not to be "calling side reception", and the line is disconnected at an initial stage. In the third embodiment, in the facsimile apparatus described in the second embodiment, It is characterized in that when a difference in the calling category is detected in the eight communications, a process of disconnecting the line is performed on the called side.

FIG. 7 is a flowchart showing the main processing flow of polling communication according to the third embodiment for the facsimile apparatus of the present invention. The reference numerals in the figure are the same as those in FIG. 6, and # 41 to # 43 indicate the added steps.

Also in the third embodiment, step # 3
The processing of 1 to # 39 is the same as that of FIG. The difference between the flow of FIG. 7 and FIG. 6 is that the flow of FIG.
When the signal CJ is detected in step # 39, all the processes are terminated. Thereafter, when the calling category of the signal CM differs from that of the JM, only the process of disconnecting the line on the called side is performed. Therefore, in the flow of FIG. 7, when the signal CJ is detected in step # 39, the process proceeds to step # 41, and it is determined whether or not the calling functions of the CM / JM match. And if the calling function of CM / JM matches,
The process proceeds to step # 42 to continue the communication. Also, CM /
If the calling functions of the JM do not match, the process proceeds to step # 43, the line is disconnected, and the flow of FIG. 7 ends.
As described above, in the third embodiment, the V.V. When the difference in the calling category is detected in the eight communications, the called party performs a process of disconnecting the line. Therefore, it is possible to receive another incoming call, and it is possible to improve the line use efficiency.

Fourth Embodiment The fourth embodiment corresponds to the invention of claim 4, but also relates to the invention of claims 1 to 3.
In the first to third embodiments, when the memory file of the polling transmission original is created, the telephone number of the other party is also stored, so that the telephone number can be compared with the calling telephone number notified from the exchange. However, a case has been described in which transmission is not started when there is a mismatch. This fourth
The embodiment is characterized in that operability is improved by simplifying the input operation of the telephone number of the other party in this case.

FIG. 8 is a diagram for explaining an example of detection of coincidence between a telephone number received from the exchange and a telephone number at the time of creating a memory file for polling transmission according to the fourth embodiment of the present invention. ) Indicates two telephone numbers, and (2) indicates a case in which both are determined to match.

As shown in FIG. 8A, for example, the telephone number sent from the exchange side is "03-5432-".
1234 ", the registered telephone number of the polling transmission original is" 5432-1234 "or" 1234 ".
However, it is possible to perform polling transmission. Therefore, the input of the other party's telephone number for polling transmission is only required for some digits. When a memory file of a polling transmission original is created, a destination telephone number is input. If the telephone number is set to an arbitrary length and the same number sequence is found, it is determined that the numbers match. Therefore, users can tighten security levels,
It can be sweetened. That is, since the operator can select the accuracy, the operability is improved. As described above, in the fourth embodiment, the input operation of the destination telephone number when creating the memory file of the polling transmission original can be made to be a part of the regular number, and is notified from the exchange side. When comparing the calling telephone number with the input telephone number, if the digits of both numbers do not match, the numbers are shifted from the lower digit and compared. Therefore, it is possible to use only a part of the digits of the telephone number, and the operator can select the number of digits according to the degree of the transmission content, so that the operability is improved.

[0052]

According to the facsimile apparatus of the first aspect, the telephone number stored in the calling telephone number storage unit and the destination number storage unit in order for the called side (transmitting side) to perform polling communication. The transmission capability bit in the frame of the digital identification signal DIS is set to "1" only when the two telephone numbers match with each other. Therefore, compared to the conventional polling communication executed only by comparing the ID of the protocol signal SEP, since the polling transmission original is transmitted after confirming the telephone number of the calling side, erroneous transmission is prevented, and the reliability of the apparatus is reduced. The performance is improved.

In the facsimile apparatus according to the second aspect, when the telephone number of the calling side and the corresponding polling transmission original do not exist, the V.F. 8
The calling category of the communication is controlled so as not to be "calling side reception", and the line is disconnected at an initial stage. Therefore, in addition to the effect of the facsimile apparatus of the first aspect, when the destination telephone number stored together with the polling transmission original is different, V.V. Since the communication is transmitted to the calling side by the time the eight communication is completed, the communication time is shortened and the communication cost is reduced.

According to the facsimile apparatus of claim 3, in the facsimile apparatus of claim 2, When the difference in the calling category is detected in the eight communications, the called party performs a process of disconnecting the line. Therefore, in addition to the effect of the facsimile apparatus of claim 2, V.V. When a difference in the calling category is detected in the eight communication, the line can be disconnected on the called side, and another incoming call can be accepted immediately, so that the line utilization efficiency is improved.

In the facsimile apparatus according to the fourth aspect, the input operation of the telephone number of the destination when the memory file of the polling transmission original is created can be made a part of the regular number, and is notified from the exchange. The calling phone number,
When the numbers of both numbers do not match when comparing with the input telephone number, the numbers are shifted from the lower digit and compared. Therefore, it is possible to input the telephone number of the destination of the polling transmission with only some digits of the telephone number, and the operator can select the number of digits according to the degree of the transmission content. The performance is improved.
