[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a facsimile apparatus that performs polling transmission. 8 standard and V.I. The present invention relates to a facsimile apparatus that performs 34 standard communication or a communication apparatus that incorporates this facsimile function.
[0002]
[Prior art]
  Regarding the facsimile apparatus, various standards are defined by the CCITT recommendation. 8 standard (V.8 mode), V.8. 21 standard (V.21H mode), V.21. The communication control procedure for communication is defined for modems such as the 34 standard (V.34 mode) [For example, ITU-T, V series (modem related etc.) recommendations, 1994, New Japan ITU Association Issue〕. By using a facsimile machine equipped with a modem that complies with the communication control procedure defined in this CCITT recommendation (especially recommendation T.30), it is possible to communicate between modems of different standards.
[0003]
  When performing polling communication, first, the call side notifies the calling side by a protocol signal that the polling transmission original (or the memory file storing the polling transmission original) is ready. Further, the transmission of the transmission document is started by requesting polling reception from the calling side which has received this notification. After the start of polling communication, the caller side can be confirmed by communication of the protocol signal SEP in the standard protocol. However, when a plurality of polling transmission originals are stored in a memory file and the destinations of the transmission originals are different, there is a limit even if the ID included in the protocol signal SEP is changed. , There is a possibility of erroneous transmission to a destination whose IDs coincided by chance. For this reason, there is a problem in that confidentiality cannot be completely maintained and the reliability of polling communication is lowered.
[0004]
  In order to solve such a problem, in recent years, an exchange having a function of notifying a caller's telephone number to a callee has been developed, and a subscriber service is scheduled to start. As a technique using such a function, there is known an incoming call control system that uses an outgoing ID (telephone number data) and displays the presence / absence of an incoming call and the outgoing ID on a receiving terminal when busy (for example, special features). (Kaihei 6-152753). This incoming call control method 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 number notification device that outputs a second call signal according to the caller ID is also known (for example, Japanese Patent Laid-Open No. 4-34952). This caller ID notification device is also one of applications using the caller ID, but does not consider the point of improving the reliability of polling communication. Here, polling communication will be described.
[0005]
  FIG. 9 is a diagram showing an outline of a sequence of normal polling communication. In the figure, the upper column is the calling side (receiving side), the lower column is the called side (transmitting side), CED, CSI, DIS, CIG, DTC, TSI, DCS, TCF, CFR, PIX, PPS-EOP, MCF and DCN indicate signals.
[0006]
  In the sequence of FIG. 9, since the polling ID is not communicated, anyone can receive the polling document set on the called side although it is simple. Therefore, there is no security and confidentiality cannot be maintained. In order to cope with such a problem, polling communication with ID is defined.
[0007]
  FIG. 10 is a diagram showing an outline of a 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 a protocol signal.
[0008]
  A frame of the protocol signal SEP is added to the sequence shown in FIG. Then, using the ID in the frame of the protocol signal SEP, it is possible (permitted) to perform polling transmission only to a specific destination. In this case, if the IDs do not match, the line is immediately disconnected.
[0009]
  FIG. 11 is a diagram showing an outline of a sequence when IDs are different in the polling communication with ID shown in FIG. The reference numerals in the figure are the same as those in FIG.
[0010]
  As a result of comparing the IDs in the frame of the protocol signal SEP, 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 the normal polling communication shown in FIG. However, even if this method is adopted, since the ID can be arbitrarily set, there may be a case where the IDs coincide by chance. In addition, a method using a frame of the digital identification signal DIS is also known in order to avoid meaningless polling communication and reduce communication costs.
[0011]
  FIG. 12 is a diagram showing bit assignment of the digital identification signal DIS. FIG. 12 shows the head part of the digital identification signal DIS. Information indicating that transmission is possible is assigned to the 9th bit (bit No. 9), and information indicating that reception is possible is assigned to the next 10th bit. It has been. When there is a document that can be transmitted to the receiving side, the corresponding bit is set to “1”. That is, when the polling transmission document is set on the called side or when there is a polling transmission memory file, the 9th transmittable bit shown in FIG. 12 is set.
[0012]
  FIG. 13 is a diagram showing an outline of a sequence in the case where the line is disconnected 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.
[0013]
  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 generates a disconnect command signal DCN when detecting that the bit is not set. And disconnect the line.
[0014]
  FIG. 14 is a diagram showing an outline of the sequence of the calling telephone number notification from the exchange side. The reference numerals in the figure are the same as those in FIG.
[0015]
  In the sequence shown in FIG. 14, a communication sequence part of the telephone number on the calling side sent from the exchange side is added. When the calling party makes a call, first the polarity reversal occurs at the called party. Thereafter, when an ID receiving terminal activation signal arrives and the called terminal connects and responds, the calling ID (telephone number data) becomes V.25. It is transmitted according to the 23 standard. When reception is completed at the called terminal, the line is released. Then, when the original call signal (ringing signal) is sent and the called terminal responds by closing the line, communication is started.
[0016]
[Problems to be solved by the invention]
  As described in the related art, many countermeasures have been proposed for polling communication in order to prevent erroneous transmission of a transmission document and improve reliability. In addition, devices and methods for informing the caller of the telephone number of the caller have been developed. However, a reliable method and apparatus for maintaining confidentiality (increasing security) in polling communication has not yet been proposed. It is an object of the present invention to maintain confidentiality in polling communication and improve communication reliability.

[0027]
  First embodiment
  The first embodiment corresponds to the invention of claim 1, but is also related to the inventions of claims 2 to 4, and the invention of claim 1 is a basic invention. In the first embodiment, in order to maintain confidentiality in polling communication (increase security), not only the ID in the frame of the protocol signal SEP but also the telephone number on the calling side is confirmed together It is characterized in that transmission of a polling transmission document is started.
[0028]
  As shown in FIG. 14 above, a communication method in which a telephone number on the calling side is transmitted from the exchange side and a response or non-response is determined on the called side using this telephone number (calling ID) has already been established. Proposed. In the case of this communication system, the line is temporarily opened after receiving the telephone number on the calling side sent from the exchange side. In this first embodiment, the received telephone number of the calling party is held, and when the line is closed by the next calling signal, the telephone number of the calling party previously held is held. Determines whether the destination telephone number in the polling transmission file created on the called side matches. As a result of comparison, if the caller's telephone number matches the other party's telephone number set in the polling transmission document, the ninth bit (bit No. 9) of the digital identification signal DIS shown in FIG. The information indicating that transmission is possible assigned to (1) is set to “1”. This 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 party desires polling communication. It is not possible. Normally, the information indicating that the 9th bit of the digital identification signal DIS can be transmitted is set to “0” when there is no telephone number on the calling side and no polling transmission document corresponding to the telephone number. Set. However, in this first embodiment, the caller's telephone number that holds the information indicating that transmission is possible matches the destination telephone number of the polling transmission file created on the called party's side. After confirming that it is set to “1”, erroneous transmission is prevented and reliability is remarkably improved.YouThe
[0029]
  FIG. 2 is a flowchart showing a main processing flow when creating a polling transmission file according to the first embodiment of the facsimile apparatus of the present invention. In the figure, # 1 to # 5 indicate steps.
[0030]
  When creating a polling file on the called side, as shown in the flow of FIG. 2, the presence or absence of an instruction for creating a polling transmission file is monitored in step # 1. When a file creation instruction is detected, the telephone number of the other party is input in step # 2, and stored in the other party number storage unit 11 of FIG. 1 in the next step # 3. In step # 4, the presence / absence of an instruction to start reading a document is monitored. When the original is set, reading of the original 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 processes in steps # 1 to # 5, the destination telephone number and the polling transmission document are stored together.
[0031]
  Next, the operation during polling communication will be described. When the polarity inversion or the activation signal of the ID receiving terminal is detected, the line is closed and the calling ID (phone number data) is received and stored in the calling side telephone number storage unit 4 of FIG. In this first embodiment, the line is once 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 destination telephone number received in advance and held in the calling side telephone number storage unit 4 in FIG. 1 and the destination number storage unit 11 in FIG. Compare the phone number of the other party stored in. As a result of comparison, if both telephone numbers match, 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, if both telephone numbers do not match, this transmission capability bit is set to “0” (actually unchanged, but kept as it is). Thereafter, communication is started, 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.
[0032]
  FIG. 3 is a flowchart showing a main processing flow at the time of polling communication according to the first embodiment of the facsimile apparatus of the present invention. In the figure, # 11 to # 23 indicate steps.
[0033]
  In step # 11, the presence or absence of polarity inversion is monitored. When polarity inversion is detected, the presence or absence of the activation signal of the ID receiving terminal is monitored in the next step # 12. When the activation signal of the ID receiving terminal is detected, in step # 13, the line is closed and a primary response is made. In the next step # 14, the calling ID (phone number data) is received. In step # 15, the received call ID is stored in the caller 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, where the line is closed and a secondary response is made.
[0034]
  In step # 19, it is determined whether or not the calling party telephone number matches the other party's telephone number. If both telephone numbers match, the process proceeds to step # 20, and the bit transmission capability bit of the digital identification signal DIS shown in FIG. 12 is set to “1”. On the other hand, when both telephone numbers do not match, the transmission capability bit of the digital identification signal DIS is set to “0” in step # 21. Thereafter, the process proceeds to step # 22, where the called terminal identification signal CED is transmitted. In the next step # 23, the process proceeds to transmission of the option signal CSI and the digital identification signal DIS, and communication is performed in the same procedure as before.
[0035]
  As described above, in the first embodiment, the telephone number stored in the calling side telephone number storage unit 4 in FIG. 1 and the called party number for the calling side (sending side) to perform polling communication are used. Comparison with the conventional ID by comparing the telephone number stored in the storage unit 11 and setting the transmission capability bit in the frame of the digital identification signal DIS to “1” only when both telephone numbers match. As compared with polling communication executed by itself, security can be remarkably improved.
[0036]
  Second embodiment
  The 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 party is stored and set at the time of creating the polling transmission document file in the called facsimile machine (original party) After confirming that the ID matches the previous ID, the transmission capability bit of the signal DIS is set to “1” to start transmission, thereby preventing erroneous transmission of the polling transmission original and improving reliability. Explained. By the way, in the case of the facsimile apparatus described in the first embodiment, V. There are also models capable of 34 communication. This V. 34 communication, first, after the line connection, V. It is prescribed to perform 8 communications. And this V. In the 8 communication, the information on the modem type and the communication direction that can be communicated with each other is exchanged. 34 communication can be executed smoothly. Here, V. A normal communication flow for communication according to the 34 standard will be described.
[0037]
  FIG. It is a figure which shows the outline | summary of the sequence about the polling communication by 34 standards. The reference numerals in the figure are the same as those in FIG.
[0038]
  As shown in FIG. In polling communication according to the 34 standard, V. 8 communication sequence is executed. 34 communication sequence is started. As shown in FIG. Phase 1 of 34 is V.40. 8 communications, starting with the deformation response tone ANSam and ending with the signal CJ. During this time, information on the modulation mode and calling function (including the communication direction) in which the terminals can communicate with each other is exchanged. This V. In the calling category exchanged by 8 communications, the calling menu signal CM or the common menu signal JM is a signal for instructing “calling side reception”. In this case, even when there is no calling side telephone number and corresponding polling transmission document, V. The call category of 8 communication becomes “calling side reception” and facsimile transmission is started.
[0039]
  Therefore, in the second embodiment, if there is no calling side telephone number and the corresponding polling transmission document, V. It is characterized in that the communication cost is controlled by controlling the calling category of 8 communication not to be “calling side reception” and disconnecting the line at the initial stage. For example, if the calling menu signal CM transmitted from the calling side notifies that the user wants to “receive” and there is a polling transmission document on the called side, the called side sends “common menu signal JM” to “ Respond to "receive". On the other hand, if there is no polling transmission document on the called side, “transmission” is returned. However, in this case, since the communication direction is different, it is determined that communication is impossible.
[0040]
  FIG. 5 is a diagram showing an example of the allocation of the function of the calling function category and the function of “calling side transmission” or “calling side reception” for the calling menu signal CM and the common menu signal JM.
[0041]
  In the case of “calling side transmission” as the category of the calling function, as shown in the upper row of FIG. 5, the bit 0 of the 8 bits constituting the calling menu signal CM and the common menu signal JM. In the case of “10000001” and “calling side reception”, “10000101” is assigned as shown in the lower row of FIG. By performing such allocation, it is possible to clarify whether the calling side “transmits” or the calling side “receives”.
[0042]
  FIG. 6 is a flowchart showing the main processing flow during polling communication according to the second embodiment of the facsimile apparatus of the present invention. In the figure, # 31 to # 39 indicate steps.
[0043]
  In step # 31, the presence / absence of a call signal is monitored. When the call signal is detected, the process proceeds to step # 32 where the line is closed and a secondary response is made. In the next step # 33, an ANSam signal is transmitted. In step # 34, the presence / absence of reception of a CM signal from the calling side is monitored. When the CM signal is detected, the process proceeds to step # 35 to check whether the called telephone number matches the other party's telephone number. If both telephone 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 both 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. In step # 38, the signal JM is transmitted. In the next step # 39, the presence / absence of the signal CJ is monitored. When the signal CJ is detected, the flow of FIG. 6 ends.
[0044]
  According to the second embodiment, when the destination telephone number stored together with the polling transmission document is different from the received telephone number of the call destination, V.E. Since the fact is transmitted to the calling side by the end of 8 communications, useless communication time is shortened and communication cost is reduced.
[0045]
  Third embodiment
  The third embodiment corresponds to the invention of claim 3 but also relates to the invention of claim 2. In the second embodiment, when there is no calling side telephone number and the corresponding polling transmission document, V. The call category of 8 communication is controlled not to be “calling side reception”, and the line is disconnected at the initial stage. In the third embodiment, in the facsimile apparatus described in the second embodiment, V. A feature is that when a call origination category difference is detected in 8 communications, a process of disconnecting the line is performed on the called side.
[0046]
  FIG. 7 is a flowchart showing a main processing flow at the time of polling communication according to the third embodiment of the facsimile apparatus of the present invention. The reference numerals in the figure are the same as in FIG. 6, and # 41 to # 43 indicate added steps.
[0047]
  Also in the third embodiment, the processes from step # 31 to # 39 are the same as those in FIG. The flow of FIG. 7 is different from that of FIG. 6. In the flow of FIG. 6, when the signal CJ is detected in step # 39, all processing is completed, but thereafter the calling categories of the signals CM and JM are different. Sometimes, the incoming call side only needs to disconnect the line. 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 CM / JM match. If the calling functions of CM / JM match, the process proceeds to step # 42 and communication is continued. If the calling functions of CM / JM do not match, the process proceeds to step # 43, the line is disconnected, and the flow of FIG. As described above, in the third embodiment, V.D. When a difference in calling category is detected in 8 communications, a process for disconnecting the line is performed on the called side. Therefore, it is possible to receive other incoming calls, and the line utilization efficiency can be improved.
[0048]
  Fourth embodiment
  The fourth embodiment corresponds to the invention of claim 4, but also relates to the inventions of claims 1 to 3. In the first to third embodiments, when the memory file of the polling transmission document is created, the telephone number of the other party is also stored together with the calling party telephone number notified from the exchange side. In the case of the mismatch, the case where the transmission is controlled not to start has been described. The fourth embodiment is characterized in that the operability is improved by simplifying the input operation of the telephone number of the other party in this case.
[0049]
  FIG. 8 is a diagram for explaining an example of detecting coincidence between the telephone number received from the exchange side and the telephone number at the time of creating the polling transmission memory file in the fourth embodiment of the present invention. One phone number, (2) shows the case where both are judged to match.
[0050]
  As shown in FIG. 8 (1), for example, when the telephone number sent from the exchange side is “03-5432-1234”, the registered telephone number of the polling transmission document is “5432-1234”, or “1234” can also perform polling transmission. For this reason, it is only necessary to input a part of the digits of the destination telephone number for polling transmission. When creating a memory file for a polling transmission document, the destination telephone number is input. If this telephone number is set to an arbitrary length and a portion of the same number string is found, it is determined that the numbers match. Therefore, the user can make the level of security stricter or 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 document can be made a part of the regular number and notified from the exchange side. When comparing the calling party telephone number and the input telephone number, if the digits of both numbers do not match, the numbers are compared by shifting from the lower digit. Therefore, it is possible to complete only a part of the digits of the telephone number, and the operator can select the number of digits according to the degree of transmission contents, thus improving the operability.YouThe
