[Prior art]
In recent years, this type of facsimile communication apparatus has used an option signal in which information indicating a specific function such as an F code, which is defined in T series recommendation 30 of ITU-T (International Telecommunication Union Telecommunication Standardization Sector), is used. Facsimile communication is being performed.
[0003]
Conventionally, when performing facsimile communication using an option signal such as an F code, a user (operator) designates a destination telephone number registered in an abbreviated dial, and then the F code or the like. The call instruction is given after manually inputting the information of the option signal used in.
[0004]
As described above, in the conventional facsimile apparatus, since only the other party telephone number can be registered in the speed dial, the information of the option signal used in the F code every time communication using the F code is performed. It was necessary for the user to input manually, which was very time consuming and laborious.
[0005]
Further, in the conventional facsimile apparatus, it is required to determine whether or not the user can perform multiple selection polling. Unless the user knows the same function and gives an instruction, the communication to be integrated into the same call is performed multiple times. Since calls were made separately, the communication cost was high.
[0006]
[Problems to be solved by the invention]
As described above, in the conventional facsimile apparatus, every time the user communicates with the partner station registered in the speed dial using an option signal such as an F code, the user receives the option signal. It was necessary to input information to be set in, and it took a lot of time and effort.
[0007]
Also, in the conventional facsimile apparatus, when a call instruction using a plurality of different option signals is given to the other party registered in the speed dial, the user makes his / her own judgment and the same, such as multiple selection polling Unless there is an instruction to combine the calls, the communication cost is high because communication is performed for each option signal for each option signal.
[0009]
Therefore, in the present invention, even if the above problem is eliminated and the user is not aware of it, depending on the capability of the partner station, instructions for a plurality of specific functions are combined into the same call, and the operations of the specific functions are combined into the same call. It is an object of the present invention to provide a facsimile communication apparatus that can reduce the communication cost by processing in the network.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the invention described in claim 1 has registration means for registering in the speed dial by associating specific function information set in the option signal with destination information of the counterpart station, In a facsimile communication apparatus having a function of communicating with a partner station using an option signal in which information indicating a specific function to be registered is set, each of the abbreviated dials is instructed by a plurality of different abbreviated dials. Comparing the destination information of the other destination stations and determining whether or not a call instruction for the other station of the same destination information is included, and by the determination means, a call instruction for the other station of the same destination information For each option signal registered for each speed dial having the same destination information. Characterized by comprising a communication control means for controlling so as to communicate without communication interruption.
[0011]
The invention according to claim 2 further comprises registration means for registering in the abbreviated dial by associating the destination information of the partner station with the specific function information set in the option signal, and the specific function registered in the abbreviated dial. In a facsimile communication apparatus having a function of performing communication with a partner station using an option signal in which information indicating the destination is indicated, when a call instruction is issued by a plurality of different speed dials, destination information of the partner station of each speed dial The first determination means for determining whether or not a call instruction for the counterpart station with the same destination information is included, and the call instruction for the counterpart station with the same destination information by the first determination means If multiple specific function information to be set in a plurality of option signals registered for each speed dial having the same destination information is selected and specified. It is determined that a plurality of specific function information to be set for a plurality of option signals registered for each speed dial having the same destination information has been selected and specified by the second determination means for determining whether or not Communication control means for making a call to the counterpart station of the same destination information and controlling to communicate without disconnecting for each of the plurality of option signals selected and specified.

When a call instruction is issued, the calling station sends a call signal to the called station having the destination telephone number information “03-1234-1234” to make a call (Calling).
[0032]
On the other hand, the called station transmits a digital identification signal (DIS) indicating the full capability of the called station to the calling station. At the same time, a non-standard function identification signal (NSF) and a called terminal identification signal (CSI) may be transmitted as option signals to the calling station.
[0033]
Since the calling station that has received the DIS signal performs confidential transmission at this time, the function used for confidential transmission is selected from the capabilities indicated by the DIS signal, and the function is sent to the called station by a digital command signal (DCS). The function box number is set in the SUB frame and transmitted to the called station. In this embodiment, “12345” is set in the SUB FIF. After the DCS signal is transmitted, a training signal (TCF) for adjusting the inter-modem is transmitted to switch to the high-speed modem.
[0034]
The called station on the receiving side has SUB compatibility such as whether the box number set in the SUB frame received from the calling station is registered or whether image information can be stored in the designated box. Judgment is accepted, and if it is determined to be compatible, reception is accepted. When the modem adjustment is completed, a reception preparation confirmation signal (CFR) indicating that the message is ready to be received is transmitted to the calling station.
[0035]

[0076]
FIG. 12 is a sequence diagram showing a communication procedure between the calling station and the called station when a call instruction for confidential polling is performed using the selection screen 305 shown in FIGS. 10 and 11. This example shows a case where the facsimile apparatus is applied to the calling station side and the called station side has a multi-select polling capability.
[0077]
In FIG. 12, when a user issues a call instruction in multi-select polling communication that specifies speed dial information input and set on the speed dial setting screen 304 (see FIG. 9), the calling station Then, a call signal is transmitted to the called station to make a call.
[0078]
On the other hand, the called station transmits a DIS indicating the full capability of its own station to the calling station. At this time, the called station sets information indicating “with multi-select polling capability” in this DIS signal. At this time, there are cases where NSF and CSI are transmitted as an option signal to the instruction station.
[0079]
At this time, the calling station that has received the DIS signal performs multi-selection polling, and therefore transmits a digital transmission command signal (DTC) containing information declaring that multi-selection polling is performed to the called station. The subaddress information “12345” is set in the SEP1 frame FIF and transmitted to the called station. At the same time, CIG may be transmitted to the called station as an option signal.
[0080]
On the other hand, the called station on the transmitting side determines the suitability of SEP1 such as whether or not the subaddress information “12345” set in the SEP1 frame received from the calling station is registered, and is compatible. If it is determined, confidential polling from the calling station is accepted. Then, a function used for transmission is selected from the capabilities indicated by the received DTC signal, and the function is designated to the calling station by DCS. In some cases, TSI is transmitted to the calling station as an optional signal before DCS. Then, after transmitting the DCS signal, a TCF for adjusting between modems is transmitted to switch to a high-speed modem.
[0081]
The calling station on the receiving side normally receives the TCF, and after completing the modem adjustment, sends a CFR indicating that the message is ready to be received to the called station.
[0082]
On the other hand, when the called station on the transmitting side receives the CFR, the transmission original in the function box corresponding to the subaddress information “12345” designated by the SEP1 frame is transferred in page units using the high-speed modem. Image information (PIX) is transmitted to the calling station. When the transmission of the document ends, a selection end signal (EOS) is transmitted to the calling station, and the process proceeds to the next document transmission procedure.
[0083]
Upon receiving the EOS signal, the calling station transmits an MCF signal to the called station for confirmation. After that, the calling station transmits a DTC signal to the called station after a certain time has elapsed (T2Timeout), and sets the subaddress information “56789” in the SEP2 frame FIF and transmits it to the called station. . At the same time, CIG may be transmitted to the called station as an option signal.
[0084]
On the other hand, the called station determines the suitability of SEP2, such as whether or not the sub-address information “56789” set in the SEP2 frame received from the calling station is registered, Accept confidential polls from the calling station. Then, a function used for transmission is selected from the capabilities indicated by the received DTC signal, and the function is designated to the calling station by DCS. In some cases, TSI is transmitted to the calling station as an optional signal before DCS. Then, after transmitting the DCS signal, a TCF for adjusting between modems is transmitted to switch to a high-speed modem.
[0085]
The calling station normally receives the TCF and, after completing the modem adjustment, sends a CFR indicating that the message is ready to be received to the called station.
[0086]
On the other hand, when the called station receives the CFR, the document in the function box corresponding to the subaddress information “56789” designated by the SEP2 frame is transferred to the page unit image information (PIX) using the high-speed modem. To the calling station. When the transmission of the document is completed, an EOP indicating that the transferred page is the last page is transmitted to the calling station.
[0087]
Upon receiving the EOP signal, the calling station transmits an MCF signal to the called station for confirmation.
[0088]
Upon receiving the MCF signal, the called station transmits a DCN signal indicating disconnection to the calling station, and proceeds to a procedure for disconnecting this communication.
[0089]
As a result, the calling station of the facsimile apparatus 100 can execute the multiple selection polling within the same call without releasing the line once with the called station having the multiple selection polling capability.
[0090]
FIG. 13 is a sequence diagram showing a communication procedure between a calling station and a called station when a call instruction for confidential polling is performed using the selection screen 305 shown in FIGS. 10 and 11. This example shows a case where the facsimile apparatus is applied to the calling station side and the called station side does not have the multi-select polling capability.
[0091]
In FIG. 13, when a user issues a call instruction in multi-select polling communication in which speed dial information input and set on the speed dial setting screen 304 (see FIG. 9) is specified, the calling station Then, a call signal is transmitted to the called station to make a call.
[0092]
On the other hand, the called station transmits a DIS indicating the full capability of its own station to the calling station. At this time, since the called station does not have the multi-select polling capability, information indicating “multi-select poll capability is present” is not set in the DIS signal. At this time, there are cases where NSF and CSI are transmitted as an option signal to the instruction station.
[0093]
At this time, the calling station that has received the DIS signal performs confidential polling. Therefore, the calling station transmits DTC including information declaring that confidential polling is performed to the called station, and transmits subaddress information “12345” to the SEP1 frame. Is transmitted to the called station. At the same time, CIG may be transmitted to the called station as an option signal.
[0094]
The called station on the transmitting side determines the suitability of SEP1 such as whether or not the subaddress information “12345” set in the SEP1 frame received from the calling station is registered. Accept confidential polls from the calling station. Then, a function used for transmission is selected from the capabilities indicated by the received DTC signal, and the function is designated to the calling station by DCS. In some cases, TSI is transmitted to the calling station as an optional signal before DSC. Then, after transmitting the DCS signal, a TCF for adjusting between modems is transmitted to switch to a high-speed modem.
[0095]
The calling station on the receiving side normally receives the TCF, and after completing the modem adjustment, sends a CFR indicating that the message is ready to be received to the called station.
[0096]
On the other hand, when the called station on the transmitting side receives the CFR, the transmission original in the function box corresponding to the subaddress information “12345” designated by the SEP1 frame is transferred in page units using the high-speed modem. Image information (PIX) is transmitted to the calling station. When transmission of the document in the box ends, a procedure end signal (EOP) indicating that the transferred page is the last page is transmitted to the calling station.
[0097]
Upon receiving the EOP signal, the calling station transmits an MCF signal to the called station for confirmation.
[0098]
Upon receiving the MCF signal, the called station transmits a DCN signal indicating disconnection to the calling station, and shifts to a procedure for once disconnecting this communication.

Thereafter, the calling station transmits a call signal to the called station again to make a call. That is, another call is made.
[0101]
On the other hand, the called station transmits a DIS indicating the full capability of its own station to the calling station. At this time, there are cases where NSF and CSI are transmitted as an option signal to the instruction station.
[0102]
Since the calling station that has received the DIS signal performs confidential polling at this time, it transmits a DTC containing information declaring that confidential polling is performed to the called station, and subaddress information “56789” as SEP2 frame. Is transmitted to the called station. At the same time, CIG may be transmitted to the called station as an option signal.
[0103]
The called station determines the suitability of SEP1 such as whether or not the sub-address information “12345” set in the SEP2 frame received from the calling station is registered. Accept confidential polls from. Then, a function used for transmission is selected from the capabilities indicated by the received DTC signal, and the function is designated to the calling station by DCS. In some cases, TSI is transmitted to the calling station as an optional signal before DCS. Then, after sending out the DCS signal, it sends out a TCF for inter-modem adjustment in order to switch to a high-speed modem.
The calling station normally receives the TCF and, after completing the modem adjustment, sends a CFR indicating that the message is ready to be received to the called station.
[0104]
On the other hand, when the called station receives the CFR, the document in the function box corresponding to the subaddress information “56789” designated by the SEP2 frame is transferred to the page unit image information (PIX) using the high-speed modem. To the calling station. When the transmission of one page of PIX is completed, in this example, an EOP indicating that the transferred page is the last page is transmitted to the calling station.
[0105]
Upon receiving the EOP signal, the calling station transmits an MCF signal to the called station for confirmation.
[0106]
Upon receiving the MCF signal, the called station transmits a DCN signal indicating disconnection to the calling station, and proceeds to a procedure for disconnecting this communication.
[0107]
As described above, if the called station does not have the capability of multiple selection polling, even if the other party (destination) is the same, polling communication between the calling station and the called station is performed once. After disconnecting, another poll is performed with another call.
[0108]
In the sequence diagrams shown in FIGS. 12 and 13, a plurality of option signals set for one abbreviated number among the abbreviated dials set and registered using the abbreviated dial setting screen 304 in FIG. When a call is instructed by selecting information, FIG. 12 performs multiple selection polling within the same call without releasing the line once with a called station having multiple selection polling capability. FIG. 13 shows a communication procedure to be performed. If the called station side does not have the capability of multiple selection polling, even if the other party (destination) is the same, once between the calling station and the called station, A communication procedure for performing another polling with another call after the polling communication is disconnected is shown. However, the present invention is not limited to this. For example, by using the speed dial setting screen 304 of FIG. 9 described above, only information that is set as an option signal with the same destination information (partner telephone number) for different speed dial numbers. Even when a plurality of items having different numbers are registered and a call instruction is made using information on a plurality of speed dial numbers in which the same destination information is registered, the sequence shown in FIG. 12 and FIG. Similarly, a communication procedure for performing multi-selection polling within the same call without releasing the line once is performed with a callee having multi-selection polling capability. If there is not, a communication procedure is executed in which the polling communication between the calling station and the called station is once disconnected and then another polling is executed with another call.
[0109]
Similarly, in the present invention, using the abbreviated dial setting screen 301 in FIG. 2 and the abbreviated dial setting screen 302 in FIG. 5, the same destination information (destination telephone number) is used as an option for different abbreviated dial numbers. Even when a plurality of items that differ only in the information to be set in the signal are registered and a call instruction is issued using information of a plurality of speed dial numbers in which the same destination information is registered, Similar to the sequence shown in FIG. 12 and FIG. 13, a communication procedure for performing multiple selection polling within the same call without releasing the line once is performed with the called station having the multiple selection polling capability. If the station does not have the ability to perform multi-select polling, the communication procedure is to disconnect the polling communication between the calling station and the called station once and then perform another polling with another call. And Umono.
[0110]
Furthermore, each time a call is made by the user without using the speed dial, even if multiple destination information (partner phone number) and option signal information are specified, the destination information must be the same. For example, similar to the sequence shown in FIG. 12 and FIG. 13, a communication procedure for performing multiple selection polling within the same call without releasing the line once is performed with a called station having multiple selection polling capability. If the called station does not have the ability to perform multi-select polling, a communication procedure is performed in which the polling communication between the calling station and the called station is once disconnected and then another polling is performed with another call.
