DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a communication terminal device, a communication server device, and a terminal information registration method according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0018]
First, FIG. 1 shows a connection between a facsimile apparatus (FAX) 20 as a communication terminal apparatus according to the present invention and a FAX server 31 as a communication server apparatus according to the present invention via a line network. Via a local area network LAN, a communication terminal such as a PC (personal computer) 32 (terminal address 001), 35 (terminal address 002), a printer 33 (terminal address 012), a FAX 34 (terminal address 000), or other not shown 2 shows a communication terminal network (LAN) 30 configured to be connected to the communication terminals of FIG. The LAN 30 is managed by the network server 36.
[0019]
With this configuration, conventionally, in order for the FAX 20 to transmit data to a communication terminal on the LAN 30, first, the FAX 20 is used in the destination number of the FAX server on the LAN via the line network, that is, the line network. By calling the subscriber number, the FAX server 31 is called to transmit data to be transmitted to the communication terminal. At this time, in order to transmit data from the FAX 20 to a specific communication terminal on the LAN 30, it is desired to transmit data by attaching the terminal address number in the LAN 30 of the communication terminal to which data is to be transmitted to the data and notifying the FAX server. A communication terminal is designated to the FAX server 31. The FAX server 31 transfers the data to the communication terminal having the designated terminal address number after the data reception is completed. As a method for sending the data of the terminal address number of the communication terminal, a method of putting it in the sending terminal identification TSI or sending it as a DTMF signal is known.
[0020]
FIG. 2 shows the configuration of the FAX 20 as a communication terminal apparatus according to the present invention. In the figure, a scanner 1 reads a document image and outputs image data, and a plotter 2 records and outputs received image data and image data read by the scanner 1. The display unit 3 displays the operation state of the apparatus and various messages. The operation unit 4 is provided with various keys and accepts operation inputs from the operator.
[0021]
FIG. 3 shows an arrangement example of the display unit 3 and the operation unit 4. In the figure, the display unit 3 includes a display 3a. The display 3a has a touch panel function known per se. When an operator touches a specific position on the displayed selection screen, the selection item displayed at the specific position can be selected. The operation unit 4 includes a numeric keypad 4a, a stop key 4d, and a start key 4e. With these keys, basic operations such as input of a destination number, start of transmission, and interruption of transmission can be performed. Various registration operations including a registration operation according to the present invention and a selection operation can be performed by using the Yes key 4b, the No key 4c, the function key 4f, the cursor key 4g, and the display 3a of the display unit 3.
[0022]
In FIG. 2, the encoding / decoding unit 5 encodes and compresses transmission image data, and decodes and expands reception image data. The MPU 6 controls each part of the apparatus according to a program stored in a built-in ROM (not shown). The registration management memory 7 stores the registration contents of the one-touch dial.
[0023]
The FDD 8 is a floppy disk drive for transferring text files. When text data is selected as transmission data at the time of data transmission, the FAX 20 reads the data recorded on the floppy disk inserted in the FDD 8 and transmits it to the partner apparatus. In the facsimile apparatus, as a procedure for transmitting binary data such as text data instead of a facsimile message, the ITU-T recommendation T.30. The file transfer function of BFT (Binary File Transfer) defined in 30 “Transmission Procedure for Document Transmission Facsimile on Telephone Type Line” can be used.
[0024]
The modem 9 modulates the transmission signal and demodulates the reception signal. The network control device 10 performs line connection control. The system bus 11 is used for the above units to exchange data.
[0025]
With the above configuration, the FAX 20 transmits a facsimile message and text data to a normal communication terminal device connected to the line network as necessary. In addition, for ordinary communication terminal devices connected to the network, data can be transmitted simply by specifying the other party number of the communication terminal device and making a call. Is registered in association with a destination designation operation such as one-touch dialing, the destination number can be designated with fewer key operations than designation with the numeric keypad operation, and an erroneous designation is less likely to occur.
[0026]
However, in order for the FAX 20 to transmit data to a communication terminal on the LAN 30, it is necessary to register and manage not only the destination number of the FAX server 31 but also the terminal address of the communication terminal and information regarding the terminal. Specifically, in order to register a communication terminal on the LAN 30 in the one-touch dial, at least the destination number (subscriber number in the network) of the FAX server 31 and the terminal address are made to correspond to the one-touch dial number. Must be registered. Also, to improve the convenience of one-touch dialing Me In addition, it is necessary to store information (terminal information) related to the communication terminal in association with the one-touch dial number.
[0027]
FIG. 4 shows an example of registration in the registration management memory 7 of the communication terminal when the registered partner is a FAX server on the LAN 30. In the figure, the terminal address on the LAN 30 and the information such as the terminal name and terminal type corresponding to the terminal address are registered. In the example of FIG. 4, there are 13 communication terminals on the LAN 30, FAX is assigned to 000, and other terminals are assigned to 001 to 012.
[0028]
Terminal address numbers 997 to 999 are assigned to a broadcast group, and data can be sent to all communication terminals 000 to 012 or a plurality of designated terminals by selecting the broadcast group. The terminal registration name indicates the name (for example, section, personal name, etc.) registered with the other party, and the terminal type indicates whether the terminal is a PC, a FAX, or a printer.
[0029]
The data type indicates the type of data (PC text data or FAX data) that can be handled by the communication terminal. In FIG. 4, the communication terminal with terminal address 000 can handle only FAX data, and the terminal address 001 can handle both text / FAX data with a PC, but the communication terminals with terminal addresses 002 and 003 can handle only text data with a PC.
[0030]
FIG. 5 shows a method of specifying a communication terminal on the LAN 30 as a data transmission destination in the FAX 20. In the figure, a list of terminal information of the communication partner apparatus is normally displayed on the display 3a of the display unit 3 as shown in the screen 1. In the list, FAX servers are registered in one-touch numbers 2 and 30, and normal communication terminal devices are registered in other cases.
[0031]
As described above, the display 3a has a touch panel function. By touching (PUSH) a predetermined one-touch number area on the screen 1, the one-touch number is selected, and a corresponding partner number can be designated by one touch.
[0032]
If the other party is not a FAX server but a normal communication terminal device, the other party can be specified only by a selection operation in the display state of screen 1. On the other hand, when the destination apparatus is a FAX server, as described above, data cannot be transmitted to the communication terminal on the LAN 30 only by specifying the destination number of the FAX server.
[0033]
Therefore, in the present embodiment, when the FAX server is designated in the display state of screen 1 (for example, one-touch number 2), the display state of display 3a is switched to screen 2. The display contents of this screen 2 are based on the registration contents of the registration management memory 7 shown in FIG.
[0034]
The operator of the FAX 20 can designate a communication terminal to which data is to be transmitted by touch-designating the terminal address (terminal NO) on the screen 2. In other words, data is sent to the general affairs department's PC by two partner designation operations such as touching the one-touch number 2 on the screen 1 and touching the terminal address (terminal NO) 001 on the screen 2. Can do. In other words, a specific communication terminal is associated with the partner designation operation performed only twice.
[0035]
Further, in order to designate a specific communication terminal on the screen 2, it is sufficient to display a terminal address (terminal NO) as a minimum. In the present embodiment, it is further desired to display a terminal name and transmit it. It is possible to prevent specification mistakes when specifying the communication terminal of the other party. Also, by displaying the terminal type, it is possible to know the type of the communication terminal of the other party, thereby further preventing the designation error of the other party.
[0036]
Further, although not displayed on the screen shown in FIG. 5, if the data format of the registration contents of the registration management memory 7 shown in FIG. It is possible to check whether the data format of the data to be transmitted matches the data format that can be handled by the communication terminal of the transmission partner, and the data partner does not match. It is possible to prevent mistakes in specification.
[0037]
As described above, when a specific FAX server and communication terminal are specified by the partner specifying operation by operating the touch panel of the display 3a, the FAX 20 first determines the FAX in accordance with the registration contents of the registration management memory 7 shown in FIG. A call is made to the server partner number (03-1234-5678 in FIG. 4), and as described above, the terminal address of the communication terminal of the transmission partner is embedded in the TSI or DTMF signal and transmitted together with the data. On the FAX server side, the received data is transferred to the communication terminal having the received terminal address.
[0038]
In the registration contents of the registration management memory 7 shown in FIG. 4, the terminal addresses 997, 998, and 999 do not correspond to actual communication terminals, but correspond to a set of a plurality of terminal addresses. Accordingly, when a broadcast group is designated on the screen 2 shown in FIG. 5, the FAX 20 transmits all of the plurality of terminal addresses included in the broadcast group to the destination FAX server together with data to be transmitted. To do. Then, the FAX server sequentially transfers the received data to all the communication terminals corresponding to the received plurality of terminal addresses.
[0039]
As a result, a plurality of communication terminals on the LAN 30 can be associated with a specific destination designation operation. Therefore, for each communication terminal, a destination designation operation as shown in FIG. Since there is no need to perform the designation operation, the partner designation operation required for designating a plurality of communication terminals on the LAN 30 can be simplified.
[0040]
Next, transmission processing in consideration of the difference in data format that can be handled by the communication terminal on the LAN 30 when data is transmitted from the FAX 20 to the communication terminal on the LAN 30 will be described with reference to FIG.
[0041]
In the figure, first, a communication terminal on the LAN 30 is designated by the operator by an operation as shown in FIG. 5 (process 101). Then, a data mode as to whether the data to be transmitted is FAX data or text data is selected by the operation of the operation unit 4 of the operator (process 102). As a selection method, when facsimile data is set as a default data mode and the data mode is set to text data, a selection menu is displayed on the display 3a of the display unit 3 in response to pressing of the function key 4f of the operation unit 4. Then, from the selection menu, the data mode can be set to text data by the touch panel.
[0042]
Then, the selected data mode is determined (determination 103). If the data mode is FAX data, the registered management memory 7 registers whether the partner communication terminal specified in processing 101 is FAX. 4 is judged by referring to the list as shown in FIG. 4 (decision 104), and if it is FAX (Yes in decision 104), the data to be transmitted matches the data format supported by the partner communication terminal. Since normal data transmission is possible, FAX communication is executed (process 105). If the data is not FAX data (No in decision 104), the data to be transmitted does not match the data format supported by the partner communication terminal, and normal data transmission is impossible. ). As a result, when normal data transmission is impossible, useless communication is not performed, and FAX communication is executed only when normal data transmission is possible. If communication is stopped in process 108, a transmission impossible report is output (process 109). As a result, the operator can immediately know that there is an error in his transmission operation. As an output form of this communication impossibility report, it is conceivable that the plotter 2 records and outputs the image described to that effect on a recording paper or displays it on the display 3 a of the display unit 3.
[0043]
If the data mode determined in the determination 103 is text data, a list as shown in FIG. 4 registered in the registration management memory 7 indicating whether the partner communication terminal specified in the process 101 is a PC is displayed. If it is determined by reference (determination 106), if it is a PC (determination 106: Yes), the data to be transmitted matches the data format supported by the partner communication terminal, and normal data transmission is possible. Therefore, data communication is executed (process 107). If the data is not text data (No in decision 106), the data to be transmitted and the data format supported by the partner communication terminal do not match and normal data transmission is impossible, so communication is stopped (process 108). ). Thereby, when normal data transmission is impossible, wasteful communication is not performed, and data communication is performed only when normal data transmission is possible. If communication is stopped in process 108, a transmission impossible report is output (process 109).
[0044]
As a result, even when a plurality of communication terminals having different data formats that can be supported are present on the LAN 30, data in the correct data format can be transmitted from the FAX 20 to the communication terminals on the LAN 30.
[0045]
In the above description, the terminal information of the communication terminal on the LAN 30 as shown in FIG. 4 and the terminal information such as the terminal name, terminal type, and data format registered in the registration management memory 7 in the FAX 20 are displayed on the FAX 20 side. Although originally input from the operation unit 4, the FAX server 31 originally manages the terminal address and terminal information of the communication terminal on the LAN 30 in order to transfer the data received from the FAX 20 to the communication terminal on the LAN 30. Accordingly, the correspondence list of the terminal address and the terminal information possessed by the FAX server is notified to the FAX 20, and the correspondence list of the notified terminal address and the terminal information is registered in the registration management memory 7 on the FAX 20 side. By doing so, it is possible to save the trouble of inputting the correspondence list from the operation unit 4.
[0046]
FIG. 7 shows a communication procedure between the FAX 20 and the FAX server 31 for that purpose. In the figure, the FAX 20 transmits a calling tone CNG to the FAX server 31, and in response thereto, the FAX server 31 transmits a called station identification signal CED to the FAX 20, and the standard capability and non-standard capability of the own apparatus. Is notified to FAX 20 by DIS / NSF. The FAX 20 notifies the full capability of its own device by the digital transmission command DTC and transfers the transmission right to the FAX server 31. The FAX 20 notifies that the communication is for requesting terminal information when notifying the full capability of the own device.
[0047]
Upon receiving the notification of the DTC, the FAX server 31 sets the standard capability within the range of DIS and DTC, sets the non-standard capability within the range of NSF and NSC, and notifies the FAX 20 by DCS / NSS. Send training check TCF. The FAX 20 receives the TCF and adjusts the transmission speed of the modem 9. When the adjustment is completed, the FAX 20 sends a reception preparation confirmation CFR to the FAX server 31.
[0048]
When the FAX server 31 receives the CFR, it transmits the terminal information data of the communication terminal on the LAN 30 instead of the FAX data, and the FAX 20 receives it. The FAX 20 stores and registers the received terminal information in the registration management memory 7, and thereafter designates the communication terminal of the transmission destination according to the procedure shown in FIG. 5 based on the stored terminal information. Can do.
[0049]
Further, since communication terminals on the LAN 30 are moved / changed relatively frequently, the correspondence between the terminal address of the communication terminal on the LAN 30 and the terminal information obtained by the FAX 20 by the procedure shown in FIG. There is a risk that correct data communication cannot be performed. The procedure shown in FIG. 7 is sometimes started by the operator of the FAX 20 to update the registered contents of the registration management memory 7, but this is troublesome for the operator.
[0050]
Therefore, when the FAX 20 includes the FAX server 31 in the terminal registered in the one-touch dial, the communication procedure shown in FIG. 7 is executed by calling the FAX server periodically (for example, every other week). The registration contents of the registration management memory 7 are regularly updated so that the correspondence between the correct terminal address and the terminal information can always be maintained.
[0051]
In the above-described embodiment, the communication terminal device and the communication server device according to the present invention have been described using the FAX and FAX server capable of handling FAX data and text data as examples. However, the present invention is not limited thereto. The present invention can be applied to communication terminal devices and communication server devices compatible with various data formats.
[0052]
