Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication terminal device that performs facsimile communication via an integrated service digital network.

[Prior Art] Conventionally, in a communication terminal device connected to an integrated service digital network (hereinafter referred to as 15DN), when displaying the status of the other party's terminal on a display, the other party's status is displayed based on the operation of the own terminal. Either the status of the terminal is estimated and displayed, or the status of the other party's terminal is estimated and displayed based on information in the data transfer procedure (protocol) during image data communication with the other party's terminal.

[Problems to be Solved by the Invention] However, in this way, the state of the other terminal is estimated and displayed based on the operation of the own terminal, or the state of the other terminal is estimated and displayed based on the information in the data transfer procedure during image data communication with the other terminal. If the status of the other party's terminal is estimated and displayed, it is not possible to display the status of the other party's terminal in detail and accurately. For example, if a device capable of memory reception is used as the other party's terminal, and even if the other party's terminal has no recording paper and memory reception is performed during facsimile communication from the own terminal, the own terminal simply assumes that the other party's terminal is receiving normally. I was only able to make judgments, and therefore I was only able to make certain displays.

Therefore, the present invention makes it possible to display the status of the communication partner in detail and accurately by using the bucket exchange mode, and also to notify the other party's status in detail and accurately by using the packet exchange mode. The present invention aims to provide a communication terminal device that can improve operator's work efficiency and improve services.

[Means for Solving the Problems] The present invention provides a communication terminal device that performs facsimile communication with a partner terminal in both circuit switching mode and packet switching mode via an integrated service digital network. A status information communication means that communicates various status information of its own terminal in packet exchange mode using a channel, an information display device, and an information display device that receives various status information sent from a partner terminal in packet exchange mode and displays the status information. This system is equipped with a display control means for displaying on the screen.

[Operation] In the present invention having such a configuration, various status information of the own terminal is communicated to the other terminal in a packet exchange mode using a channel different from the image communication channel. It also receives various status information sent from the other party's terminal in packet exchange mode and displays the status information on the information display.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a communication terminal device, where 1 is a terminal control unit equipped with a microprocessor, and 2 is a ROM (read-only ψ 3 is a RAM that stores various data such as one-touch dial number information
(Random access memory), 4 is a key input unit for inputting destination dialed numbers, etc., 5 is a keypad for displaying and informing the operator of information such as dialed numbers, messages, own terminal status, other party's terminal status, etc. An information display section, 6 a telephone control section for voice communication, 7 a facsimile control section for facsimile communication, and 8 a line control section serving as an interface for connection to the 15DN.

The terminal control unit 1, ROM 2, RA 13, key input unit 4, display unit 5, and each control unit 6, 7.8 are connected to a path line 9.
electrically connected via.

The facsimile control section 7 includes a reading control section 71 that optically reads a document, and a print control section 72 that prints out the document data sent from the 15DN and prints out the document data read by the reading control section 71. , an encoding/decoding control section 73 connected to the reading control section 71 and the printing control section 72 and encoding and decoding data;
It is comprised of a memory control section 74 that temporarily stores transmitted document information and received document information.

When performing facsimile communication using a communication terminal device with such a configuration as a calling terminal (own terminal) 11 and a called terminal (other party terminal) 12 as shown in Fig. 2, the circuit switching mode of the B channel of the 15DN is used. to communicate. Note that the calling terminal is D until facsimile communication is possible.
The channel is used to perform a call setup procedure for connecting a call with a called terminal. At this point, the B channel for facsimile communication is connected.

The calling terminal then establishes a packet communication link on the D channel to communicate status information with the called terminal.

When entering the facsimile communication state, the calling terminal and the called terminal each transition between operating states.

For example, as shown in FIG. 3, the calling terminal enters a document reading state in order to transmit a document. At this point, the calling terminal has transitioned from the idle state to the document reading state, so it transmits "reading display information" to the called terminal in packet exchange mode.

On the other hand, if the called terminal is performing memory reception, for example, it transmits "memory input display information" to the calling terminal in packet exchange mode.

Thereafter, when the calling terminal finishes reading the document and enters an idle state, it transmits "rEND display information" to the called terminal in the packet exchange mode.

In addition, when the called terminal finishes receiving data in its memory and prints out the contents received in its memory, it transmits "printed output display information" to the calling terminal in the packet exchange mode.

Furthermore, when the called terminal finishes printing and enters an idle state, it transmits "rEND display information" to the calling terminal in the packet exchange mode.

While communicating display information like this, the terminal control unit 1 of the calling terminal controls the information display unit 5 to display the left side 5a of the screen.
The operating information of the own terminal is displayed on the screen, and the operating status of the other terminal is displayed on the right side of the screen 5b.

First, at the time of transmitting the "reading display information", the document reading state of the own terminal is displayed as an illustration on the left side 5a of the screen of the display unit 5. Subsequently, when the "memory input display information" is received, the memory reception status of the other party's terminal is displayed as an illustration on the right side 5b of the screen. Therefore, the display state of the information display section 5 becomes as shown in FIG. 4(a).

In addition, at the time of transmitting "rEND display information", the idle state of the own terminal is displayed on the left side 5a of the screen of the display unit 5 as characters rENDJ. Subsequently, when the "print output display information" is received, the print output status of the other party's terminal is displayed as an illustration on the right side 5b of the screen. Therefore, the display state of the information display section 5 becomes as shown in FIG. 4(b).

Furthermore, when receiving "rEND display information" from the other party's terminal, the idle state of the other party's terminal is displayed on the right side of the screen 5b.
Displayed in characters. Therefore, the display state of the information display section 5 becomes as shown in FIG. 4(C).

In this embodiment with such a configuration, during facsimile communication, it is possible to confirm that the own terminal has changed from an idle state to a document reading state, that the other party's terminal is performing memory reception,
The information display 5 indicates that the own terminal has finished reading the document and entered the idle state, that the other party's terminal has finished memory reception and has entered the print output state, and that the other party's terminal has entered the idle state. Since the information is displayed accurately, the operator can know not only the status of his own terminal but also the status of the other party's terminal accurately and in detail. This fact is displayed on the other party's terminal as well as on the information display 5, so that the relationship between the own terminal and the other party's terminal is reversed or similarly displayed, so that the other party's terminal can also know the status of the own terminal accurately and in detail. .

Therefore, the operators who operate each terminal can accurately know the status of each other, so that they can perform work appropriately according to the status, and work efficiency can be improved. It is also possible to improve services for users.

It goes without saying that the display form of the status on the information display section is not limited to that of the embodiment described above.

Further, in the above embodiment, the D channel is used as the channel for communicating status information in the packet exchange mode, but the channel is not necessarily limited to this, and in some cases, another B channel that is not used for image communication may be used. .

[Effects of the Invention] As detailed above, according to the present invention, the status of the communication partner can be displayed in detail and accurately by using the packet exchange mode, and the status of the own terminal can also be displayed in the packet exchange mode. It is possible to provide a communication terminal device that can send detailed and accurate information to the other party's terminal by using the information, and can improve the operator's work efficiency and improve the service.
