Abstract

PURPOSE:To improve the communication efficiency by interrupting present communication and initiating new communication when an incoming call is detected from an urgent communication destination during the communication. CONSTITUTION:When a communication control section 6 detects an incoming call from an opposite party, the control section 6 receives a dial number of a caller station included in incoming information during the communication, retrieves an urgent incoming destination address table registered in a terminal equipment, and instructs a busy reply to the incoming call when no dial number exists, and issues a instruction to interrupt the preset communication tentatively when the dial number exists, and the communication to the urgent incoming call is instructed to the communication control section 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device having an emergency communication means.

[Prior Art] Conventionally, a facsimile machine is connected to a telephone line, etc.
When an incoming call is answered, the communication process is executed,
When all communications are completed, the device is configured to return to a standby state for the next incoming call.

Further, in recent years, ISDN networks have begun to spread, and facsimile machines compatible with this network have been required.

[Problems to be Solved by the Invention] However, in the above conventional example, when the facsimile device is in communication, even if there is an urgent call request from another terminal, which is a third party, the facsimile device is unable to receive the call because it is already in communication. , a signal indicating a busy state is returned to other terminals, causing problems such as emergency communications going into a waiting state (redial) or ending without being executed.

The present invention was made to solve the above problems, and
It is an object of the present invention to provide a facsimile device capable of interrupting the current communication and starting a new communication when an incoming call from an emergency communication partner is detected during communication.

[Means for Solving the Problems] In order to solve the above problems, a facsimile apparatus of the present invention has the following configuration. That is, in a facsimile machine connected to an ISDN network, there is a monitoring means that monitors new incoming calls during communication, and when the monitoring means detects an incoming call, the destination address information included in the incoming call information is changed to the emergency destination. and a communication means for interrupting the current communication and starting a new communication if the judgment result of the judgment means is that the destination is an emergency destination.

[Operation] In the above configuration, a new incoming call is monitored during communication, and when an incoming call is detected, it is determined whether the destination address information included in the incoming call information is an emergency destination.

If the determination result is that the destination is an emergency destination, the current communication is interrupted and a new communication is started.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Description of Configuration (Fig. 1)> Fig. 1 is a schematic block diagram showing the configuration of a facsimile apparatus in an embodiment. In the figure, 1 is a control oil section that controls the entire operation of this device, including the CPU, ROM,
It is composed of RAM, etc. Reference numeral 2 denotes an operation display section, which controls the manual operation of keys and the LCD display. Reference numeral 3 denotes an image manual section (scanner) that reads the transmitted original. 4 is an image output unit (printer) that decodes the received image information to form a visible image. 5 is an image storage unit that stores encoded image information. Reference numeral 6 denotes a communication control unit, which uses a D channel (Dch) system (Dch) system (which performs data communication with the circuit unit) which performs call side i distribution according to the communication procedure of ISDN.
Bah) consists of a control section.

7 is a control bus for the control section 1 to control each unit; 8 is a video bus for handling image data; and 9 is an ISDN line.

Description of Processing Procedure (FIG. 2)> Next, the processing procedure of the control unit 1 in this embodiment will be explained below according to the flowchart shown in FIG. Furthermore, the second
The processing procedure shown in the figure is stored in the ROM of the control unit and is executed by the CPU. Further, normal transmission processing and the like are well-known techniques and will not be described here.

First, in step S1, the communication control section 6 monitors whether or not an incoming call has been detected from the other party, and when the communication control section 6 manually inputs a detection signal, the process proceeds to step S2.

In this step S2, it is determined whether or not communication is currently being carried out, and if communication is not being carried out yet, step S4
The process proceeds to , and the communication control unit 6 is instructed to start the reception process according to the communication procedure. However, if communication is already in progress, the process advances to step S3, and the dial number of the calling station included in the @ communication information is input from the communication control i-time section 6. Next, the process proceeds to step S5, and the emergency destination address table registered in the terminal is searched from the input dial number. When the search is completed, the result is determined in step S6, and if the search does not exist, the process proceeds to step S8, instructs to make a busy response to the incoming call, and returns the process to step S6. However, if they match, the process advances to step S7, and the communication system wholesaler 6 is instructed to temporarily interrupt the communication that is already in progress, and then it is confirmed that the communication has been interrupted. , the process proceeds to step S9, and instructs the communication control unit 6 to perform communication operations in response to the emergency call.

As explained above, according to this embodiment, a facsimile device connected to an ISDN network monitors new incoming calls even during communication, and the incoming call at this time is an emergency call registered in advance in the terminal. If the address matches the destination address, it is possible to interrupt the current communication, give priority to communication with the emergency communication destination, and secure the emergency communication.

Additionally, by placing a parameter on the Dch protocol that indicates whether the call is an emergency communication call, the receiving side can use that parameter to control whether or not to perform a new communication with priority over the existing communication. Other methods are also possible.

Furthermore, if the address matches the address of the other party for emergency communication, a method may be considered in which, instead of immediately interrupting the current communication, a warning is given to the operator (sound or display) and the emergency communication is executed by the operator's operation.

[Effects of the Invention] As explained above, according to the present invention, when an incoming call from an emergency communication destination is detected during communication, communication efficiency is improved by interrupting the current communication and starting a new communication. It has the effect of
