Abstract

PURPOSE:To prevent trouble and a problem caused by rejection of an incoming call when an incoming call request is received in the state of incoming call disable by sending a message representing the state of enable incoming call to a caller station rejecting the arrival of a call based on information stored in a storage means. CONSTITUTION:Whether or not the arrival of a call is possible is discriminated and when the arrival of the call is possible, a message data is sent to a call number stored at the n-th arrival of call (S91, 92). The message data is a picture data resulting from a character code expanded in a bit pattern and stored in a RAM and the compression code read by a communication control section is coded and the result is sent. Then whether or not the transmission of a message data is finished as to all stored call numbers is discriminated (S94), and when the transmission is not finished, the button is advanced by one and the processing is proceeded to a succeeding call number (S94'). When it is discriminated that all the transmission is finished by the discrimination in the S94, the step proceeds to the S95, the stored call number is cleared and this operation is finished.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device, and more particularly to a communication device for rejecting an incoming call request from a network.

[0002]

2. Description of the Related Art In recent years, facsimile machines have rapidly penetrated into companies and have established themselves as office automation equipment essential for business.

Among facsimile machines, high-end machines having a hard disk and a large-capacity DRAM as an image memory are known, and this kind of machine is used as a center facsimile or the like and cannot receive an incoming call due to a paper cut or a paper jam. In this case as well, the substitute reception function of the image memory allows incoming calls until the image memory overflows.

However, it is very difficult to mount such a hard disk or an image memory having a large capacity DRAM in a popular type facsimile.

[0005]

On the other hand, in the popular type facsimile machine which occupies most of the facsimile machines, the capacity of the image memory for accumulating image data is small, and when the image cannot be received due to, for example, recording paper shortage or paper jam, an incoming call is received. There are many cases in which an error ends simply by rejecting.

At this time, the operator on the calling side who is rejected the incoming call informs the operator on the receiving side of the abnormality of the facsimile on the receiving side by telephone or the like, and if the operator on the calling side responds to this, communication can be performed. Become so.

However, if the operator on the receiving side is absent, the operator on the calling side cannot do anything, and it may be known when the facsimile on the receiving side can receive the call. In some cases, after that, I forget to send the document,
This kind of case is a very big problem because it may cause a big obstacle to the business.

The above problems are not limited to facsimile machines, but are common to communication machines that may reject incoming calls.

An object of the present invention is to solve the above problems and prevent various troubles and problems caused by rejecting an incoming call when an incoming call request is received in a state where the incoming call is not possible.

[0010]

In order to solve the above problems, according to the present invention, when a call rejection is made in a communication device which rejects the call request from the network, information regarding the call rejection is given. Has a means of storing
When the incoming call is possible after the incoming call is rejected, a message indicating that the incoming call is ready is sent to the originating station that rejected the incoming call based on the information stored in the storage means.

[0011]

According to the above construction, when the incoming call is rejected, after the recovery from the incommunicable state, the incoming call can be accepted to the calling station which rejected the incoming call based on the information stored in the storage means. You can send a message to the effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 shows the structure of a communication device adopting the present invention.

In the figure, reference numeral 11 is a control unit CP
It is a microcomputer circuit composed of U, ROM, RAM, clock IC, other I / O, etc. The software control of the microcomputer controls the operation of the entire device and manages various data.

Reference numeral 12 denotes an operation unit, which receives an operator's key input including various keys and a display unit and displays various information. Reference numeral 13 is an image reading unit, which includes a CCD, an A / D converter, an image processing device, and the like, and photoelectrically converts the optically read data into A / D.
Image processing such as conversion, image correction, and binarization is performed.

Reference numeral 14 is a recording unit, which is composed of an output device such as a thermal printer, a thermal transfer printer, a laser beam printer, etc., and receives image data, image data read by a reading unit (at the time of copying an original), or a control unit. The formed image data is output.

Reference numeral 15 is a communication control unit, which is a compression code encoding / decoding processing device, a line interface circuit,
Or consists of a telephone circuit, which sends and receives image data,
Control incoming and outgoing calls. In this embodiment, the line is I
Assuming SDN, the communication control unit 15 can be a line interface for ISDN.

Next, the operation of the above configuration will be described.

First, the communication control procedure of FIGS. 2 and 3 will be described. The illustrated example assumes a call setup and call teardown procedure using the D channel of ISDN.

In FIG. 2, the called side is set up from the network.
If the (call setting) message is received and the incoming call is possible, the incoming call state is established after the ALERTING and connection / confirmation messages are exchanged, and the data transfer phase is passed to proceed to the call dissolution procedure.

However, when the incoming call cannot be accepted, the incoming call is rejected when the SETUP message is received as shown in FIG. 3. Therefore, by rejecting the incoming call by sending a disconnection message, the call is disbanded.

SETUP (call setup) sent to the called side
The message has the contents shown in FIG. The call number information in FIG. 4 is the so-called telephone number of the other party.

FIG. 5 shows a call origination call storage control flow of the present invention. In steps S1 to S2 to S3, a call signal is received, overlap information is transmitted, and SET is performed in accordance with a call setting procedure.
It operates with UP message reception.

Next, in step S4, it is determined whether or not the terminal can receive an incoming call. The criterion is determined by, for example, the memory overflow, the absence of paper in the recording unit 14, the detection of paper jam, and the like performed by the control unit 11. If the incoming call is possible, the process proceeds to the connection procedure as shown in FIG.

On the other hand, if the incoming call cannot be accepted and the incoming call is rejected, the call number in the setup message shown in FIG. 4 is stored in the RAM area of the control unit 11 in step S5.

Then, in steps S6, S7 and S8, the disconnection message is transmitted, the release message is received, and the release completion message is transmitted to reject the incoming call.

As described above, when rejecting an incoming call,
The call number and the arrival time of the other party are sequentially stored in the RAM area of the control unit 11. The arrival time is the clock I of the control unit 11 in FIG.
You can know by C. FIG. 6 shows how stored call numbers and messages are stored. The lower half of FIG. 6 is an area for storing messages and image bit patterns used for control described later.

Next, how to use the information such as the call number and the arrival time of the other party stored in the incoming call rejection will be described in three cases.

1) First, with reference to the flow chart of FIG. 7, an example of control for displaying the call number received when the call is rejected, control for selecting the call number, and control for calling the selected call number will be described.

In the figure, step S71 is for determining whether or not the key number display command key input, which is one of the operation keys 12 in FIG. 1, is input. If this key is input, step S71 is executed.
72, the call number is displayed on the display unit of the 12 operation units. Sensing of key input and display control are known techniques, and detailed description thereof will be omitted. In step S73, the input of the calling command key, which is one of the keys in the operation unit 12, is determined. If there is a calling command, the procedure proceeds to calling the call number displayed in step S74. move on.

If the input is not a call command key, for example, if it is a numeric input key, the process proceeds to steps S75 and S76 to display the call number corresponding to the entered numeric key.

In this case, it is also possible to select the call number with a scroll key, for example. In step S77, the end of this operation is waited for by inputting the stop key.
When the call number clear key waiting for the call number clear key is pressed in step S78, the call number is cleared in step S79.

In this way, the information such as the call number and the arrival time of the other party stored in the call rejection can be displayed,
The user can know the partner station with which communication is attempted during the period when communication is impossible. In addition, the user can select a desired partner station from the partner stations that rejected the call, and call the partner station for telephone contact or facsimile communication. Easy to do.

2) Next, an example of control for printing out the call number, the arrival time, and the message received when the call is rejected will be described with reference to the flowchart of FIG.

In step S81, the stored message,
The call number and the arrival time are expanded into a bit pattern and stored in the RAM. The expansion to the bit pattern is R of the control unit 11.
It is realized by reading the bit pattern stored in the OM for each code. Alternatively, a character generator ROM may be used.

Step S82 has the end of step S81. In step S83, the developed bit pattern is output to the recording unit 14, and since this control is a known technique, detailed control is omitted.

FIG. 9 shows an example of the output image data. According to this configuration, not only the display but also the information such as the call number and the arrival time of the other party stored in the call rejection can be obtained as a hard copy. The user can keep a record of the information about the partner station with which he / she tried to communicate while the communication was impossible.

3) Using the flow chart of FIG. 10, after recovering from the state where the call cannot be received, using the call number of the other party stored in the call rejection, message data for notifying the other station of recovery, for example, in FIG. The message “Incoming call is now available. We apologize for the inconvenience. ○ × Company 03-33X3-4X
A control example of transmitting image data such as "1X" will be described.

In step S91, it is determined whether an incoming call is possible. If yes, the process proceeds to the next step. Step S
At 92, message data is transmitted to the call number stored in the nth position.

The message data is image data in which the character code is expanded into a bit pattern and stored in the RAM in the same manner as the above-mentioned 2, and the compressed code read by the communication control unit 15 is encoded and transmitted.

In step S93, it is determined whether or not the transmission of the message data has been completed for all the stored call numbers. If not, in step S93 the pointer is advanced by 1 and the message is transmitted to the next call number. Go to.

If it is determined in step S93 that all transmissions have been completed, the process proceeds to step S95, the stored call number is cleared, and this operation ends. However, the call number may be cleared each time transmission of message information for one call number is completed.

In this way, after recovery from the call-disabled state,
By using the call number of the other party stored in the call rejection, you can send a message notifying the other station of the recovery,
You can apologize for being disrespectful and encourage the other station to respond.

According to the above embodiment, when the incoming communication is rejected in the state where the incoming call cannot be received due to, for example, no paper or paper jam, the incoming call side is stored by storing the call number of the outgoing call side. Information will remain as some kind of evidence, and the operator on the receiving side will be able to urge the other party to send by telephone, for example, by knowing the above-mentioned call number, and prevent communication troubles and business troubles due to unreceived calls. It becomes possible.

Further, by providing the means for selecting the stored call number and the means for automatically calling the selected call number, the labor of the operator can be saved.

Further, when the incoming call becomes possible, a message is automatically transmitted to the other party who rejected the incoming call, so that the communication stop state can be automatically notified to the partner station who rejected the incoming call without the operator's trouble. Therefore, business activities through facsimile can be carried out more smoothly.

Further, in the above-mentioned embodiment, since the call number of the calling side is automatically cleared after the recovery notification is given to the partner station which rejected the incoming call, no troublesome recovery operation is required. Further, it is possible to avoid the trouble caused by forgetting to erase such information.

In the above, the facsimile apparatus is assumed, but it goes without saying that the present invention can be implemented in other communication apparatuses such as a data terminal. For example, on a telephone, the recovery message could be sent as a voice message.

In the above, ISDN is assumed as the network, but a similar configuration can be implemented in a communication device using a telephone network. For example, in a G3 facsimile machine, T
Since the telephone number of the calling station can be notified to the receiving side by using the SI signal or the like, this information can be stored and used.

[0050]

As is apparent from the above, according to the present invention, in a communication device that rejects an incoming call in response to an incoming call request from the network, when the incoming call is rejected, a means for storing information about the incoming call rejection is provided. If the incoming call is possible after the incoming call is rejected, a message indicating that the incoming call is ready is sent to the originating station that rejected the incoming call based on the information stored in the storage means. Therefore, when the incoming call is rejected, after the recovery from the incommunicable state, the recovery can be notified to the calling station that rejected the incoming call based on the information stored in the storage means, and the incoming call request can be made when the incoming call is impossible. It is possible to provide an excellent communication device capable of preventing various troubles and problems caused by rejecting an incoming call when receiving a call.
