Description

How to opt out from the fax

The present invention relates to a facsimile, and more particularly, to a method of receiving a facsimile message by selecting a sending facsimile at a receiving side.

The general public now lives in a flood of information, and facsimile has become commonplace as a device for information delivery. However, while various types of information can be conveniently delivered by transmitting or receiving images using a facsimile, unnecessary messages such as advertisement flyers are frequently received regardless of the receiver's intention. As a result, not only wasting waste of recording paper unnecessarily at the receiver side, but even when there was a facsimile message to be urgently received, it was frequently interrupted by receiving unnecessary advertisement flyers.

Accordingly, techniques have been devised to prevent reception from unwanted places. As such a technique, there has been a method of receiving a fax message by selecting a sending fax machine at a receiving side using a password. It sets and sets an acceptable password in the receiving fax machine and notifies only the sender who wants it. Then, when the sending fax performs the protocol with the receiving fax to send the message, the receiving fax receives the fax message only after the password is entered in front of the called subscriber identification (CSI). Therefore, the sender who did not know the password set in the receiving fax could not send the fax message, so the receiver could receive the fax message only from where he wanted. The CSI includes its own identification, that is, the calling party's country code, area code, subscriber number, etc., transmitted to the receiving facsimile when the sending facsimile performs the protocol with the receiving facsimile. .

However, as described above, in the method of selecting a transmission facsimile on the receiver side using a password, the transmitting party must notify the sending party of the password of its own facsimile, and the transmitting side must also input the password into the CSI. In addition, since this method cannot receive a facsimile message from a transmitting party who does not know a password, it cannot receive a facsimile message even if it is necessary to receive a facsimile message from an unspecified number.

As described above, there is a problem in that it is not possible to prevent the reception of unnecessary facsimile messages at all, or even when receiving a facsimile message by selecting a sending facsimile using a password, the password has to be notified and the sender has to enter it. In addition, there was a problem that does not receive even the required facsimile message.

It is therefore an object of the present invention to provide a method which can refuse to receive facsimile messages from undesired locations.

The present invention for achieving the above object is to receive a facsimile message when the facsimile call is received with the facsimile is set to receive the facsimile message, the CSI received from the sending facsimile to match the facsimile set to receive the facsimile message It is characterized by rejecting. The reception rejection is set by storing CSI input by a user in a random access memory (RAM).

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

First, a configuration and operation of a facsimile useful for understanding the present invention will be described with reference to FIG. 1, which shows a block diagram of a conventional facsimile. The controller 100 includes a microprocessor and controls the operation of the facsimile according to a program stored in a read only memory (ROM) 112. The operating panel (OPE) 102 has a plurality of numeric keys, function keys and a display device, and applies key data according to key input to the control unit 100 and controls various types of facsimile under the control of the control unit 100. Display the status. The real time clock (RTC) 104 provides the current time data to the controller 100. The sensor unit 106 detects the state of each part of the facsimile, including the remaining amount of the recording paper, the original, and the like, and provides it to the controller 100. The recording unit 108 prints and outputs an image copied or received under the control of the control unit 100. The scanning unit 110 scans an original and outputs image data corresponding to the original image to the control unit 100. The ROM 112 stores an operation program, a protocol control program, and various reference data of the controller 100. The RAM 114 temporarily stores data according to program execution of the controller 100. The modem (modulator-demodulator) 116 modulates the output data and the image data of the control unit 100 into an analog signal and transmits the signal to the other party's facsimile through the line interface unit (LIU) 118 and transmits the LIU 118 to the counterpart. The demodulated analog signal is applied to the controller 100 by demodulation. The LIU 118 forms a line between the modem 116 and the telephone line under the control of the controller 100.

Communication for the document transmission between the facsimile as described above is performed by performing a protocol according to a transmission control procedure promised in advance. An example of such a transmission control procedure is shown as FIG. 2 illustrates a typical example of transmitting and receiving a facsimile message by performing a protocol according to a transmission control procedure between the transmission facsimile 200 and the reception facsimile 202 configured as shown in FIG. At this time, the control unit 100 of the receiving facsimile 202 performs a receiving operation according to the processing flowchart shown in FIG.

Referring to FIGS. 1 to 3, a conventional reception operation in which a reception fax 202 receives a fax message by performing a protocol according to a transmission control procedure when a call starts from the transmission fax 200 will be described. In the following description, it is assumed that the fax of FIG. 1 is a receiving fax. First, when a ring signal according to a call is received from the transmission facsimile 200 through a telephone line, the LIU 118 detects and notifies the control unit 100. In response to this in step 300 of FIG. 3, the controller 100 controls the LIU 118 in step 302 to connect the modem 116 to the telephone line.

In this state, the transmit and receive faxes 200 and 202 transmit and receive Calling Tone (CNG) and Called Station Identification (CED) to set up a call, and then use DIS (Digital identification signal), DCS (Digital command signal), CSI, Send and receive training data and confirmation to receive (CFR) sequentially to verify and set up mutual capabilities. Next, the transmit and receive faxes 200 and 202 transmit and receive image data which are actual facsimile messages. After completing the transmission of the facsimile message, the send and receive facsimile (200, 202) between the end of the procedure (EOP) and the message confirmation (MCF) to send and receive, the sending facsimile 200 receives the DCN (Disconnect) to the receiving facsimile (202) Upon transmission, the receiving facsimile 202 controls the LIU 118 to disconnect and terminate the line connection.

Accordingly, the control unit 100 of the receiving facsimile 202 receives the CNG after performing the step 302, and then controls the modem 116 in step 304 according to the transmission control procedure. DIS is sequentially transmitted to the transmission facsimile 200, and in step 306, DCS and CSI are sequentially received. The control unit 100 receives the training data in step 308 and transmits the CFR in step 310 in response thereto, and receives the image data of the facsimile message in step 312 and then EOP in step 314. When receiving the MCF is transmitted in step 316, and receives the DCN in step 318 to control the LIU (118) in step 320 to terminate the line connection to terminate the reception and the standby state.

As described above, during the execution of the protocol in the facsimile, the transmission facsimile 200 transmits its own ID, the CSI, and the contents of the CSI are recorded at the front end of the receiving recording sheet. The present invention uses these CSIs to identify faxes that are not intended to be received and rejects receiving fax messages.

4 is a flowchart illustrating a receiving process of a fax according to an embodiment of the present invention. The operation according to the flowchart of FIG. 4 is programmed in the ROM 112 to be performed by the controller 100. The user then sets a bouncing for the facsimile that does not wish to receive the facsimile message. The bouncing is set by storing the CSI of the facsimile to be received by the user in the program mode of a normal facsimile in the RAM 114. do. In this case, the CSI input for setting the reception rejection is the content recorded at the front end of the reception recording sheet such as the advertisement flyer, which is previously received, and is input by the user in advance through the operation unit 102.

In this state, when a ring signal is received according to the facsimile call, the controller 100 controls the LIU 118 in step 402 in response to step 400 of FIG. 4 to connect the modem line 116 to the telephone line. do. After that, the control unit 100 receives the CNG and transmits the CED and the DIS to the transmission facsimile 200 by controlling the modem 116 in step 404 according to the transmission control procedure of FIG. 2 as described above. In step 406, DCS and CSI are sequentially received.

At this time, the control unit 100 compares the CSI received from the transmission facsimile 200 with the CSI stored in the RAM 114 in step 408 to check whether there is a match. In this case, if the received CSI is different from the CSI which is set as the reception rejection, the control unit 100 performs the same operation as that in the steps 308 to 320 of FIG. 3 described above in steps 410 to 422 to receive the facsimile message. Receive and go to standby. On the contrary, if the CSI received in step 408 matches the CSI set in the reception rejection, the control unit 100 transmits the DCN to the transmission facsimile 200 in step 424 without further proceeding with the reception procedure. In step 422, the line connection is disconnected and placed in a standby state.

Therefore, the recipient can selectively refuse to receive fax messages only where they do not want them. Accordingly, there is no hassle of notifying the sender of the password in advance, as well as receiving only the necessary facsimile messages and preventing the reception of unwanted facsimile messages.

As described above, the present invention has the advantage that the receiver can easily and freely reject the facsimile reception from the unwanted place.
