Description

How to check the calling party number and incoming time for incoming message in fax equipped with answering machine

The present invention relates to facsimile, and in particular to an additional service method.

In general, when a document is transmitted between a sender and a receiver, the sender fax transmits additional information related to the transmission time, transmission page, etc. together with the CSI (Called Subscriber Identification) before transmitting the image data of the original. The CSI includes its own identification transmitted by the sending side facsimile to the receiving side facsimile, that is, the calling party's country code, area code, subscriber number, and the like. Therefore, CSI is typically the telephone number of the sending fax. The transmission time is the time when the corresponding page is transmitted from the sending side facsimile, and includes the year, month, day, hour, and minute. The sending page is a serial number given from the first page of the original to be sent. The receiving side facsimile printed the CSI, the transmission time, and the transmission page received from the sending side facsimile at the leading edge of the recording sheet for each page.

On the other hand, a facsimile equipped with an answering machine is currently used. Such a facsimile, like a typical answering machine, sends an announcement message to a caller when an incoming call is received and records an incoming message coming from the caller. When the incoming message recorded later was reproduced by the user, it was difficult to know the calling party number (Caller ID: CID) or the incoming time.

As described above, the facsimile could be confirmed by the user by printing the CSI or transmission time additionally received from the sending side facsimile on the recording sheet when receiving the original, but when the incoming message is recorded according to a general telephone call It did not have a function of notifying the user of the telephone number, namely CID or incoming time. As a result, the incoming message could not be confirmed by the user.

As described above, conventionally, there is an inconvenience in that the CID and the incoming time cannot be confirmed for the incoming message according to the general incoming call.

Accordingly, an object of the present invention is to provide a CID verification method capable of confirming a CID for a recorded incoming message.

Another object of the present invention to provide an incoming time confirmation method that can confirm the incoming time for the recorded incoming message.

2 is a process flow diagram according to an embodiment of the present invention.

The present invention for achieving the above object is to detect the CID by the CID detection device every time there is an incoming call from the CO (Central Office) and to check the incoming time to record the incoming message CID and incoming call in the incoming message It allocates and stores time information, and displays the CID and incoming call time assigned to the incoming message when the recorded incoming message is played.

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. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Currently, most local exchanges send additional CIDs to the called party via trunk line, so that the called user can check the calling party's phone number. Accordingly, private exchange systems, such as key phone systems and premises exchange systems, detect CIDs received from trunk lines by the CID detection apparatus and serve the subscribers.

As described above, the present invention enables the CID to check the incoming message by using the point of transmitting the CID to the called party by the CO line. The facsimile for carrying out the present invention further includes a CID detection device 120 in a facsimile equipped with a conventional answering machine 122, as shown in the block diagram of FIG. In FIG. 1, a central processing unit (CPU) 100 controls an operation of a 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 central processing unit 100 and controls the central processing unit 100. Displays various states of the facsimile. In this case, a display device typically employs a liquid crystal display (LCD). Real time clock (RTC) 104 provides the current time data to the central processing unit (100). The sensor unit 106 detects the state of each part of the facsimile, including sensing the remaining amount of the recording paper, document detection, and the like, and provides the same to the CPU 100. The recording unit 108 prints and outputs an image copied or received under the control of the central processing unit 100. The scanning unit 110 scans an original and outputs image data according to the original image to the central processing unit 100. The ROM 112 stores an operation program, a protocol control program, and various reference data of the central processing unit 100. The random access memory (RAM) 114 temporarily stores data according to program execution of the CPU 100. Modem (modulator-demodulator) 116 modulates the output data and the image data of the central processing unit 100 into an analog signal and transmits it to the other party's facsimile through the line interface unit (LIU) 118 and LIU from the trunk line. The analog signal received through 118 is demodulated and applied to the CPU 100. The LIU 118 is connected to a trunk line of a telephone network such as a public switched telephone network (PSTN) and forms a line between the modem 116 and the trunk line under the control of the central processing unit 100. The LIU 118 detects when a ring signal is received from the trunk line and informs the CPU 100. The CID detection device 120 is connected to the trunk line through the LIU 118 and detects the CID received from the trunk line to notify the central processing unit 100. The answering machine 122 is connected to the trunk line through the LIU 118 and is controlled by the central processing unit 100 to send a guide message to the trunk line, to record the incoming message received from the trunk line, and to reproduce and output the recorded incoming message. .

Figure 2 shows a process flow diagram according to an embodiment of the present invention in the facsimile as described above. The operation according to the flowchart of FIG. 2 is performed by the central processing unit 100 of FIG. 1 and programmed in the ROM 112. First, when the facsimile receives a ring signal from the trunk line to the LIU 118 in the standby state, the LIU 118 detects the ring signal and notifies the central processing unit 100 that there is an incoming call. At this time, the CID is received from the trunk line at every rest period of the ring signal, and the received CID is detected by the CID detecting apparatus 120. Then, the central processing unit 100 detects the CID through the CID detection device 120 in step 204 in response to the ring detection in step 200 and confirms the incoming time, that is, the current time, by the RTC 104. The CID and the incoming time information are stored in the RAM 114. At this time, the incoming time information stored is year, month, day, hour, and minute information for the corresponding incoming call. Thereafter, the central processing unit 100 checks whether or not recording is performed in response to receiving an incoming message from the caller in step 206. If the incoming message is recorded by the answering machine 122, the central processing unit 100 allocates the CID and the incoming time information stored in the step 204 to the corresponding incoming message in step 208. Return to the main routine. Otherwise, if the incoming message is not recorded by the answering machine 122, the central processing unit 100 returns to the main routine as it is in step (206). Therefore, whenever the incoming message is recorded according to the incoming call, the CID and the incoming time information of the incoming message are stored in the RAM 114.

In the above state, if the user inputs a playback key on the operation panel 102 to reproduce the incoming message, the central processing unit 100 responds to the operations 210 through 212 in steps 200 through 202. Follow the steps. In steps 210 to 212, the central processing unit 100 reads the CID and incoming call start information assigned to the incoming message to be reproduced from the RAM 114 and displays it through the display device on the operation panel 102 and the answering machine. A replay operation is performed on the 122 to reproduce the incoming message.

Therefore, the user can easily check the CID and the incoming time when the call was received for the recorded incoming message.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. In particular, in the embodiment of the present invention has shown an example of confirming the CID and the incoming time together, it may be to check only one of the CID or the incoming time as needed. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.

As described above, the present invention has the advantage that the user can easily check the CID and the incoming time even for the incoming message according to the general incoming call.
