Description

Method for selective transmitting response message in telephone}

The present invention relates to a method for selectively sending a response message of a telephone. Particularly, when a missed call is made and an automatic response is made, the telephone number of the telephone is adapted to respond to a separately recorded message when a predetermined telephone number and an incoming telephone number match. The present invention relates to a method for selectively sending response messages.

In general, an answering machine is operated in such a way that when a missed call is received, the same pre-recorded message is sent, and the caller to the message leaves a message.

6 is a block diagram of a telephone using a conventional caller ID.

As shown therein, a caller ID unit 21 for receiving a call including a caller ID from the trunk line and demodulating the caller ID; A CPU 22 which receives the demodulated signal from the caller ID unit 21 and controls the output of the character data of the caller ID; A key input unit 23 connected to the CPU 22 to allow a user to input a key; An LCD display unit 24 for displaying the telephone number, name and time of the caller ID processed by the CPU 22; The memory unit 25 stores the caller ID processed by the CPU 22.

FIG. 7 is a flowchart illustrating a phone number output method using the caller ID of FIG. 6.

As shown therein, receiving a call from outside (ST1); If the received call includes a caller ID, detecting a caller ID by identifying the caller ID in the telephone number identification unit (ST2); A step ST3 of displaying the detected caller number on the LCD display unit 32 is performed.

Thus, when the called party's phone receives an FSK modulated call from the calling party's phone, it retrieves whether the received call contains an FSK caller ID. Thus, if the caller ID is included, the caller ID unit 21 demodulates the caller ID and sends it to the CPU unit 22. Then, the CPU unit 22 interprets the phone number included in the demodulated caller ID and displays it on the LCD display unit 32. The CPU terminates the caller ID data transmission by processing the call and generating a ring to the speaker.

Here, the caller ID refers to data that meets the International Telegraph and Telephone Consultative Committee (CCITT) V.23 or BELL202 standard when the call is received from outside, before or between the first and second rings. This is an identifier used to identify and call the caller's name, phone number, and time of call.

However, the conventional telephone number output method using the caller ID could not output a response message.

In addition, in the case of using an answering machine, when the user goes out after recording a response message, the same message is always sent out, so there is a disadvantage in that a general message can only be recorded. In other words, if a call comes from a certain place while you are away, you do not know the caller even if you want to send a ready message. In addition, even if there were many families, there was a limit to sending only one message.

On the other hand, the operation of performing an automatic response using a DTMF (Dual Tone Multi Frequency) signal will be described.

Fig. 10 is a block diagram of a telephone using a DTMF signal to which the present invention is applied, and has the same configuration as a conventional answering machine.

As shown here, the microphone 31 converts the voice signal into an electrical signal; A microphone amplifier 32 for amplifying a minute electrical signal input from the microphone 31; The analog signal input through the microphone 31 or the telephone line is converted into a digital signal for processing by a DSP (Digital Signal Process) 38 or a digital signal stored in the memory 39 or 40 to an analog signal. A codec (Coder-Decoder) 33; A speaker amplifier 34 for amplifying the analog signal output from the codec 33 to a sufficient degree to drive a speaker; A speaker 35 for converting the electrical signal amplified by the speaker amplifier 34 into sound pressure so that a person can hear; A voice processing unit 36 connected to the codec 33 and serving as an interface to exchange a signal with a telephone line; A button unit 37 which is controlled by the CPU 44 and is responsible for inputting various functions and operations of the telephone; A DSP (38) coupled to the codec (33) for processing digital signals; A RAM 39 connected to the DSP 38 to store a digital signal when a user records a response message or a message; A ROM 40 connected to the RAM 39 and storing a voice announcement ring tone, etc .; An LCD display 41 connected to the ROM 40 and outputting data processed by the CPU 44 in a message form; A trunk line control unit 42 for turning on or off the trunk line under the control of the CPU 44; A ring processor 43 for receiving a trunk line ring and transmitting it to the CPU 44; It is composed of a CPU 44 which controls the automatic answering operation of the answering machine and its overall functions.

11 is a flowchart illustrating a case of recording a response message using a conventional DTMF signal.

As shown therein, steps ST81 and ST82 determine whether the answering machine is a response recording operation in the standby state of the answering machine; In response to the response recording operation, transmitting a guide message and entering a response message recording mode (ST83); When the stop button is pressed or a predetermined time elapses after the recording in the recording mode, the recording mode is stopped and the recorded message is transmitted to the speaker (ST84 to ST86).

12 is a flowchart showing a case of transmitting a specific message using a conventional DTMF signal.

As shown therein, steps (ST91) (ST92) for determining whether a call is received by a call to the answering machine in the standby state of the answering machine; (ST93) (ST94), when the ring is received, sending out a ring tone to the speaker (35) and determining whether the number of rings has reached a certain number of times to output an auto-answer message; Sending an auto-reply message to a telephone line when the number of rings reaches a certain number of times (ST95); After sending the auto-response message, the user enters the message recording mode to perform the recording of the message (ST96 to ST98).

The conventional operation of performing the auto answer function using DTMF in such an answering machine will be described in detail as follows.

First, the response message recording operation will be described.

In other words, if you press the answer recording button in the standby state, an answering machine with a voice prompt message sends a message about how to record the answering message to the speaker, and then enters the answering recording operation. The case immediately enters the response message recording operation.

In the response message recording operation, the response message recording operation is stopped by a stop button or a predetermined maximum response message recording time (for example, 15 seconds). When the response message recording operation is completed by this operation, the answering machine immediately replays the recorded response message contents through the speaker to confirm whether the user has properly completed the response message recording operation, and then returns to the standby state.

In this case, if the contents of the response message are unsatisfactorily recorded, the user may change the contents of the existing response message by performing the first response message recording operation again.

When the response message is recorded in this way, the automatic answering telephone will be described with reference to FIG. 12 showing the flow of the automatic response, which can perform the automatic answering function when the CO line is received.

That is, when the trunk line ring is received in the standby state, the answering machine rings the sound through the speaker and checks whether a predetermined number of rings, generally four rings, are received in succession. So, if it is within a predetermined number of times, only a ring tone sounds, and when a predetermined number of rings are received, the CO line is connected (off-hook) through the CO line control unit 42, an answer message is sent to the telephone line, and the service message recording mode is entered. .

At this time, the answering machine records the message and checks the periodic sound or VOX (Voice activation, 7-second silence check) when the call is terminated. (Hook on)

Thus, when the user wants to check the recorded message, the user can check the recorded message by the play button.

However, this conventional DTMF technology can leave a separate message for a specific person while using an answering machine because the same greeting should be sent to everyone who makes the call with the same greeting. Had no problems.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is to separately record a message if a predetermined telephone number and an incoming telephone number match when a missed call is automatically answered. The present invention provides a method for selectively sending a response message of a telephone capable of answering a call.

In order to achieve the above object, the present invention provides a first step of writing specific phone numbers and corresponding phone number response messages in a standby state of a phone, and a ring signal is input after the first step. A second step of checking whether the received incoming phone number is in a previously stored phone number; and if it is confirmed by the second step that the currently received phone number matches a specific phone number, a specific response message corresponding to the corresponding phone number And a fourth step of transmitting a common response message when it is confirmed that the telephone number currently received by the second step does not match a specific telephone number. to provide.

Referring to the accompanying drawings, the operation of the selective response message transmission method according to the present invention configured as described above will be described in detail as follows.

First, a method of selectively sending a response message using a caller ID will be described with reference to FIGS. 1 to 5.

It consists of two processes: recording a response message and sending a stored response message.

5 is a table showing an example of message transmission according to a telephone number.

So, if a phone number is first inputted to an empty address, this phone number is stored in the phone number memory section 14. This phone number works in the same way as a speed dial on an existing phone. When one telephone number input is completed (for example, 123-4567 telephone number 1), a corresponding response message is recorded through the microphone 17.

This response message is for broadcasting through the speaker when the telephone number received by the trunk line matches the telephone number registered in advance. The response message is converted into a digital signal through the DSP unit 18 and stored in the address corresponding to the telephone number. Finally, record a public message to answer the normal call.

This process is repeated repeatedly to complete the response message table as shown in FIG.

When the user is absent, the automatic response function is performed by the following operation. Normally, the telephone is in a state of continuously detecting a ring incoming signal from the trunk line.

Thus, when a ring is received, the caller ID signal is transmitted from the telephone station to the ring receiver between the ring signal and the ring signal.

The caller ID signal is extracted by the caller ID unit 11 and transmitted to the CPU 12.

If the call is not answered during the specified number of rings, an operation for sending an auto-answer message is performed. The incoming phone number is from the calling party and the phone number is searched for in a pre-registered table. Searches from the first address of the phone number memory unit 14 to the last address sequentially and repeatedly searches whether there is a matching phone number. If there is a matching phone number, the corresponding address is found. There is no such address. For example, if the received telephone number is 777-7777 of FIG. 5, the corresponding address is 2.

If there is a matching telephone number, a response message corresponding to a given address is called out from the voice storage memory unit 19, converted into an analog signal by the DSP unit 18, and then transmitted to the caller through the trunk line. Since this response message is a predefined response message, the sender can easily respond to this message.

On the other hand, if there is no matching phone number, a public response message is sent and the caller can respond.

This operation is repeated until the handset is made.

Meanwhile, a method of selectively sending a response message using a DTMF signal will be described in detail with reference to FIGS. 1 and 8 to 10.

First, when recording a response message, the normal response message recording operation is the same as the existing operation, but a specific message recording operation that can be left to a specific person and a phone number registration operation used to confirm the right to confirm a message so that the user can deliver the message only to a desired person. This is the difference.

This operation will be described in detail.

When the specific message recording button is input in the standby state, the answering machine sends a message to the user on how to record the specific message and enters the specific message recording mode. When the automatic answering phone enters the specific message recording mode, the message recording operation is terminated by the stop button.When the recording operation is finished, the phone number registration mode is sent after sending a message to the user to register the telephone number to which the specific message is to be delivered. To enter. So when the phone number registration is completed, the answering machine checks the recorded contents and the registered phone number through the speaker and returns to the standby state.

After a general answer message and a specific message to be delivered to a specific person are recorded and the CO line is ringed on the answering machine, the answering machine sends out a ring tone through the speaker, and the answering machine answers the specified number of rings (usually four times). Check for incoming calls. Therefore, when a continuous ring of a predetermined number of rings is received, the answering machine connects the off-line line (off-hook) and sends a message to the phone line to enter the telephone number of the caller.

So when the caller enters a phone number, it checks whether the caller's phone number matches the registered phone number. If the telephone number of the caller does not match the registered telephone number, the general answering message is sent like the conventional answering machine and the answering function is recorded after recording the message using the same operation as the conventional answering machine. To exit.

If the input telephone number matches the registered telephone number, the recorded specific message is sent to the telephone line to deliver the message to be delivered to a specific person. Or VOX signal terminates the auto answer function.

As such, when the missed call is automatically answered, the pre-specified phone number and the incoming call number correspond to a separately recorded message.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the selective response method of the response message of the telephone according to the present invention has the inconvenience that the existing answering machine can not send a separate message only to some specific people by sending the same response message to all the people who make the call. However, according to the present invention, by recording a separate message to a specific person in addition to the general response message, it is possible to deliver a message of a desired content, thereby making it possible to use the automatic response function more conveniently and usefully.

Also, in general, the response message for the absence is for an unspecified number, and there is a general message (for example, I'm going out, so please tell me if you hear a 'beep' sound), but the present invention records a message for a specific person. Because you respond, you have the effect of leaving the right message with the right person.

In addition, the present invention may be a guide message for a specific person, and if there are many family members in the house, a message suitable for each individual may be made, so that one answering machine may use multiple answering machines.
