The present invention relates to an automatic answering telephone terminal, and more particularly, to a method in which a visitor automatically makes a telephone call or leaves a visitor's message with an absent visitor through an intercom.

Conventionally, when a visitor visits a home, they press a doorbell installed at a door. If the doorbell is pressed and no one is in the home, the visitor just has to go back. If the visitor is in a hurry to speak to a visitor at home (for example, the homeowner), this situation would be very embarrassing.

In this situation, if the visitor can be contacted by the absent visitor in any way, this distress can be somewhat (or completely) resolved.

Accordingly, an object of the present invention is to provide a method for automatically making a phone call with a visitor who is not present.

It is another object of the present invention to provide a method for leaving a visitor's message to a visitor who is absent.

Another object of the present invention is to provide a method of automatically conducting a telephone call with an absent visitor or leaving a visitor's message to the visitor.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a fixing device for a radiotelephone according to the present invention. The control unit 110 controls the overall fixing device of the radiotelephone. That is, the control unit 110 forms a call loop to the handset 144 of the fixing device when the hook switch 112 is detected to be hooked off, and detects the key when the key is input from the key input unit 140. The circuit 130 forms a currency loop. The hook switch 112 connects and blocks the telephone line and the call circuit unit 114 under the control of the controller 110 according to lifting or lowering of the user's handset. The call circuit unit 114 forms a predetermined call line under the control of the controller 110. The RF transmitter / receiver 116 is connected to the call circuit unit 114 and wirelessly transmits and receives various tone signals and voice signals to a portable device of a wireless telephone. The DTMF generating unit 118 converts key data corresponding to the telephone number pressed by the user under the control of the first control unit 110 into a DTMF (Dual Tone Multi-Frequency) signal and outputs it to the call circuit unit 112. do. The tone detector 120 detects various tone signals applied from the call circuit unit 114 and outputs them to the controller 110. The VOX circuit 122 is connected between the call circuit unit 114 and the control unit 110 and detects the presence or absence of a voice signal in the phone call state and informs the control unit 110. The cortec 124 is connected in parallel between the call circuit unit 114 and the RF transmitter / receiver unit 116 and converts an analog signal into a digital signal and provides the digital signal to the digital signal processor 126 or outputs from the digital signal processor 126. The digital signal is converted into an analog signal and provided to the call circuit unit 114. The digital signal processor 126 analyzes the digital signal applied through the codec 124 under the control of the controller 110 and stores the digital signal in the voice storage unit 128 or synthesizes voice data stored in the voice storage unit 128. To the codec 124. The voice storage unit 128 stores or reads the voice data under the control of the digital signal processor 126. The speakerphone circuit 130 forms a speakerphone call loop by connecting the call circuit part 114, the microphone 132, and the speaker 134 when a speakerphone key is input or there is a key input in the automatic call mode. The microphone 132 outputs an electrical signal corresponding to the voice of the user to the speakerphone circuit 130 in the speakerphone mode. The speaker 134 transmits voice to the user under the control of the speakerphone circuit 130. The ring detector 136 detects a ring signal input through a telephone line and provides the ring signal to the controller 110. The memory unit 138 stores function tables for servicing various functions provided by the wireless telephone and data under the control of the controller 110. The key input unit 140 includes a plurality of keys, and applies key data to the controller 110 in response to a user's key input. The display unit 142 displays data provided from the control unit 110. The handset 144 is connected to the call circuit 114 by wire, and plays or transmits a voice signal during a general telephone call through the fixing device.

In FIG. 1, the circuit shown in block 160, i.e., the interphone circuit 140, the interphone microphone 146, the interphone speaker 148, and the doorbell switch for making a call connection with an absent visitor, which is a feature of the present invention. 150) is further provided. Thus, the circuits in block 160 are installed at the gate for the visitor. The doorbell switch 150 is operated when the visitor presses the doorbell. When the doorbell switch 150 is pressed, the control unit 110 transmits a bell to people in the house through the speakerphone circuit 130. The interphone microphone 146 and the interphone speaker 148 are provided so that the visitor can talk to the user of the cordless phone (a person in the house).

2 is a control flow chart for conducting a telephone call with a visitor who is absent according to the present invention, FIG. 3 is a subroutine flowchart of the memo recording function mode of the present invention, and FIG. Call flow mode subroutine flow chart with.

A user who is now at home must first register this in order to provide a telephone call service to a visitor according to the present invention. First of all, the visitor answering function is set using the MMC (Man Machine Communication) function. Visitor auto-response means that even if the homeowner is not at home, the visitor presses the doorbell to provide the recorded message voice call. The automatic answering function is classified into a function that allows a message visitor to simply record a memo on an automatic answering wireless telephone and a function to form a telephone call with a visitor who is not present. In order to establish a telephone call with the missed visitor, the service registrant must register the missed outgoing telephone number in the memory 138.

It is noted that the above-described service registration control is already known, and in the present invention, registration control is performed to achieve the present invention.

In accordance with the above registration, the operation of the present invention is performed as follows.

First, when the visitor presses the doorbell installed at the door to visit the house, the doorbell switch 150 of FIG. 1 is turned on, and the corresponding data is applied to the controller 110 via the interphone circuit 144 and the call circuit 114. . The controller 110 detects whether data corresponding to the visitor's doorbell pressing is applied in step 202 while in the standby state as in step 200. If it is detected, the controller 110 proceeds to step 212 to determine whether the visitor auto-response function is set in the memory 138. If the function is set, the control unit 110 performs step 212, and otherwise performs step 206.

In step 206, the controller 110 controls the speaker phone circuit 130 to transmit a ring tone to the speaker 134. Then, the digital signal processor 126 and the speakerphone circuit 130 are controlled to send a message to the people in the house that the visitor came. In response, when a person in the house picks up the handset 144 or presses a key corresponding to a speakerphone call, that is, detects a hookoff in step 208, the control unit 110 proceeds to step 210 in which the visitor communicates with the person in the house. Make an internal call.

However, if the visitor auto-response function is set in step 204, the control unit 110 performs step 212. When the visitor autoresponder is set up, it means that there is no one in the house to welcome visitors. In step 212, the controller 110 controls the digital signal processor 126 to provide a visitor with a message for performing a function. The guide message is a command for key input to perform a function. Press the doorbell five times to record a memo, and press the doorbell 10 times to make a telephone call with the missed visitor.

Therefore, when the visitor hears the message sent out and inputs a function execution key (for example, presses the doorbell a predetermined time), the visitor determines whether the key corresponding to the function execution is authorized in step 214, and then the user inputs the function execution key in step 218. It is determined whether the key data corresponds to the memo recording function. If it is determined in step 218 that it corresponds to the memo recording function (for example, pressing the doorbell five times), the process proceeds to step 220 to perform the memo recording function mode.

The subroutine of the memo recording function mode of step 220 is shown in FIG. Referring to FIG. 3, the controller 110 transmits a memo recording function command message to the visitor in step 300 of FIG. 3. For example, please record a message to leave. The visitor will enter his or her message, and accordingly, the controller 110 determines whether the message is authorized in step 302. If the message is applied, the control unit 110 proceeds to step 304 to control the digital signal processing unit 126 to store the message in the voice storage unit 128. In step 306, the controller 110 checks whether the recording is completed. When the recording is completed, the control unit 110 maintains the standby state in step 308, and returns to the main routine of FIG. The controller 110 ends the process when the memo recording function mode is performed in step 220 of FIG. 2.

On the other hand, if the key data corresponding to the memo recording function of step 218 of FIG. 2 proceeds to step 222, the control unit 110 determines whether the key data corresponding to the telephone call function with the missed visitor. If the control unit 110 determines that the key data corresponding to the telephone call function with the missed visitor (for example, presses the doorbell 10 times), the control unit 110 proceeds to step 224 and the call with the missed visitor. Perform the function mode.

The subroutine of the call function mode with the missed visitor in step 224 is shown in FIG. Referring to FIG. 4, the controller 110 reads the outgoing telephone number of the missed visitor directly from the memory 138 in step 400 in response to key data corresponding to the telephone call function with the missed visitor. Thereafter, the mobile station proceeds to step 402 to perform automatic dialing as the read-out telephone number. That is, the call circuit unit 114 is controlled to form a call path, and the DTMF generator 118 transmits the DTMF signal corresponding to the telephone number.

If the visitor receives a call at the outgoing place, a call is formed as in step 404, and the visitor and the visitor at the outgoing place perform a call as in step 410. When the call is ended after the call is completed, the controller 110 checks this in step 410 and enters the standby state as shown in step 414. Then return to the main routine of Figure 2. The controller 110 terminates the process when all of the call function modes with the missed visitor are performed as shown in FIG. 4 described above in step 224 of FIG. 2.

As described above, the present invention has the advantage that a visitor can automatically make a phone call or leave a visitor's message through an interphone installed at the main visitor and the visited visitor.
