Abstract

PURPOSE: An apparatus for notifying originator information received in an absent state is provided to automatically transmit the originator information according to a call received during the absent state to a communication terminal, so as to perceive the received call in a location distant from the communication terminal. CONSTITUTION: A communication terminal performs an off-hook operation if a telephone ring is over a constant frequency in a call terminating process. The communication terminal transmits an input request message relating to originator information received in an absent state to an originating side. The originator information is detected, the communication terminal stores the originator information and performs an on-hook operation. The communication terminal dials a preset phone number which is a target of a call received in the absent state, after constant time. If a terminating side performs an off-hook operation by responding to the dialing, the communication terminal synthesizes voice data relating to the off-hook operation with voice data relating to the originator information, then informs a call receiving notifying message as a voice.

Description

Missing caller information notification device and method {APPARATUS AND METHOD FOR TELLING CALLER ID IN ONE 'ABSENCE}

The present invention relates to an apparatus and method for notifying caller information of a communication terminal, and more particularly, to an apparatus and method for notifying a caller information received when a user is absent to the user's communication terminal.

In general, a method of confirming a missed call by a user has been possible only in a communication terminal having an answering device. A communication terminal having such an answering device stores a voice left by a sender in a voice memory or a tape using a digital signal processor (DSP). The voice message stored in this way can respond to the missed call only when the user checks the message stored in the voice memory and the magnetic memory after returning home.

As described above, since the user can check the message stored in the answering machine for the missed call after returning home, the user cannot immediately confirm or answer the missed call.

Accordingly, an object of the present invention is to provide a missed caller information notification device and method for notifying a caller information of a missed received call to a phone number preset by a user when a call is received when the call is missed.

1 is a block diagram of a landline telephone having a missed caller information notification device according to an embodiment of the present invention.

Hereinafter, the configuration will be described with reference to FIG. 1. First, the controller 10 manages the overall operations. In addition, the controller 10 may be implemented as a one chip microprocessor. The key input unit 15 has a plurality of numeric keys and function keys, and generates key data for the keys. The memory 20 includes a ROM for storing a predetermined operating program, a RAM for temporarily storing data generated during the execution of the operating program, and an electrically programmable EEPROM. In particular, the memory 20 stores a telephone number for transmitting caller information in the caller information transmission mode and a caller dialing number input by the caller. The line interface unit 30 is connected to the telephone lines Tx and Rx and interfaces the signals coming through the telephone lines. The ring detector 40 detects a ring signal from a signal input through the line interface unit 30. The hook controller 50 controls the hook on / off under the control of the controller 10. The DTMF detecting unit 60 detects a DTMF (Dual Tone Multiple Frequency) signal from the signal interfaced from the line interface unit 30 and outputs it to the control unit 10. The DTMF generator 70 generates a DTMF signal under the control of the controller 10. The voice memory 85 stores DTMF data stored in the memory 20 and voice data for the first and second hook-off signals as shown in FIG. The voice controller 80 synthesizes and outputs voice data stored in the voice memory 85 under the control of the controller 10. The voice processor 90 receives and processes the voice signal output from the voice controller 80 or the DTMF signal output from the DTMF generator 70, and transmits the voice signal to the telephone line through the line interface unit 30.

2 is a flowchart illustrating a missed caller information notification method according to an exemplary embodiment of the present invention.

Referring to FIG. 2, first, a user should store a phone number in the memory 20 for receiving missed caller information in order to realize the present invention.

When a predetermined key is input from the key input unit 15, the controller 10 sets a caller information transmission mode in step 201. After setting the sender information transmission mode in step 201, the controller 10 checks whether a ring signal is detected through the ring detector 40 in step 203. At this time, if a ring signal is detected from the ring detector 40, the controller 10 generates a predetermined number of ring sounds in step 204 and counts the number of ring sounds. After the predetermined number of rings, the controller 10 proceeds to step 205 and controls the hook controller 50 to perform a first off hook (hereinafter referred to as “first hook off”). If the hook is off, the controller 10 proceeds to step 207 and controls the voice controller 80. The voice controller 80 generates an eleventh address signal for the first hook-off under the control of the controller 10, and sends a caller information input request message from the eleventh address of the voice memory 85 (e.g. Please press your phone number ") and transmit it to the telephone line through the voice processing unit 90 and the line interface unit 30. In addition, after transmitting the caller information input request message, the controller 10 counts the timer 12. After step 207, the controller 10 checks whether the caller inputs caller information in response to the caller information input request message (step 209). When the caller information signal, that is, the caller's telephone number, is input as a DTMF signal, the controller 10 proceeds to step 211 to initialize the counted time, converts the DTMF signal into corresponding digit data, and stores the same in the memory 20. . Then, the controller 10 proceeds to step 215 and controls the hook controller 50 to on hook and count the timer 12. However, if the DTMF signal is not input, the controller 10 In step 212, the controller 10 checks whether the DTMF signal is exceeded within the first predetermined time. In step 212, the control unit 10 proceeds to On Hook. Quit.

In step 215, the controller 10 checks whether the timer time counted after the on-hook in step 213 exceeds the second predetermined time. If the second time exceeds the second predetermined time, the controller 10 hooks off in step 217. Initialize the timer. After step 217, the controller 10 proceeds to step 219 to read the phone number previously stored in the memory 20, and controls the DTMF generator 70 to store the phone number stored by the user in the memory 20. Read from). When the phone number is read, the controller 10 determines whether the phone number is a pager number in step 221. If the telephone number is not the pager number, the controller 10 proceeds to step 223 to dial the telephone number. After the dialing, the controller 10 determines whether ring back tone and busy tone signals are detected in steps 225 and 226. In this case, when the ringback tone is detected, the controller 10 proceeds to step 227, and when the busy tone is detected, the controller 10 returns to step 213 and repeats the subsequent process. The controller 10 proceeds to step 227 to count the time by driving the timer 12, and proceeds to step 229 to check whether the communication terminal of the telephone number is hooked off. At this time, if the hook-off (hereinafter referred to as "second hook off") is detected, the controller 10 proceeds to step 231 and reads out of the stored digit data from the memory 20. Then, the voice control unit 80 is controlled to read voice data corresponding to the digit data from the voice memory 85 shown in Fig. 3, and to read voice data for the second hook off. In addition, the voice controller 80 synthesizes the voice data for the digit data and the voice data for the second hook-off and transmits a call reception notification message to the telephone line via the voice processor 90 and the line interface unit 30. After transmitting to the communication terminal of the pre-stored phone number through the hook control step 50 in step 241 on the hook.

For example, if the caller's telephone number is "123-4567", the voice controller 80 is controlled by the controller 10 and voice data from the first address to the seventh address of the voice memory 85 and the second address. The voice data of the twelfth address of the hook-off signal is read, and the voice data is synthesized and transmitted through the telephone line via the voice processing unit 90 and the line interface unit 30, and "one or two and three-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-six-sixty-six-six-six-six-sixty-six-six-sixty-six-sixty-sixteenths of sixty-sixth-sixth-speech

On the other hand, if the counterpart hook-off is not detected in step 229, the controller 10 proceeds to step 230 and checks whether the timer time counted in step 227 exceeds the third predetermined time. If the timer time exceeds the third predetermined time, the control unit 10 proceeds to step 241 and ends on hook.

On the other hand, if the telephone number input by the user in step 221 is the pager number, the controller 10 proceeds to step 233 and dials the pager number. After the dialing, the controller 10 checks whether the wireless call service center is hooked off in step 235. When the wireless call service center is hooked off, the controller 10 proceeds to step 237 and transmits a DTMF signal for a key "2" after a predetermined time. After step 237, the controller 10 proceeds to step 231 after a predetermined time and transmits a call reception notification message as described above.

As described above, the present invention has an advantage in that it is possible to cope with the received call without missing the received call even if the call is far away from the received communication terminal by automatically transmitting the caller information on the missed received call to the communication terminal of the user. .
