Caller ID service transmits caller ID information together with ring signal, so that the telephone user (receiver or called party) equipped with the digital processing device before calling the receiver off hook. It is a service to check the caller ID information such as, address.

In the United States, in 1987, CLASS (Custom Local Area Signaling Services) was provided to start the caller ID service. Currently, most telephone companies develop and provide various package services based on the caller ID service. In Europe, the caller display service was introduced in 1991, and in Japan, the telephone number display commercial service was launched nationwide in 1998.

Caller ID service enables the modeling of new business using telephone network by converting caller-oriented communication environment to receiver-oriented communication environment. Telemarketing, database marketing industry can be invigorated, and the advantages of the telephone receiver as well as the protection of the business is highlighted. For example, a company can more easily accumulate a database of customers who have made phone calls, and can check customer information in advance before responding to a customer, thereby identifying and responding to new or bad customers. In addition, when the caller is not connected, the caller information is automatically stored without having to leave a contact number separately.

Currently, in using such caller ID service, a mobile phone includes a caller ID device to provide a service, but it is not generalized. In general, a known caller ID device is equipped with an LCD and has two to three lines. Caller ID information is provided through a string. These devices have to have the phone in hand to respond immediately to the reception of the ring signal, or look directly at the LCD to see what is stored in the memory. However, in addition to checking the message left by the caller individually on the existing answering machine, when the remote user checks the incoming call to his office or home, the screen is displayed to use the memorized caller ID information. Other telecommunication control means are required.

Accordingly, there is a need to provide a caller ID device that can remotely check caller ID information by voice through a telephone communication network.

The telephone line interface means 100 is connected to a communication network and performs a telephone line interface function.

The receiver 200 is connected to a communication network, and receives and detects an incoming signal transmitted through the connected communication network.

The control unit 300 includes an incoming signal processing stage 310, an input / output data processing stage 330, and a microprocessor 320, and the incoming signal processing stage 310 interprets and demodulates the detected incoming signal to caller ID. Generates information and inputs the generated information into the memory unit 600 which is a data storage space.

Hereinafter, the configuration of the present invention will be described in more detail with reference to FIG. 2.

2 is a view showing the overall configuration of an embodiment of the apparatus 700 for providing caller ID information according to the present invention.

Referring to FIG. 2, as described above, the apparatus 700 for providing a caller ID information according to the present invention includes a telephone line interface unit 100, a receiver 200, a controller 300, a voice codec 400, and a screen display unit ( 500 and the memory unit 600, the receiving unit 200 is composed of DTMF receiving means 210, FSK receiving means 230 and ring signal detection means 220. The control unit 300 includes an incoming signal processing stage 310, a microprocessor 320 and an input / output data processing stage 330. The incoming signal processing stage 310 includes a decoder 311 and an incoming signal designation means 312. , A signal counter 313, a timer 313, and an incoming signal input means 314, and the input / output data processing stage 330 includes a DSP 331 and a ROM 332.

The telephone line interface means 100 is connected to a communication network and performs a telephone line interface function. That is, an incoming signal including a ring signal, an FSK signal, and a DTMF signal transmitted through a communication network is transmitted to the receiving unit 200 through the telephone line interface means 100, and the telephone line interface means 100 is also connected to the telephone. To match. When a ring signal is received and the receiver off-hooks the telephone receiver, the subscriber matching circuit of the exchange senses the off state of the hook switch and supplies the call current to the receiver's telephone.

The exchange sends a ring signal (75Vrms, 20Hz) to the receiver's telephone through the communication network, and in the case of the telephone, the incoming call is reproduced through the incoming signal unit in the telephone to hear the ringing sound. For reference, the telephone has a basic configuration of a call circuit section, a dial circuit section, an incoming call signal section, and a handset section. The ring signal detecting means 220 detects such a ring signal, and the ring signal is counted by a signal counter 313 which will be described later.

DualTone Multi Frequency (DTMF) receiving means 210 is used to receive a command code from the caller ID information remote identifier. Here, the DTMF signal is generated when the button of the general telephone is pressed and sent to the telephone exchange. The DTMF signal is used for the electronic telephone. On phones with DTMF, each key on the phone you press produces two notes with a specific frequency. To avoid mimicking a voice, a combination of two notes, one belonging to a higher frequency (1209 Hz, 1336 Hz, and 1477 Hz) and one belonging to a lower frequency (697 Hz, 770 Hz, 852 Hz, 941 Hz), is used for each key value (0). ~ 9, *, #, A ~ D). The control unit 300 (a program in the control unit) may use a telephony application program interface (TAPI) to provide a means for detecting a DTMF signal.

The first half-cycle signal of the ring signal is input, and then a frequency shift keying (FSK) signal is transmitted, and the FSK receiving unit 230 receives the transmitted FSK signal. The FSK signal includes caller ID information such as the caller's name, phone number, and address.

FSK is a modulation scheme in which carrier frequencies are differently transmitted in response to digital signals, that is, a frequency modulation technique that combines binary data into one carrier. FSK makes only two changes of zero and one in frequency. FSK is easy to configure and relatively strong for long-distance transmission, so it is widely used in PSTN, and is used for data transmission of 200 ~ 1200 bps at low speed asynchronous.

The incoming signal processing stage 310 included in the controller 300 includes a decoder 311, an incoming signal designation means 312, a signal counter and a timer 313, and an incoming signal input means 314.

The decoder 311 demodulates and detects the FSK signal received by the above-described FSK receiving unit 230. The decoder 311 converts the information modulated into an analog signal into a digital signal for transmission, thereby enabling digital processing in a microprocessor 320 or a digital signal processor (DSP) 331 to be described later. The decoder 311 interprets information by detecting an envelope of the FSK signal.

The signal counter 313 measures the number of times of receiving the ring signal. That is, the signal counter 313 counts the pulse of the received signal itself, and also counts and stores the confirmation signal from the same sender when the signal is repeatedly received in the memory. The ring signal reception count measurement is used to determine a predetermined number of ring signals as a reference when the microprocessor 320 initiates the remote provision of the caller ID information if the receiver does not off-hook the receiver while the ring signal is received. In order to provide the caller ID information, the counting of the incoming signal from the same caller is provided to include the number of times of the call.

The timer 313 has a clock function having standard time information and a time measuring function for this if the microprocessor 320 requires it. For example, the caller ID information providing apparatus 700 may recognize the time at the time of reception and provide the caller ID information to the remote confirmer. When the caller ID information providing apparatus 700 requests the remote verifier to input a password or command code, it is necessary to determine an input available time. The timer 313 provides a time measurement function at this time.

The incoming signal input means 314 inputs the caller ID information analyzed by the decoder 311 into the memory unit 600. The caller ID information includes the caller's name, phone number, address, call time, call count, and the like. The incoming signal input unit 314 may have a function of inputting only newly calculated data without storing the duplicated information by comparing the latest information with existing information stored in the memory unit 600. For example, only the number of times of transmission and the time of transmission are accumulated and stored, without leaving the information such as the name of the caller and the telephone number.

The memory unit 600 may use a flash memory as a space for storing information included in the incoming signal and data calculated by the microprocessor.

The incoming signal designating means 312 realizes an operation function so that the text message and the voice information which have been input in advance with respect to the predetermined incoming signal can be provided correspondingly. The incoming signal designation means 312 is not an essential component in the configuration of the caller ID information providing apparatus 700 according to the present invention, and is for applying the function of the apparatus. In order for the incoming signal designating means 312 to operate, the microprocessor 320 needs to have a function of controlling a memory. As described above, a keypad controlled by the microprocessor 320 and the incoming call designation means 312 may be mounted to transmit a command to the apparatus to combine desired voice information and to input a text message.

The input / output data processing stage 330 includes a DSP 331 and a ROM 332.

The DSP 331 decompresses the digital compression set in the conversion information used to convert the information and data extracted from the memory unit 600 into voice, and converts it into voice information that can be processed and transmitted by the voice codec 400. The extracted information and data are signal processed, and the information and data are signal processed to be displayed on the screen display unit 500.

The ROM 332 stores decompressed voice information and text information necessary for the DSP 331 to decompress digitally.

The microprocessor 320 controls the incoming signal processing stage 310 and the input / output data processing stage 330, executes program code for communication with a remote checker, and controls output data for voice and screen display.

A codec (Coder and Decoder) 400 performs a signal conversion process to transmit the data output by voice through a communication network under the control of the microprocessor 320.

The screen display unit 500 displays data output on the screen under the control of the microprocessor 320. Generally, LCD is used as a screen display means. In this case, the screen display unit 500 includes an LCD driver for driving the LCD. In order to realize a line control function for efficiently using the limited display space of the LCD, the LCD driver may further include a predetermined control chip and a memory chip.

The caller ID information providing apparatus 700 described above is a means for realizing an independent function different from the phone, but for convenience, the parts that perform common functions among the above-mentioned phone internal components are bundled together and installed inside the phone. It may be used.

Hereinafter, a remote verification method of caller ID information according to the present invention will be described in detail with reference to FIG. 3.

3 is a flowchart illustrating a method of providing caller ID information according to the present invention.

First, the ring signal detecting means 220 detects the first ring signal (S100).

Subsequently, the FSK receiving unit 230 receives the FSK signal received together with the ring signal (S110).

Next, the decoder 311 demodulates the received FSK signal (S120), and the incoming signal input unit 314 stores the demodulated information in the memory unit 600. At this time, the incoming signal input means 314 stores the data received from the signal counter 313 and the timer 313 together (130).

Subsequently, the controller 300 extracts information and data from the memory unit 600 and displays the extracted information and data on the screen display means (140).

Next, if the receiver does not off-hook the receiver until the signal counter 313 counts the ring signal and receives the ring signal for a predetermined number of times (for example, three or more times) (S150), the controller 300 sends the caller. Sending a password input request message for the remote identifier of the ID information (S160) receives a password from the remote identifier (S170).

If the receiver off-hooks the receiver before receiving the predetermined number of ring signals in step S150, the telephone loop circuit is connected and the receiver's telephone is in a call state (S200).

After the password input request message is sent, the timer 313 measures the time, and if a password is not input or a wrong password is input even after a predetermined time elapses, the caller ID information providing apparatus 700 ends the information providing procedure ( S170, S180).

If a password is input within a predetermined time and the input password matches, the control unit 300 prompts the user to input a selection code indicating one of the caller and the new caller before the time adjusted by the caller ID information remote checker. Send a message to receive a selection code from the remote identifier, and sends a guide message to input a code for command to provide only specific information of the selected caller ID information as voice information (S190, S210) ).

The type of voice information provided by the input of the selection code may be adjusted in advance through the keypad as described above. For example, it is possible to adjust whether or not a new caller is a caller after which period, or to which group name to simply express the sender's individual information without listing them individually (possibly by the call signal designating means 312). In addition, the specific information of the selected caller ID information is for transmitting only one of 'new name', 'telephone number' or 'address' of the new caller as voice information.

Subsequently, the controller 300 transmits caller ID voice information to the remote identifier through the voice codec 400 (S220).

Finally, the controller 300 transmits a message for inquiring whether to repeat the provision of voice information and a message for guiding a code to be input when the remote checker wants to repeatedly listen (S230), and receives the repeated listening request code. The information is retransmitted (S240).

The present invention has been described above with reference to the preferred embodiments, which are merely examples and are not intended to limit the present invention, and those skilled in the art to which the present invention pertains do not depart from the essential characteristics of the present invention. It will be appreciated that various modifications and applications are not possible that are not illustrated above. For example, each component specifically shown in the embodiment of the present invention can be modified. And differences relating to such modifications and applications will have to be construed as being included in the scope of the invention defined in the appended claims.

As described above, according to the apparatus for providing a caller ID information according to the present invention, the caller ID information can be confirmed through a telephone at a remote location without the caller leaving a message individually.
