The ring signal detector 210 detects a ring signal signal transmitted through a telephone line to notify the controller 220 of an incoming call, and the controller 220 is a one chip microprocessor including a memory. Overall control of the overall operation of. The control unit 220 has a predetermined timer 221, the timer 221 is driven when the ring signal detection unit 210 detects that the communication path is formed, from this time when the communication path is released To provide a reference time of all the operation of the device 200.

When the hook switch converter 270 detects a ring signal signal through the ring signal detector 210, the hook switch converter 270 converts the hook off state to a hook off state without maintaining the telephone handset and maintains the call path. If the caller's voice is not recognized, the call is switched to Hook On state to terminate the call.

The voice recognition unit 260 recognizes whether the caller's voice is input at the predetermined step and transmits the result to the control unit 220.

The storage unit 240 stores a guide message to be sent to the caller, and the guide message stored in a digital form is converted into an analog voice by the voice synthesizer 230 and sent to a caller and a receiver through a telephone line and a speaker, respectively. do.

The codec unit 250 may record a kind of guidance message desired by the user as one's own voice or another person's voice, and the voice is finally stored in the storage unit 240 in the form of a digital signal.

5 is a flowchart illustrating a process of verifying an identity of a caller with a caller identification device of the present invention.

When the ring signal detector 210 detects the ring signal signal for the prescribed number of times in step 401, the ring signal detector 210 transmits the detected information to the controller 220, and the timer 221 operates in step 402. Start to provide a reference time for each step. In addition, in step 403, the control unit 220 receiving information from the ring signal detection unit 210 switches the hook switch conversion unit 270 to a hook off state so that a call path is formed.

In step 404, the caller can hear the first guide message sent out (e.g., Hello? 00 company. Please tell me the name of the person you are looking for). In this case, if you enter the number of the called party through the number pad (key pad) of the called party phone 100 when storing the guide message, the guidance message containing the called party's number (e.g., how are you? The telephone number you call is 000-OOOO. Please tell us the name of the person you are looking for.)

When the caller speaks his / her identity or the name of the person seeking the message according to the guide message, the controller 220 checks whether the caller's voice is input in step 405 and proceeds to step 406 if it is input. Let's do it.

In step 406, the second announcement message (e.g., please wait a moment) is sent simultaneously to the caller and the speaker. In this case, if the receiver wants to talk, the receiver picks up the handset in step 407, the normal call is made in step 409, and if the receiver does not want to talk, the third guidance message (for example, because he is absent now), Please try next time), and all the operations will be finished.

On the other hand, according to another embodiment of the present invention, in steps 406 and 407 of the caller identification process, the person associated with the caller recognizes the caller's voice and attempts to make a direct call so that an unrelated person receives a call to the person concerned. You can eliminate the inconvenience of changing the phone.

In addition, according to another embodiment of the present invention, when the ring signal is detected, the ring signal detection unit 210 for switching the hook switch to the Hook Off state to maintain the call in the state of lifting the handset and Hook switch conversion unit 270, a storage unit 240 for storing a guide message to be sent to the caller in each step to confirm the identity of the caller, a voice recognition unit 260 for recognizing the presence of the caller in each step, The voice synthesizer 230 and the ring signal detector, the hook switch converter, the storage unit, the voice recognition unit and the voice synthesizer 230 convert the digital information output from the storage unit 240 into a form of voice under a predetermined control. The controller 220 controlling the signal processing in the speech synthesizer may include a monolithic microwave integrated circuit or a hybrid microwave integrated circuit. It may be manufactured as an integrated circuit device of a hybrid microwave integrated circuit. The integrated circuit device is an integrated circuit device for a transmission / reception chip of a cellular phone in a high frequency region of the 800 MHz band or a personal mobile communication device (PCS) in the 1.8 GHz band. This identification function is performed by a read only memory (ROM) on a transmission / reception chip of a conventional cellular phone or a code division multiple access (CDMA) or time division multiple access (TDMA) personal mobile communication device (PCS). It is implemented by a device embedded in the form.

Calling party identification device and method of the present invention is economical compared to the existing caller ID display function (aka Caller ID), there is an advantage that there is no regional limitation.

In addition, since the identity of the caller can be identified before the call is made in a small office without a private branch exchange (PBX), it is possible to eliminate the inconvenience that an unrelated person receives a call and changes the call to a related person.
