Perform overall operation control related to various functions.

The modulator and demodulator (MODEM) 102 performs modulation / demodulation of signals for incoming / outgoing call signals and transmitting / receiving data signals through a public telephone network (PSTN) 200.

The Dual Tone Multi-Frequency (DTMF) detector 103 detects the DTMF signal to detect a CID, which is an outgoing telephone number corresponding to a call signal received from the public telephone network 200 through the modulation / demodulation unit 102.

The memory unit 104 inputs / outputs the data generated according to the operation of the phone, such as key data corresponding to the detected CID, and a phone number input by the phone user input through the key input unit 108 and an auto answer mode. RAM for storing voice message data, and a ROM for storing algorithms for controlling the operation of the phone and implementing functions.

The liquid crystal display 105 is to provide a CID for a call signal received by a telephone user using the CID detected by the DTMF detector 103 at the central processor 101. Among the telephone number data stored in 104, the matching telephone number and corresponding telephone number storage information are displayed together or only the detected CID is displayed.

The ring generating unit 106 transmits an incoming sound to inform the outside of the incoming call of the call signal through the modulation / demodulation unit 102 in the central processing unit 101.

The CID transmission unit 107 designates a mobile communication terminal telephone number input by the user through a key input unit as an incoming telephone number, and is ring generation unit 106 that is transmitted according to a call signal received through the modulation / demodulation unit 102. When the incoming call is transmitted for more than a certain time, the central processing unit 101 catches the trunk line of the public telephone network (PSTN) 200 capable of transmitting the call signal and transmits the call signal to the designated telephone number including the detected CID. .

The call signal consists of a designated called telephone number, an identifier and a CID, and includes an identifier so that the called telephone number and the CID are distinguished when the detected CID is transmitted to the designated called telephone number.

This identifier allows the incoming call number of the call signal received from the mobile communication terminal center and the detected calling number to be distinguished. The identifier indicates a CID set by a symbol such as # or * or set by a predetermined bit.

For example, if the identifier is the # symbol and the CID detected by the telephone set to the designated incoming telephone number is 019-111-1234, 02-123-1234, then the CID transmitter 107 of the telephone sets the call signal to 0191111234 # 021231234. It generates and transmits to the corresponding mobile communication terminal center (MSC) (300).

The mobile communication terminal center 300 according to the present invention determines whether there is an identifier set in the received call signal, detects an added CID when the identifier exists, and detects the detected CID by a short message center (SMSC) 500. Send a short message written with the CID detected by the called phone number corresponding to the received call signal.

The method of the present invention configured as described above comprises: an incoming telephone number setting step of inputting an incoming telephone number for receiving a CID of a call signal that is missed by a telephone 100 user capable of detecting and transmitting a CID; A CID detection step of detecting a CID from an incoming call signal when a ringing tone for the incoming call signal transmitted from the telephone 100 is transmitted for a predetermined time; A call signal transmitting step of transmitting the detected CID together with the call signal to the designated telephone number; The mobile communication terminal center 300 receiving the transmitted call signal detects the CID through the identifier, and transmits a short message sent to the designated telephone number.

It is determined whether or not the telephone 100 user is absent through whether the incoming ring tone is continuously transmitted for a predetermined time or more (S4).

If it is determined that the ringing tone transmission stops and is not in the absence of being hooked on, it ends. If the ringing tone continues to be absent, the CID is detected by the DTMF signal of the incoming call signal through the DTMF detection unit 103 ( S5).

The central processing unit 101 transmits the detected CID and the called telephone number designated by the user to the CID transmitter 107 to generate a call signal to the called telephone number combined with the identifier (S6).

If the detected calling number is 02-987-9876, the central processing unit 101 of the telephone sends a call to the number designated with the identifier (#), 02-987-9876, which is the CID detected by the CID transmitting unit 107. In addition to the signal, a call signal is generated with 0191231234 # 029879876 combined with the incoming telephone number 019-123-1234.

The central processing unit 101 determines whether there is an empty trunk line in the public telephone network (PSTN) 200 for transmission through the CID transmitter 107 of the generated call signal (S7). The call signal is transmitted to the designated incoming call number through the corresponding trunk line (S8).

The transmitted call signal is transmitted to the mobile communication terminal center 300 corresponding to the designated called phone number (S9).

Upon receiving the call signal, the mobile communication terminal center 300 detects the CID through the identifier added to the call signal, and detects the detected CID 02-987-9876 and the call phone number 019-123-1234. The short message is sent to the center 500 (S10).

In the short message center 500, the received CID is entered in the message field, and the incoming phone number is input to create a short message. The terminal phone number 019-123-1234 is the corresponding incoming phone number through the mobile communication terminal center 300. Transfer to (S11).

The mobile communication terminal user checks the CID of the incoming call to his / her own phone through the incoming short message (S12).

In another embodiment, the CID detected from the call signal received by the telephone is searched for a matching telephone number among the telephone numbers stored in the memory of the telephone, and the received call signal composed of the retrieved telephone number and the stored name of the telephone number is searched for. Sends outgoing information about the call with a call signal to the designated destination number.

If the outgoing information transmitted in this way is transmitted to the telephone user in a short message, the telephone user can more conveniently confirm the missed incoming telephone information.

In another embodiment, a telephone capable of setting an auto answer mode may include not only the CID of an incoming call signal but also data indicating whether or not a voice message is left in the auto answer mode by a caller together with a call signal to a designated called phone number. By transmitting, the mobile communication terminal, which is the called phone number, displays together with the short message the CID of the missed call and the presence / absence of the corresponding voice message.

Through the short message transmitted in this way, the phone user can check in real time the presence or absence of the CID and voice message of the incoming call.

In another embodiment, the CID transmitter of the telephone capable of setting the auto answer mode compresses a voice message left by the caller and transmits the voice message to the mobile communication terminal center together with the detected CID, and through the call signal received from the mobile communication terminal center. Send a short message created with the detected CID.

In addition, the voice message is detected from the incoming call signal and uploaded to the wireless Internet server of the mobile communication terminal center 300.

The terminal user who checks the received short message selectively downloads and confirms a voice message of the caller stored in the wireless Internet server.

As described above, the present invention transmits a CID for a call signal received at the missed telephone through a short message to a designated mobile communication terminal through a CID transmitter provided in the telephone, so that the telephone user is received at his or her telephone remotely.
