Apparatus and method for transmitting caller information of communication terminal {Method And Apparatus for Caller Identification Transmitting In Communication Teminal}

The present invention relates to a caller information display apparatus, and more particularly, a mobile communication terminal set in a called party subscriber terminal after extracting caller information included in a call connection request from outside applied to a wired / wireless subscriber station. An apparatus and method for transmitting caller information of a communication terminal to transmit information of a caller by text or voice to a communication device are provided.

In general, when a call connection request is received from any party to a wired / wireless subscriber terminal through a public telecommunication network, the user of the terminal receiving the call connection can selectively respond to a desired call. In order to protect the called party from violence, caller information service is provided to display the caller's information, name, phone number, date, time, etc. on the called party's terminal so that the caller can recognize it.

This can be seen in the accompanying Figure 1, the telephone number of the destination terminal (3) that the user of the calling terminal (1) connected to the PSTN (Public Switched Telephone Network: 2) wired / wireless to the call connection When dialing, PSTN 2 analyzes DTMF signal applied from originating terminal 1 to switch the path for call connection with called terminal 3 and then connects between first and second ring. Information about the calling party terminal 1 detected through analysis of the DTMF signal, that is, the name of the calling party, the calling party's telephone number, the calling time, etc. are included through frequency shift keying, and the incoming call is switched. It transmits to the side terminal 3.

At this time, the incoming ring detection unit 3a of the called terminal 3 detects the incoming ring signal applied from the tip and the ring terminal from the PSTN 2 as shown in FIG. 2. To notify the user of the called party's terminal 3 that the incoming call requesting the call connection is applied through the ring tone transmitting means, and the caller information extracting unit 3b receives the first incoming call detected by the incoming ring detecting unit 3a. The information of the sender included through the frequency shift modulation between the ring and the second incoming ring is extracted and then restored to be processed to a predetermined state necessary for display, and then applied to the display unit 3c made of LCD or LED.

The display unit 3c displays the information of the caller authorized by the caller information extracting unit 3b, that is, information on the caller's name, telephone number, calling time, and the like, and instructs the user of the called terminal 3.

As described above, while the ring is transmitted through the ring tone transmitting means and the caller's information is displayed through the display unit 3c, the user of the called terminal 3 confirms the displayed caller's information and recognizes it as the other party necessary for the call. When the handset of the terminal is off-hook, a loop is formed in which the caller terminal 1 and the called terminal 3 can communicate through the relaying of the PSTN 2.

In addition, as shown in FIG. 3, a user of the called terminal 3 may call the called terminal 3 through the PSTN 2 while setting his / her wireless pager number to go out. When an incoming signal requesting the connection is detected, the called party terminal 3 transmits a message indicating that call forwarding to the radio pager is set to the calling party terminal 1 requesting the call connection via the PSTN 2, and then sets the call. The number is dialed automatically and applied to the PSTN 2 side.

At this time, the PSTN 2 determines the position of the call number applied from the called party terminal 3 and then calls the wireless pager set in the called party terminal 3 through the relay of the base station 4 to call the calling party terminal 1. Connects a call with a radio call period.

Then, the user of the calling party terminal 1 transmits its own phone number and the necessary message to the pager to which the call is connected according to the voice message received in the automatic response.

In the conventional caller information call forwarding device as described above, there is a problem in that the information of the incoming caller cannot be confirmed when the user of the called terminal is absent. Since the user of the calling terminal inputs a new message and telephone number to be left according to a voice message required by an automatic response, there is a problem that a troublesome problem occurs.

The present invention has been made in view of the above-mentioned general problems, and an object thereof is to set the receiving party's information to be transmitted to his portable terminal in response to a user's outgoing connection through a wired terminal. The information of the caller included in the incoming signal is automatically connected to the portable terminal and output as text or voice.
