The first memory stores at least more than a piece of information of calling terminals, to prohibit access of the main terminals and the sub terminals by a prohibition mode. The second memory stores at least more than a piece of caller information for selectively connecting the sub terminals with the corresponding calling terminal by a selective connection mode. A switch(11) switches signal transmission paths between the main terminals, the sub terminals, and the transmitter/receiver. A controller(7) compares the caller ID information stored in the first and the second memories with caller ID information transmitted from the calling terminal, and decides whether to permit or prohibit the signal of the calling terminal in the prohibition mode and the selective connection mode.

Description

Communication terminal with caller identification and its control method {Correspondence Terminal With Function Of Identifying An Addresser And Method Of Controlling The Same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal having a caller identification function, and more particularly to a communication terminal having a caller identification function for automatically disconnecting an unwanted caller from a receiving party and automatically connecting to a desired receiver at the calling party. .

Economic development and the development of information and communication are opening the era of one-on-one telephones. In addition, as recognition of personal information is important, individual telephones are installed in each room in a home.

In general, a communication network used in a home includes a main terminal connected to one trunk line and a plurality of sub terminals connected to the main terminal and an extension. When the external calling party transmits a ringing tone signal to the receiving party through the public communication network, the ringing tone signal is received by the main terminal. The main terminal generates a predetermined signal informing the receiving side by the ring tone signal of the calling terminal. The predetermined signal causes the receiver to exchange messages with the sender using the handset of the main terminal. If the callee wants to be another person, the callee directly transmits the ring tone signal to the sub terminal of the callee through the extension. By the ring tone signal transmitted to the sub terminal, the corresponding receiver exchanges messages with the caller of the calling party through the sub terminal.

As a result, signals that the receiver does not want, such as a stalker, a dealer's visiting phone and a violent phone, must always be received by the receiver via the main terminal. In addition, the signal transmitted from the calling party is always passively connected to the sub-terminal through the main terminal, resulting in a delay in time and the invasion of personal privacy.

Accordingly, an object of the present invention is to provide a communication terminal having a caller identification function for blocking an unwanted caller's access at the receiver.

Another object of the present invention is to provide a communication terminal having a caller identification function for automatically connecting to a desired receiver at the calling party.

Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. 1 and 2.

1 is a block diagram showing a communication terminal having a caller identification function according to an embodiment of the present invention.

Referring to FIG. 1, first, a communication terminal having a caller identification function according to an embodiment of the present invention is connected to a public communication network 1 to transmit / receive a data signal including caller identification information (hereinafter referred to as “first data”). The transmitter / receiver 5, the controller 7 connected to the transmitter / receiver 5, the storage unit 9 connected to the controller, the controller 7 and the receiver 5 And a port portion 13 connected to the switch portion 11 and to the external first terminals 15 to N-th terminal 21. The transmitting / receiving unit 5 has a function of receiving a data signal transmitted through the public communication network 1, and a transmitting function for transmitting the data signal of the receiving side to the transmitting side. In addition, the transmitting / receiving unit 5 transmits information from which the first data is known among the data signals transmitted from the transmitting side to the control unit 7 through a predetermined bus line. The storage unit 9 is composed of a system program for driving the communication terminal 3 and a plurality of memories for storing caller identification information set by the user of the communication terminal 3. Here, the calling party identification information is stored in the first and second memories included in the storage unit 9. The first memory stores calling party identification information (hereinafter referred to as "second data") for inhibiting access of a particular calling party in response to the inhibit mode, and the second memory corresponds to the prohibited mode in response to the selective access mode. Calling party identification information (hereinafter referred to as "third data") for allowing access from other calling parties except the calling party is stored. In addition, the second and third data stored in the first and second memories are set by a user of each of the first to Nth terminals 15 to 21. In addition, the memory device 9 may update the second and third data stored in the first and second memories by the controller 7 from time to time by each user of the first to Nth terminals 15 to 21. It is connected with the control part 7 by the bidirectional bus line so that it may be. The control unit 7 sequentially searches the first memory and the second memory built in the storage unit 9 and transmits the second and third data stored in the first and second memories and the transmission / reception unit 5. The first data is searched and compared, and a predetermined control signal is transmitted to the switch unit 11. The switch unit 11 is controlled by a control signal transmitted from the control unit 7.

In detail, when the data signal including the first data is transmitted to the transmitter / receiver 5, the controller 7 first searches for the second data stored in the first memory of the memory device 9 to transmit / receive the receiver. Compare with the calling party identification information sent to (5). At this time, if any one of the first data and the second data transmitted to the transmitting / receiving unit 5 is the same, the control unit 7 immediately sets the blocking mode so that the switch unit 11 connects to the calling party. To block. On the other hand, if any one of the second data stored in the first memory is different from the first data, the control unit 7 sets the bypass mode to maintain the connection with the calling party and to the second memory. Retrieve the stored third data. Here, if any one of the third data stored in the second memory is the same as the first data, the control unit 7 and the terminal of the first terminal to the N-th terminal (15 to 21) associated with the corresponding data; The control unit 11 transmits a predetermined control signal to the switching unit 11 so that the calling party is connected. The switching unit 11 is controlled by a control signal transmitted from the control unit 7 so that any one of the first to Nth terminals 15 to 21 connected to the port unit 13 is connected to the transmitting / receiving unit 5. Select to be connected to the calling party connected through the public telecommunication network (1). The port portion 13 is connected to the first to Nth terminals 15 to 21 through a port. In addition, the port 13 and the first to N-th terminals 15 to 21 are interconnected by bidirectional bus lines to exchange voice data signals with each other.

The driving characteristics of the communication terminal having the caller identification function configured as described above will be described in detail with reference to the flowchart shown in FIG. 2.

First, when the communication terminal having the caller identification function transmits the data signal including the first data from the calling party through the public communication network 1, the transmitting / receiving unit 5 receives the first data transmitted together with the ring tone ( S1). The control unit 7 loads the first data received by the transmitting / receiving unit 5 and simultaneously searches for the second and third data stored in the first memory and the second memory of the storage unit 9. In addition, the control unit 7 compares the first data loaded from the transmitting / receiving unit 5 with the first and second data stored in the second memory and the first memory of the storage device unit 9 (S2). At this time, the control unit 7 preferentially searches for the second data stored in the first memory of the first and second memories of the storage unit 9. Here, if the first data is the same as the second data stored in the first memory, the controller 7 sets a blocking mode to block the caller's connection, otherwise sets the bypass mode to maintain the caller's connection and In addition, the third data stored in the second memory is sequentially searched (S3, S4, and S5). At this time, if any one of the third data stored in the sequentially searched second memory is the same as the first data, the control unit 7 is the same as the first data of the first terminal to the N-th terminal (15 to 21) The control unit 11 transmits a predetermined control signal to the switch unit 11 so that the terminal related to the data and the calling party are connected. Subsequently, the switch unit 11 transmits a predetermined ring tone so that any one of the first terminals to the N-th terminals 15 to 21 and the calling party are connected by the control signal transmitted from the controller 7. Transmit to any one of the terminals 15 to 21 (S6, S7). In contrast, if the calling party number is not the same as any of the second and third data stored in the first and second memories of the storage unit 9, the calling party is connected to the main terminal. Here, the main terminal is set to any one of the first terminal to the N-th terminal 15 to 21.

As an example, when the calling party having the call number of 111-1111 transmits a ring tone to the receiving party, the control unit 7 stores a memory in which the call number to be blocked is stored among the data stored in the storage unit 9. Search first. At this time, if the call number having 111-1111 is stored in the memory in which the call number to be blocked is stored, the control unit 7 immediately blocks the connection with the calling party. On the contrary, when the call number having 111-1111 is not stored in the memory in which the call number to be blocked is stored, the user of the first to Nth terminals 15 to 21 sequentially searches for the stored data memory. . At this time, if a call number having 111-1111 is stored in the data memory set and stored by the user of the second terminal 17, the control unit 7 controls a predetermined control signal such that the second terminal 17 is connected to the calling party. To the switch unit 11. In addition, the switch unit 11 sets a line to be connected to the second terminal 17 and the caller by the control signal of the controller 7. Further, when the control unit 7 searches the data memory of the storage unit 9, when the call number corresponding to the calling party number 111-1111 is not found among the data stored in the data memory, the first condition is unconditionally first. A predetermined control signal is transmitted to the switch unit 11 so that the terminal set as the main terminal among the terminals to N-th terminals 15 to 21 and the calling party are connected.

Then, the main terminal user connects with the calling party connected to the main terminal, and then sets whether to store the calling party's call number in the first and second memories of the storage unit 9 (S9). If the call number of the calling party connected to the main terminal is rejected, it is stored in the first memory, otherwise it is stored in the second memory (S10, S11, S12).

As described above, when the external calling party requests a connection to the receiving party, the receiving party detects the calling party's call number included in the data transmitted from the calling party to the receiving party. Here, the caller's call number and the predetermined data stored in the receiver's communication terminal are compared with the detected caller's call number to automatically disconnect the caller's connection or automatically connect to a plurality of sub-terminals connected to the receiver's communication terminal by extension.

As described above, a communication terminal having a caller identification function according to an embodiment of the present invention may block an unwanted caller's access at the receiver. In addition, the calling party can automatically connect with the desired recipient. This saves talk time and protects the privacy of others from others.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
