Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for displaying a caller's name on a telephone terminal.

In the conventional method, when a call arrives, a ringing signal activates the telephone's bell circuit, and the bell rings to notify the user of the incoming call. The called party does not know who the caller is until he/she becomes aware of the incoming call, picks up the receiver, and speaks with the other party. Therefore, the called party is inconvenienced in that he cannot select which calls he wants to receive and which calls he does not want to receive.

In order to eliminate this inconvenience,
As shown in Publication No. 504 and Japanese Unexamined Patent Publication No. 54-132105, telephone devices that transmit their own telephone number when making a call and display the telephone number or name of the other party when receiving a call, or those that are registered in advance. Telephone devices have been proposed that allow incoming calls only to certain callers.

On the other hand, telephone devices have functions such as speed dialing and one-touch dialing, and require a memory to store telephone numbers corresponding to these functions.

However, conventionally, phone number registration for speed dialing or one-touch dialing and number registration for displaying caller ID require separate memories and input operations, which is uneconomical and inconvenient for users. There is a problem that.

SUMMARY OF THE INVENTION An object of the present invention is to provide a caller name display terminal device which is economical and has improved serviceability without the above-mentioned conventional problems.

To this end, the present invention provides a storage means for storing a plurality of sets of telephone numbers and names corresponding to the telephone numbers;
input means for storing a telephone number and a name corresponding to the telephone number in the storage means by specifying an address; A method for checking a telephone number and displaying a corresponding name if a match is made, and a means for displaying a corresponding name in a call state.
and means for reading out the telephone number stored in the storage means based on the designation of the address input corresponding to the name stored in the storage means and sending it to the exchange side.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

FIG. 1 shows the transmission and reception of signals according to the present invention, and FIG. 2 is a diagram showing one embodiment of the terminal device according to the present invention.

First, in FIG. 1, when the calling party goes off-hook, a calling signal 1 is sent to the calling exchange via the AB line loop. The originating exchange sends a dial tone 2 to the calling party in a known manner, and the calling party sends the destination telephone number 3. The originating exchange selects an outgoing route from the telephone number 3, activates the destination exchange, and after transmitting the called party's telephone number 4, transmits the calling party's telephone number 5 using a known method such as a public fax network. The receiving side exchange selects a called telephone terminal from the called party's telephone number 4 and sends a paging signal 6 to the called telephone terminal, and also sends the calling party's telephone number 7 as a combination of multi-frequency signals. After that, if the incoming telephone terminal responds, response signals 8, 9 are sent.
and enter into a call with voices 10 and 11.

Next, the operation of the receiving telephone terminal after transmitting the calling party's telephone number 7 will be explained with reference to FIG.

FIG. 2 shows a part of a telephone terminal according to the present invention in which the present invention is implemented. In the figure, a memory 23 is used to store a combination of a telephone number and a name. Assuming that the number of characters is m, the memory required to store one combination is l=4×n+6×m bits.

Therefore, if the number of telephone numbers to be stored is k, then the memory 23 is a memory of k words x l bits, and n=
10, m=10, and k=50, the memory is 50 words x 100 bits. When registering in the memory 23, a signal comes to the write lead 29 and the selector 2
2 transmits information on the addressing lead 31 to the selector output 32. First, specify the address using the address specification lead 31, and then the telephone number input lead 33.
The telephone number is input into the memory 23 using the name input lead 34, and the corresponding name is input using the name input lead 34.

Through the above procedure, important combinations of telephone numbers and names are registered in the memory 23 in advance. The name can be freely decided by the user, and the user can give the name, nickname, etc. that is easiest for the user to understand.

The calling party's telephone number is sent to the receiving terminal from the receiving exchange via a telephone line 36 in a combination of multiple frequencies. The multi-frequency receiver 14 receives the signal and outputs an output corresponding to the received frequency to the receiver output lead 15. This output is converted into a binary number by the code conversion circuit 16 and stored in the number register 18.
Output 17 of register 18 enters one input of comparison circuit 24. Also, the clock signal of clock 19 enters counter 21 through gate 20. The counter 21 is a counter that can calculate up to the number k of addresses in the memory 23, and its output is input to the address of the memory 23 through the selector 22. Therefore, the memory 23 is sequentially read one address at a time by the clock 19, and the telephone numbers stored in the memory 23 are sequentially read out from the memory telephone number output 27 to the comparison circuit 2.
4 is input to the other input. The comparison circuit 24 compares the numeric register output 17 and the memory telephone number output 27, and when they match, outputs an output signal to the comparison circuit output 28, closes the gate 20 to stop updating the address, and opens the gate 25. Since the name corresponding to the calling party's telephone number is output to the memory name output 26 of the memory 23, this output is input to the character generation circuit 30 through the gate 25. The character generation circuit 30 converts the coded name output 26 into characters and displays them on the display 35 as the calling party's name. In addition, in Fig. 2, 12 is a bell, and 13 is a bell.
is a capacitor.

In this circuit, nothing is displayed when the contents of the memory 23 and the calling party number do not match, but when the output of the comparator circuit 24 does not appear even after the counter 21 has completed one cycle, the output 17 of the numeric register 18 is In addition to the character generation circuit 30, a calling party number can also be displayed. Furthermore, since the memory 23 stores frequently used telephone numbers and can specify addresses, it can also be used in common with the memory for speed dialing. This not only makes it possible to achieve economy by sharing the memory, but also allows telephone number registration to be used both for displaying the caller's name and speed dialing, which has the advantage of requiring only one registration operation.

As explained above, according to the present invention, memory can be shared between number registration for calling party name display and telephone number registration for speed dialing, which is economical and requires only one input operation. This has the advantage of simplifying the user's phone number registration operation and improving serviceability.
