FIG. 3 is a diagram showing an example of a conventional high-performance telephone terminal device, and FIG. 4 is a diagram showing an example of a conventional incoming call signal.

In FIG. 3, an analog audio signal output from a telephone transmitter 1 is converted into, for example, an 8-bit digital code by a code/decoder 2, and sent to a subscriber who is digitized via a subscriber line interface 3. The digitally encoded voice signal sent to the vA4 and arriving from the subscriber line 4 is transmitted to the code/decoder 2 via the subscriber line interface section 3, where it is converted into an analog voice signal and sent to the receiver. 5 is input 1・1. Ru.

At the time of an incoming call, the telephone switching network 16 transmits an incoming call signal as shown in FIG. 4 to the incoming telephone terminal via the subscriber line 4. The incoming call signal consists of a control information section for call setup, and the control information section includes an incoming call code tc indicating an incoming call.
and the telephone number on of the calling telephone terminal device. The signal control section 7 extracts the telephone number On from the incoming call signal received via the subscriber line interface section 3, and displays it on the character display section 8 capable of displaying numbers and letters.
The called party is notified of the incoming call in a known manner.

[Problems to be Solved by the Invention] As is clear from the above explanation, in a certain high-performance telephone terminal device, when a call is received, the telephone number of the calling telephone terminal device is It was sent to the display section 8. Therefore, the subscriber had to look up the caller from the displayed telephone number in a telephone directory or the like.

[Means for solving problems]

The problem is that in a telephone terminal device equipped with a means for displaying numbers and characters, a means is provided for identifying the presence or absence of information exchanged between subscribers that is added to an incoming call signal arriving from a telephone exchange network; The problem is solved by the present invention, characterized in that when the means detects the information, the display means displays numbers or characters for identifying the calling party included in the information.

[Effect]

When the originating telephone terminal device transmits a calling signal including the user's name, etc. in the information exchanged between subscribers, the telephone switching network transmits an incoming call signal to the terminating telephone terminal device in response to the calling signal. The information added to the call signal is then added to the call signal and transmitted. The incoming telephone terminal device identifies whether or not information exchanged between subscribers is added to the incoming call signal, and if it is detected that information is added, the user's name, etc. included in the information is is displayed by numerical and character display means. As a result, the user of the receiving terminal device can immediately recognize the user of the calling terminal device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a high-performance telephone terminal device according to an embodiment of the present invention, and FIG. 2 is a diagram showing an incoming call signal according to an embodiment of the present invention.
