Abstract

PROBLEM TO BE SOLVED: To make the telephone number of a display service easy to see by inserting a symbol for dividing an area code and a local code after a number matched with the area code of a storage means and displaying the telephone number of a caller at a display device. SOLUTION: A control circuit 4 detects the telephone number of the caller by a calling telephone number display service by a telephone number detection circuit 3. In this case, the control circuit 4 compares its own area code stored in a RAM 11 with the head part of the telephone number, and when they match, eliminates time matched number. Then, the control circuit 4 compares the area codes of the whole country or a part stored in the RAM 11 with the head part of the telephone number, and when they match, insects a hyphen after the retrieved area code. Further, the hyphen is inserted before the lower four digits of the telephone number detected by the detection circuit 3 and the control circuit 4 displays the telephone number of the caller for which the hyphen is inserted to two parts between the area code and the local code and between the local code and a subscriber number at the display device 14. Thus, a calling telephone number which is difficult to see at the time of being displayed as received is made easy to see.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a main part of an embodiment of the present invention. (1) is an incoming call detection circuit, and a telephone line (2)
Detect incoming calls from. (3) is a telephone number detection circuit for detecting the telephone number of the caller. To elaborate,
Tested outgoing telephone number display service (pre-communication information notification service) in which the telephone station (subscriber exchange) informs the called party telephone of the telephone number of the caller's telephone (information receiving terminal) in Yokohama, Nagoya and Fukuoka. It is being done. This is a service available to the called party's telephone set connected to the telephone line subscribed to this service and provided with a telephone number receiving function. The telephone number data of the caller is transmitted as a modem signal.

This telephone number is composed of an area code, a city code and a four-digit subscriber number. Even if the calling and called parties have the same area code, the number includes the area code.
Also, there is no data such as a hyphen separating the area code and the city code, and the area code and the last four digits of the subscriber number. The telephone number detection circuit (3) detects this telephone number and outputs it to a control circuit (4) described later.

A line connection circuit (5) closes and opens the telephone line (2). A dial transmission circuit (6) is connected to the telephone line (2) and transmits a dial signal. (7) is a hybrid circuit, which is connected to the telephone line (2) and performs 2-wire to 4-wire conversion. (8)
(9) is a speaker and a microphone of the handset, which are connected to the hybrid circuit (7).

(4) is a control circuit composed of a microprocessor, which controls each section based on a program stored in the ROM (10). (11) is a RAM, which is information necessary for the operation of the control circuit (4), for example, the area code (111) of the telephone line (self) to which the apparatus is connected,
The nationwide or partial area code (111) is stored.
Reference numeral (12) denotes an input means, which includes a ten-key (121) for inputting a telephone number or the like and an area code registration key (122) for registering an area code (111).

The registration of the area code is performed by the area code registration key (12
2) The necessary area code can be input using the numeric keypad (121). However, if the subscriber has subscribed to α-LCR, data including the area code is transmitted from the telephone office by online communication at the time of subscription, and this data is transmitted about 5 to 6 times a year.
Updated regularly. The area code included in this data may be used as the registered area code.

(13) is a speaker for outputting sound. (14) is a liquid crystal display device for displaying a telephone number and the like. (15) is a voice synthesis circuit, which generates a voice signal specified by the control circuit (4).

The operation of the embodiment in the above configuration will be described. FIG. 2 is a flowchart showing the operation of the control circuit (4).

The control circuit (4) detects the telephone number of the caller according to the calling telephone number display service by the telephone number detection circuit (3) (S1). This telephone number is added with the area code even if the calling and called parties have the same area code, and the area code and the city code, and the area code and the last four digits There is no data for distinguishing subscriber numbers.

Therefore, first, the control circuit (4)
The own area code stored in (11) is compared with the head of the telephone number (S2), and if they match, the matched number is deleted (S3). Thus, if the calling and called parties have the same area code, the area code that does not need to be displayed (does not require dialing) can be deleted.

Next, the control circuit (4) compares the nationwide or part of the area code stored in the RAM (11) with the head of the telephone number (S2). A hyphen is inserted later (S3). As described above, even if the caller and the called party have the same area code, the telephone number of the caller transmitted from the calling telephone number display service includes the area code. Therefore, usually, the area code can be detected. In this way, a hyphen can be inserted between the area code and the local code.

Next, a hyphen is inserted before the last four digits of the telephone number detected by the telephone number detection circuit (3) (S).
4). Then, the control circuit (4) displays on the display device (14) the telephone numbers of the callers having hyphens in two places between the area code and the local code, and between the local code and the subscriber code. Let it. Further, the control circuit (4) changes the hyphen to "no" voice and causes the telephone number to be uttered from the speaker (13).

Thus, the telephone apparatus of the present invention adds the area code even if the calling and called parties have the same area code, and also sets the area code and the local area code. For phone numbers that do not contain data that distinguishes between the area code and the last four digits of the subscriber number, the area code that does not need to be displayed can be deleted, or the area code, the city code, and the four digits Can be inserted to determine the subscriber number.

At present, many mobile phones and PHS terminals are on sale. A recognition number (for example, 080 for a mobile phone, 0 for a PHS)
50) is added. A symbol such as a hyphen can be inserted in correspondence with the identification number corresponding to the area code.

[0022]

As described above, according to the present invention, it is possible to make it easy to see the telephone number of the outgoing telephone number display service which is hard to see if it is received and displayed.
