First, when the telephone user picks up the handset 40, the CPU 100 detects the off-hook (S1), and the CPU 100 closes the telephone line via the DC closing circuit 20 (S2) and displays the message. The device 80 is cleared (S3), and a standby state for the telephone number display operation is entered. Next, if there is a dial operation (S4), the CPU 1
Internal or external telephone number memory 101 in 00
The dial numbers are sequentially stored (S5), and then a telephone number display operation described in detail below is started (S6).
The operation of sequentially storing dial numbers in the telephone number memory 101 (S5) and the operation of displaying telephone numbers (S6) are performed substantially in parallel. On the other hand, when transmitting a dial signal based on the dial operation to the telephone line, the CPU 100 detects a dial tone as necessary, and after detecting the dial tone (S7), corresponds to the number sequentially read from the telephone number memory 101. Send dial signal (S

When the call ends and the telephone user returns the handset 40 to the telephone, an on-hook operation is detected (S
11) Disconnect and release the telephone line (S12), and display 8
At 0, calendar display and clock display are performed (S14), and the process returns to step S1 to be in a standby state.

FIG. 3 is a flowchart showing a detailed control operation of the CPU 100 relating to the telephone number display operation of step S6 in the processing flow of FIG.

First, the dial numbers are sequentially stored in the telephone number memory 101, and at the same time, the CPU 100 sequentially reads out the stored telephone numbers from the head number (S20).
The comparison with the international communication carrier identification number in the telephone number table 90 is started (S21). If the identification number matches one of the international communication carrier identification numbers, since the next number is a country code, the next number of the international communication carrier identification number stored in the telephone number memory 101 and the telephone number table 90 Is compared with the country code (S22). If any one of the country codes matches, if the telephone number table 90 has the number of digits of the area code, the local area code, and the subscriber number for each country code, the comparison is performed sequentially in the same manner as the country code. Perform collation (S23-
S25). The telephone number is displayed on the display 80 by inserting a space, a delimiter, or the like for each of the number divisions in which the number of digits matches the number of digits (S26).

In the comparison and collation with the international telecommunications carrier identification number (S21), if there is no match, it is determined that the communication is domestic communication. Therefore, the comparison and collation with the domestic telecommunications carrier identification number is performed (S27). If the ID number matches one of the identification numbers of the domestic telecommunications carriers, the next number is the area code, so that the domestic telecommunications carrier identification number at the head of the stored telephone number is excluded from the comparison target (S31). ), A comparison is made between the number following the domestic communication carrier identification number stored in the telephone number memory 101 and the area code of Japan in the telephone number table 90 (S28). Here, if any one of the area codes matches, if the telephone number table 90 has the number of digits of the local area number and the subscriber number for each area code, it is sequentially compared and collated similarly to the area code. Is performed (S29 to S30). A telephone number is displayed on the display 80 by inserting a space, a delimiter, or the like into each of the number sections where the number of digits matches the number of digits (S2).
6).

In the comparison and collation with the domestic telecommunications carrier identification number (S27), if there is no match, it is determined that the NTT line is used, and the number from the top of the stored telephone number is converted to the outside of Japan. The comparison and collation are sequentially performed from the station number (S28 to S30). A telephone number is displayed on the display 80 by inserting a space, a delimiter, or the like into each of the number sections where the number of digits matches the number of digits (S26).

In the comparison and collation between the area code and the area code of Japan (S28-S29), if there is no match, an identification number and storage for selecting an NW (network) service possessed by each communication carrier are stored. A comparison is made with the number from the beginning of the entered telephone number (S32). If there is a break in the number following the identification number for each NW service,
The comparison and collation are sequentially performed with the telephone number table 90 for each service identification number (S33), and the telephone number is displayed on the display 80 by inserting a space, a delimiter, or the like for each number division in which the number of digits matches the number of digits. (S26).

In the series of comparison and collation between the telephone number memory 101 and the telephone number table 90 in the above operation (S23 to S23).
S25, S28-S30, S32-S33), when it is determined that they do not match, a normal continuous display is performed (S3).
4).

The operation of the above embodiment according to FIGS. 1 to 3 will be described in more detail with respect to a domestic number. Domestic telephone numbers are roughly classified into the following four types.

(1) Domestic numbering plan: area code + local number + subscriber number (2) International numbering plan: international identification number + country code + destination number (3) Interconnection numbering plan: relay operator identification number + Service identification code + subscriber number + various information (4) NW service identification number plan: 0 ABC system number and 1
XY System Number and Function Button (X, #) System Number FIG. 4 shows a configuration example of domestic numbers generally represented by 0A to J. For example, the unit charge area of Tokyo (M
message Area: MA) is an area code where the first digit A is “3” except for the first “0”, and the next four digits B
E is a local station number, and the last four digits FJ are subscriber numbers.
In the MA of Yokohama, the first two digits AB are the area code of "45", and the next three digits CE are the local area codes. In any case, except for the first "0", the domestic number has a maximum of nine digits.

The international identification number of the international number is "00X
Begins with the (Y) ", the relay operator identification number of interconnect numbering plan begins with" 00Z ₁ Z ₂ ". Note that it is X ≠ Z _1.

FIG. 5 shows an example of a telephone number table for only domestic numbers, which is composed of area code data and delimiter position data representing format information. For example, when the area code of the telephone number type is “03” in Tokyo, the delimiter insertion position is next to the second digit of “03” and “0”.
This is the sixth digit following the 4-digit local office code following "3".
When the area code is Yokohama “045”, the delimiter insertion position is next to the third digit of “045” and next to the sixth digit including the three-digit local area code following “045”.

FIG. 6 shows that the CPU 100 in FIG.
3 shows a detailed control flow for displaying a telephone number based on the telephone number table of FIG.

First, the dial number input by the dial key operation is temporarily read into the telephone number memory 101.
Next, the dialed number is compared with the area code of the telephone number table 90 based on the domestic number plan stored in advance, and if there is a matching area code, the corresponding delimiter position data is obtained. Displays the dialed number with a separator.

Specifically, the case of FIG. 5 in which the telephone number table targets only domestic numbers will be described. First, when the caller inputs "03" and a dial number (S
A1) The dial number “03” is temporarily stored in the telephone number memory (SA2). Next, the dial number within the first five digits including "03" is compared with the area code in the telephone number table (SA3). In step SA3, if there is a matching area code, the delimiter position data is obtained from the corresponding item number in the telephone number table, and the telephone number is displayed (SA4). In this case, “2 and 6” are obtained as segment position data from the item number 1 with the area code “03”. Therefore, the first two digits of the dialed telephone number
A delimiter such as "-" is inserted after the digit and the sixth digit from the beginning and displayed.

With this control, when the sender inputs "033509XXXX", "03-3" is displayed when "033" is input, and "0335" is displayed.
09 ”is displayed, and“ 03-3509- ”is displayed. When dialing is completed, the display“ 03-3509-X ”that is usually used in the telephone number book is displayed.
XXX "can be performed. If there is no matching area code, all digits of the input dial number are continuously displayed as before (SA5). Similarly, if the dial number input is “06”, “2 and 5” are obtained as the delimiter position data, and if the dial number input is “045”, “3 and 6” are obtained as the delimiter position data. .

Next, a case where the telephone number table covers the international numbering plan, the interconnection numbering plan, and the NW service identification numbering plan will be described. FIG. 7 shows a telephone number plan type table in which the number plans roughly classified into four types are classified in more detail, and is composed of dial number input head number data and telephone number plan type data. For example, if only the first digit is “0” and not “0A0”, it can be identified that the call is a toll call based on the domestic numbering plan. The first digit is "0", "1", "X",
If it is not any of "#", it can be identified that the call originates in the city based on the domestic numbering plan. The first two digits are "0
In the case of "0", the numbers in the third and fourth digits can identify the long-distance interconnection numbering plan or the international numbering plan. If the first three digits are “0A0”, use a mobile phone or PH
It can be identified that S is the mobile system interconnection number plan. "0" at the beginning, excluding some area codes
The system, “XXY” system, “#XY” system, and “#ABCD” system can be identified as NW service identification number plans.

FIG. 8 shows that the CPU 100 in FIG.
FIG. 6 shows in detail a control flow for displaying a telephone number based on the telephone number plan type table of FIG. 5 and the telephone number table for each number plan type as shown in FIG.

First, the dial number input by the dial key operation is temporarily read into the telephone number memory (SB)
1, SB2). Next, the head number is compared with the head number of the telephone number plan type table stored in advance (SB3). Therefore, if there is a matching head number, it is compared with a telephone number table stored in advance for each telephone number plan type (SB4), the corresponding delimiter position data is obtained, and the data is delimited to the input dial number. Is displayed (SB5). If there is no corresponding telephone number in the telephone number type table or the telephone number table for each type, all digits of the input dial number are continuously displayed as before (SA5).

More specifically, a case where the telephone number table covers an international numbering plan, an interconnection numbering plan, and a NW service identification numbering plan will be described. First, when the dialer inputs "033" and a dial number (SB1),
The dial number “033” is temporarily stored in the telephone number memory (SB2). Next, a comparison is made between the dial number within the first five digits including "03" and the first number in the telephone number plan type table (SB3). In step SB3, since the matching head number is item number 1 in the telephone number plan type table, it is compared with the domestic number plan type telephone number table according to the control flow of FIG. 6 (S
B4). In step SB4, if there is a matching area code, the delimiter position data is obtained from the corresponding item number in the telephone number table shown in FIG. 5, and the telephone number with the delimiter is displayed (SB5).

Further, the telephone number table contains not only telephone number types and telephone numbers for each type, but also names of prefectures and municipalities in area codes and city numbers of domestic numbering plans, and names of international numbers in types of international numbering plans. Telecommunications carrier name, country name, interconnection number plan type, long-distance relay carrier name, and NW service identification number plan type are also stored with NW service name. In addition to the number display, the name of the destination area, the name of the carrier used, and the NW
It is also possible to display telephone number additional information such as a service name.

FIG. 9 shows an example of a telephone number table based on a domestic communication plan. The telephone number table shown in FIG. 5 is obtained by adding area name data to the area code data and delimiter position data. is there. Also, if the telephone number table is stored in advance not to the local area code but to the specific subscriber name, in addition to the telephone number display with the delimiter inserted, the destination area name and the subscriber name can be displayed. It can also be displayed. FIG. 10 is an example of the display display of the telephone, showing a case where the area is Tokyo “03” and the subscriber name is “Nakashima”.

The above description of operation shows the dialing number display at the time of calling, but when displaying the calling side telephone number using the "calling telephone number notification service" provided by the telecommunications carrier, the switching side is used. Are sequentially stored in the telephone number memory 101 and the operations in steps S20 to S34 shown in the flowchart of FIG. It is possible to display the telephone number on the display 80 by inserting a character or a separator.

Further, since the telecommunications carrier identification number, country code, area code, local area code, subscriber number, NW service identification number and the like are not unique and universal, the telephone number table 90 is required for flexible correspondence. Is desirably rewritten. In this case, the tone detection / generation circuit 70 is provided with a modem for data communication, or a modem for receiving the telephone number of the calling side is shared. CP for number table 90
It is desirable to download and rewrite as needed via U100.

Further, if all telephone number types are covered as the telephone numbers stored in the telephone number table, it can be clearly understood that there is no matching number at all, and that it is an erroneous dial immediately after the end of the dialing operation. Therefore, it is possible to provide a function for prompting a redial operation. Also, in the case where the area code matches, but the number of digits below the local area code does not match, it can be easily recognized that an erroneous dial has occurred. Conversely, if the telephone number stored in the telephone number table is limited to domestic general calls, if an international call is made or a special NW service is used, all digits of the telephone number will be displayed continuously as in the past. However, the effect of the present invention is not lost.
Also, the usefulness of the phone number display is that it uses the “Caller ID Notification Service” to make outgoing calls when you do not know who called you at all, compared to displaying the phone number operated by the user himself. It is considered that displaying the local telephone number is higher. Therefore, if you want to limit the display of phone numbers in a legible manner to incoming calls for domestic general calls,
If only the area code is stored in the telephone number table, the last four digits are always the subscriber number, so it is possible to classify the local area code and the subscriber number naturally, and the memory capacity of the telephone number table is small. I can do it.

In the case of a telephone having no telephone number table rewriting means, when a change or addition occurs in an area code or a local code, all digits are continuously displayed only for the specific number. Yes, the effects of the present invention are not lost even for station numbers that have not been changed. Therefore, even if the telephone number table cannot be downloaded via the network, if the application target is narrowed down to the area code or the local area code, the area code is not frequently changed or added.
It would be practically sufficient for the user to be able to register a change or addition of a new station number in the telephone number table by operating the telephone as necessary.

Although the circuit block of FIG. 1 shows a case of a telephone connected to an analog telephone line, it can be applied to a telephone connected to a digital line.

[0055]

According to the present invention, blanks and delimiters can be inserted for each type of telephone number in the process of displaying the other party's telephone number when making or receiving a telephone call. Has a recognizable effect. In particular, when making a call, if the same button is pressed twice or digits are erroneously dropped, there is also an effect that the telephone can automatically determine an erroneous dial before the other party answers.
