[Industrial application field]

TECHNICAL FIELD The present invention relates to an automatic dial search method for a telephone terminal device having a display function of a dialed number.

Recent advances in semiconductors have diversified the functions of telephones, and it has become possible to add various functions in addition to the original telephone call function. In particular, by incorporating a CPU and memory into a chip, it has become possible to store the calling subscriber's calling dial number and display it on the display.

This dialed number display function is added to confirm the dialed number of the other party, and this display function is used to provide an automatic dialing search method for the caller, which is different from the conventional speed dialing method. It is something.

[Conventional technology]

FIG. 4 shows a schematic configuration diagram of a conventional telephone terminal device. In the figure, 1 is a display, 2 is a CPU, 3 is a memory, 4 is a numeric keypad, 5 is a line control unit, 6 is a talking unit, 7 is a handset, 8 is a push button, 9 is a subscriber line, and 10 is a telephone terminal device. shows.

When the calling subscriber lifts up the handset 7 and presses the central office line key on the pusher i port 8, a call is made from the telephone terminal device 10 to the central office exchange, and the caller hears the tone from the central office and selects the other party's number. If you input this from the numeric keypad 4, you can call the other party's telephone if the other party is not busy.

The above is a method for making a call using a normal telephone terminal device, but if the telephone number has a long number of digits or is a number that is called frequently, it is possible to register an abbreviated number and make a call using the abbreviated dial number.

In the conventional speed dialing method, the caller raises the handset 7, presses the central office line key on push button 8, captures the subscriber line 9, confirms the dial tone, then presses the short key on push button 8, and dials the registered abbreviation. When a number is input using the numeric keypad 4, the other party's number registered in the memory 3 is sent to the subscriber line 9. To register a speed dial number, the subscriber lifts up the handset 7, presses the speed key of push button 8, inputs the registered speed dial number using the numeric keypad 4, presses the speed key again and inputs the number of the other party to be registered using the numeric keypad 4, By pressing the # button on the numeric keypad 4 to hear the service end tone, and then putting down the handset 7, the registration of the other party's number as an abbreviated number is completed. For example, the registration abbreviation number is 01 and the registered partner number is 04477711.
11, registration of the abbreviated number is completed by inputting (abbreviated) 01 (abbreviated) 0447771111#.

A schematic explanatory diagram of the space table of the memory 3 is shown in FIG.

In the figure, the dial number of data 0447771111 is stored in the dial number memory space of address XX01, and the next registration number, for example, 0452113 is stored in address XX02.
599 dial numbers are stored as data. Since dial numbers are subsequently registered corresponding to the address of the abbreviated number in the same manner, the other party's dial number corresponding to the abbreviated number can be extracted from the memory.

[Problem to be solved by the invention]

In the conventional system described above, speed dial numbers can be used with or without a display, but it is necessary for the caller to register the other party's telephone number as a speed dial number in advance. An object of the present invention is to automatically register a history of past dialed numbers in a memory without registering the numbers, thereby shortening and transmitting dialed numbers from the second time onward.

[Means to solve the problem]

FIG. 1 shows a basic configuration diagram of a telephone terminal device according to the present invention. In the figure, l is a display that displays the dialed number; 3
1 is a memory that stores the history of outgoing dial numbers, 4 is a numeric keypad for inputting outgoing dial numbers, 5 is a line control unit that connects to the subscriber line, and 2 is a CPU that connects to each of the above devices and processes and controls each function. show. Note that ■ to ■ indicate connection routes. The CPU 2 also includes a number recording means 14 for storing outgoing dial numbers in the memory 3 in descending order of numbers, a number searching means 15 for searching the stored numbers in descending order of number history, and a display 1 for displaying the retrieved numbers. Number display means 1 to be displayed on
6, and the memory 3 is equipped with a dial [function] When the subscriber hears the dial tone and inputs the outgoing dial number from the numeric keypad 4, the CPU 2 detects the press of the numeric key in the ■ route, and the dial number is stored in the memory 3 by the route. Store. At this time, the number recording means 1 of the CPU 2 is stored in the memory 3.
4, the dialed numbers are stored in the dialed number memory space 11 in ascending order of the number, and the dialing history floor indicating the order in which the dialed numbers were dialed is inputted into the dialing history floor memory space 12 of the memory 3, and is stored in the address correspondence memory space 13. Address correspondence numbers for number searches will be manually created.

Next, when the subscriber presses the numeric keypad 4 in order to dial the calling number, the CPU 2 searches the address-corresponding memory space 13 on the memory 3 using the number search means 15 from the top digits, and displays the 1. Display notification is performed in the route. If the dialed number is displayed sequentially from the top digit and the number to be dialed matches the displayed number, when the subscriber presses the call key, the displayed dialed number is sent to the CPU 2. From there, the call is automatically made to the subscriber's line via the line control unit 5 according to the route.

FIG. 2 shows the display state of the display according to one embodiment. Second
In the figure, ■ is the display state of the display when the originating subscriber presses 0.4.4. ■ means that the calling subscriber is next 7
When pressed, the CPU searches the memory and displays the other party's dialed number 0447771111. 3 shows the display state of the display when the originating subscriber confirms that the search dial and the other party's dial number match and presses the call button.

FIG. 3 shows a schematic explanatory diagram of a memory according to an embodiment of the present invention, in which FIG. 3(a) shows a memory space (table) and FIG.
shows the memory creation procedure.

Three memory spaces (tables) are prepared in the memory, 1
1 is a dial number memory space, 12 is a dial history memory space, and 13 is an address corresponding memory space. In the dial number memory space 11, the numbers are determined from the first digit and arranged in descending order according to the address. Numbers are assigned to the dial history memory space 12 in the order of dialing and assigned to the same address.

In order to scan dial history numbers, the address correspondence memory space 13 stores addresses containing numbers in the history starting from the smallest address.

The memory creation procedure is as follows: (1) Assume that the number dialed by the calling subscriber is 0452113599. ■ Compare the number in the dial number memory space 11 from the top digit and store it in the third memory space. That is, it corresponds to address area 0002H. ■ Enter the dial history number in the dial history memory space 12 in the same memory at address 0002 T-1. That is, if the history number is the second, enter 002.

■Address area 0002 in address corresponding memory space 13
Stores H's address number 0002.

The dial search procedure is to dial the number you want to dial from 03-56.
9-1245, the first, second, etc. of the number dialed from the newest one in the address memory space I3, that is, the one with the larger address digit.
and displays the first searched item with the same number. In other words, if 062321→11 is the latest dial, search for this number first with 035, then 045211.
Search for 3599, then search for 034781234,
Next, search for 098781234, then search for 0356912
45, it is detected that this number matches 035, and it is displayed on the display 1 at the same time. By the above operation, it is possible to sequentially compare the most recently pressed dial number with the currently pressed number. Therefore, the display 1 can display the match between the search dial number and the dial number.

〔Effect of the invention〕

According to the present invention, there is no need for the user of the telephone to register the dialed number, and the CPU inside the telephone inputs the history of the dialed number into the memory and searches for it, so that the user registers the dialed number. Since you can obtain the effect of shortening the dialing time without having to do this, it is possible to automatically register the dialed numbers of frequently called parties.
