Abstract

PURPOSE:To allow any telephone set to transmit a similar abbreviated dial number by registering an abbreviated number and a destination number corresponding thereto on a magnetic card. CONSTITUTION:After a subscriber inserts a magnetic card 22 in the registration with abbreviation, the subscriber dials the abbreviated number in 2 digits and the desitination number in maximum 10 digits next to the abbreviation registration special number ''0*''. The fetched dial number is set on a registration table on a memory in a microcomputer constituting a control section 18. All the abbreviated numbers and the destination numbers corresponding to them on the table are written on the card 22 via a write control section 24 and a write head 26. Further, a destination number corresponding to the dialed abbreviated number is searched out from the storage content of the card 22 when dialing.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention Background of the Speed Dial Technology in Telephone Communications Speed dialing is one of the subscriber services in telephone communications. Speed dialing involves dialing a 3-digit abbreviated number that combines function buttons (*, +) and numeric buttons (0 to 9) instead of dialing the phone number of the other subscriber. It is a service connected to.

Prior Art and Problems In the conventional speed dialing system, a storage device for storing all destination numbers corresponding to speeded numbers is located at the central telephone office, and the storage location ψ is allocated to each subscriber. . Therefore, a speed dial set on a certain telephone can only be used on that phone, and it is impossible to make a call using the same speed dial on another telephone without making the same settings.

Purpose of the Invention Accordingly, the present invention solves the above-mentioned problems of the prior art, and the purpose of the present invention is to provide a speed dial system that allows calls to be made using the same speed dial from any telephone once registered. Our goal is to provide the following.

Structure of the Invention A feature of the present invention that achieves the above-mentioned object is that an abbreviated number and a corresponding destination number are registered on a magnetic card, and the destination number corresponding to the abbreviated number dialed when making a call is transferred to the magnetic card. The aim is to identify all targeted subscribers by searching from the stored contents.

Examples of the invention FIG. 1 shows a schematic configuration of an embodiment of the present invention.

In the figure, a speed dial device is connected to a line 14 via a 10-digit telephone and a 12-digit telephone 10. The speed dialing device 12 includes a telephone keyboard 16 having numeric buttons from 0 to 9 and function buttons such as *, a control section 18 mainly consisting of a microcomputer, a dialing signal sending section 20, and writing information to a magnetic card 22. A controller 24, a write head 26, a controller 28 for reading information from the magnetic card 22, and a read head 30 are provided.
ing.

FIG. 2 shows a control program of a microcomputer provided in the control section 18 of the speed dialing device 12 shown in FIG. 1, and the operation of the dialing device will be explained below using this diagram.

When the power is turned on, execution of this control program starts. In step 40, it is fully detected whether or not the basic card 22 has been inserted into the A-bin card input slot (not shown). If it is not inserted, repeat step 40.

If the magnetic card 22 is inserted into the input slot, step 4
1, it is fully detected whether or not a key-in has been performed from the keyboard 16. The process of step 41 is repeated until key-in is performed. If keyed in,
Proceeding to step 42, it is determined whether the first two-digit dial number keyed in is a special number "0*" representing abbreviated registration. If the abbreviated registration special number is "0*", proceed to steps 43 and 44 and change the numbers following that special number to 1.
Import it with. When performing abbreviated registration, the subscriber first inserts the magnetic card 22 into the input slot, dials "0*", then the two-digit abbreviated number, and then dials the entire 0-digit destination number. In step 44, the end of the dialed number is determined based on whether the input interval is 4 seconds or more (75). Next, in step 45, the received dial number is set in the registration table on the memory in all microcomputers. This allows the next destination number to be stored as a two-digit abbreviated number index on the registration table as shown in FIG. 3. In the next steps 46 and 47, all the abbreviated numbers on the registration table and their corresponding destination numbers are written to the magnetic card 22 via the write control unit 24 and the write head 26. Once all the information on the registration table has been written, the program moves to step 40.
Return to

On the other hand, if it is determined in step 42 that the first two digits of the dial number keyed in are not the abbreviated registration special number "*+", the program proceeds to step 48. Step 48
Then, it is determined whether the keyed-in first digit dial number is the abbreviated calling special number "*". If it is not a shortened calling special number, the process advances to step 48, where an error warning is issued, and then the process returns to step 40. In the case of the short dial special number 6*, the subscriber goes to Stella 7'50 and takes in the two-digit number that is keyed in after the special number.When making a short dial call, the subscriber must immediately insert the entire magnetic card 22 into the card. After inserting it into 1*, dial the desired 2-digit short # number next to 1*”.

Next, the process proceeds to steps 51 and 52, where the read control unit 28
Then, all the short shoes stored in the magnetic card 22 and their corresponding destination numbers are cut and outputted via the read head 30i, In the next step 53, the registration table is searched for an index equal to the Kikufu number that was keyed in this time, and the stored content in that index is determined based on the target number corresponding to the short tane/2@ number. is read out from the g record table.Next, in step 54, the dial signal sending section 2 is fully activated and sends out the read destination number onto the line 14 via the telephone set 1o.Then, the program returns to step 40 again.

As described above, according to the present invention, the abbreviated number and the corresponding destination number are registered on the magnetic card, and the destination number corresponding to the abbreviated number dialed when making a call is sent to the f3EI, L of the magnetic card. , Internal Temperature: Since it is searched and obtained, it is very convenient to register it once on a magnetic card and then send it from the same short dial from the same diary.
