Abstract

PURPOSE:To prevent mis-registration by registering an abbreviation dial number while it is confirmed that there is no error in called party dial numbers by just preceding dialing. CONSTITUTION:A telephone communication system consists of a subscriber exchange 20 and telephone sets 1, 2 accommodated in the subscriber exchange 20. The exchange 20 consists of a central controller 21, a channel controller 22, a channel network 23, a subscriber data file 24, an outgoing register trunk 25, an intra-office trunk 26 and a signal tone trunk 27. Just after it is confirmed that there is no error in the called party dial number in actual dialing, a registration command code and an abbreviated dial number are inputted. Thus, mis- registration is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a speed dial number registration system used in a telephone communication system.

(Prior Art) In telephone communication systems, a speed dial number registration method is adopted in order to eliminate the trouble of dialing a called party number with a large number of digits each time a call is made.

Conventionally, to register a speed dial number, the subscriber connects with a dial tone and then enters a predetermined registration command code (“0” + r%J),
This is done by sequentially inputting [speed dial number] and [called party dial number].

(Problems to be Solved by the Invention) In the conventional speed-dial number registration method described above, the speed-dial number and the dialed number of the called party are inputted consecutively, which increases the total number of input digits and is time-consuming. In addition, there is a problem that erroneous registration is likely to occur.

(Means for Solving the Problems) The speed dial number registration method according to the present invention includes means for storing the dialed number of the called party at the time of the last call in the subscriber data file of the calling party; means for receiving a registration command code and a speed dial number from a user, and registering the dialed number of the called party at the time of the last call being stored in the subscriber data file of the calling party while associating the registration command code and the speed dial number with the speed dial number; Prepared for exchange.

Therefore, according to the registration method of the present invention, the registration command code and the speed dial number are input immediately after it is confirmed that there is no error in the dialed number of the called party through the actual calling operation, so there are no problems with the conventional method. This effectively prevents erroneous registration.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Embodiment) FIG. 2 is a block diagram showing the configuration of a telephone communication system to which a speed dial number registration method according to an embodiment of the present invention is applied. 20 is a subscriber exchange, and 1 and 2 are the subscriber exchanges. This is a telephone housed in 20. The exchange 20 is
Central control device 21, communication path control device 22, communication path network 23
．． Subscriber data file 24, originating register trunk 2
5. It is equipped with an internal trunk 26 and a signal tone trunk 27.

The subscriber data file 24 includes, as shown in FIG.
A registration area for the dialed number of the called party at the time of the last call and an abbreviated dial number registration area are reserved in association with the subscriber addresses xxx, yyy of the telephone 1.2, etc.

When the user of telephone 1 registers a speed dial number for telephone 2, he first makes a call to telephone 2 and makes a conversation to confirm that the dialed number of the called party is correct.
By terminating the call, the exchange 20 is temporarily restored. After this call is completed, the subscriber address corresponding to telephone 1 in the subscriber data file 24 (in the example of FIG. 3, r
xxx"), and the telephone number of telephone 2 ([123-45 in the example in Fig.
67J) is saved as the dialed number of the called party at the time of the previous call. Thereafter, the user of telephone 1 instructs registration of abbreviated number dialing by calling again.

When the central control unit 21 detects the call from the telephone 1, it proceeds to the first step 11 in the flowchart of FIG. + "■"), and if it is not this registration command code, the process proceeds to normal call processing. In this example, since the registration command code has been input, the central controller 21 follows this registration command code with the speed dial number (ro in the example of FIG. 3) held in the calling register trunk 25.
2J) in an empty entry in the speed dial number registration area in the subscriber data file 24 of this caller.

Thereafter, the central control device 21 proceeds to step 13 and stores the subscriber data file 24 of the telephone 1 that issued this registration command.
Read the called party's dial number "123-4567J" at the time of the most recent call from the called party's dial number storage area in the above-mentioned speed dial number registration area, and register it in association with the speed dial number "02" already registered in the speed dial number registration area. . In the final step 14, the central control unit 21 causes the signal tone trunk 27 to send out a predetermined signal tone to notify the user of the telephone of the completion of registration, thereby completing the registration process.

The above example has been exemplified in which the exchange has a function of storing the dialed number of the called party at the time of the most recent call for purposes such as billing processing. However, for exchanges that do not have such a storage function due to differences in billing processing, such a storage function may be added for the speed dial number registration process.

(Effects of the Invention) As explained in detail above, the speed dial number registration method according to the present invention includes means for saving the dialed number of the called party at the time of the last call in the subscriber data file of the calling party; The exchange is equipped with a means for registering the stored dialed number of the called party in a subscriber data file of the calling party while associating it with the speed dialing number upon receiving a registration command and a speed dial number from the calling party. Therefore, the speed dial number is registered after it has been confirmed that there is no error in the dialed number of the called party due to the previous calling operation, which effectively eliminates the problem of erroneous registration with the conventional method. It has the effect of being prevented.
