Description

[Detailed Description of the Invention] [Outline] The telephone number information before the number change and the telephone number information after the number change are sent from the exchange side to the subscriber side using a digital subscriber line. The subscriber side receives this information and automatically corrects the telephone number of the subscriber whose number is being changed, which is recorded in the automatic dial number recording area.

[Industrial application field]

The present invention relates to a renumbering notification service of an electronic exchange system and an autodial service of a subscriber terminal, and in particular, when the autodial number recorded in the terminal has a renumbered number, auto dialing is performed without manual operation. The present invention relates to an automatic dial number automatic correction method that can correct a number after it has been renumbered.

[Conventional technology]

When the conventional number change notification service determines that the called subscriber number (destination number) received on the exchange side is the number being changed, it connects the calling subscriber terminal to the talkie trunk and It was just a notification of the number change with a number talkie or tone.

This kind of renumbering notification is the same regardless of whether the call is made by a dial operation of a general subscriber or in the case of automatic call using an auto dial device.

[Problems to be solved by the invention]

Therefore, when making a call using the auto-dial device on the calling subscriber terminal side, the auto-dial number before the number change must be corrected to the number after the number change by the manual operation to know the number change by the conventional number change notification method. There was a problem that it had to be.

An object of the present invention is to make it possible to automatically correct the auto-dial number recorded in the terminal to the number after the number change when the number is being changed when the number is transmitted from the terminal. It is to improve the service.

[Means for solving problems]

The above problem is caused by a switching system in which the exchange 1 and the subscriber terminal 2 having an automatic dialing function are connected by a digital subscriber line as shown in FIG. The receiving / recognizing means 2c for recognizing the presence / absence of a number change by receiving digital information sent from the digital subscriber line 1 and the received telephone number before the number change are stored in the auto dial number storage area 2b. The exchange 1 is added with the collating means 2d for collating with the existing auto dial number.
When it is determined that the telephone number of the other terminal 3 is being changed when the subscriber terminal 2 makes a call to the other terminal 3, the number before the number change is performed via the control channel of the digital subscriber line. The telephone number and the telephone number after the number change are transmitted as digital information to the subscriber terminal 2, and the subscriber terminal 2 receives and recognizes the digital information.
When the digital information is received by 2c and it is recognized that the digital information is renumbering information, the means for collating the telephone number of the other terminal 3 stored in the autodial number storage area 2b with the received and recognized telephone number before the number change. If the two numbers match each other according to 2d, the problem is solved by rewriting the number before the number change of the other terminal 3 stored in the auto dial number storage area 2b to the number after the number change. . Note that 2e is an auto dial transmission unit.

[Action]

According to the present invention, in the number change notification service of the exchange system, the calling subscriber terminal is notified of the telephone number information before the number change and the telephone number information after the number change by using the digitalized subscriber line. Then, the calling subscriber terminal receives the above-mentioned renumbering information sent from the exchange, compares the telephone number information before the renumbering with the already recorded autodial number, and matches the autodial number. Since the auto-dial number is automatically corrected by rewriting the number to the telephone number information after the number change, the effect that the customer service is significantly improved is produced.
