Abstract

PURPOSE:To receive the service of calling-back function at a moving destination anywhere a subscriber moves by executing the designating registration of the automatic call-back from the subscribing station of a distant place via a general telephone line with the subscriber for which the automatic calling-back service is registered to an accumulating type telephone line exchange. CONSTITUTION:Since the subscriber receives the automatic remote calling-back service at the moving destination, a recognizing number 8 is dialed from an arbitrary telephone set 22 and an exchange 3, to which the subscriber originally subscribes, to be allowed the automatic remote calling-back function is called. After that, the subscriber dials a code number 9 of itself from a telephone set 2 by a PB (push button) signal. Next, time information 10 to desire to receive a call-back and a subscriber number 11 of the telephone set 2, which desires to receive the call-back, are dialed from the telephone set 2 to the exchange 3 by the PB signal. The exchange 3 to receive them stores the time information 10 and the subscriber number 11. Thus, even when the subscriber is in the distant place, the automatic calling-back service can be received.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic remote call back service system for a storage type telephone line exchange.

[Prior Art] Conventionally, this type of automatic call-back service has been implemented when a registered subscriber of a storage type exchange is allowed automatic call-back services such as wake-up calls by the exchange. It was only possible to register an automatic call-back time from the telephone and receive an automatic call-back to the telephone from the exchange.

[Problems to be Solved by the Invention] However, in the conventional automatic call-back service described above, the telephone that can receive the automatic call-back service is limited to the registered subscriber's own telephone. Even if the subscriber's exchange allows an automatic call-back function, if the subscriber moves to a remote location far from his or her own telephone, it may not be possible to receive the automatic call-back service. There was a drawback.

[Means for Solving the Problems] The present invention solves the above problems and provides an automatic remote call back service that allows subscribers who have registered for the automatic call back service to receive the automatic call back service even in remote locations. The purpose is to provide a service method.

In order to achieve the above object, the automatic remote call-back service system according to the present invention allows a subscriber who has registered automatic call-back service in a storage type telephone line exchange to call from a subscriber station in a remote location via a general telephone line. The subscriber performs automatic call-back designation registration with the storage-type telephone line exchange to which the subscriber has registered, and the storage-type telephone line exchange connects the subscriber station in a remote location specified by the subscriber to the general telephone line. It automatically calls back at the specified time via the route.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the operating state of automatic call-back registration reception from a remote location according to an embodiment of the present invention, and FIG. 2 is a diagram showing the case where there is no first relay exchange.

That is, FIG. 1 shows a case where the telephone to which the subscriber wants to receive a call does not belong to the exchange to which the subscriber originally subscribed, and FIG. This indicates that the switch belongs to the same exchange.

In FIGS. 1 and 2, a subscriber who has received automatic callback registration moves to a remote location other than the telephone 1 that received the registration. In order to receive the automatic remote callback service at the destination, the subscriber dials the identification number 8 from any telephone 2 and calls the exchange 3 to which he or she has originally subscribed and is permitted to have the automatic remote callback function. In the case of FIG. 1, the exchange 3 is called via the outgoing trunk 5, the telephone line 6, and the incoming trunk 7.

Exchange 3, which has received identification number 8, recognizes that the call is a registration request for automatic remote callback, and sends a response signal back to telephone 2. As a result, a communication path between the telephone set 2 and the exchange 3 is established.

Thereafter, in order to prevent this service function from being used maliciously by others, the subscriber must input his/her personal identification number 9 from the telephone 2.
is dialed using the PB (button button) signal. Exchange 3 receives the PIN number 9 and checks its validity.
If the result is negative, release the call and reject the registration request. - On the other hand, if the PIN number 9 is recognized as valid by the exchange 3, the subscriber then inputs the time information 10 for receiving a call back and the subscriber number 11 of the telephone 2 for receiving a call back to the telephone. From 2, use the PB double signal and dial to exchange 3. The exchange 3 that receives these stores the time information 10 and the subscriber number 11. By the above-described operation, automatic call-back registration acceptance from a remote location is completed. In the case of FIG. 2, the same procedure as in FIG. 1 is performed.

3 and 4 are diagrams showing the operation of automatic callback at a remote location according to this embodiment, and FIGS.
This corresponds to FIG.

In FIGS. 3 and 4, when the time reaches the registered time as described above, the exchange 3 sends the registered telephone number 1
A call is automatically made to telephone number 1 and telephone number 2 is called back. The subscriber who receives and answers the call knows that he or she has been called by the automatic remote call-back service by waiting for the announcement message sent from the exchange 3. The above-described operations complete the remote automatic callback, whereby the subscriber receives a callback at the remote location.

As shown in FIGS. 1 and 3, the function of the present invention is required only for the exchange 3 that requires an automatic remote callback function, and if there is another device between the exchange 3 and the telephone 2. Even if the exchange 4 intervenes, there is no function required of the exchange 4. Further, since the call charges for the automatic callback shown in FIGS. 3 and 4 are charged to the subscriber 1 who subscribes to the exchange 3, there is no problem in terms of billing.

[Effects of the Invention] As explained above, the present invention provides that if a subscriber is allowed a call-back service, the call-back function can be provided at the destination wherever the subscriber moves within the country. This has the effect of making it possible to receive

Note that the present invention can also be used as a wake-up call to call back at a specified time at a remote location.
