Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call transfer system that allows calls to arrive at subscriber terminals registered in advance when the called subscriber is absent.

For various communication services, for example, when a transfer is made to a bank or the like, a computer center may automatically notify the subscriber terminal to which the transfer was made.

It is also conceivable to provide information provision services from subscriber terminals that have an automatic calling function.

When providing information from a computer center as such a system, the configuration shown in FIG. 1 is known.

In the figure, 1 is a computer center, 2 is a network control device with an automatic calling function, 3 and 3' are exchange terminal stations, 4.5 is an office, 6 is a subscriber terminal, 7 is a facsimile terminal, and 8 9 is a subscriber terminal, 9 is a facsimile terminal, and 10 is a voice response device added to the network control device 2.

The network control device 2 is provided to automatically make a call from the computer center 1 to the subscriber terminal 6.8, and when the network control device 2 receives a request for a call from the computer center 1 to, for example, the subscriber terminal 6. Then, the network control device 2 sends the subscriber number of the subscriber terminal 6 to the switching terminal station 3 and calls the subscriber terminal 6 via the switching terminal stations 3 and 3' by well-known switching connection control.
In response to the response from the subscriber terminal 6, the network control device 2 sends the information from the computer center 1 to the facsimile terminal 7, or converts the information from the computer center 1 into voice using the voice response device 10 and transmits it to the subscriber terminal 6. do.

However, for example, when the subscriber of the subscriber terminal 6 is away from the office 4 and moves to the office 5, when a call request is made to the subscriber terminal 6 from the computer center 1, the network control device 2 The subscriber number of the subscriber terminal 6 is sent to the switching terminal office 3 to call the subscriber terminal 6, but if the subscriber terminal does not respond for a certain period of time, the call is made by assuming that the subscriber is absent. had been stopped.

For this reason, subscribers who are often absent due to business negotiations, etc., have the disadvantage of not being able to receive prompt information.

Furthermore, even if a terminal such as a facsimile machine that can automatically receive calls is installed, the subscriber cannot obtain information unless he returns to the place where the terminal that can automatically receive calls is installed. The disadvantage was that information could not be provided promptly.

The present invention improves the above-mentioned drawbacks, and its purpose is to allow information to be transferred in response to a request from a called subscriber so that information can be provided to the subscriber quickly.

Examples will be described in detail below.

FIG. 2 is a block diagram of an embodiment of the present invention, in which 11 is a line corresponding section, 12 is a control section, 13 is a line connection section, 14 is a changeover switch consisting of a gate circuit, etc., and 15 is a pushbutton.

When the user is absent, it is necessary to stop the automatic call receiving function of the facsimile terminal 7.

Also, if the forwarding service information is "02" and there is no response when calling the registered forwarding destination subscriber number,
It is also possible to make the call again to the called subscriber terminal instructed by the computer center 1.

Also, if two or more forwarding destination subscriber numbers are registered, re-calling should be performed in the order in which they were registered, and the operation is the same as when there is only one forwarding destination subscriber number registered. It can be done.

Further, when registering the transfer destination subscriber number, a date and time or time designation can be added so that the information can be provided at the designated date and time.

As explained above, the present invention allows a subscriber terminal such as a computer center having an automatic call function to transmit a transfer destination subscriber number, transfer service information, and the transfer service information to a subscriber terminal such as a computer center having an automatic calling function based on a request from an arbitrary subscriber terminal. An information storage unit is provided for registering forwarding information including the subscriber number of the terminal, and when the subscriber terminal having the automatic calling function makes a call, the receiving subscriber terminal refers to the information storage unit and registers the forwarding information. In this case, the arbitrary subscriber terminal makes a call to the registered subscriber terminal based on the forwarding information, so information from a computer center, etc., is not provided to general subscriber terminals, for example. If applied to such cases, there is an advantage that information etc. can be quickly received even at a moving destination, and there is also an advantage that a call completion rate is improved.
