JPS63217864A - Absence transfer release system - Google Patents

Abstract

PURPOSE:To prevent an incoming call from being transferred to an absence transfer destination if a called party comes back as scheduled by setting the release time of absence transfer so as to release the transfer automatically when the designated time comes even if the setting of absence transfer is forgotten. CONSTITUTION:A called subscriber, in the event of setting absence transfer, depresses a special key from an extension of its own seat and inputs an absence transfer release designation time. A central processing unit 2 analyzes the inputted absence transfer release designation data and writes a bit S1 representing the absence transfer setting state and a bit S2 representing the absence transfer release time setting state to an absence transfer control memory section 7 of a main storage memory 3 corresponding to the extension number together with an absence transfer time release designation time TM. The central processing unit 2 compares the present time from the time counter 6 with the time TM at a prescribed time interval and applies the absence transfer release processing when they are coincident to clear the absence transfer control memory section 7 corresponding to the extension number in the main storage memory 3.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a call forwarding cancellation method in an automatic private branch exchange, and in particular, the called party specifies the call forwarding setting and the canceling time, and This invention relates to an automatic call forwarding cancellation method that automatically cancels call forwarding.

(Prior art) Conventionally, in this type of call forwarding system, once call forwarding is set, the call forwarding status continues until the call forwarding is cancelled. Every time I returned, I had to cancel the call forwarding.

5. (Problem that the invention attempts to solve) In the conventional call forwarding method described above, if you set up call forwarding and then forget about it, incoming calls that come to the extension that is being forwarded forever will be automatically forwarded. Since the calls are forwarded to the forwarding destination extension, even if the person who leaves the seat returns from the forwarding destination, the calls are not received at his/her own extension, and important calls cannot be received. In addition, it is extremely troublesome to cancel call forwarding immediately after returning to your desk, and there are many cases where you leave the call in the same state and then cancel call forwarding only after realizing it, which makes it easier to contact the caller. There is a drawback that it does not work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a call forwarding canceling method that automatically cancels the call forwarding when a specified arbitrary time period elapses after setting the call forwarding.

(Means for Solving the Problems) The call forwarding cancellation method of the present invention includes a means for the called party to set a designated time for canceling call forwarding, and a means for the called party to set a designated time for canceling call forwarding. and means for automatically canceling the transfer. More specifically, the present invention provides a storage means for storing a designated time for canceling call forwarding set by a called subscriber, and a time for counting the time from the time when the designated time for canceling call forwarding of the called subscriber is set. The apparatus includes a counting means, and a means for comparing the current time counted by the time counting means and the designated time for canceling missed call forwarding and automatically canceling missed call forwarding when they match.

(Example) Next, the present invention will be explained by way of example with reference to the drawings.

FIG. 1 is a block diagram of a call forwarding cancellation device in an automatic private branch exchange in the case of implementing the present invention, and FIG.
FIG. 3 is a diagram schematically showing the memory contents of a missed transfer control memory section in the figure. In FIG. 1, it is assumed that a called subscriber's extension telephone 4 and a calling subscriber's extension telephone 5 are connected via a communication path switch 1. In FIG. The called subscriber who does not control the call path switch 1 presses a special key on the extension telephone at his/her desk when setting the call forwarding, and then inputs the designated time for canceling the call forwarding. In addition, if you want to skip the above operations (pressing a special key, inputting the designated time to cancel call forwarding) after setting up call forwarding,
Call forwarding cannot be canceled by specifying a time. The central processing unit 2 analyzes the input missed call forwarding cancellation designation data, and stores a bit S1 indicating the missed call forwarding setting state and a missed call forwarding release time setting state in the missed call forwarding control memory section 7 of the main memory 3 corresponding to the extension number. A bit S2 indicating this is written together with the missed transfer cancellation designated time TM.

The central processing unit 2 reads the current time from the time counting device 6 and the missed transfer cancellation designated time TM in the memory at a fixed time period.
When the values match, the missed call forwarding cancellation process is performed and the missed call forwarding control memory section 7 corresponding to the extension number in the main memory 3 is cleared.

(Effects of the Invention) As explained above, according to the present invention, by setting the time to cancel call forwarding, even if you forget that you have set call forwarding, it will be automatically canceled when the initially specified time comes. Therefore, if the called subscriber returns from the missed call forwarding destination to his own extension as scheduled, there is no worry that the incoming call will be forwarded to the missed forwarding destination, and he can receive and respond to his own extension.
