Abstract

PURPOSE:To prevent the disabled incoming call due to forget of releasing operation by adding a designation means for registration release time to a variable absence transfer registration means so as to release variable absence registration automatically after a designated time elapses. CONSTITUTION:A caption ENo is an address representing an accommodated location of a registering subscriber (e.g., subscriber No 2000) and a caption DNo is a number representing a transfer destination subscriber (e.g., subscriber No 2001) in a variable absence destination registration table 51. Then an absence monitor program started periodically is provided in a memory 30 and for every said program is started by a processor 20, '1' is decremented from the time till the release or a time TCo registered in an release time registration table 60. When the value of TCo reaches '0' as the result, the registration of the variable absence destination registration table 51 and a terminal control management table 52 is released. Since the registration of the variable absence transfer is released automatically at a designated time or time interval as above, the forget of releasing operation is prevented.

Description

[Detailed Description of the Invention] [Summary] Regarding the variable missed forwarding registration control method in exchanges using the storage program control method, the purpose of this invention is to prevent inability to receive calls due to forgetting to cancel the variable missed forwarding registration. The registration means includes means for specifying a deregistration time in response to an instruction from the terminal, and the processor is configured to count the deregistration time and cancel the registration in the variable absence transfer registration means after the elapse of the time. do.

[Industrial application field]

The present invention relates to a variable missed call forwarding registration control system in a storage program control type exchange.

In the variable call forwarding registration control system, when a person moves from place to place for a conference or the like, a service is provided in which incoming calls are registered in advance to be forwarded to a terminal such as a telephone at the place of the move.

In this case, when the user returns from the destination to the original location, the incoming call must be made to the terminal located at the location of the light.

[Conventional technology]

A variable call forwarding function has been used for a long time. That is, in the conventional system, when telephone A performs a variable call forwarding registration operation and sets the forwarding destination to B, calls that arrive at A thereafter are automatically forwarded to B.

To cancel the registration, the user performed the registration cancellation operation from the phone iA. In this way, conventional variable call forwarding registration cancellation was performed when the user returned to the original location.

[Problem that the invention seeks to solve]

In the conventional method described above, if you do not perform the deregistration operation even if you return to the original location, all incoming calls to phone A at the location of the light will be transferred to phone B, and calls to phone A will no longer be able to be received. There is a problem with that.

SUMMARY OF THE INVENTION In view of the problems in the prior art described above, an object of the present invention is to prevent inability to receive calls due to forgetting to cancel variable call forwarding registration.

[Means for solving problems]

FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 1 is a network, 2 is a processor, 3 is a memory, and 4 is a terminal. A storage program control exchange is shown in which the terminals 4 are connected via the network under the control of the processor 2.

The memory (3) is provided with a variable absence transfer registration means (5) for registering the terminal number of the transfer destination for an incoming call in accordance with an instruction from the terminal 4. The variable absence transfer registration means (5) includes means (6) for specifying a registration cancellation time in response to an instruction from the terminal 4.

The processor (2) counts the deregistration time and deregisters the registration in the variable absence transfer registration means (5) after the elapse of the deregistration time.

[For production]

The registration is automatically canceled after the specified cancellation time has passed, so even if the user forgets to cancel the variable call forwarding registration, the call will be received at the corresponding light location when the user returns from the destination. be able to.

〔Example〕

FIG. 2 is a block diagram showing a telephone switching system to which an embodiment of the present invention is applied.

In the configuration shown in FIG. 2, when registering variable call forwarding from the telephone (Tel A) 41 to the telephone (Tel B) 42, conventionally, the telephone set 41 simply sends the variable call forwarding special number and the forwarding destination number (the number of the telephone set 42). This was done by dialing. In the embodiment of the present invention, in addition to the above operations, registration of the release time or the time until release is added. That is, the variable call forwarding registration cancellation time (or time until cancellation) dials the child axis destination number (the number of the telephone 42). The cancellation time and transfer destination number may be reversed.

FIG. 3 is a diagram illustrating a portion of the contents of memory 30 according to an embodiment of the invention.

In the figure, a memory 30 (see FIG. 2) includes a variable absentee address registration table 51, a terminal control management table 52, and a release time registration table 60. In the variable absentee registration table 51, E
No. is an address indicating the accommodation location of a registered optical subscriber (for example, subscriber No. 2000), and DNo is a number of a transfer destination subscriber (for example, subscriber No. 2001). These are registered by dialing the variable call forwarding special number and forwarding destination number through the above operation. In the terminal control management table 52, ABS is a flag indicating whether variable absentee forwarding is being registered.
=1 indicates registration is in progress, and ABS=0 indicates registration cancellation. In the cancellation time registration table 60, TCo is the time or cancellation time from setting to cancellation of call forwarding registration, and is registered by dialing in the above operation.

Further, STP is a stopper and determines whether or not to execute the absence release monitoring program.

Then, the above-mentioned absence monitoring program that is periodically activated is provided in the memory 30, and each time the program is activated by the processor 20, 1 is subtracted from the time until cancellation or time TCo registered in the cancellation time registration table 60. do. As a result, when the TCoO value becomes 0, the registration in the variable absent light registration table 51 and the terminal control management table 52 is canceled. As described above, since the registration of variable absentee forwarding is automatically canceled at the specified time or time, it is possible to prevent forgetting to cancel the registration.

FIG. 4 is a flowchart showing the flow of processing from reception of a numeric event to execution of a variable call forwarding registration program according to an embodiment of the present invention.

With reference to the same figure, the case where variable call forwarding registration is performed from the telephone (Tel A) 41 and the call is transferred to the telephone (Tel B) 42 will be further explained.

If you set the variable absence registration special number to 13, register it at 13:00, and cancel it at 15:00, you will receive "13" from the telephone (Tel A) 41.
Dial ゛ + “1500” + “2001”.

The dialed digits determine whether the line processor (LPR)
) 43, the event control program 401 is started, whereby the numeric event is stored in the memory (1"l?!l)
It is stored in the digit storage memory (DSB) in 30.

The digit analysis program 402 is then activated to determine whether to perform the variable call forwarding task.

In the above example, execution of the task is determined by the variable absence special code 13, and then the task execution control program 403 is executed, the variable absence transfer registration program 404 is executed, and the destination subscriber is registered in the variable absence optical registration table 51. Number '20
01' is registered, variable absent transfer registration means ABS=1 is set in the terminal control management table 52, and release time registration table 60 is set.
The time (2 hours or 15:00) is set.

FIG. 5 is a flowchart showing the flow of the absence cancellation monitoring program according to the embodiment of the present invention.

In the same figure, at step 501, the cancellation time registration table 60
It is determined whether there is a registration, and if it is, 1 is subtracted from the release time in step 502, and it is determined in step 503 whether the release time has become O, and if it is 0, the variable absent light registration table 51 and Clear the terminal control management table 52. Next, in step 505, the presence or absence of the stopper STP is detected,
If there is none, repeat steps 501 to 505 above.

Note that instead of replacing the time until cancellation in the cancellation time registration table with the cancellation time, the monitoring program may detect the cancellation timing by checking whether it is the cancellation time.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, by adding a means for specifying the registration cancellation time to the variable absence transfer registration means, the variable absence registration is automatically canceled after the specified time elapses. This can prevent you from not being able to receive calls due to forgetting.

In addition, in the above embodiment, the case of a telephone was explained, but
Similar effects can be achieved with other terminals.
