Abstract

PURPOSE:To automatic transfer an incoming call during absence to a near telephone set in presence by providing an automatic presence detecting circuit to automatically detect the presence and absence of the presence in a telephone set which is set to a private exchange or a key telephone system. CONSTITUTION:When the user of a telephone set 1 goes to absent, absence information are sent to an automatic presence detecting circuit 6, for which a sensor 5 is driven. After a constant time passes, the circuit 6 activates an automatic call originating circuit 7 and the circuit 7 activates a calling circuit 8. Then, the absence information are sent to a CPU11. After the whole recovery of the telephone set 1 is controlled by reception confirming information from the CPU11, the CPU11 itself is recovered as well. When a call is incoming from a general subscriber through a general exchange station 13 to the telephone set 1, this call is informed of the CPU11. When the CPU11 confirms that the telephone set 1 is in absence, the incoming call is connected to a telephone set 9 after the idle condition of the near telephone set 9 is confirmed. The release the absence after the user of the telephone set 1 returns to the seat is also executed samely as a registration method when the user is absent.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention automatically detects whether or not a person is present on a telephone set installed in a private branch exchange or key telephone device, and when an incoming call is received while the person is absent. This invention relates to an incoming call control method based on automatic presence detection, which automatically transfers calls to nearby telephones.

(Prior art) Conventionally, in order to process this type of incoming call while the person is absent, the person must enter registration/cancellation information 1 for call forwarding in advance from the telephone while the person is present, and certain operations must be performed. There was a need.

(The line layer where the invention is about to be decided) Therefore, it is troublesome to enter the information to register or cancel the absence from the telephone in advance, and if you forget to register or cancel the absence, it causes trouble to the people around you. There were some drawbacks.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an incoming call control system that uses automatic presence detection to automatically transfer a call to a telephone set near the incoming call pipe without having to manipulate the presence or absence of a person's presence.

(Title A - Means for Determining Tiles) In order to achieve the above object, the incoming call control method by automatic presence detection according to the present invention comprises a telephone set installed in a private branch exchange or a key telephone device with a light emitting element such as an infrared ray. If the person handling the telephone cannot detect the presence for a certain period of time, it is determined that the telephone is absent, and the absence information is sent to the private branch exchange or key telephone device, and the telephone is connected to the private branch exchange or key telephone device. If there is an incoming call to the phone, the device will respond! *It consists of transferring the incoming call to a telephone installed near the telephone.

(Example> The present invention will be described in more detail below with reference to one drawing.

FIG. 1 is an external view of a telephone equipped with a telephone for automatic presence detection according to the present invention. FIG. 2 is a block diagram showing an embodiment of the incoming call control method using automatic presence detection according to the present invention.

When the user of the telephone 1 is absent, the sensor 2 comprised of a light emitting element such as an infrared ray provided in the IA telephone is activated and sends absence information to the automatic presence detection circuit 6. After receiving the information from the sensor 5, the automatic presence detection port S@6 detects that the person is absent after a certain period of time (for example, 30 minutes) has elapsed, and immediately captures and activates the automatic transmission circuit 7.

It drives the automatic call circuit 7 company call circuit 8 and connects the central processing control unit (CPU) via the switching network IUi.
) 11, activates it, and transmits the absence information of telephone L.

According to the reception confirmation information from the central processing control unit 11, 51! After controlling the recovery of the entire phone L, it also recovers itself.

When a general subscriber (not shown) receives a call to the telephone l via the general switching center 13i, the ePUll is notified of the incoming call to the telephone l via the train of the single office trunk (COT) 12 and the switching network 10.

When ePtJll recognizes that telephone 1 is absent (1-1), it connects to telephone 9 via the above-mentioned general subscriber's incoming call 2COT 12-switching network ltl after confirming the status of nearby telephone 9. , the communication train between the general subscriber and the telephone set 9 is completed.

Further, deletion of the absentee list after the user of the telephone 1 returns to the office is performed in the same manner as the registration method when the user is absent.

(Effects of the Invention) As explained above, the present invention provides a telephone installed in a private branch exchange or a key telephone device with an automatic presence detection circuit for automatically detecting presence or absence of presence. V automatically forwarded the incoming call to a nearby occupied telephone.
This has the effect of automatically enabling the absentee dismissal operation after returning home.
