Abstract

PURPOSE:To transfer an incoming call to the transfer destination registered in advance and to prevent the increase of potential incompleted calls when an incoming call comes in a private radio extension moved outside the radiowave range. CONSTITUTION:When a private radio extension 13 moves outside the radiowave range, a connector 8 detects it and makes notification through a line controller 5 to a central control unit 2. The central control unit 2 eliminates the connector 8 being the position information from the position register memory corresponding to a private radio extension 13 of a storage device 3. In this state, when an incoming call comes to the private radio extension 13 which is cancelling the position register, the central control unit 2 reads out the transfer destination information from the transfer destination memory corresponding to the private radio extension 13 of the storage device 3 and transfers the incoming call to the transfer destination since no position information is registered in the position register memory corresponding to the private radio extension 13.

[0003]

In the conventional call transfer of the in-house wireless extension, when the in-house wireless extension moves out of the radio range and becomes in the call disabled state, the call to the in-premises wireless extension in the call disabled state is received. Could not be transferred to other wireless extensions for the premises, wired extensions for the premises, relay stations, talkie devices, and outside lines, and the ringing tone would continue to be sent until the caller abandoned the call, which is potentially There was a problem that the number of completed calls increased.

An object of the present invention is not to call an internal wireless extension when a call arrives at the internal wireless extension that has moved out of the radio wave range, not through the connection device that accommodates the internal wireless extension. , And to provide a wireless extension call transfer system for private use, which directly transfers an incoming call to a pre-registered transfer destination and avoids an increase in potential incomplete calls.

[0005]

The indoor wireless extension call transfer system of the present invention comprises a plurality of movable indoor wireless extension lines.
In a private branch wireless extension call transfer method in a private branch exchange that accommodates a plurality of connection devices capable of accommodating a plurality of connection devices within the radio range capable of connecting the private wireless extension, the private wireless extension of each of the connection devices The premises radio is provided with a memory for registering position information indicating whether or not the premises radio range is located and transfer destination information indicating a transfer destination when the premises radio extension moves outside the sphere, corresponding to the premises radio extension. When the wireless extension moves out of the radio wave area and becomes in a call disabled state, the connection device accommodating the private wireless extension detects this movement and notifies the central controller provided in the private branch exchange, Delete the corresponding registered location information from the memory, and read the corresponding transfer destination information from the memory when a call arrives at the on-premise wireless extension whose location registration is being deleted.
The incoming call is transferred to a corresponding transfer destination.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The premises electronic exchange includes a time division switch 41, and line control devices 4 to 5 which control connection devices 6 to 9 which are connected to the premises wireless extension lines 10 to 15 and can be accommodated in the respective radio ranges 16 to 19. Which are centrally controlled by the central controller 2 according to the information in the storage device 3. FIG. 2 shows an example of the memory configuration of the internal wireless extension memory 20 of the storage device 3 used in the present invention. The internal wireless extension memory 20 is composed of extension number corresponding blocks 21-1 to 21-n of the wireless extension accommodated in the private branch exchange, and the wireless extension number corresponding blocks 21-1 to 21-n are located in the location registration information storage area 22. -1 to 22-n and transfer information storage areas 23-1 to 23-n. It is assumed that the wireless extension number corresponding block 21-3 is a block corresponding to the wireless extension number of the indoor wireless extension 13.

The indoor radio extension 13 is now accommodated in the radio range 18 of the connection device 8, and the connection device 8 detects this and goes through the line control device 5 to send a position registration request to the central control device 2. Tell. In response to the position registration request, the central control unit 2 stores the position registration information storage area 22 of the wireless extension number corresponding block 21-3 corresponding to the extension number of the internal extension 13 of the internal extension memory 20 in the storage device 3. To -3,
The information of the connection device 8 that accommodates the indoor radio extension 13 in its radio range 18 is written and the location is registered. In addition, the transfer information storage area 23 of the wireless extension number corresponding block 21-3
-3 is for registering transfer destination information in advance when moving out of the radio range by operating buttons such as a maintenance terminal or a relay stand or special number operations from a wired or wireless extension for the premises. The transfer information storage area 23- 3 is a wireless extension for the premises 1 as transfer destination information.
It is assumed that the wireless extension number of 0 is registered.

In this state, when an incoming call arrives at the internal wireless extension 13, the central control unit 2 refers to the wireless extension number corresponding block 21-3 of the internal wireless extension memory 20 in the storage unit 3 to find the location registration information. After identifying from the storage area 22-3 that the connecting device accommodating the internal wireless extension 13 is the connecting device 8, the connecting device 8 is instructed to call the internal wireless extension 13 via the line control device 5. .

Next, the indoor radio extension 13 moves to move out of all the radio areas 16 to 19 including the radio area 18,
It is assumed that it is out of the radio range. The connection device 8 detects the same as at the time of position registration and issues a position deletion request to the central controller 2
Tell to. The central controller 2 responds to the position deletion request,
The contents of the location registration information storage area 22-3 of the wireless extension number corresponding block 21-3 are erased and the location registration is deleted.

In this state, when an incoming call arrives at the indoor radio extension 13, the central control unit 2 determines the location registration information storage area 2
2-3 is searched, but since the contents of the location registration information storage area 22-3 have been erased, next, the transfer information storage area 2
3-3, the wireless extension number of the indoor wireless extension 10 is read as the transfer destination information. Further, the central control unit 2 reads the contents of the location registration information storage area 22-1 of the block 21-1 corresponding to the non-extension number corresponding to the wireless extension number of the in-premises wireless extension 10. Since the information of the connection device 6 is stored in the location registration information storage area 22-1, the central control device 2 instructs the connection device 6 to call the internal wireless extension 10 via the line control device 4. .

[0012] Further, the wireless extension 13 for the premises is in the radio range 16
When the user moves to any one of -19, it is housed in the connection device within the radio range again and the same location registration processing as described above is executed, so that the incoming call to the indoor wireless extension 13 is not transferred and is used for the indoor area. Call the wireless extension 13. It goes without saying that the same operation is performed even when the transfer destination is a wired extension for a premises, a relay stand, a talkie device, and an outside line.

[0013]

As described above, according to the present invention, when the indoor radio extension moves out of the radio wave range and the call cannot be made, an incoming call to the indoor radio extension is made to another indoor radio extension or the indoor wire extension. Since it is possible to transfer to a relay stand, a talkie device, and an outside line, it is possible to avoid the problem that the ringing tone is continuously output until the caller gives up the call halfway and the number of incomplete calls potentially increases. Have.
