DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a telephone system according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the overall construction of an embodiment apparatus to which the present invention is applied. In FIG.
The telephone system according to this embodiment is a private branch exchange (PB).
X) 1 and a plurality of areas 5-1, 5-2, ... Controlled by the private branch exchange 1.

Here, the private branch exchange 1 includes a station line accommodation circuit 11 for controlling an outside line, a time switch 12 for controlling a line exchange, a wired system extension accommodation circuit 13 for controlling a wired extension telephone such as a fixed telephone, and a radio. The system includes a radio system extension accommodating circuit 14 that controls the main unit of the system and a control unit 15 that controls the entire private branch exchange 1.

Further, in each of the areas 5-1, 5-2, ..., A telephone (fixed telephone) 4 connected to the wired extension accommodation circuit 13 of the private branch exchange 1 and a radio extension accommodation circuit 14 are connected. The base unit (CS) 2 and the mobile phone (PS) 3 connected to the base unit 2 via a wireless line.

Here, the mobile phone (PS) 3 is configured to be movable between the areas 5-1, 5-2, ... And each mobile phone (PS) 3 is located in the area to which it belongs. It is configured to register.

FIG. 2 shows an external configuration of the mobile phone 3 shown in FIG.

The mobile phone 3 shown in FIG. 2 is a small terminal that can be easily carried around, and the receiver 2
0, a display unit 21, an operation unit 22, and a transmitter unit 23.

Here, the display unit 21 is used for displaying a destination number when receiving a call, displaying a transfer destination number during transfer, other status display, and message display.

The operation unit 22 also includes special function keys such as hold, transfer, on-hook and off-hook, in addition to the number keys used when making a call.

By the way, this embodiment has a plurality of areas 5-1, 5-2, ... Controlled by the private branch exchange 1, as shown in FIG.
If there is an incoming call to the mobile phone 3 belonging to 1 and this mobile phone 3 is busy, the incoming call is sent to the same area 5-
It is configured to automatically transfer to a telephone (fixed telephone) 4 located inside 1.

For this reason, the control unit 15 of the private branch exchange 1 has a location registration table 40 of the mobile telephone shown in FIG.
It has an area extension number reference table 50 shown in FIG.

The location registration table 4 of the mobile phone
0, as shown in FIG. 4, a cell phone identification code column 41 in which the identification code of each cell phone is written, and an area number column 4 in which the area number to which the cell phone belongs is written.
2 and a busy identification field 43 indicating whether or not the mobile phone is busy.

And an extension number column 52 in which the extension number of the telephone (fixed telephone) 4 included in the area is written.

Next, in this embodiment, the private branch exchange 1
The processing procedure executed by the control unit 15 will be described with reference to FIG.

In this process, the private branch exchange (PBX)
When there is an incoming call to the mobile phone 1 (step 300), the registration area of the incoming mobile phone 3, that is, the mobile phone 3 to be called is shown in FIG.
Search is performed by referring to 0 (step 310).

Next, it is checked whether or not the mobile phone 3 to be called is busy (step 320). This processing is performed by searching the location registration table 40 of the mobile phone shown in FIG. That is, if "1" is set in the busy identification column 43 corresponding to the mobile phone 3 in the position registration table 40 of the mobile phone shown in FIG. 4, busy is set if "0" is set. Determine not.

When it is determined in step 320 that the mobile phone 3 is not busy, the mobile phone 3
(Step 330), and this process ends.

When it is determined in the process of step 320 that the call is busy, the extension number of the registration area of the mobile phone 3 which has received the call is referred to by referring to the area extension number reference table 50 shown in FIG. Check (step 340).

Then, the incoming call is automatically transferred to the telephone (fixed telephone) 4 of the extension number (step 350),
