Abstract

PURPOSE:To call a portable radio telephone terminal equipment belonging to a designated zone by designating a zone number. CONSTITUTION:Radio telephone base station interfaces RI1-RIn controlling radio telephone base stations RS1-RSn are accommodated in a master set 1 and a master control section 2 controls the interfaces. When portable radio telephone terminal equipments RT1-RTm enter zones 1-n covered by the radio telephone base stations RS1-RSn, each radio telephone base station recognizes a portable radio telephone terminal equipment. When the operation to designate a zone is implemented from an accommodated terminal equipment, the main control section 2 calls all portable radio telephone terminals under the control of the radio telephone base station in the designated zone to establish the communication between one portable radio telephone terminal replying the call and the terminal equipment implementing the call operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone device,
In particular, the present invention relates to a button telephone device that accommodates a portable wireless telephone terminal of a multi-zone portable wireless telephone system.

[0002]

2. Description of the Related Art Conventionally, this type of button telephone device is constructed so that when calling a portable wireless telephone terminal from the button telephone terminal, a call can be made without being aware of the location of the portable wireless telephone terminal. The zone to which the wireless telephone terminal belongs can be determined in the main device, but the zone cannot be called from the button telephone terminal by specifying the (location).

[0003]

In the above-mentioned conventional button telephone device, when calling from the button telephone terminal to the portable wireless telephone terminal, a call can be made without being aware of the location of the portable wireless telephone terminal. Since the mobile wireless telephone terminal cannot be called by specifying the zone (location) from the telephone terminal, it is not possible to specify the location and call the mobile wireless telephone terminal moving to that location. There are drawbacks.

[0004]

A key telephone device of the present invention comprises a main unit for accommodating a plurality of key telephone terminals and a plurality of radio telephone base stations, and covers each zone covered by the radio telephone base stations. In a key telephone device having a function that can be used even when a plurality of mobile radio telephone terminals move, the main device includes a storage unit that stores in advance the numbers of the radio telephone base stations corresponding to the numbers of the plurality of zones. When a terminal accommodated in the main device specifies and calls one of the zones covered by the radiotelephone base station, the portable device belonging to the specified zone is input. It has calling means for calling the wireless telephone terminal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, according to the present embodiment, radio telephone base stations RS1 to RSn in respective zones 1 to n are provided.
And button telephone terminals T1 to Tk with display and main device 1
And the main device 1 has radio telephone base stations RS1 to RS1.
Radio telephone base station interfaces RI1 to RIn that interface with RSn on a one-to-one basis, button telephone terminal interfaces TI1 to TIk that interface with bodan telephone terminal interfaces TI1 to TIk with a display on a one-to-one basis, and radio telephone base stations RS1 to RS1. RSn
The storage unit 4 in which the zone numbers corresponding to the respective numbers are registered in advance, and the main control unit 2 for controlling the entire main device 1
And is configured.

In this embodiment, it is assumed that the radio telephone terminals RT1 to RTm are present in the zones 1 to n, respectively.

Next, the operation of this embodiment will be described.

The main unit 1 includes radio telephone base stations RS1 to R.
Radio telephone base station interfaces RI1 to control Sn
There are RIn and button telephone terminal interfaces TI1 to TIk for controlling the button telephone terminals T1 to Tk, which are controlled by the main controller 2 to the main controller 3.

When the portable radio telephone terminals RT1 to RTm enter zone 1 to zone n covered by the radio telephone base stations RS1 to RSn, each radio telephone base station recognizes the portable radio telephone terminal and communication is performed. It will be possible.

Here, for example, the key telephone terminal Tk accommodated in the main unit 1 designates the zone n covered by the radio telephone base station RSn, and a predetermined specific operation for calling it is performed.

This operation is equivalent to a conventional extension call or extension zone call, and the main control unit 2
Is the extension number designated in advance by this operation, or the number n of the radio telephone base station RSn from the extension zone number is stored in the storage unit 4
Then, all mobile radio telephone terminals under the radio telephone base station RSn are called via the radio telephone base station interface RIn and the radio telephone base station RSn. Among them, a call is established between the first portable radiotelephone terminal that responded first and the key telephone terminal Tk that performed the main calling operation.

[0014]

As described above, according to the present invention, each zone covered by the radiotelephone base station is provided with a plurality of portable radiotelephones provided with the main unit for accommodating the plurality of button telephone terminals and the plurality of radiotelephone base stations. In a key telephone device that has a function that can be used even if the terminal moves, the terminal accommodated in the main device inputs predetermined specific information to call by designating one of the zones covered by the radio telephone base station. When
By having the calling means for calling the mobile wireless telephone terminal belonging to the designated zone, it is possible to call the mobile wireless telephone terminal by designating the place.
