Abstract

PURPOSE:To easily confirm a location of a cordless telephone set of an opposite party when an extension call is implemented between cordless telephone sets. CONSTITUTION:Cordless telephone set connectors BS1-BSn form radio zones RZ1-RZn. Cordless telephone sets T1-Tm use a cordless telephone set connector whose radio wave reception state is best among the cordless telephone set connectors BS1-BSn. In the case of extension call among the cordless telephone sets T1-Tm, an extension processing section 21 refers to a position registration information storage section 31 in which the information of a radio zone releating to the cordless telephone set connector used by each of the cordless telephone sets T1-Tm to acquire the radio zone corresponding to the cordless telephone set connector used by the caller and the called cordless telephone sets and sends the acquired caller and called radio zones to the called and caller cordless telephone sets as data to be displayed on the display device of the called and caller cordless telephone sets.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone device, and more particularly to a cordless telephone connecting device each forming a wireless zone, and one having the best reception of radio waves from each cordless telephone connecting device. The present invention relates to a cordless telephone device having a plurality of cordless telephones that are selectively used and a main device that controls connection between the cordless telephone and a telephone line and connection between cordless telephones.

[0002]

2. Description of the Related Art Conventionally, a cordless telephone device of this type is provided with an indicator on each cordless telephone, and when an extension call is made between cordless telephones, like a wired telephone,
There is one in which the extension number of the calling side cordless telephone is displayed on the display of the called side cordless telephone.

[0003]

With the above configuration, the callee can confirm which cordless telephone the call is from based on the display on the display.

By the way, since a wired telephone does not move, it is possible to indicate the location of the other party by displaying the extension number of the other party as described above. However, in the case of a cordless telephone, the extension number can be moved. There is a problem that the location of the other party cannot be indicated only by displaying.

An object of the present invention is to provide a cordless telephone device which can indicate the location of the other party when making an extension call between cordless telephones.

[0006]

A location registration information storage unit for registering the location registration information storage unit, and the extension processing unit refers to the location registration information storage unit when the extension cordless telephones are used by the calling and called cordless telephones. The location information corresponding to the cordless telephone connecting device, and the obtained location information corresponding to the cordless telephone of the calling side is acquired by the called side. As data to be displayed on the display of the cordless telephone, transmitted to the cordless telephone of the called side, and the acquired position information corresponding to the cordless telephone of the called side is displayed on the display of the cordless telephone of the calling side. It is transmitted to the cordless telephone on the calling side.

[0007]

[Function] Each cordless telephone selects and uses the cordless telephone connecting device having the best reception of radio waves among the cordless telephone connecting devices, and each cordless telephone is used in the location registration information storage section. Location information corresponding to the cordless telephone connection device is registered.

When an extension call is made between cordless telephones, the extension processing unit refers to the position registration information storage unit to obtain the position information corresponding to the cordless telephone connecting device used by the cordless telephones of the calling side and the called side. .

Then, the acquired position information corresponding to the cordless telephone of the calling side is transmitted to the cordless telephone of the called side as data to be displayed on the display of the cordless telephone of the called side, and the obtained cordless telephone of the called side is acquired. The corresponding position information is transmitted to the calling cordless telephone as data to be displayed on the display of the calling cordless telephone.
