The central control unit 8 reads the position of the mobile station 3a from the position information storage unit 7, and transmits a call signal of the mobile station 3a to the corresponding base station (base station 6b in this example) via the control line. To instruct. The mobile station 3a receives the calling signal from the position station 6b, rings the bell, and notifies the subscriber of the incoming call. When the subscriber goes off-hook, the telephone line is connected. If the subscriber does not want to accept the incoming call, the incoming call rejection mode can be set to reject the incoming call and prevent the bell from ringing.

[0007]

However, in the above-mentioned conventional indoor radiotelephone device, it is not known where the subscribers of the mobile station are. Therefore, for example, during an important discussion in a conference room, an incoming call bell is generated. It will interfere with the ringing conference. You can prevent this if you have set the incoming call rejection mode, but it is troublesome to set each time, and because of that setting,
There was a problem that emergency calls could not be received.

The present invention solves the above problems, and when a caller calls a mobile station subscriber, the location information of the mobile station subscriber is output to the caller and used as a contact content to determine whether or not to make the call. The purpose of the present invention is to provide a local wireless telephone device which can be selected by a calling party according to the request.

[0009]

In order to achieve the above object, the present invention registers a plurality of base stations including a position information detecting section for detecting the position of a mobile station and the current position of the own station in the base station. Position information registration unit, a plurality of mobile stations including a position information output unit that outputs the position information of the partner station based on the information from the base station, and position information storage that stores the position information of the mobile station output from the base station And a location information notification unit for transmitting location information to the mobile station via the base station, centrally controlling the base station, and having a central control unit connectable to an external telephone network.
