A mobile radio telephone apparatus operating in a plurality of zones. The apparatus includes a plurality of communications devices, each assigned respectively to the plurality of zones, for establishing a wireless communications channel with a mobile terminal located within one of the assigned zones; a plurality of management devices, each assigned respectively to the plurality of zones, for radioing to a mobile terminal moving from a zone outside of the assigned zones to one of the assigned zones and for emitting position information indicating the assigned zone in which the mobile terminal enters; a register device for registering the position information; a first memory device for storing the position information; a second memory device for preregistering at least one of the plurality of zones; a process selecting device for inhibiting the management device assigned to the zone preregistered in the second memory device from emitting the position information to the register device; and a call reception control device for executing a first process of instructing the communications device to emit call reception information, assigned to a retrieved zone, while referring to the position information registered in the first memory device, and for executing a second process of instructing the communications device, assigned to the preregistered zone, to emit the call reception information without referring to the position information regarding the mobile terminal.

Mobile radio telephone for emitting position information indicating an

A mobile radio telephone apparatus operating in a plurality of zones, where each user operates said apparatus from a mobile terminal in one of said zones. The apparatus comprises P number of mobile terminals in each zone, Q number of communications connecting devices in each zone, and a management connecting device in each zone for recognizing which zone a mobile terminal is located in. The mobile radio telephone apparatus also comprises a controlling unit for controlling the management connecting device so that it operates as an additional communications connecting device in one zone, if one of the P mobile terminals generates a connecting request in the one zone and all Q of the communications connecting devices are already assigned to the other P mobile terminals.
