Document Type and Number:
Japanese Patent JP2590754
Kind Code:
B2
Abstract:
PURPOSE: To shorten the call processing of a mobile machine and to reduce the scale of a mobile exchange.
CONSTITUTION: When a call comes to a mobile exchange 1, a mobile switchboard 11 refers to position registration information stored in a position registration information storage device 23 to read out a registered identifier corresponding to the mobile, machine identifier of a called mobile machine. The mobile switchboard 11 outputs a call signal to a radio base station having this registered identifier. The radio base station receives the call signal destined for itself to discriminate whether this signal is the call signal or not by a wire transmission/reception equipment 23; and when it is the call signal, this signal is outputted to a call signal transfer device 25. This device 25 discriminates whether this call signal is transmitted from the mobile exchange or not; and when it is transmitted from the mobile exchange, the call signal is sent from a radio transmission/reception equipment 22, and the call signal is transferred to the other radio base stations stored in a position registration area information storage device 24 also through the wire transmission/reception equipment 23 to perform simultaneous calling.
