Abstract

PROBLEM TO BE SOLVED: To enable a slave unit to wait for reception of an incoming call from a cell type mobile radio telephone set even in a callable range set to a master unit. SOLUTION: A cell type mobile radio telephone receiving part 105 which can receive the signals from a cell type radio telephone base station is added to a master unit. When a slave unit is kept in a cordless telephone communication mode, the master unit monitors the call-in signal and the position register signal received from the cell type mobile radio telephone base station and notifies the slave unit of detection of a signal sent to the slave unit by the cordless telephone communication via a cordless telephone transmitting part 103. Thus the slave unit can answer the call-in and the position registration of both cordless telephone and cell type mobile radio telephone.

According to the present invention, when the base unit is in the range in which the base unit can talk with the handset unit in the second mode, it receives the signal from the cellular mobile radio telephone base station, and the base unit receives the signal in the second communication mode. Since the received signal is transmitted to the slave unit, the slave unit can receive an incoming call regardless of whether the slave unit is in the first mode or the second mode. Even under the circumstances, it becomes possible to provide a radiotelephone device and a radiotelephone system capable of receiving both incoming calls by a cell-type mobile radiotelephone by one telephone number.
