Abstract

PURPOSE:To avoid useless space and economy for mobile communication without encryption, by providing a encryption device with makes communication as encryption in a radio line commonly and inserting a communication line suitably as required. CONSTITUTION:Between a mobile body M' and a mobile system exchanger MCE', connection is made via a transceiver TRX1 of a base station. When an exchanger MCE' receives a signal representing the mobile body number succeeding to a call- out signal from a mobile body M', this is given to an encryption request identifying circuit PRD contained in a mobile body exchanging controller CONT1. The circuit PRD discriminates the mobile body number if the subscriber requires encryption, and if so, the information is tentatively stored in a storage circuit MEM. Next, in the mobile body M', call processing is made in the path of telephone set TE1 T1 of selector switch S transceiver TRX2 and it is made in the path of base station TRX1 trunk TRK-A for radio line, and trunk TRK-B for exchange network telephone exchanger network, at the exchanger side.
