Abstract

PURPOSE:To prevent the incorrect usage of a mobile set, by determining the key number corresponding to a mobile set number in advance, and connecting the mobil set to a subscriber via the base station only when this key number is in agreement with the key number stored in the mobile set. CONSTITUTION:When a mobile set is in calling, the key number is transmitted in addition to the calling discrimination signal and mobile set number. The key number is a value determined according to the mobile set number. The base station checks if the mobile set number is registrated or not and the key number is corresponded to the mobile set number or not, and only when YES, the mobile set is connected to the subscriber of fixed station. In case of mobile station having incoming calls, the base station transmits the incoming call indentifying signal, mobile set number to be called and the key corresponding to the number. The mobile set receiving the signal in matching with the mobile set number of itself, further checks if the key number is in agreement, and if YES, it transmits the response signal for connecting operation, and if NO, the response signal is not transmitted and no connection is made.
