Abstract
Abstract A mobile radio communication system having a plurality of fixed stations (2,3; 50) respectively connected to a plurality of subscriber's lines extending from a telephone exchange, and a plurality of mobile stations (4,5; 10) linked with the fixed stations (2,3; 50) through radio channels. Each of the mobile stations (4.5; 10) effect speech via one of the fixed stations (2.3; 50). The system comprises means provided for each fixed station (2,3; 50) for transmitting rate charging information from the telephone exchange to a mobile station (4,5; 10) under speech, and rate collecting means provided for each mobile station (4,5; 10) and being responsive to the rate charging information to vary its content.
