  • Patent number: 5666398
    Abstract: A radio telephone system is disclosed to satisfy in the short term basic telecommunication needs of areas which are insufficiently or not yet covered. The system has a number of duplex radio channels (transmission channels) substantially smaller than the number of radio telephone subscribers. These transmission channels are connected to the ports of a telecommunications exchange system which is part of the stationary radio station and which ensures both incoming and outgoing traffic with the public telecommunications network and internal exchanges within the system. Signalling, exchange, management, servicing, and special functions of radio operation between the stationary radio station and the subscriber connection device are ensured by a radio switching device which uses one, or if required, several transmission channels used as organization channels and not connected to the ports of the telecommunications exchange system.
