Radio data transmission system for use between fixed base station and mobile station uses multicast radio channel with large number of dedicated channels

摘要

The base station (BS) is situated at the center of a local transmission cell (FZ) and is connected to a base control station (BSC) situated outside the cell. The base station communicates with several mobile stations (MS1-3) inside the communication cell. Stations may be arranged in different multicast groups. The base station may have a high-frequency circuit and a data processor circuit with a bus line, data memory and computer.
