CIRCUIT MANAGEMENT METHOD FOR MULTI-BEAM MOBILE SATELLITE COMMUNICATION SYSTEM

摘要

PURPOSE: To attain decentralized control and also to attain the dynamic channel assignment through a simple control by fixing the beam frequency in a corresponding area based on the instruction given from a base station and then deciding a feeder link frequency. CONSTITUTION: A base station controller 10 which controls the call of a beam area 18 assigns an idle radio communication circuit 16 to a corresponding mobile station 17 among those managed radio communication circuits. Under such conditions, a transceiver device 12 is instructed by the controller 10 to set a circuit in the area 18. The device 12 sets the assigned circuit frequency and the beam frequency in the fixed and variable states respectively and sets again this variable beam frequency in the area 18. Then the feeder link frequency is generated and a radio circuit is set.
