CONGESTION CONTROL METHOD IN RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a congestion control method in a radio communication system appropriate for suppressing or canceling congestion by accurately performing a communication regulation that does not become an overload for network-side control, in accordance with a call origination/speech situation for each terminal while improving fairness of a communication opportunity between users even under a congested state. ! SOLUTION: A wireless network control station 2 or a ground station 6 supplies call origination regulation notification information BC and a recall regulation time Tr corresponding to a situation of congestion to each of mobile terminals 1a and 1b via a base station 3a or a communication satellite 5 of an area subjected to the regulation. When a new communication request or redialing by user operation is received, in each mobile terminal 1, a random number Xi is generated by a random function generation device, and a coefficient L(N) that is determined significantly in accordance with
