Abstract
Downlink congestion is accurately detected and congestion control is more effectively provided without decreasing the system downlink capacity. The characteristics of the downlink transmission of the base station are monitored and used to selectively adjust a fast congestion control (FCC) alarm threshold value in each base station. A FCC relief action is initiated upon detecting the downlink power exceeding the FCC alarm threshold value, i.e., potential downlink congestion. The FCC relief action includes temporarily blocking data services in the system or rapidly decreasing the downlink transmit power of the packet data user's Dedicated Physical Channels in the base stations.
