Abstract

A system and a method for controlling the radio signal quality between a plurality of mobile stations and a plurality of base stations connected to a mobile switching center of a code division multiple access (CDMA) cellular telecommunication system. Each base station is adapted to measure the quality of each active CDMA communication link and to report for each active CDMA radio communication to the mobile switching center the corresponding measured communication signal quality. The mobile switching center is adapted to perform an averaging process on the reported quality measure values, in order to calculate a recommended quality measure threshold value. The base stations are adapted to receive the recommended threshold value for use in an uplink closed-loop power control algorithm for the mobile stations.
