METHOD AND APPARATUS FOR CONTROLLING SIGNAL QUALITY IN A CDMA CELLULAR TELECOMMUNICATIONS SYSTEM

摘要

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