Abstract

The present invention is a method and system for monitoring and controlling congestion in a CDMA system having multi-user detection capabilities. The method detects congestion in the uplink by calculating noise rise (14) based on user equipment measurements or radio access network measurements. Upon detection of congestion, congestion relieving measures (18) are implemented as needed.
