Abstract

Abstract A computer implemented method and apparatus for determining if a wireless telecommunication system is operating at a reduced capacity is provided. The method and apparatus utilize call processing information associated with every sector/carrier within a CDMA base station to determine if any sector/carrier is operating at a reduced capacity while also being limited by power control (i.e., power control is blocking new users from gaining access to the sector/carrier even though the sector/carrier is operating at a reduced capacity). Thus, the method and apparatus detect blocking faults affecting the capacity of the CDMA system.
