Call quality and coverage improvement in mobile wireless communication networks

Described herein is a computer implemented method for improving call quality and coverage of cells (A, B, C) within a mobile wireless communication network (20, 210). Such improvements can be accomplished by adjusting various radio access network parameters. The adjustments may be made at the cell level or at the neighbor level. An iterative process can periodically collect key performance indicator (KPI) statistics from the mobile wireless network. System improvements may derive from one or more rules (240) relating to performance indicators to parameters in the wireless communications network. Each rule can have a unique combination of minimum or maximum KPI thresholds. System issues may be identified when a cell correlates (530) with one or more of the rules which may then suggest one or more parameter changes to reduce the identified system issue. System capacity policies may be provided as limits to the coverage and call quality triggers.
