Abstract
Methods and apparatus for automatically identifying overshooting cells and automatically changing PCIs in cases of actual or possible PCI confusion are described. A cell with a poor KPI, e.g., indicative of failed attachment attempts, is identified. PCI confusion is considered as a possible cause of the poor KPI. A cell which uses the same PCI as the cell with the poor KPI is identified and the coverage areas of the cell with the poor KPI and the other cell using the same PCI is determined. Operating UEs in trace mode combined with deactivation of a cell while the other cell using the same PCI remains active is sometimes used to map cell coverage areas. If the coverage areas of two cells using the same PCI are determined to overlap, a different PCI is assigned to one of the two cells using the same PCI to thereby eliminate possible PCI confusion.
