A method for a cellular telecommunications network includes selecting a target cell in the cellular telecommunications network, retrieving automatic neighbor relations (ANR) data including neighbor cell list information for a plurality of cells in the network, determining, from the ANR data, first and second cells that are neighbors to the target cell and use a same Physical Cell Identifier (PCI), and at least one of the first and second cells is an inbound neighbor to the target cell, determining that PCI confusion is present between the first and second cells with respect to the target cell, and resolving the PCI confusion.

Method and system for cell identifier optimization

A method for a cellular telecommunications network includes performing a modulo operation on a physical cell identifier (PCI) of a target cell to determine a first PCI mod value, determining first tier neighbors of the target cell, determining that at least one of the first tier neighbors uses a PCI that has a PCI mod value that is the same as the first PCI mod value, comparing a number of handover attempts between the target cell and the at least one first tier neighbor with the first PCI mod value to a first threshold value, and when the number of handover attempts exceeds the threshold value, replacing the PCI of the target cell with a PCI with a second PCI mod value different from the first PCI mod value.

A process for associating a cell with a detected scrambling code in a cellular communications network includes receiving cell data associated with the detected scrambling code, determining a set of candidate cells within a predetermined area, evaluating characteristics of each candidate cell of the set of candidate cells, and associating a cell identifier of a first candidate cell of the set of candidate cells with the detected scrambling code based on the evaluated characteristics.
