The document outlines an algorithm for analyzing and optimizing PCI collisions (mod(3), mod(6), mod(30)) across network cells based on input site information and RSRP levels. It details procedures for generating comprehensive reports, thematic maps, and optimization strategies to minimize collision areas and improve network performance. The optimization process results in increased access success rates and throughput by adjusting antenna parameters and implementing a smart distribution of PCI values.

- 9. ADVANCED FEATURE (1) 1. Single Cell PCI Tuning Base on the output report, you will get the mod(3),mod(6) and mod(30) collision cells list, and then system will provide you a candidate value list support you to find the prober PCI. The following table is an example which system will show you after big data analysis.PCI MOD(3) MOD(6) MOD(30) Cross Area Cell Distance 128 2 2 8 0 Without Collision Cell 179 2 5 29 8 1.3KM 234 0 0 24 12 0.9KM 156 0 0 6 14 0.8KM
- 10. ADVANCED FEATURE (2) . Whole network PCI smart distribution Once the RSRP confirmed, the system can fill the following table, and then implement the algorithm to distribute PCI with different mod(3),mod(6) and mod(30) values for the cells which get cross area from maximum to minimum. Finally, we will make the network with minimum cross coverage area with mod(3),mod(6) and mod(30) collision. And also base on the big data analysis, we will put solution as well, to adjust some particular cell’s antenna down tilt to make the mod collision as small as possible.
