Satori PCI Handover Failure Reduction rApp

PCI conflicts  including duplicate PCI reuse and mod-N collisions in LTE and 5G NR networks  can cause handover failures, dropped calls, and degraded user experience. These issues may arise from site activations, software upgrades, configuration drift, or manual planning changes.

The rApp continuously monitors topology and performance data, detects PCI conflicts, computes optimized PCI assignments, applies changes automatically, validates post-change handover performance, and rolls back updates if quality degrades. Configurable validation windows and per-cell cooldowns help maintain network stability while reducing the need for manual PCI management.

Traditional PCI planning often relies on periodic manual reviews and static spreadsheets, making it difficult to keep pace with network growth and configuration changes. This rApp continuously analyzes live topology and performance data, computes optimized PCI assignments using graph coloring techniques, and applies updates automatically through network interfaces.

Changes caused by new site activations or manual configuration updates are detected and reconciled within each optimization cycle. PCI management becomes a continuous background process rather than a periodic planning task, with full per cell audit visibility available through decision tracing.
