Introduction to LTE S1 Analyser

The LTE S1 Analyser from Melrose Networks is a real-time platform for inspecting LTE S1/S1AP signalling from one or more mobile network operators. It combines a high‑performance rules engine with machine‑learning–based anomaly detection to surface unusual mobile device behaviour and operational threats. A dashboard console provides live situational awareness on a map, device and threat tracking, and interactive rules management.

Designed for defence, network operators, security teams, and engineering analysts, the platform ingests signalling events from live network captures or archived traces, enriches them with cell location data, and correlates activity over time and geography. A horizon‑aware pipeline tracks entities across rolling windows, tolerates late or out‑of‑order data, and produces actionable alerts backed by transparent rule statistics and ML scores.

Alerts can be sent using protocols such as SAPIENT to external C2 or C4I platforms.
