AI-Powered RAN Fault Management, delivered fully on-premises

How a Tier-1 telecom operator in India replaced a reactive, alarm-heavy NOC model with Ops Singularity's agentic AI fault management, running entirely inside its own data centre, with no dependency on public LLMs.

Industry: Tier-1 Mobile Operator Scope: SNOC · RAN Fault Management Deployment: 100% On-Premises Data: Fully Sovereign Duration: 1–1.5 Years
~60%Alarm noise reduced through AI correlation & deduplication
~50%Faster mean time to resolve (MTTR) across incident families
~60%First-time-right resolution on defined incident types
~40%Improvement in NOC L1/L2 headcount efficiency
20–40%Fewer incidents via proactive prediction (phased)
100%On-prem inferencing, zero public-LLM dependency
01

The Challenge

The operator runs one of India's largest radio access networks: hundreds of thousands of sites and millions of cells generating alarm volumes in the order of ~12.5 million alarms per day. Fault management was still anchored to a reactive, rule-based, alarm-centric operating model that no longer scaled.

Alarm floods & fatigue

Static, hardcoded correlation rules missed complex multi-domain patterns and buried real incidents under symptomatic noise.

Slow, SME-dependent RCA

Root-cause analysis meant multiple experts manually interpreting logs, KPIs, topology and history, driving high MTTR.

Low first-time-right resolution

Manual playbook mapping led to mismatched steps, repeat tickets and bouncing incidents.

Purely reactive posture

Incidents were handled only after a hard failure or threshold breach; no early anomaly forecasting or prevention.

Touch-heavy operations

L1/L2 triage, diagnostic validation and recovery all required manual intervention, inflating headcount and cost.

Strict data sovereignty

Network, customer-impact and topology data could not leave approved environments, ruling out public or commercial LLM endpoints entirely.

02

The Solution

A single agentic AI platform modernised RAN fault management from reactive and manual to intelligent, proactive and closed-loop. Six coordinated capabilities turn raw operational signals into a unique actionable incident, an evidence-grounded root cause, and approved action, with a human-approval and governance band across every stage.

Flow 01Centralised Data House

Consolidates alarms, KPIs, tickets, inventory & topology into one normalised source of truth, with topology stitching.

Flow 02SA / NSA Correlation

LLM-based primary-vs-symptom reasoning, 3GPP-grounded and topology-validated, emits a clean AI incident with confidence & citations.

Flow 03ML Anomaly Detection

Statistical & time-series ML surfaces degradation signatures ahead of service-affecting alarms. ML-only, no LLM.

Flow 04GenAI RFO & Action Planning

Auto-generates operator-grade RFO, RCA and Plan of Action on approved templates, with ticket enrichment & closure.

Flow 05Communication Automation

Right message to the right stakeholder across email & SMS: SLA timers, escalation and delivery tracking.

Flow 06Prediction & Forecasting

Time-series ML forecasts capacity exhaustion, congestion and service degradation, driving preventive maintenance.

Supervisor & Governance across every stage: RBAC, confidence-and-action policies, human approval gates, configurable guardrails, and an immutable, fully auditable reasoning chain for every decision. Every incident and RFO is grounded in approved knowledge, 3GPP standards, OEM documentation and historical RCA, and carries source citations, reason codes and a confidence score. High-impact actions route through human approval, and resolution outcomes feed back continuously to retrain detection models, so the system gets sharper with every incident.
03

Built for On-Premises, Sovereign Deployment

The defining constraint was data sovereignty: operational, customer-impact and topology data could not leave the operator's approved environment. Ops Singularity was deployed entirely on-premises, both the platform and the AI models, so intelligence runs where the data lives.

Platform · On-Prem

The platform, inside the perimeter

  • Cloud-native, private deployment. Kubernetes-native architecture deployed inside the operator's own data centre, no reliance on external hyperscalers.
  • Carrier-grade resilience. N+1 high availability, multi-replica services, auto-scaling and DR-ready design for 24x7 SNOC operation.
  • Data never leaves the estate. Integrates with the inventory, fault and performance systems already in place; data stays within approved boundaries end to end.
  • Enterprise-grade security. SSO/MFA, role-based access at platform and service level, service-to-service encryption, secrets management, encryption in transit & at rest.
  • Immutable audit. Every prompt, retrieval, tool call, approval and action is logged with a unique transaction ID for complete traceability.
AI Model · On-Prem

The AI models, in-house

  • On-prem LLM inferencing. Generative AI served on dedicated in-house GPU infrastructure; model selection restricted exclusively to on-premises LLM services in the operator's workspace.
  • Zero public-LLM dependency. No prompt, alarm, ticket or network detail is ever sent to a commercial or public LLM endpoint.
  • Domain & OEM-aware. On-prem fine-tuning and retrieval-augmented generation over 3GPP, OEM and historical RCA knowledge produce telecom-grade, operator-specific answers.
  • ML models trained on operator data. Anomaly-detection and forecasting models are trained, versioned and retrained in-house with drift detection, never externalised.
  • Guardrails at every interaction. Configurable input/output scanners block prompt injection, sensitive-data leakage, hallucinated RCA and unapproved actions.

The Impact

Moving from a reactive, manual model to an AI-driven, closed-loop one changed the economics of the NOC: less noise, faster resolution, fewer repeat incidents, and a smaller, higher-value operations footprint.
