AI-Powered Anomaly Detection for Telecom Networks

Polystar’s software solutions use AI and machine learning to automatically detect anomalies in telecom networks, accelerate Root Cause Analysis (RCA) to identify the problem, and speed up issue resolution for operators.

Extend Kalix Analytics with Automated and Real-Time Anomaly Detection

Filtering issues from the mass of data you are exposed to is a growing challenge for telecommunications operators. With today’s network complexity, manual investigations and legacy alerting mechanisms are not enough to identify and categorize anomalies at the scale needed.

At Polystar, we’ve introduced an automated approach that enables your team to operate more efficiently, exposing and prioritizing anomalies, both individually and in clusters. 

AI-Powered Anomaly Detection: Explained

AI-powered anomaly detection means that you can automatically track important network and service KPIs in real-time, so you can focus on monitoring those that matter to your business.

Anomalies represent deviations from expected network, traffic, service, and customer experience data in your network, indicating service-impacting issues. AI-powered algorithms will learn from your data and calculate the needed thresholds to automatically identify anomalies for different time series KPIs. Anomalies are then grouped and tagged with priority indicators and show the number of customers impacted.

How Does Automated Anomaly Detection Boost Network Performance?

AI-powered anomaly detection can help boost performance for telecom operators in a number of ways. Through real-time monitoring, machine learning, and intelligence, Polystar’s software tools identify issues early, improve the MTTR, and allow for advanced analysis of both the problem and the solution.


Self-Adapting Thresholds

The AI powered anomaly detection function continuously learns from your unique input data to automatically adjust thresholds, so it’s optimized for your network – enhancing accuracy for your team and driving focused incident responses.

 

Cluster Anomalies

Group anomalies that relate to specific services, and view a timeline that highlights severity and frequency. You can view segments and dimensions associated with each deviation, enabling you to prioritize actions.

 

AI Summaries

Add your own troubleshooting steps and comments to detected anomalies through the integrated knowledge base management backend – so the solution learns from your inputs and generates tailored summaries and recommendations.


How AI-Enabled Anomaly Detection Impacts Telecom Costs

AI-powered anomaly detection lowers telecom operating costs in multiple ways:

  • Preventative versus reactive maintenance: by spotting issues early and identifying the root cause, repairs can be made to the network before larger breakdowns and more expensive fixes. Targeted issue identification also means fewer resources are wasted during repairs.

  • Fraud prevention: Anomalous traffic and usage data can point to unauthorized network users

  • Increased operational efficiency: AI and machine learning capabilities mean that more advanced, adaptive data can be gathered about network usage and performance, which can be used to increase network efficiency.

Polystar’s software tools also reduce the number of human hours needed to analyze and monitor data, saving further labor costs so important human attention can be allocated to tasks that most need it.

FAQ - Anomaly Detection in Telecom Operations


  • AI-powered anomaly detection uses machine learning to continuously analyze network, service, and customer experience data to identify unusual patterns that may indicate faults, performance degradation, capacity issues, or emerging service risks.

    Unlike manual monitoring, AI can detect subtle deviations across large volumes of data in real time, helping telecom operators identify issues earlier and respond faster before customers are affected.

  • Anomaly detection helps reduce Mean Time to Repair (MTTR) by identifying issues as soon as they emerge and providing immediate visibility into abnormal network or service behavior.

    Advanced AI models can correlate related events, highlight likely root causes, and prioritize incidents based on impact. This enables operations teams to troubleshoot more efficiently, accelerate resolution times, and minimize service disruptions.

  • Traditional threshold monitoring relies on predefined limits and generates alerts only when a KPI exceeds a set value.

    AI anomaly detection learns normal behavior patterns from historical and real-time data and can identify unexpected changes even when thresholds are not breached. This enables earlier detection of emerging issues, adapts to changing network conditions, and reduces the need for constant manual threshold tuning.

  • False positives often occur when monitoring systems flag expected or harmless changes as faults. Common causes include static thresholds, seasonal traffic variations, planned maintenance activities, network upgrades, and temporary usage spikes.

    AI-driven assurance solutions reduce false positives by understanding normal operational patterns, incorporating context, and distinguishing genuine service risks from routine fluctuations, helping teams focus on the most important issues.
