How Are Operator Networks Using LLMs?


As telecom networks become more software-defined and data-driven, the pressure is on operators to boost efficiency, reduce downtime, and stay ahead of increasingly complex demands.
Our latest research has identified several key ways that large language models (LLMs) are now stepping into the telecom space; not as chatbots, but as intelligent agents capable of transforming network operations:
Resource Allocation
At the heart of any telecom network is the challenge of resource allocation; ensuring bandwidth, compute, and spectrum are distributed effectively to match user demand.
LLMs help operators take this to the next level by continuously analysing real-time network data and traffic patterns. By understanding fluctuations in usage, they can proactively reallocate resources to high-demand areas, balancing loads and preventing bottlenecks. This results in better network performance, particularly during peak times, without overspending on capacity that may go unused.
Network Configuration
Manual configuration of network parameters is time-consuming, error-prone, and increasingly impractical in large-scale, dynamic environments.
LLMs enable automated configuration by interpreting documentation, learning from past setups, and adjusting parameters to match current needs. Whether deploying new sites or reoptimising existing infrastructure, LLMs can streamline this entire process; resulting in faster rollouts, fewer configuration errors, and a lighter workload for network engineers.
Anomaly Detection and Resolution
Network anomalies, from signal interference to routing failures, can severely impact service quality - and go undetected by traditional network maintenance systems.
LLMs, however, excel at identifying patterns and spotting irregularities in complex datasets. By continuously learning from network logs and behaviours, they can detect anomalies as they emerge, diagnose the root cause, and either trigger an automated fix or provide engineers with clear, actionable recommendations. This dramatically reduces MTTR and helps maintain high service availability.
Threat Detection and Mitigation
With cyberattacks on the rise, operators are under pressure to secure their networks in real time.
LLMs play a vital role here by spotting unusual traffic behaviours and correlating signals across diverse data sources - from network logs to system alerts. Unlike traditional security tools that rely on known signatures, LLMs can identify novel threats based on behavioural anomalies. This allows them to flag potential intrusions early and recommend mitigation strategies or automatically activate protective protocols; resulting in a more agile and adaptive security posture.
Predictive Maintenance
Downtime is costly - and often preventable. LLMs can process vast amounts of historical performance and maintenance data to predict when components are likely to fail.
Whether it’s detecting overheating in base stations or identifying early signs of fibre degradation, LLMs enable operators to act before issues cause outages. By integrating with maintenance systems, they can also schedule proactive repairs and automatically generate work orders, minimising disruption and extending the lifespan of critical infrastructure.
These five capabilities only scratch the surface of what LLMs can offer. As networks evolve to support 5G, edge computing, and even early 6G experimentation, the need for adaptive, intelligent operations will only grow - and when combined with other AI models and real-time analytics, are well-positioned to become the decision-making engine behind next-generation networks.
