Operators can’t “install” agentic AI. They must operationalize ontology-driven agents with governed tool-calling, traceable actions, and observability—then prove ROI in one quarter.
On a live telecom network, the difference between “a model that predicts” and “an agent that acts” becomes operational reality fast—because the next step isn’t a chart, it’s a configuration change, a maintenance trigger, or a parameter update with real business impact. McKinsey’s framing is blunt: AI can deliver improvements only when operators build the operating model around it, including governance and closed-loop mechanics—not merely tooling. (https://www.mckinsey.com/industries/technology-media-and-telecommunications/our-insights/issue-brief-ai-driven-telecom-networks)
Practitioner pressure is understandable. Your KPIs care about uptime, energy, mean time to repair (MTTR), and churn. But your teams also face hard constraints: OSS/BSS integration, alarm fatigue, change control, audit trails, and the sheer risk cost of wrong actions. That’s why “agentic workflows” need an infrastructure layer that can (1) understand what to do and (2) prove what it did—using an approval boundary when the blast radius is unknown.
This article focuses on how telecom operators can operationalize ontology-driven agentic AI for network optimization, predictive maintenance, churn reduction, and 5G/6G rollout—emphasizing infrastructure outcomes and ROI, not vendor claims. The adoption path is the centerpiece: data mesh and governed enterprise assets, tool-calling governance, and operational observability that makes agent actions traceable.
Agentic workflows are not “LLM chat with automation.” In telecom, “agentic” means the system can (a) decompose an operational intent into a deterministic sequence of tool calls, (b) validate preconditions against live or near-real-time state, and (c) persist an auditable execution record linking each decision to measured outcomes.
Concretely, an operator intent like “stabilize PRB utilization in Sector 12 for cell cluster A” becomes a bounded control procedure:
That sequence is what differentiates an agent from a recommender. A recommender can be wrong and still “look right” in dashboards; an agent is required to prove—through explicit preconditions and KPI verification—that the action achieved the operational intent without violating safety constraints.
In Open RAN architectures, similar closed-loop mechanics are already conceptually familiar. The Open RAN “SMO” (Service Management and Orchestration) layer orchestrates RAN operations, and the “RIC” (RAN Intelligent Controller) provides structured control for radio functions. Ericsson and other ecosystem references describe non-real-time and near-real-time RIC functions and the SMO role in hosting AI/ML workflow elements for training and policy guidance. (https://www.ericsson.com/en/reports-and-papers/white-papers/smo-enabling-intelligent-ran-operations) (https://www.juniper.net/us/en/research-topics/what-is-ric.html)
The engineering implication: you need a consistent action model that can work across multiple domains (RAN, core, energy, field operations). That action model must map to tool permissions, data contracts, and observability signals. Without this, agentic AI devolves into a brittle demo that “sounds right” but cannot survive production change management.
Ontology-driven AI means you represent domain entities and relationships in an explicit, machine-readable form (an ontology): for example, cells, sites, radio layers, alarms, failure modes, maintenance work orders, and service-impact mappings. The goal isn’t semantic elegance—it’s traceability. An agent should be able to cite the exact ontology path that justifies a tool call.
In telecom, your “ontology” is often fragmented today. Engineers know it lives in dashboards, runbooks, OSS inventory models, and tribal knowledge. Operationalizing it for agents means formalizing three things:
This is where telecom data mesh matters. A telecom data mesh is an operator-led approach to distributing data ownership and making data products available through governed contracts across domains. Instead of a monolithic lake nobody trusts, you define data products (telemetry, inventory, event history) with quality SLAs and lineage.
McKinsey’s operational emphasis aligns with this: AI delivers when operators restructure network economics and operating model, including disciplined optimization and proactive maintenance mechanics that shift ticket handling and MTTR dynamics. (https://www.mckinsey.com/industries/technology-media-and-telecommunications/our-insights/issue-brief-ai-driven-telecom-networks)
Before you pick agent frameworks, build or formalize the ontology and data contracts for the specific closed-loop workflow you’ll deploy first (maintenance, optimization, or rollout). Otherwise, you’ll spend months reconciling “what the agent thought it saw” versus what your systems actually contain.
A telecom data mesh for agentic AI doesn’t mean “we implemented a data lake.” It means the agent consumes governed data products that come with provenance (where the data came from), freshness (how current it is), and quality (how reliable it is). If you can’t audit a tool call’s inputs, you can’t defend it in change control.
Predictive maintenance is a closed-loop process even when you keep humans in the loop. The agent typically needs:
A real operational signal exists in how some ecosystem actors connect AI-driven workflows to trouble ticket systems. Telefonica Germany’s journey toward autonomous networks is described through an AI-driven predictive maintenance solution integrated with the trouble ticket system for automatic ticket creation and closed-loop operations. (https://info.tmforum.org/Predictive-maintenance-begins-Telefnica-Germanys-journey-towards-autonomous-networks.html)
Similarly, in energy optimization and 5G rollout economics, operators need telemetry-rich closed loops. Vodafone UK’s trial with Ericsson described AI/ML use cases such as “5G Deep Sleep” and “Radio Power Efficiency Heatmap,” and reported measurable energy outcomes in the trial context. (https://www.ericsson.com/en/press-releases/3/2025/vodafone-uk-and-ericsson-trial-ai-solutions-for-improved-5g-energy-efficiency)
Your data mesh plan must include the exact data products the agent will use for decisioning and verification. Draft a “tool-call input contract” before development: telemetry schema, time windows, asset mapping rules, and quality thresholds. This turns agent actions from guesswork into engineering evidence.
Tool-calling governance decides which agent actions are allowed, how they are executed, and when they require approval—and it enables traceability for agent outcomes. Think of it as two layers:
Agent governance frameworks for “agentic AI” are emerging. Singapore’s IMDA launched its Model AI Governance Framework for Agentic AI in January 2026, explicitly framing reliable and safe agentic AI deployment with four core dimensions: bounding risks upfront, meaningful human accountability, implementing technical controls, and enabling end-user responsibility. (https://www.imda.gov.sg/resources/press-releases-factsheets-and-speeches/press-releases/2026/new-model-ai-governance-framework-for-agentic-ai)
Even if jurisdiction differs, the engineering translation is universal. For telecom networks, “risk bounding” becomes concrete policies:
Governance should align with Open RAN “SMO and RIC” control loops. The ecosystem describes near-real-time RIC guidance and the non-real-time RIC role in AI/ML workflow and policy guidance. (https://www.ericsson.com/en/reports-and-papers/white-papers/smo-enabling-intelligent-ran-operations) (https://www.juniper.net/us/en/research-topics/what-is-ric.html)
The governance layer should align with these control loops: tool calls that translate policy into configuration changes must be auditable and ideally routed through orchestrators you already trust (change management, workflow engines, and validation pipelines).
Implement a “go-live gate” for each tool the agent can call. Start with read-only tools (telemetry queries, topology lookups), then move to dry-run configuration diffs, then to staged execution with human approval. You’re not being conservative; you’re making the agent’s first production month survivable.
Operational observability for agentic workflows means you can answer, after the fact:
Some observability vendors and enterprise frameworks describe “agent observability” as tracing tool usage and dependencies end-to-end, not just monitoring a single model call. For example, Dynatrace’s materials describe end-to-end insight through tracing execution flows for agent behavior and tool calls. (https://www.dynatrace.com/news/blog/announcing-agentic-framework-support-and-general-availability-of-the-dynatrace-ai-observability-app/)
For telecom, “green dashboards” are especially dangerous because KPIs can improve while action quality degrades (wrong tickets, unnecessary interventions, or silent misconfigurations that don’t crash immediately). So observability must include action verification. Your agent is only “correct” when it produces the intended operational outcome in the network.
A concrete starting point for observability requirements can be borrowed from how some operators formalize network operations integrations. GSMA Foundry’s coverage of Türk Telekom’s AI-driven inspection and maintenance work stresses the operational outcome (inspection reduction) and implies a measurable workflow integration from AI to field operations actions. (https://www.gsma.com/get-involved/gsma-foundry/gsma_resources/how-turk-telekom-achieved-a-98-reduction-in-site-inspection-time-using-ai-and-computer-vision/)
Vodafone UK implemented Ericsson AI solutions including “5G Deep Sleep.” Ericsson reported that the trial enabled radios to enter an ultra-low energy hibernation state and saving up to 70% energy consumption during low traffic hours. Ericsson also reported reduced daily power consumption of 5G Radio Units by up to 33% across trial sites in London. (https://www.ericsson.com/en/press-releases/3/2025/vodafone-uk-and-ericsson-trial-ai-solutions-for-improved-5g-energy-efficiency)
This is not “AI vendor ROI marketing.” It’s a useful template for instrumenting an agentic workflow:
Below is a visualization of those two reported trial metrics (not a global benchmark, just trial evidence operators can compare against their own energy KPIs).
For energy and optimization workloads, make “tool-call verification” mandatory. Define the success metric you will accept (energy consumption reduction with no KPI regression) and ensure your observability can link each agent action to those metrics.
Telefonica Germany’s predictive maintenance is described as integrated with its trouble ticket system for automatic ticket creation, supporting closed-loop network operations and operational efficiency. The TM Forum case study emphasizes predictability and closed-loop control that improves mean time to repair and network availability. (https://info.tmforum.org/Predictive-maintenance-begins-Telefnica-Germanys-journey-towards-autonomous-networks.html)
What’s operationally valuable here is the workflow boundary. The agent doesn’t just produce a risk score. It triggers a ticketing action in an operator-controlled system. That’s the difference between “prediction” and “agentic workflow.”
To deploy this pattern safely:
For predictive maintenance, your first agent should own a single, high-leverage action boundary (ticket creation or work-order recommendation), not a broad “repair anything” autonomy claim.
Agentic AI adoption fails when teams treat architecture as a “phase” rather than as the delivery mechanism. The solution is an adoption sequence that forces integration mechanics early, and defers autonomy until evidence exists.
Pick one closed-loop workflow that maps cleanly to network KPIs:
Then instrument it end-to-end: telemetry to decision to tool call to KPI verification. Even before the agent is “smart,” you’re building the observability spine.
To make this measurable (and not just “logging enabled”), define these operational primitives up front:
workflow_run_id + cell_id + config_version).Your goal in Phase 1 is to ensure you can answer, quickly: “When the agent acted, did the network behave as expected vs. when it didn’t?”
Formalize the ontology entities and relationships for that workflow, then connect the agent to data products with lineage and quality thresholds. This is where most “agentic” efforts die because teams cannot reconcile asset IDs, time windows, or event taxonomy across systems.
Operationally, “contracting” means more than agreeing on schemas. It requires:
This prevents the agent from acting on partial or mismapped truth—which is one of the most common failure modes in real telecom deployments.
Introduce tool-calling with permissions:
Use a governance framework logic similar to IMDA’s four dimensions (risk bounding, accountability, technical controls, end-user responsibility), translated into telecom operational controls. (https://www.imda.gov.sg/resources/press-releases-factsheets-and-speeches/press-releases/2026/new-model-ai-governance-framework-for-agentic-ai)
To keep staging safe, define which “blast radius” is acceptable before you automate it:
This is how you turn governance from policy text into operational control.
Your business target must be measurable within one quarter. McKinsey reports that at scale AI capabilities have enabled operators to achieve 30 to 70 percent fewer troubleshooting tickets, 55 to 80 percent reductions in network operations center costs, and 30 to 40 percent faster MTTR, alongside improvements in customer experience. Those figures are not operator-specific here, but they define what “ROI evidence” should look like if you instrument correctly. (https://www.mckinsey.com/industries/technology-media-and-telecommunications/our-insights/issue-brief-ai-driven-telecom-networks)
Below is a second visualization focused on these three ranges that define ROI targets for operational observability and ticket economics.
Commit to an adoption plan where observability and tool-call governance are built in weeks, not months. Then measure ROI within 90 days using ticket economics and MTTR or energy outcomes—or you’ll only discover integration debt later.
For 5G/6G rollout, the operational “action boundary” is often planning and verification: which sites to activate, which parameters to stage, how to validate readiness in OSS inventory, and how to ensure the rollout doesn’t break customer SLAs.
You can operationalize ontology-driven agentic workflows by mapping rollout artifacts:
Although many AI-RAN discussions exist, operators can anchor agent rollouts in what ecosystems already publish about Open RAN control components and AI orchestration in SMO/RIC layers. Ericsson’s SMO documentation emphasizes non-RT RIC supporting AI/ML workflow including model training and policy guidance, which is exactly where rollout decisions need governance. (https://www.ericsson.com/en/reports-and-papers/white-papers/smo-enabling-intelligent-ran-operations) (https://www.juniper.net/us/en/research-topics/what-is-ric.html)
One operator-facing reality check: not every rollout step can be automated. When rollout risk is high, you can still use agentic workflows in a semi-autonomous mode: the agent generates verified staging plans and the operator approves tool calls.
Separately, Nokia and other vendors describe “deep sleep” and traffic-aware energy savings as AI-enabled features. For instance, Nokia’s description of extreme deep sleep mode claims up to 95% energy consumption reduction during inactive periods by predicting traffic patterns and optimizing activation thresholds. This is vendor-published but useful as a parameter for agent-targeted verification. (https://www.nokia.com/blog/ai-builds-the-foundation-for-zero-energy-use-at-zero-traffic/)
Treat rollout as an integration project with observability requirements. Instrument which agent outputs were used to approve rollout actions, then verify KPIs after each staged activation. Your goal is not “fully autonomous rollout.” Your goal is “fewer rollout surprises with traceable decision evidence.”
To make rollout observability operational (not retrospective), define a rollout-specific “proof of safety” template for each staged batch:
In practice, this is how you convert “rollout risk” into a measurable engineering envelope—so future autonomy can expand only when evidence supports it.
Telecom managers often ask for “the best architecture.” In practice, the most decisive artifacts are boring but critical:
A governance framework for agentic AI that emphasizes risk bounding and technical controls supports this approach even beyond any single country. IMDA’s model is explicit about bounding risks upfront and implementing technical controls. (https://www.imda.gov.sg/resources/press-releases-factsheets-and-speeches/press-releases/2026/new-model-ai-governance-framework-for-agentic-ai)
For procurement and program management: require instrumentation deliverables in your delivery contract. Don’t accept “we integrated AI” without evidence that you can answer: what was the exact tool call, what data product inputs were used, and what outcome happened.
If you want ROI, shift procurement language from “AI capability” to “governed action evidence.” In the first quarter, you should be able to replay agent decisions, audit tool inputs, and show KPI deltas tied to those actions.
Mandate traceable tool-calling as a production requirement: build agentic telecom ops around governed execution boundaries, ontology-grounded decisioning, auditable data contracts, and operational observability that ties every action to measurable KPI outcomes.
Telecom operators are narrowing AI budgets toward RAN automation, energy savings, and maintenance workflows that can prove ROI during 5G-Advanced rollout.
