Case Study: Turkcell (Turkey’s leading mobile operator) boosts 4G/LTE performance and cuts MTTK/MTTR by up to 80% with NETSCOUT nGeniusONE

Prominent Eastern European Service Provider Turkcell Maximizes Its 4G/LTE Wireless Network Performance and Service Delivery

Turkcell, Turkey’s leading mobile operator serving over 35 million subscribers across Turkey and Cyprus, needed to guarantee superior 24/7 service quality for its 3G/4G/LTE network. The operator lacked end-to-end, traffic-based visibility of LTE control and user planes, session tracing, and proactive signaling intelligence, which made rapid problem identification and prevention difficult and led to lengthy war-room incidents and customer-impacting service drops.

By deploying NETSCOUT nGeniusONE with Adaptive Service Intelligence (ASI), Turkcell gained continuous, unified visibility into MME/P‑GW/S‑GW signaling and user-plane traffic for rapid triage and proactive alarms. The solution cut war-room incident time from 30+ hours to 5–10 hours, reduced Mean Time to Knowledge by ~75%+, shortened service disruptions 50–74%, lowered MTTR by ~80%+, and reduced CAPEX/OPEX by 10–24% through tool consolidation — materially improving network performance, operations productivity, and subscriber experience.
