Case Study: North American Cable Operator achieves proactive 4G/LTE service delivery and faster root-cause resolution with NETSCOUT nGenius

North American Mobile Operator Enables Proactive Service Delivery Management for 4G/LTE Network Services

A leading North American mobile operator with more than 90 million subscribers was deploying LTE and IMS to deliver high‑speed data and multimedia services but lacked end‑to‑end visibility into core service‑enabling transactions (attach/authenticate/register and charging/accounting). The operator needed an early‑warning system and clear service visualization to detect performance degradations, pinpoint the location and severity of problems, and shorten time to root cause across 3G and LTE domains.

They extended their existing nGenius deployment with additional InfiniStream appliances and configurable service dashboards to capture deep‑packet data across LTE/EPC, IMS and 3G interfaces, provide real‑time alerts, and enable fast drill‑down to KPIs and protocol-level evidence. The solution delivered proactive service delivery management and faster MTTR—successfully identifying a Diameter/HSS registration fault, validating corrective actions, eliminating access errors, and giving operations teams seamless visibility across networks.
