Product Overview

What it is...

Advanced VoLTE Service Intelligence

Mobileum’s VoLTE Analytics provides CSPs with real-time visibility into voice quality, using control plane data and VoLTE-specific KPIs to pinpoint issues from cell to subscriber level. Through intuitive dashboards and location-based overlays, operators can track metrics like MOS, jitter, and packet loss to rapidly detect anomalies, enhance performance, and ensure service continuity.

and why it matters...

Assure Every Call Counts

As CSPs migrate to LTE and 5G, maintaining high-quality voice services is critical to user satisfaction and retention. VoLTE Analytics empowers operators to detect degradation early, reduce voice-related complaints, and deliver consistent call quality across evolving networks. With proactive monitoring and instant alerting, teams can minimize churn and optimize SLA compliance.

Industry Challenges

Eliminate VoLTE Blind Spots. Improve Every Call.

1
  • Voice quality issues often go undetected until customers complain, due to a lack of end-to-end visibility across the VoLTE stack
2
  • Urban areas and handover regions see significant drops in MOS scores, often falling below 3.6, leading to poor user perception and escalations
3
  • Up to 21% of mobile service complaints are linked to call quality, contributing to higher churn rates and strained customer service operations
4
  • Troubleshooting is slowed by siloed data and manual correlation, delaying time-to-resolution and increasing operational costs
