Case Study: Vipnet achieves reduced dropped calls and faster subscriber-aware network optimization with Infovista's Xeus

Ensuring Optimal Quality of Experience with Subscriber-Aware Network Optimization

Vipnet, a pioneer in the Croatian mobile market serving over 2 million subscribers, faced growing optimization challenges as a rapid 3G expansion in 2011 increased traffic and strained its optimization and quality teams. High volumes of network data overwhelmed Vipnet’s in‑house tools and made tasks like neighbor optimization and fault resolution slow and labor intensive, so the operator evaluated market options and selected Infovista’s Xeus® to address these gaps.

Infovista deployed Xeus® to automate log parsing and provide smart analytics (dropped/blocked call, smartphone/VIP analysis, GPEH call trace analytics), enabling engineers to geo‑locate and resolve issues faster. The solution produced immediate results for Vipnet—reduced drop rates, faster neighbor optimization, optimal tilt and azimuth settings that cut interference and maximized capacity, and a measurable reduction in man‑hours required to analyze live call traces—delivering clearer priorities and faster remediation.
