Vi partners Anritsu to enhance calling experience on VoLTE

Vodafone Idea Limited (Vi) has partnered with Anritsu to enhance the end-to-end calling experience for customers on voice over long-term evolution (VoLTE) in India. Vi has implemented a VoLTE monitoring solution of Anritsu to enable:

• Superior VoLTE experience for Vi users with faster call connectivity and crystal clear sound quality
• Improved efficiency with faster detection and demarcation of VoLTE service issues
• Enhanced view of VoLTE service-specific insights
• Prioritisation of the resolution of issues based on subscriber impact and severity.

VoLTE is a complex architecture with multiple nodes and interfaces, which makes detecting and isolating customer-impacting issues challenging with traditional operations support systems (OSS). Detection of specific customer issues, like muted calls and dropped words, is unavailable in other OSS systems. Anritsu brings enhanced visibility with insights across all VoLTE dimensions like subscriber, device, network nodes, codecs, and cell-id. These speed up the time to identify customer-affecting VoLTE issues and their resolution.

Using Anritsu’s patented anomaly detection on VoLTE, Vi reduced the mean time to resolution of issues by 30 per cent. These issues are detected in real-time, which is pivotal for the subscriber experience of VoLTE. The root causes of the issues are isolated and pushed to the relevant team with actionable intelligence. Anritsu’s full suite of cloud-first applications, including eoMind anomaly detection, are deployed in Vi’s open universal hybrid cloud, contributing to significant savings in capex, opex, resources, and automation investments.

Commenting on the partnership, Jagbir Singh, chief technology officer, Vi said, “Real-time anomaly detection across our VoLTE services allows us to proactively detect, isolate, and diagnose customer-impacting issues. The solution is widely adopted by our operations team and significantly improved VoLTE experience of our customers. Partnering with Anritsu has delivered exceptional benefits to our subscribers, and we will extend the successful approach to enhance other services like international roaming.”

Meanwhile, Ralf Iding, chief executive officer, Anritsu Service Assurance, said, “Anritsu is delighted to partner with Vi to improve the VoLTE network and service experience. Our market-leading machine learning (ML)-based solution leverages closed-loop automation and provides end-to-end VoLTE visualisation, aligning to Vi’s business objectives. Collaborating closely with Anritsu, Vi offers best-in-class VoLTE services. We look forward to our continued partnership with Vi and supporting their commitment to delivering superior experience to their subscribers as they move to 5G.”
