In an ideal world, mobile networks would be simple, homogeneous entities, and network conditions would easily be managed by radio access network (RAN) engineers, without the need for constant troubleshooting and optimization. In reality, mobile network operators (MNOs) are in a constant battle to meet subscribers network quality expectations, amidst ongoing changes in network utilization patterns and rapidly increasing capacity demands. With mobile networks spanning multiple radio generations, frequency bands and vendors, it is becoming increasingly imperative for mobile operators to continuously optimize their mobile networks, regardless of size and complexity, in order to ensure a high quality of experience (QoE) for subscribers, while keeping OPEX and CAPEX costs in check.

VistaNEO

Taking RF Network Optimization and Troubleshooting Initiatives to The Next Level

In a competitive environment where customer retention is key, mobile operators knowledge of subscribers experience and behavior over time and space is mandatory. A solution that provides such holistic insights for an entire network, 24/7 and across multiple technologies and vendors makes it possible to deliver the optimal network experience.

Powerful Network Optimization Platform For Optimal Network Quality of Service

VistaNEO, InfoVistas solution for holistic mobile network experience optimization, enables MNOs to collect and monitor millions of subscriber-centric events across the entire mobile network. It automatically post-processes and aggregates the call records into rich and accurate network and geo-located subscriber intelligence that RAN engineers can leverage to focus on network troubleshooting and optimization activities that can truly make a difference.

A powerful and scalable, client server-based solution, VistaNEO allows RAN engineers to drill down and carry out in-depth analysis of live, geo-located, subscriber data records to better understand how the network impacts the subscriber experience and to proactively solve network problems before they truly affect subscribers.

VistaNEO Benefits

Smarter network analytics and optimizationVistaNEO accelerates network quality enhancements by making available all the required types of mobile performance data, including rich and accurate subscriber and network intelligence from a single network optimization platform. With built-in optimization analytics, such as neighbor relations, interference troubleshooting and overshooting cells, VistaNEO increases optimization efficiency by quickly and seamlessly performing root-cause analyses for identified problems.

Improving network experience for high-value subscribersVistaNEOs built-in, subscriber-centric KPIs make it easy to quickly identify, analyze and solve QoE issues for a given subscriber, and to determine which subscribers are most impacted by network quality problems. RF engineers can prioritize optimization efforts for the most affected, high-value subscribers, ultimately maximizing customer satisfaction and revenue streams, while minimizing troubleshooting efforts.

Visualize network and subscriber behaviorVistaNEO provides network- and subscriber-level views of the network through accurate, subscriber geo-analytics such as traffic density and RF coverage plots, among numerous other subscriber-focused insights. Its different dashboards, from those with a high-level view of the network to those with detailed, subscriber-specific KPI trends, allow RAN engineers to gain holistic insight into network performance quality and subscriber experience throughout the network across various vendor areas.

Scalable and FlexibleVistaNEO was built to be as flexible as possible. Built upon InfoVistas proven and powerful platform technology, VistaNEO scales according to MNOs growth. Data processing agents are horizontally scalable and flexibly support multiple vendors and technologies. Network data and subscriber analytics and trends can be stored over a period of time for a complete network performance view.

Figure 2. VistaNEOs features allow for a multi-dimensional approach to subscriber and network experience optimization and problem resolution when and where it really matters.

Subscriber InsightVistaNEO includes a quick view of subscriber experience trends, including call-outs for subscribers with the most issues through Worst Performing Subscriber charts. From the charts, RAN engineers can do a direct drill-down to the detailed call analysis, in order to efficiently and effectively find out which subscribers are being affected by which recurring network issues and where.

Network InsightsUnderstand, analyze and optimize network performance across all the different technologies and vendors, and quickly resolve problematic areas with in-depth statistical KPIs. Smooth, drill-down analysis from high-level dashboards to detailed reports reduces optimization and troubleshooting time by providing the right diagnostics, such as the cells with the most issues, which allows targeted troubleshooting in order to improve overall network QoS.

QoS InsightResolve network performance issues related to abnormal events such as dropped or blocked calls. With automated event diagnostics, the root causes of dropped and blocked calls, such as missing neighbors or quality issues, are immediately identified and can be addressed.

Network Optimization & TroubleshootingWith VistaNEO, there is no longer the need to go through tedious and labor-intensive analysis processes in order to detect the cause of poor cell performance or low user QoS, including data throughput and abnormal call events, pilot pollution, overshooting cells and missing neighbors. VistaNEOs built-in algorithm traces L3 messages to get to the root of the problem, applies integrated optimization best practices and in-depth optimization analyses that enable faster and more efficient workflows.

Live Geo-AnalysisPowerful geolocation and visualization capabilities allow mobile operators to understand high traffic locations and to optimize problem areas. RAN engineers can create coverage plots and display abnormal event locations based on real subscriber data, reducing drive testing dependencies.
