cell density and complex interaction between HetNet layers

great customer experience (QoE)

Traditional network KPIs is not enough. We need to know more about the subscriber perceived quality

poor RF performance devices, etc.)

Network Issues
(Coverage, Quality, etc)

High Value Subscriber

Network Performance

Understand Subscriber Pain Points

Identify The Root Cause Of Problems

Prioritize, Solve And Optimize

Focus On What Matters

QoE

Visibility

Analytics

Optimization

Network Information

Subscriber Information

Visualize network and subscriber behavior

Correlate information for complete diagnostic of issues

Be aware of subscriber perceived performance

Web Server

main storage repository for the call trace data and network configurations

Scheduling Database Tasks
Reports Creation

delivery of web and services to the clients

to unique subscriber perceived performance indicators

Subscriber Quality Analytics

Intelligence needed to troubleshoot and enhance subscriber’s QoE

Proactive Subscriber Issue Mitigation

Quickly detect and troubleshoot problems before it impacts QoE

Subscriber Group
Quality Assurance

Ensure high value customers are provided the best possible network experience available

Network Quality Assurance

Enhancing traditional PM visibility with subscriber aware performance data

issues – inability to provide appropriate response

Visualize network and subscriber behavior – Plot reports and events of all or specific individual positioning

Location based subscriber analytics - identify both deficiencies and opportunities

“Virtual” drive test to quickly assess network quality perception and manage subscriber complains

and event positioning
P3M Propagation Model, Antenna Model and Geodata will be used to generate Geo-located data
Geo-located data stored in Oracle Database
VistaNEO R2.0 will have 50m binning
All coverage plots and event positioning is viewable in Xeus Client
Benefits
Accurately plot individual subscriber location and isolate their RAN related problems to clearly understand the subscribers QoE

correlation methodology required between heterogeneous data for actionable insights

Full set of subscriber experience metric analytics to guide with troubleshooting/optimization prioritization

Correlate information across different nodes for a complete optimization view of network

Smooth drill down analysis from high level to detail troubleshooting. Quickly provide right diagnostics

Increases optimization efficiency by quickly and seamlessly performing root-cause analyses for identified problems

a costly affair in terms of time and resources

No ability to segment quality experience for different group of users

Geolocated individual/group subscriber quality data increase efficiency and removes guesswork

Shift optimization strategies based on subscriber perceived KPIs instead of network/cell KPIs

Focus efforts on high value users

Not all customers are equal. Ensure high value customers are provided the best possible network experience available

Group KPI Analysis
Subscriber Group-Cell KPI Analysis
Users can create customizable Subscriber Group with the specific IMSI for the group
Capable of viewing cell KPIs that the Subscriber Group IMSI’s have established their call
Further drilldown from Subscriber Group to Subscriber Summary/Trending and Call Records

Benefits
Focus efforts on high value users
Shift optimization strategies based on subscriber perceived KPIs instead of network/cell KPIs
Geolocated individual/group subscriber quality data increase efficiency and removes guesswork

in attending to subscriber complaints due to Insufficient data

Quick search for key subscribers and provide diagnostics and analysis experience by the subscriber

Historical data can be stored and used as analysis of performance trend

24x7 Aggregation provides high granularity and understanding of subscriber experience

Quickly detect and troubleshoot problems before it impacts QoE

and accurate subscriber and network intelligence on a single solution

Improve Network Experience For High-value Subscribers
Subscriber-centric KPIs to determine which subscribers are most impacted by network quality problems

Visualize Network And Subscriber Behavior
Combine subscriber intelligence with network performance for a holistic perspective into network quality

Scalable and Flexible
Scales according to MNOs’ growth with support for multiple vendors and technologies.
