Network Experience Service Assurance (NESA)
Network Experience Challenges
NESA look and feel
• Drive testing for 4G/5G rollout is expensive and provides partial network performance visibility
• Network and IT intrusive for logs collection
• Missing end-to-end correlations and heavy averaging lead to large time to resolve
• Vendor lock-in on network experience platforms inadequate for multi-vendor scenarios leading to operations, integration challenges
• Domain specific platforms, not network agnostic
Network Experience Challenges
NESA – N e t w o r k E x p e r i e n c e S e r v i c e A s s u r a n c e
What is NESA?
Cloud-native automated platform for network experience and service assurance empowering telecom operators to successfully tackle 4G/5G network performance challenges using existing standard traffic traces
Driveless RAN rollout with MDT
No vendor-lock Single glass pane for operational analytics across
multiple vendor network
Zero-touch network integration
• Driveless 4G / 5G rollout is more cost effective and representative for user experience
• Replacement of drive tests for site certification and quality assessment
• End user experience: data throughput, radio signal strength, voice quality
• Coverage heatmaps analysis, hotspotdetection and network capacity upgrades
• Network-wide automated performance monitoring, reporting, troubleshooting
NESA Use cases
NESA Differentiators
SaaS, microservices, security hardened
Telecom product grade
Data lakes & Agile analytics
Minimization of drive test (MDT) Direct IP
connectivity
Zero-touch integration
Network agnostic RAN, Core, IMS, E2E
Vendor-agnostic, one platform serves all
NESA Technologies
3GPP traffic traces ingestion from any network element allowsINTEGRATION WITH ANY VENDOR EQUIPMENT
Zero-touch network integration, no HW / SW / IT changes, justtypical OSS configuration of network elements for TRAFFIC TRACING
Direct IP connectivity from network elements (e.g. eNodeB) to datacollector allows AUTOMATIC CI/CD ON CLOUD
SECURED ON-PREMISES OR ON PUBLIC CLOUD DEPLOYMENT withencrypted anonymous data protection
Elastic architecture, horizontally scalable with microservices andcontainers to MANAGE LARGE NETWORK TRAFFIC

Minimization of Drive Test (MDT) Features
• 4G / 5G rollout without expensive drive tests improve ROI
• Detailed coverage heatmaps for radio planning
• End user experience: data throughput, voice quality, signal strength
• Troubleshooting single subscriber or eNodeB for specific issues
DATA ANALYSIS & STATISTICS
• CDFs, PDFs for RSRP, RSRQ with
filters on date, eNodeB list, Call Id
and IMSI
• Export to CSV, Time schedules,

Minimization of Drive Test (MDT) Benefits
4G / 5G rollout without expensive drive tests improve ROI
Troubleshooting single subscriber or eNodeB for specific issues
Improved end user experience: data throughput, voice quality, signal
strength
Detailed coverage heatmaps for radio planning
MDT opens an innovative approach to Network Performance Optimization.

Secured cloud deployment
• SaaS on-premises or public cloud deployment with guaranteed complete security with anonymization and encryption of data traffic
• VPN access to GUI application• Define access roles needed in the
application e.g. admin, super user, standard user
• User preferences (eNodeB list, zone, city, etc.)
Data Collection – Traffic Trace
• Network elements configured via OSS to enable “Traffic Trace” 3GPP TS 32.421, 32.422, 32.423 vendor-agnostic fully 3GPP compliant
• trace all active calls in a cell or multiple cells, as well as streaming multiple call traces to specified 3rd party IP address of data collector
• collectors deployed at edge close to eNodeB reduce traffic by up to 95% based on smart traffic filtering (select only Measurement Reports)
• standalone solution reduces integration complexity even for multiple 3rd party platforms, eliminating vendor lock-in and allowing increased flexibility
