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

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

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
