Network Experience Service Assurance (NESA)

Network Experience Challenges

• 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

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, hotspot

detection and network capacity upgrades

• Network-wide automated performance

monitoring, reporting, troubleshooting

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

3GPP traffic traces ingestion from any network element allows

INTEGRATION WITH ANY VENDOR EQUIPMENT

Zero-touch network integration, no HW / SW / IT changes, just

typical OSS configuration of network elements for TRAFFIC TRACING Direct IP connectivity from network elements (e.g. eNodeB) to data collector allows AUTOMATIC CI/CD ON CLOUD

SECURED ON-PREMISES OR ON PUBLIC CLOUD DEPLOYMENT with

encrypted anonymous data protection

Elastic architecture, horizontally scalable with microservices and containers to MANAGE LARGE NETWORK TRAFFIC

NESA

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, Custom dashboards RSRP, RSRQ, SINR

SIGNAL LEVEL MAP

per call path RSRP, RSRQ, SINR

HEATMAPS

RSRP, RSRQ, SINR, Throughput with filters on date, eNodeB, IMSI

EVENT MAP

• CDR (call drop rate), CDR at eNodeB level, overshooting eNodeB

• KPIs export to CSV

MAP DISPLAY of IMSI search and calls

CALL DETAILS

• General details, Map trajectory

• Troubleshooting: Call flow UE, eNodeB, MME • RSRP, RSRQ during call

GPS GEO-LOCATION correlated with

radio events from 3G, 4G, 5G from Release 10 onwards

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

Radio Experience with NESA

Public cloud Operator data center Operator on premise/edge

NESA Architecture

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 3

_{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 3

_{party platforms, eliminating vendor lock-in and}

eNodeB Cell Trace activation via OSS
