5G Core

Why 5G Core Validation Matters

A 5G Stand-Alone core is really a cluster of tiny apps (micro-services) that all have to answer thousands of requests every second. If too many phones try to register at once—or a new software release slips in a bug—the whole fabric can stall and customers lose service. Automated “lab storms” with Spirent Landslide let you hit the core with the worst-case load, trigger faults on purpose and watch every KPI in real time, so surprises never reach the live network.

5G Core

How the Test Workflow Looks

Subscriber & Slice Generator

Spawns millions of virtual UEs and slice-aware QoS flows.

5GC Micro-services “cloud”

Drives traffic through every AMF, SMF, UPF, PCF—just like live

Fault Injector

Drops interfaces or overloads nodes to probe resilience under stress.

Real-time Dashboard

Streams pass/fail KPIs to Grafana for instant, drill-down insight.

Outcomes You Can Count On

Key Benefits

Launch-day Confidence

Prove registration-success > 99.99 % and slice latency < 50 ms in-lab, not in production.

Faster Releases Automate every regression run from your CI/CD pipeline and cut release cycles by up to 3×—as Telefónica achieved

Lower Field-Fix Cost Catch signalling storms and capacity limits before they hit live subscribers, slashing unplanned OPEX.

Security & Compliance Ready Run SCAS, DDoS and replay-attack suites alongside functional tests for one clean “go/no-go”.

Use Case

When Do You Need 5G Core Testing?

Massive UE & Slice Load

Millions of UEs, gNodeBs and multiple network slices processed without KPI breach.

Core Upgrade Regression

Every nightly build passes full KPI & slice-scalability suite in < 6 hrs.

Security / SCAS Validation

Core withstands signalling floods and drops replay attacks on N3 interface.

VoNR & IMS over 5G

Voice & video sessions establish within spec on the first call after upgrade.
