Automating 5G Core Testing Across Multi-Vendor Cloud-Native Environments

Validating 5G standalone (SA) core network functions requires testing across cloud-native, microservice architectures where multiple vendor solutions run in a carrier-operated cloud. The shift to containerized deployments means the responsibility for verifying service performance no longer falls to network vendors alone — operators must independently validate that each network function performs under real-world conditions.

The test environment must account for Kubernetes orchestration behavior, container and pod lifecycle events, infrastructure resource contention, and the interaction of over 15 nodal functions across control and data planes. Engineers need to characterize how failures at the cloud-native infrastructure layer — node outages, memory and CPU exhaustion, network latency, packet loss — propagate to 5G service key performance indicators (KPIs) such as session establishment, registration, and handoff rates. Without this correlation, performance issues and costly outages reach live networks undetected.

5G Core Network Performance Solution

Validation of 5G SA core performance requires a platform that generates real-world control and data plane traffic for millions of subscribers across complex, multi-vendor cloud-native deployments. The Keysight 5G core emulation and test automation solution addresses this through four test domains: 3GPP compliance verification; capacity and performance testing; control plane security validation; and cloud-native function (CNF) resiliency testing. Managed test case libraries — spanning hundreds of cases for compliance, capacity, performance, and security — are maintained as 3GPP standards and requirements evolve, reducing the time and expertise needed to keep pace with frequent releases.
