No room for failure
Tests for every possible scenarios in telecom designed for today's hyper-connected 5G world
Service Parity & Customer experience
Service Parity between 4G/5G NSA and 5G SA – Everything (Services) that works in 4G should work with 5GSA 5G Interworking with existing RAT (4G, WiFi, 3G, 2G) – Testing all possible interworking scenarios between 5GSA and 4G, WiFi, 3G and 2G. Validate the customer experience Corelate live customer behaviour with design – Highlight integration gaps
Advanced Security
User Concealed Identity (SUCI) - Test SUCI with private/public (Home Network Key) pair and 3gpp SIDF functionality SBI over mTLS: - Test mTLS certificate management in network functions using certificate orchestration over CMPv2 and perform the impact assessment of implementing mTLS in the network (eg Physical Tapping / tracing) NF Authorization (oAuth 2.0) - Test access-token authorization requests for specific NF producers based on the allowed NF type and PLMN that are present in the NF profiles NF screening using SBI certificates – Test the additional layer of security in SBI to allow only authorized NF consumers to discover NF producers Security Penetration Testing – 5G Core Applications
Network Slicing
Test end-to-end slice design (RAN, Core, IT, Billing and Transmission) Test integration of network slices Performance testing of network slices; quantify quality of experience within and outside a given slice Network Slice Management: - KPIs of individual network slices using FCAPS - Quality Assurance of network slices using analytics - Network slice augmentation (Scaling) using service orchestrator
Network APIs
Test the 5G network API design involving multiple entities (Device, AF, NEF, 5G Core) Test integration of network APIs into CSPs 5G core network Test Network APIs using real and simulated application functions Network API Management - KPIs of individual network APIs using FCAPS - Quality Assurance of network APIs using analytics
SBI, Redundancy and Resiliency
Test SBI Basic Design - NRF - mTLS - Direct communication between NF consumer and provider Test SBI indirect communication with SCP SBI Redundancy and Resiliency (Load, Capacity, Locality, Re-attempt, Failure) - Connectivity Failure - NF Failure Test End to End 5G Core SBI testing - Direct/Indirect - Resiliency - Load balancing (Weighted, Capacity, Locality)
5G Capable UE behaviour
N1 mode behaviour of different UEs 5G/4G/WiFi interworking behaviour of N1 capable UEs Slicing capability of N1 capable UEs Battery consumption of N1 capable UEs in 5G SA, NSA and LTE Network behaviour when UE toggles N1 mode in 4G/LTE or non-3gpp/WiFi access S1 (non 5G SA) capable UEs behaviour when forced to use SBI
Advanced Capabilities
Testing UE Route Selection Policy Testing Net Slice Admission Control Function Testing Network Slice Selection Function Testing Network Exposure Function

06
Bridge the gap between Telecom and IT
Rest Assured. Tested.
Challenges with 5G Stand Alone
-
Perceived as “complex” – Achieving 4G to 5G service parity is time consuming & expensive
-
Delay in Launch – Very long and expensive testing cycle in Lab & Live to test all legacy services over 5G SA and interworking with 4G/WiFi/2G/3G
-
UE behaviour must be thoroughly tested to ensure no change in customer experience
-
5G SA Performance: Inability to aggregate LTE carriers makes it challenging to equal or surpass 5G NSA performance levels
-
Advanced capabilities – Network Slicing, Network APIs, URSP perceived as technically complex and lacks ecosystem readiness
