Test scenarios introduction

  • Scenarios Performance

UE E2E multiple attach/detach with Physical Handset (5 times)

The purpose of the test is to validate the real UE attach/detach call flow to the 5G NR core emulator (5GC) for 5 times through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Fronthaul (7-2x split). For these scenarios the gNB should connect/release the UE context and report the same to the 5GC.

Pinging from Application server
& Pinging from UE

The purpose of the test is to validate the real UE can ping the application server connected to 5GC through the WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul. This is required to successfully test any uplink/upload data function on the UE.

Subsequently, validate the application server connected to 5GC can ping the real UE through the WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Fronthaul. This is required to successfully test any downlink/download data function on the UE.

Ping Timing and Latency - Average

The purpose of the test is to validate the timing and latency statistics of ping from real UE to application server connected to 5GC through the WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Subsequently, validate the timing and latency statistics of ping from application server connected to 5GC to real UE through the WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Throughput Testing (DL + UL) UDP

The purpose of the test is to validate the average throughput rate of UL and DL UDP traffic through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul and with real UE in good RF conditions.

Throughput Testing (DL + UL) TCP

The purpose of the test is to validate the average throughput rate of UL and DL TCP traffic through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul and with real UE in good RF conditions.

Multi-User Call setup [1: max: 10] attach

The purpose of the test is to validate the average throughput rate of UL and DL UDP traffic through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul and with real UE in good RF conditions.

Single UE maximum spectral efficiency, DL

The purpose of the test is to validate the single UE peak throughput in DL through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Multi-UE, maximum cell spectral efficiency, DL

The purpose of the test is to validate the multiple UE’s throughput in DL through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Single UE maximum spectral efficiency, UL

The purpose of the test is to validate the single UE peak throughput in UL through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Multi-UE, maximum cell spectral efficiency, UL

The purpose of the test is to validate the multiple UE’s throughput in UL through WNC O-RU and Wiwynn/ASTRI O-DU/O-CU connected via O-RAN Open Fronthaul.

Testing Results/Summary

In the tests, WNC O-RU connects over O-RAN Open Fronthaul 7-2x (CAT A) split to Wiwynn/ASTRI O-CU/O-DU.

WNC and Wiwynn/ASTRI tests mostly focused on the end-to-end performance with single UE and multiple UEs. Based on the screenshot from Keysight emulators, we validated that the measured throughout is the same as the generated traffic for both downlink and uplink directions.
