O-RAN specification based Open X2 interface testing between Altran gNB and Altran MeNB.

Device Under Test

  • Altran gNB (O-CU and O-DU)
  • Altran MeNB
  • Altran 4G EPC

Test scenarios introduction

Altran has participated in O-RAN India Plug Fest event to showcase the O-RAN specification based open X2 interface between MeNB and gNB. The scenario demonstrated Altran gNB based on x86 platform, which supports the O-RAN specification based X2 interface and has the ability of inter-operating with other vendors MeNB component.

Testing Results/Summary

  • Scenario 2, U-Plane test

Altran complied to the O-RAN defined X2 interface between MeNB and SgNB and successfully demonstrated the ENDC X2 Setup and SgNB Addition procedure:

• MeNB initiated ENDC X2 Setup

• SgNB initiated ENDC X2 Setup

• SgNB UE Addition to create 3x bearer type at SgNB

• SgNB UE Release procedure

Further as part of its roadmap, Altran will continue to focus on enhancement and optimization of 5G CU/DU stack to add support for the E2 interface messages based on based on O-RAN specifications, along with 3GPP release16 compliance.

Benefits for the Industry

  • Altran MeNB can be integrated with any Vendor SgNB, which is based on O-RAN defined X2 interface
  • Altran SgNB can be integrated with any Vendor MeNB, which is based on O-RAN defined X2 interface
