KDDI and Radisys announce breakthrough in 5G network slicing trial

Radisys and KDDI Research have announced a demonstration of 5G RAN slicing with the MNO. It succeeded in creating two separate traffic streams, with different latency requirements, on a single radio unit (RU), connected to multiple virtualized central (CU) or distributed (DU) units.

The first slice was for enhanced mobile broadband and spanned two DUs in an edge cloud site and a CU user plane (CU-UP) in a regional cloud site. The second slice was created for ultra-reliable low latency (URLLC) services, using another pair of DUs in the edge cloud.

Radisys provided an end-to-end configuration consisting of:

  • 5G NR gNodeB in Standalone mode operating in sub-6 GHz frequencies along with a RAN controller
  • 5G Core Network including Access and Mobility Management Function (AMF), Session Management Function (SMF) and User Plane Function (UPF)
  • eMBB and URLLC service functionality portioned in edge and regional clouds

Arun Bhikshesvaran, CEO of Radisys, said: “This demo goes beyond the typical single DU and RU binding and really brings to the forefront how mobile operators will manage their networks with intelligent edge deployments and scale into regional clouds to optimize efficiency and operational costs in order to realize the benefits of 5G disaggregation.”
