NR Upper Layer vRAN

With data traffic continuing to grow, the virtualization of the upper layer of the Radio Access Network (RAN) software provides service providers with new flexibility which is especially beneficial when deploying street macros and small cells for capacity, and network slices for new applications.

NR Upper Layer vRAN is one of several Ericsson Cloud RAN Architecture options

Cloud RAN Architecture Options 

Virtualized RAN (vRAN): Introducing the split architecture with NR Upper Layer vRAN for greater 4G & 5G deployment flexibility

Distributed RAN (D-RAN): Simple and flat architecture where each radio site has co-located RAN Compute baseband units, enabling relaxed interconnect and simple deployment

Centralized RAN (C-RAN): Colocation of clusters of RAN Compute baseband resources at a common site for maximum interworking and performance in hot spots

Elastic RAN (E-RAN): RAN Compute Baseband interworking across the network enabling tight coordination amongst unlimited number of baseband units

Flexible

NR Upper Layer vRAN moves the control of the user data "higher up" in the network, providing additional deployment flexibility for 5G networks.

Efficient

Large scale deployments of street macros, and the creation of network slices can be achieved more easily and more efficiently with NR Upper Layer vRAN.

Performance

Cloud RAN deployment ensures good RAN Compute baseband coordination for strong network performance.
