O-RAN Alliance conducted the first global Plugfest to foster adoption of open and interoperable 5G Radio Access Networks. As outlined in the Press Release the North America Plugfest and proof-of-concept were conducted within the COSMOS testbed that serves as an Open Test and Integration Center. It was hosted by AT&T and focused primarily on the validation of the O1 and A1 interfaces:
- Physical Network Function (PNF) Plug and Play, a 3GPP-aligned O1 use case that provides a means for service providers to collaborate with equipment vendors to have PNFs discovered by Service Management Orchestration (SMO) via a PNF registration handler, was demonstrated by Nokia, CommScope and Ericsson. Remote SMO functions were also demonstrated with connections to labs in France and Germany.
- Bulk Performance Management Data Collection was demonstrated by Ericsson and Nokia.
- O1 interface functionality for Configuration, Performance, and Fault Management of multi-vendor equipment via a vendor-agnostic SMO was demonstrated by Altiostar, CommScope, and Samsung.
- A1 interface functionality to optimize PCI/RSI for a large-scale RAN simulator using a closed loop automation framework was demonstrated by IBM, Tech Mahindra, Wipro and highstreet technologies.
- Convergence of the Open Fronthaul Management Plane specification with O1 interface was demonstrated by Samsung.
