The O-RAN Alliance has launched its second open source software release featuring 23 new or updated specifications.
The O-RAN "Bronze" release also includes an initial set of O-RAN use cases and cloud native deployment support options.
Highlights of O-RAN Bronze:
- an initial release of an A1 policy manager and an A1 controller that implements the Non-Real-Time Radio Intelligent Controller (Non-RT RIC) architecture.
- the Near-Real-Time RIC updated to current O-RAN E2 and A1 specifications with 5 sample xAPPs.
- initial O-CU and O-DU Low/High code contributions that support a FAPI framework and integration between the O-DU and RIC with E2 functionality and subscription support.
- a Traffic Steering and Quality Prediction use case leveraging an E2 interface data ingest pipeline to demonstrate the functionality of RAN traffic steering with an E2 interface KPI monitoring capability.
- OAM use cases that exercise Health Check call flows including the Near-RT RIC and its O1 and A1 interfaces.
“The new use cases, the Bronze software release, and the new O-RAN ALLIANCE members are indications that this global forum is working exactly as intended, reaching across borders to drive innovation and build consensus,” said Andre Fuetsch, Chairman of the O-RAN ALLIANCE and Chief Technology Officer – Network Services, at AT&T. “As this coalition evolves, we look forward to seeing how it continues to broaden access to 5G and other new access technologies.”
“Over the past 6 months, O-RAN working groups and the O-RAN Software Community have extensively engaged to achieve tight alignment between the specifications and the Bronze release open source code,” said Chih-Lin I, the Co-Chair of O-RAN Technical Steering Committee. “Specific progress related to both the Non-RT-RIC and the Near-RT-RIC frameworks and associated key interfaces deserves special mention for its importance in enabling AI/ML capabilities in RAN. The O-RAN virtual showcase further demonstrates the growing momentum towards global adoption and deployment of O-RAN solutions.”
“Ericsson is actively engaged in shaping the future of the O-RAN initiative by enabling Non-RT RIC (Non-Real-Time RAN Intelligent Controller) and A1 interface to support fine-grained intelligent steering of the RAN,” said Per Beming, Head of Standards and Industry Initiative in Ericsson. “During OSC Bronze release, Ericsson continued as the key contributor to Non-RT RIC project by improving support for intent based intelligent RAN optimization using A1 interface. This specific capability allows operators to leverage both RAN and non-RAN data to enrich end user experience.”
