O-RAN Software Community at the O-RAN ALLIANCE and University of New Hampshire (UNH-IOL) Workshop on Open Source

By Blog

The O-RAN Software Community (SC) is pleased to share that we will be in attendance at the O-RAN ALLIANCE Open Source Focus Group (OSFG) / University of New Hampshire Interoperability Laboratory (UNH-IOL) Workshop on Open Source, taking place October 1–2, 2025 at the University of New Hampshire Interoperability Labs in Durham, NH, USA.

This workshop, co-sponsored by the O-RAN ALLIANCE OSFG and UNH-IOL, will bring together open source projects and community participants from across the end-to-end mobile network ecosystem. The discussions will span Radio Access Network (RAN), Core, Infrastructure, and Cloud, with a focus on promoting alignment, integration, and collaboration between projects.


Why This Workshop Matters

Open source is central to the vision of O-RAN, helping to ensure openness, interoperability, and innovation across Radio Access Networks. The workshop will provide an opportunity to:

  • Review and refine the role of open source in O-RAN’s roadmap and strategy
  • Exchange insights across related communities and complementary projects
  • Drive practical steps for cross-project alignment and coordination in areas such as RAN (including the RAN Intelligent Controller, or RIC), management/control, testing, and cloud infrastructure
  • Explore how shared development can accelerate adoption and innovation across the ecosystem

By participating, the O-RAN SC looks forward to contributing to these conversations and reinforcing the importance of collaboration between open source and standards efforts.


O-RAN Software Community Perspective

The O-RAN SC plays a critical role in delivering open source implementations that bring the O-RAN ALLIANCE’s architecture and specifications to life. Our community is advancing projects that are directly relevant to the workshop’s focus areas, including:

  • L-Release Updates: The upcoming release continues to expand support for interoperability, performance, and integration across the RAN ecosystem
  • Integration and Testing: O-RAN SC contributes to end-to-end testing frameworks that help accelerate adoption and deployment of O-RAN solutions in real-world environments
  • RIC Innovation: Through ongoing development of the Non-Real-Time (Non-RT) and Near-Real-Time (Near-RT) RIC, the community is enabling intelligent, flexible, and interoperable RAN management
  • Collaboration Across Ecosystems: O-RAN SC actively works to align with complementary open source and standards communities, ensuring that our collective efforts are greater than the sum of their parts

We look forward to sharing our progress and learning from other participants, with the goal of strengthening the entire open RAN ecosystem.


Agenda Highlights

The two-day agenda includes:

  • Project Introductions: Updates on scope, features, roadmaps, and activity levels across various open source initiatives
  • Breakout Tracks (Birds of a Feather / BOF): Dedicated sessions focused on RAN (including RIC), management/control, integration and testing, and cloud/infrastructure
  • UNH-IOL Tour: A chance to see the lab’s world-class interoperability testing environments
  • Open Source Common Vulnerabilities and Exposures (CVE) Discussions: Exploring processes and approaches to security management in open source projects

Each track will provide a readout and recommendations back to the broader group, helping to shape next steps for integration and collaboration.


Join Us

The workshop is open to all participants from the industry. O-RAN ALLIANCE membership is not required. Both in-person and virtual attendance options are available, and lunch will be provided for onsite participants.

📅 Date: October 1–2, 2025

Collaboration and Coordination: OSFG Gathers in Kista to Advance Open Source Alignment

By Blog

The Open Source Focus Group (OSFG) of the O-RAN ALLIANCE convened an ad-hoc meeting on May 23, 2025, hosted by Ericsson in Kista, Sweden. The goal: to identify key open source initiatives relevant to O-RAN, evaluate testing infrastructure needs, and begin planning a collaborative workshop for later this year. The event brought together participants from the O-RAN Software Community (SC), O-RAN Working and Focus Groups, and multiple member companies across the ecosystem.


Key Objectives of the Meeting

  • Strengthen awareness of O-RAN-related efforts in open source communities.
  • Explore collaboration opportunities for testing, orchestration, and management tools.
  • Address infrastructure funding challenges.
  • Align on planning for a dedicated OSFG workshop later in 2025.

OSFG Mission and Opening Remarks

The meeting began with a restatement of OSFG’s mission, led by Co-Chairs Irfan Ghauri (EURECOM/OpenAirInterface), James Li (China Mobile), and David Kinsey (AT&T), supported by Martin Skorupski (Highstreet Technologies). The group reaffirmed its commitment to openness, transparency, and non-confidential discussion per O-RAN ALLIANCE guidelines.


Technical Presentations and Community Mapping

A series of technical presentations offered insight into open source workstreams intersecting with O-RAN priorities:

  • Robert Schmidt (OAI): Shared updates on network functions and near-RT RIC.
  • Sagar Arora (OAI): Presented on cloud infrastructure projects like Nephio and O2.
  • Martin Skorupski (highstreet technologies): Discussed managing O-RAN network functions in open source.
  • John Keeney (Ericsson EST): Provided insight into ONAP/OSC/Nephio SMO and Non-RT RIC integration strategies.

Building Bridges with Open Source Projects

OSFG is actively working to align with other Linux Foundation and CNCF projects. Efforts include outreach and coordination with:

  • ONAP, OpenDaylight, Nephio, Anuket (O-Cloud, Test Specifications)
  • xTesting, L3AF, Essedum, and potential collaboration with CNCF projects such as CAMARA.
  • 5G Super Blueprint/CNTI: Relevant test catalog use cases were discussed, though more engagement is needed.

The group discussed possibly inviting representatives from these projects to the next OSFG workshop. 


Security and the EU Cyber Resilience Act

A brief update on the EU Cyber Resilience Act (CRA) was delivered by Jimmy Ahlberg (Ericsson). Key takeaways:

  • No current legal liability for OSFG or O-RAN SC under CRA.
  • Nonetheless, the group acknowledged a need to develop a consistent security posture, especially regarding CVE reporting and resolution.
  • OSFG supports a transition toward a Zero Trust Architecture but recognizes current codebases are still based on trust assumptions.

Sridhar Rao (Linux Foundation) led a discussion on O-RAN SC’s CVE process—covering scanning, dashboard reporting, and plans to bring on interns to address critical issues by the end of 2025. The group is also exploring whether CVE data should be published on [cve.org] and/or in blog posts.

A proposal was made to request funding for security interns via TOC (Technical Oversight Committee). The broader question of each project’s security stance (“want to fix,” “not interested,” etc.) remains open and will be addressed at the project level in O-RAN SC meetings.


Strengthening Cross-Org Collaboration

The OSFG officially acknowledged the signed Memorandum of Understanding (MoU) between O-RAN ALLIANCE and the Linux Foundation Networking (LFN), which establishes a basis for inviting LFN participants into OSFG activities. The meeting explored ways to streamline the invitation process for recurring contributors.


Next Steps and Upcoming Workshop

The group concluded with action items to support an upcoming workshop tentatively targeted for September 2025. Nephio is already planning a face-to-face event, and a joint session with OSFG/O-RAN SC was proposed. The group aims to:

  • Finalize dates and agenda.
  • Reach out to relevant open source projects for participation.
  • Confirm venue logistics and shared funding options.

Looking Ahead

The OSFG ad-hoc meeting in Kista underscored the importance of open collaboration, strategic alignment, and technical integration between the O-RAN ecosystem and open source communities. With a renewed focus on testing infrastructure, security posture, and a shared workshop agenda, the group is poised to enhance the impact of open RAN across global deployments.For additional details or to get involved, please visit the O-RAN SC website.
