Welcome to the Bronze release page for the O-RAN Software community          

This page contains all the information specific to the Bronze release and frozen code (code freeze = Jun-14, 2020) and documentation. The main trunk will continue on to support future releases.

This is the second release and is in partnership with the O-RAN Alliance. The specification and software are being worked at the same time and the software is considered pre-specification software.

The projects have limited capabilities which will increase over future releases.

See Requirements and Software Architecture under Committees and Projects for more details on current activities.

Second release capabilities include contributions under the following projects:

  • Non-Real-time RIC (A1 Interface) (NONRTRIC)
  • Near Realtime RAN Intelligent Controller Platform (E2 Interface) (RIC-PLT)
  • Near Real-time RIC X-APPs (RICAPP)
  • OAM (O1 Interface)
  • O-RAN Central Unit (OCU)
  • O-DU High
  • O-DU Low

Near real-time RIC X-APPs (RICAPP)

Primary Goals: This includes open source sample xAPPs and platform applications that can we used for integration, testing, and demonstrations.

Bronze Feature Scope: Support Bronze use cases by developing and evolving existing xApps. For the traffic steering use case, we are extending the existing KPIMON xApp and developing new TS, QP, and QP Driver xApps using the different programming langauges supported by the RIC platform. For the health check use case we are developing a demo xApp that supports the A1 health check and extending existing xApps with more thorough liveness checking from K8s and new statistics/alarming APIs provided by the RIC platform.

Near Realtime RAN Intelligent Controller Platform (E2 Interface) (RIC-PLT)

Primary Goals: Develop platform for xApp hosting with stable APIs for xApps using RIC's E2 interface, xApp management interface and other auxiliary xApp interfaces, like a database storage interface.
Bronze Feature Scope: Adapting RIC from pre-spec to WG3's first formal E2 protocol specification (for communication with RAN nodes, like CU/DU). Implement netconf-based O1. Enhance RIC's messaging solution (RMR) to achieve higher throughput, various health check capabilities including a capability to ping E2 nodes via E2 and to do a health check of the A1 interface, better failure handling in various components, ...

  • Jira: 61 epics: link (requires free LinuxFoundation account). Items that we worked on already before the first formal development are marked as Bronze-R3 in JIRA "fix release" (13 = 5 (in progress) + 8 (done)) and the ones to be worked on during the five three-week sprints in Bronze-R4 Feb-3 to May-17 (48 = 7 (in progress) + 1 (done) + 40 (not yet started)). For useful near-RT RIC JIRA links check §8 in Jira usage conventions.
  • Legal aspects related to automatically using WG3 ASN.1 of E2APv1.0 still open. Thoralf to send information to Jinri by Friday this week.
  • Samsung's Arun started working RIC-203 and RIC-95
  • Demos of sprint D2 (Feb-23 - Mar-12) planned for Thursday, Mar-12, 9am ET (note special summer time adjustments in this week in other locations). Thoralf will add event to groups.io calendar. After this demo every three weeks some date & time.

Non-Real-time RIC (A1 Interface) (NONRTRIC)

Primary Goals:

The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.

Bronze Feature Scope:
Initial design and start implementation of NONRTRIC Platform.
Continue evolution of A1 interface.
Continue evolution of A1 Policy Management functions.
Modeling and implementation of the Non-RealTime RIC aspects of the "Health Check" and "Traffic Steering" use cases

Limitations/Dependencies:

  • FAPI Implementation – Dependency on O-DU Low to open source WLS files, interface files
  • Testing: Currently only some unit testing can be done due to lack test infrastructure i.e UE or UE simulator, O-RU, O-CU and core components.
