New RUST framework based xApp hw-rust will be added in J release. 

New xApp to support E2SM CCC will be added in this release  

J release plan:

Near-Real-time RAN Intelligent Controller Platform (E2 Interface) (RICPLT)

Theme: Make the platform more robust in handling E2AP, conflicts and A1

Original primary goals based on contributions from Nokia, Samsung, Capgemini, HCL Alexandre Huff (UTFPR), GS Lab and Abhijit G:

  • Additional messages: modify src code to be more lenient in ordering of IEs in ASN.1 (RIC-1030, GS)
  • tests with mock replies for subscriptions, registrations and alarms in xapp framework for Rust (RIC-1028, AG)
  • Handling of E2 Error Indication from E2 node at E2M and Sub manager (RIC-1024, N)
  • Graceful Handling of Unsupported E2AP Procedure at E2T (RIC-1023, N)
  • Handling of SCTP Abort message from E2 Node (RIC-1022, N)  
  • remove leading zeros in gnb, cu, du ID , MCC and MNC (RIC-1021, N)
  • Abnormal signaling process cause E2Term crash (Bug RIC-1002, N)
  • Handling of RIC Error indication _during_ E2 setup (RIC-997, N)
  • E2 Conflict management between xApps (RIC-993, CG)
  • implement test cases for xapp-frame-cpp (RIC-950, H)
  • Support Startup/Health script demonstrating release capabilities (RIC-926, H)
  • A1 mediator testing in nanobot (RIC-926, H)
  • xapp testing nanobot enhancements: wider coverage of functionality, e.g., Subscription deletion (RIC-860, H)
  • scale-in and scale out using K8S operators (details still open) (RIC-1048, S)

Link to planned Jira work items: link

Completed Items:

  • Graceful Handling of Unsupported E2AP Procedure at E2T (RIC-1023, N)
  • Handling of SCTP Abort message from E2 Node (RIC-1022, N)  
  • Abnormal signaling process cause E2Term crash (Bug RIC-1002, N)
  • Handling of RIC Error indication _during_ E2 setup (RIC-997, N)

Achieved J release highlights = high-level release notes (23-06-2024) below (note that the release image list is here: TODO)

  • Robustness in E2 AP procedure handling by means of handling unsupported E2AP Procedures, RIC Error Indication and SCTP abort messages.
  • Then near real times installation now uses newer k8s version 1.28.x.
  • Upgraded kong to newer version 2.38.0

The J release has 7 bugs fixed.


Filled in end-of-release checklist:  Release criteria checklist - Release J

PTL: Abdul Wahid W 

Status 23-06-2024: From the 13 epics planned (link) we implemented 3 (link). 10 items have been moved out of the J release, e.g, because of implementation delays (link). Additionally, we fixed 7 bugs (link). One security issue is pending RIC-1001(CVE-2023-41627) to be resolved and will be attempted in next release. 


J release source code, container images and deployment instructions

The list of container images for the release (link). A demo video for the J release deployment is available at the top of the demo page and shows

  • how to deploy the near-RT RIC platform,
  • compile connect the E2 (e2 node) simulator from the OSC simulator project and
  • compile the hw-go xapp from the xapp project and use the dms_cli to deploy it and check the E2 subscriptions the xApp created.

Code coverage: Code coverage reports (current coverage and a list of components that still needs to be set up Jenkins job for auto-generation of the reports as part of CI)


Mapping of new features to O-RAN Spec

RIC-1024, RIC-997 relate to correct implementation of ErrorIndication as defined in E2AP in addition to other failure cases that are defined in E2AP.

RIC-993 is an implementation of E2 guidance for conflict mitigation (see RICHARCH 6.0 draft). As WG3 is still in the process of specifying this we may have to adapt later.

Operation and Maintenance (OAM)

Primary Goals:

  • update of O-RAN WG10 VES message bodies
  • update of O-RAN WG4 optional VES bodies
  • update of OAM-Controller to OpenDaylight version Potassium-SR1
  • support of other O-RAN-SC projects (e.g. SMO, Non-RT-RIC, O-DU, INT) based on RSAC and other input.
  • support of OAI and nephio integration with O-RAN-SC related to OAM
