Near-Real-time RIC X-APPs (RICAPP)

Near-Real-time RIC X-APPs (RICAPP)

Primary Goals: Expand the community on open source xApps for O-RAN SC. 

 Update and maintain the existing xApps to latest releases (currently J Release).

Enhance the set of open source xApps in support of the RSAC use cases (traffic steering, network slicing) and add new xApps.

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:  

  • New HW-Rust xApp to support RUST framework. - Added 

  • New ad-cell xApp to detect cell level anomaly. - Moving to next release

  • New ccc xApp to support E2SM CCC. - Moving to next release

PTL: @Sunil Kumar 

Jira: Count of Epics, User Stories, Tasks, and Issues:  Total (10)

Completed Epics & Story:

RICAPP-232 - hw-rust xApp for i-release

Completed Tasks

RICAPP-233: Missing Readiness and Liveness Probes in kpimon-go xApp

J release highlights/accomplishments:

  • HW-Rust xApp is added to support the new xApp framework.

  • AD & QP xApp are maintained to support J-release. 

  • KPIMON-Go bug fixes update. (Missing Readiness and Liveness Probes in kpimon-go xApp )

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

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: @abdulwahid.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.
