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)

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.
