Summary

Primary Goals for Non-RealTime RAN Intelligent Controller (Non-RT-RIC) - Release G

  • 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.
  • Non-RT-RIC will define and coordinate rApps (Non-RT-RIC applications) to perform Non-RT-RIC tasks.
  • Non-RT-RIC will host the A1 interface (between NONRTRIC & near-RT RICs )
  • Non-RT-RIC will also host the new R1 interface (between rApps and SMO/NONRTRIC services)

Overall objective for the G Release

In the G Release we focus mainly on prototyping building blocks to support Non-RT-RIC Apps ("rApps") and R1 interface concepts from O-RAN. For the R1 interface we will focus on enabling Service Management & Exposure (R1-SME), and demonstrating Data Management & Exposure (R1-DME).
 

G Release Priorities

  • Study & prototype Coordinated Service Exposure (SE)

    • Continue SE contribution building on the manual approaches already studied/completed.
    • Create/apply K8S configurations to isolate platform services and rApp microservices, then configure controlled secure access between service
    • Prototype CAPIF compliant API for Service/rApp registration/discovery, and service provider/consumer registration/configuration

  • Data Management & Exposure (DME):

    • Pre-spec O1 PM via pre-spec R1 DME demo
    • Configure & connect to PM data - collected by SMO (ONAP)
    • Collect, Filter & Coordinate Delivery of PM data from DMaaP/Kafka to rApps over R1 (ICS)

  • General activities

    • Continue to provide spec-compliant implementation of A1-Policy & A1-EI functions
    • NONRTRIC source-code repository re-organization
    • Continue to integrate and deploy SMO/NONRTRIC platform/rApps in OSC integration environment.
    • Continue to expand NONRTRIC test platform & testsets
    • Show various versions rApps implemented/deployed as holistic “Automation Compositions” (ref ONAP ACM)
    • Continue to provide & integrate strawman rApps to comply with OSC RSAC integration usecases.

G Release Feature Scope

  • NONRTRIC Functions:
    • OSC Information Coordinator (controller – Data Management & Exposure & A1 Enrichment Information (A1-EI) Job management)
    • OSC Non-RT-RIC Control Panel (GUI – for A1-P & A1-EI Job management)
    • OSC A1 Simulator (a stateful test stub to simulate near-RT-RIC end of A1 interface – A1-P & A1-EI)
    • Initial OSC APP catalog (for registering/querying APPs)
    • K8S Helm Chart LCM Manager - for APP µServices etc. (ONAP & OSC)
    • Exposure Gateway Functions
    • Coordinated service exposure for R1 interface
    • DMaaP/Kafka → Information Producer Mediator
    • Integrated A1 Adapter from ONAP (A1 Policy (A1-P) controller – mediation)
    • Integrated A1 Policy Management Service from ONAP (A1 Policy (A1-P) controller)
    • Manager for rApps / Automation Composition Manager (ONAP & OSC)

Release G Priorities

Count of Epics (20 issues), User Stories, Tasks, and Issues:  (455 issues)

  • R1 Service Exposure & Management

    • Continue work of Service execution platform extensions (K8s, Istio, Keycloak, OPA, Gateway) to enable service isolation & exposure
    • Extend Release F prototyping of 3GPP CAPIF-aligned Service Exposure Manager function (& API)

  • R1 Data Management & Exposure

    • Align with emerging proposals for R1-DME where possible
    • R1 DME Data Catalog support in NONRTRIC ICS 
    • R1 Data delivery & filtering (kafka & REST)

  • rApp Manager

    • Build on ONAP “Automation Composition” model & platform to implement rApp use cases
    • Demonstrate controlled on-boarding & LCM rApps with & without µService
    • Overlap with Service Exposure work to examine role of an rApp Manager to support controlled exposure & LCM of µService and non-µService parts of an rApp
    • Investigate where parts of rApp executes in KNative environment (e.g. ML model part of an rApp)

  • Continue A1-Policy & A1-Enrichment-Information evolution (& R1-A1)

    • A1 Spec evolution
    • Southbound: A1 Interface
    • Northbound: R1-A1(P) & R1-DME Interfaces
  • Sample use cases (rApps)
    • Requirements Drivers for rApp/R1 development
    • High degree of cross-project integration activity

  • Testing, Maintenance & Housekeeping

    • Function Test & Integration Test environment,
    • Support integration, deployment & configuration of SMO/Non-RT-RIC related functions & usecases in OSC Integration env.
    • Project coordination, Documentation, Delivery, Reporting, Cross-project alignment, Community demos, O-RAN Standardization support, etc.
