This use case started in Casablanca Release. We have carryover items and enhancements. Please see 5G - OOF (ONAP Optimization Framework) and PCI (Physical Cell ID) Optimization for the base wiki page for this use case.

Development Status

ProjectPTLJIRA Epic / User Story*Requirements
AAI
James Forsyth

  1. No impact. ConfigDB objects for pnf shall be aligned with with A&AI (e.g. use the same primary key for pnf, which is expecte to be pnf-id)
DCAE

Vijay Venkatesh Kumar

  • Epic: DCAEGEN2-1108: DCAE Support for OOF-PCI solution
  • US DCAEGEN2-1109: Onboard SON Handler microservice to DCAE
  • US DCAEGEN2-1110: VES Collector for FM/PM data from RAN-SIM PNFs
  • US DCAEGEN2-1111: FM/PM Database for SON solution
  • US DCAEGEN2-1116: Preparation steps for onboarding of SON Handler MS
  • US DCAEGEN2-1219: Seed code check-in of SON Handler MS


  1. SON Handler Microservice shall be onboarded onto DCAE (DCAEGEN2-1109)
  2. A VES Collector shall accept FM/PM VES messages from RAN Simulator and publish to DMaaP - DCAEGEN2-1110
  3. SON Handler microservice shall filter for specific alarms (e.g. PCI Confusion) and trigger OOF Optimization as needed - DCAEGEN2-1109
  4. Implement PostgreSQL database to store FM/PM data and any other data needed by the SON Handler Microservice. This database provide a query interface so that the SON Handler MS can read and write data. - DCAEGEN2-1111
  5. The SON Handler microservice shall filter specific FM/PM messages published by the VES Collector and write to the FM/PM database. DCAEGEN2-1109
  6. The SON Handler MS interfaces to Policy, OOF, SDN-C, ConfigDB shall be modified as needed by DCAE onboarding. e.g. MS shall receive configuration policy via DCAE Controller - DCAEGEN2-1109
  7. Microservice shall support centralized ANR SON functionality to modify neighbor cell relations based on handover KPIs. DCAEGEN2-1109
 OOF
 Sarat Puthenpura
  1. US - OPTFRA-416


  1. OOF PCI Solver and interface shall support at least two optimization objectives (e.g. minimize changes, minimize PCI confusion)
  2. OOF PCI Solver policy shall use a PCI range specified in the configuration policy
  3. OOF shall provide a joint PCI/ANR solver which will optimize PCI and also recommend a removal of a neighbor relation if there PCI allocation is difficult for a cell which also has a neighbor link for which the successful_handover KPI is below a pre-specified threshold
 Policy
 Pamela Dragosh

EPIC POLICY-1438

US POLICY-1463:

US POLICY-1464:

EPIC POLICY-1438

  1. US POLICY-1463:
    1. Policy module shall support handling of partial success where only some of the PCI change actions from a set of changes are successful (e.g. allow partial changes, revert to previous state)
    2. Policy CLC shall co-ordinate between PCI SON Control Loop (CL) and some other control loops (CL) which are acting on the same cells.
  2. US POLICY-1464: Covers all additional/changed configuration related aspects, for e.g., algorithm names/constraints for optimization (e.g., minimize number of PCI values used, minimize number of changes), thresholds, etc.
    Note: Including CLAMP for Dublin is not recommended based on guidance from Policy and DCAE PTLs.
 SDC
 Michael Lando

  1. SON Handler Microservice shall be onboarded manually and not via SDC (as agreed with DCAE PTL)
 SDNC
 Dan Timoney

(Carryover items from Dublin)

-SDNC-430: Modify RAN informational model and yang model for RAN
-SDNC-431: Implement config DB and REST API (SDN-R / OOF interface)
-SDNC-432: Interfacing SDN-R with Policy
•Receive DMaaP message in CL format from Policy (Modify Config message using existing LCM API), send netconf message changing PCI value to cellID as specified, update config DB, and publish change on DMaaP (DMaaP client is available and can be called)
-SDNC-432: Receive netconf notification from RAN, update configDB, and publish change on DMaaP

  1. SDNC-430: Modify RAN informational model and yang model for RAN
  2. SDNC-431: Implement config DB and REST API which can be used by ONAP component. API shall support all CRUD operations. Schema and data model shall be aligned with A&AI.
  3. SDNC-432: Interfacing SDN-R with Policy - Receive DMaaP message in CL format from Policy (Modify Config message using existing LCM API), send netconf message changing PCI value to cellID as specified, update config DB, and publish change on DMaaP (DMaaP client is available and can be called)
  4. SDNC-433: Receive netconf notification from RAN, update configDB, and publish change on DMaaP
(RANSim)

  1. RANSim shall send FM/PM data (e.g. PCI confusion alarm, Handover KPI) to VES Collector
  2. Provide UI support to ANR updates @sa

*Each Requirement should be tracked by its own User Story in JIRA 


Integration Testing

Note: The OOF-PCI use case implementation and testing will be done at the Rutgers University Winlab ONAP Wireless Lab. Access is available to interested ONAP members.
Please see this page for details: Open Wireless Laboratory (OWL) at Wireless Information Network Laboratory (WINLAB)


Note: DMaaP should be setup for most of the test cases below.
