-Description
-~~~~~~~~~~~
-
-The 5G OOF-PCI use case is an implementation of a **SON (Self-Organizing Networks)**
-algorithm for Physical Cell ID (PCI) optimization and the centralized Automatic Neighbor Relations
-(ANR) function (blacklisting a neighbor for handovers) in a 4G/5G network using the ONAP
-Optimization Framework (OOF).
-
-The use case is a multi-releases effort initiated in Dublin release.
-This use case began with the implementation of PCI optimization in Casablanca.
-In Dublin release, the SON-Handler MS was onboarded as a
-micro-service in DCAE. Enhancements were made to Policy and SDN-C components.
-
-In Frankfurt release, the following are the main enhancements:
-
-- Introduction of Control Loop Coordination functionality, wherein a second control loop execution is
- denied by Policy component when another control loop is in progress.
-- Introduction of adaptive SON, wherein a set of cells whose PCI values are fixed (i.e., cannot be changed
- during PCI optimization) are considered during the PCI optimization.
-- In addition, the first step towards O-RAN alignment is being taken with SDN-C (R) being able to receive a DMaaP
- message containing configuration updates (which would be triggered when a neighbor-list-change occurs in the RAN
- and is communicated to ONAP over VES). `Details of this implementation <https://wiki.onap.org/display/DW/CM+Notification+Support+in+ONAP>`_
-
-The end-to-end setup for the use case requires a Config DB which stores the cell related details of the RAN.
-This is updated by SDN-C (R), and is accessed by SON-Handler MS and OOF for fetching (e.g., neighbor list, PNF id, etc):
-
-- `The Config DB implementation <https://github.com/onap-oof-pci-poc/sdnc/tree/master/ConfigDB/Dublin>`_
-- `Swagger JSON API documentation <https://github.com/onap-oof-pci-poc/sdnc/blob/master/ConfigDB/Dublin/SDNC_ConfigDB_API_v3.0.0.json>`_
-
-As part of this use case work, a RAN Simulator providing a simulated Radio Access Network
-(RAN) with a number of netconf servers simulating PNF elements has been implemented. The
-functionality of the RAN Simulator includes:
-
-- Generation of neighbor-list-update messages
-- Generation of alarms for PCI collision/confusion and
-- Generation of handover metrics for different neighbor pairs (for the ANR use case).
-
-All above functionality are enabled using a simple UI.

-Additional information are available related to previous releases can be found

-How to Use
-~~~~~~~~~~
-
-The OOF-PCI use case is implemented in the Rutgers University (Winlab) ONAP Wireless Lab (OWL).
-For details, please see
-`lab details <https://wiki.onap.org/pages/viewpage.action?pageId=45298557>`_.
-
-This page includes instructions for access to the lab. Setup and testing is done manually up to now.
-
-For all instructions about installing the components, please see:

-Test Status and Plans
-~~~~~~~~~~~~~~~~~~~~~
-
-OOF was enhanced with handling cells with fixed PCI values during the optimization,
-SON-Handler MS was functionally enhanced for adaptive SON functionality, SDN-C (R)
-was enhanced to include handling of DMaaP message for config changes in the RAN,
-and Policy was also enhanced with Control Loop Co-ordination function.
-
-See `test plans <https://wiki.onap.org/display/DW/Testing>`_ for details.
-
-Known Issues and Resolutions
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-(a) It is intended to have the RAN Simulator support sufficient Honeycomb netconf server instances to simulate 2000 cells.
- However, this number may be lower if there are hardware limitations.
-(b) For Control Loop Co-ordination, the denial of a second Control Loop based on Target Lock (i.e., when a second Control
- Loop tries to operate on the same target (in this case, a PNF) is successfully tested. The CLC is also applied at Control
- Loop level only. However, some code updates are required in Policy to properly update the Operations History DB entry, and
- to check the existence of active Control Loops by Policy. This will be addressed in Guilin release, and tracked via
- https://jira.onap.org/browse/POLICY-2581 and https://jira.onap.org/browse/POLICY-2583.
-(c) For Adaptive SON, the functionality in SON-Handler and OOF is implemented, however the OOF functionality is not
- fully tested (this was anyhow a stretch goal). Further, the DCAE-CL-RSP message is not sent by Policy in Frankfurt release.
- This is tracked via https://jira.onap.org/browse/POLICY-2580 and shall be part of Guilin release.
