DESCRIPTION
SON (Self-Organizing Networks) functionality is an essential part of existing 4G mobility networks, and will be even more critical for 5G. SON enables automation to improve network performance and efficiency, improve user experience, and reduce operational expenses and complexity. The objective of the OOF-SON (new name for OOF-PCI) use case is to develop an ONAP-based SON platform using the ONAP Optimization Framework (OOF). We have taken a phased approach since SON is complex, and SON for 5G is still evolving. We started with the Physical Cell Identity (PCI) optimization SON use case in Casablanca, then added some centralized Automated Neighbor Relations (ANR) aspects in Dublin. For Frankfurt, we will address gaps such as PCI assignment during new cell addition, alignment with RAN inventory, etc., In addition, we aim to have enhancements such as: additional optimization functionality (e.g. include the use of AI/ML), use of control loop co-ordination in Policy, and alignment with industry trends for open interfaces and open models for the RAN interactions.
The diagram shows the basic flow of ONAP SON.
