Executive Summary

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 In Frankfurt, we will address gaps such as PCI assignment during new cell addition, alignment with RAN inventoryaddressed some enhancements such as basic CM-notify handling (as preparation for O-RAN alignment), adaptive SON, etc. , In additionGuilin, we aim to have enhancements such as: additional optimization functionality (e.g. include the introduced 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 interactionsby onboarding an offline-trained ML-model to ONAP which will provide additional inputs to PCI optimization based on historical PM data, and stabilized the functionality in Honolulu. In Istanbul, we will align FM messages with relevant standards, move to new 3GPP NRM-based yang models and leverage CPS for RAN configuration.

Business Impact

SON is an essential feature in mobility networks, and relevant to every operator. Any ONAP-based network deployment for 5G will benefit from an ONAP-based SON solution, which provides a disaggregation of SON functions into modules aligned with the ONAP architecture. Operators and vendors will both benefit from the ability of vendors to bring best-in-class solutions to each module, while leveraging the benefits of a community-supported open platform. This will enable faster development of innovative solutions. The approach taken could very well be evolved to address SON use cases whose scope extends beyond just the RAN.

There are no additional organizational management or sales strategies for this beyond whatever is required for ONAP deployment to support 5G.
