Study on Core Network Enhanced Support for Artificial Intelligence (AI) / Machine Learning (ML)
This study will focus on the following objectives:
- AI/ML cross-domain coordination aspects on whether and how to consider 5GC enhancements to LCS to support AI/ML based Positioning considering conclusions of the RAN study in TR 38.843 [6].
NOTE 1: UE data collection, model delivery and transfer to the UE and model identification/management are not within the scope of the study.
NOTE 2: Whether and how the scope could be extended in the future with additional AI/ML cross-domain coordination aspects will be decided based on expected future SA plenary decisions considering the outcome of the related work in the involved RAN WGs(s).
- Whether and what 5GC enhancements are needed to enable 5G system, including the AF, to assist in collaborative AI/ML operations involving NWDAF for Vertical Federated Learning (VFL).
NOTE 3: For Vertical Federated Learning, RAN and UE aspects are out of scope.
- Whether and how to enhance 5GC to support NWDAF-assisted policy & QoS control.
- Whether and how to enhance 5GC to address network abnormal behaviour, i.e. signalling storm, with the assistance of NWDAF.
