context: This solution addresses Key issue #2: Authorization of selection of participant NWDAF instances in the Federated Learning group. As per KI#2, both server NWDAF and client NWDAF need to be authorized for FL procedure. - A server NWDAF needs to be authorized to include a client NWDAF into a Federated Learning group. - A client NWDAF needs to be authorized to join a Federated Learning group. For initiation of FL procedure or reselection of FL client(s) into a FL procedure, the server NWDAF triggers discovery and selection of NWDAF(s) and sends FL request to the client NWDAF. - At the client NWDAF side, authorization of the server NWDAF that it can include the client NWDAF into the FL group can be achieved by reusing existing SBA token-based authorization upon receiving FL request. - At the server NWDAF side, authorization of the client NWDAF to be included into a FL group is implicitly achieved as the server NWDAF only triggers the selection of FL client(s) into the FL group that it
description: The Network Data Analytics Function (NWDAF) is responsible for collecting and analyzing data from various network functions to support federated learning procedures. It plays a crucial role in authorizing the selection of participant NWDAF instances in the Federated Learning group.
explanation: NWDAF is classified as a Network Function because it manages and analyzes network data, and participates in authorization processes for federated learning within the network.
