Abstract: Various embodiments relate to network repository function apparatus configured to implement an authorization mechanism for a federated learning (FL) training process, including: at least one processor; and at least one memory storing instructions, that when executed by the at least one processor, cause the apparatus at least to: receive from a network data analytics function (NWDAF) NWDAF FL profile data including a FL process role parameter; receive an access token from the FL server for the NWDAF that is the potential FL client; determine if the FL access token request is authorized for the NWDAF based upon the FL profile data; and send an access token for the NWDAF to the FL server when access token request for the NWDAF is authorized.
