Section: 6.3.20 ADRF discovery and selection
Content: Multiple instances of ADRF may be deployed in a network. The NF consumers shall utilize the NRF to discover ADRF instance(s) unless ADRF information is available by other means, e.g. locally configured on NF consumers. The ADRF selection function in NF consumers selects an ADRF instance based on the available ADRF instances. NOTE: When NF consumer is DCCF, the DCCF can have information available already from previous registrations of ADRFs. In this case, NRF discovery is not needed. The following factors may be considered by the NF consumer for ADRF selection: - S-NSSAI. - ML model storage capability.
