Section: 6.3.21 MFAF discovery and selection
Content: Multiple instances of MFAF may be deployed in a network. The MFAF selection function is supported by the DCCF. The DCCF shall utilize the NRF to discover MFAF instance(s) unless MFAF information is available by other means, e.g. locally configured on the DCCF. The MFAF selection function in the DCCF selects a MFAF instance based on the available MFAF instances. The following factors may be considered by the DCCF for MFAF selection: - S-NSSAI; - NF Types of the Data Sources handled by the MFAF; - NF Set IDs of the Data Sources handled by the MFAF; - MFAF Serving Area information, i.e. list of TAIs for which the MFAF may receive data from Data Sources.
