AMF as NF Consumer
The AMF as an NF consumer uses multiple services offered by the peer NFs.
The following scenarios are processed for a successful communication to be established:
-
The AMF as a consumer looking for OAuth2-enabled profiles from NRF, must enable the AccessToken that is required in each profile nf-client nf-type configuration.
-
The AMF as a consumer communicates with any of the applicable nf-types , such as AMF, PCF, UDM, AUSF, SMF, and SMSF.
-
The AMF as a consumer sends the Nnrf_AccessToken request to the NRF server based on the nf-client configuration.
-
The AMF as a consumer sends a request with an AccessToken to nf-producer . If it gets rejected due to the AccessToken validation failure, then the AMF failure handling template (FHT) handles those responses appropriately.
