How it Works
This section describes how the SMF handles message-level failures and the corresponding HTTP status code-based failures.
The SMF initiates the following messages:
-
PcfSmpolicycontrolCreate
-
PcfSmpolicycontrolUpdate
-
PcfSmpolicycontrolDelete
During the PDU session lifecycle, the SMF exchanges the messages at various stages with the PCF. Depending on the HTTP status code configured in the NRF failure profile, the SMF takes one of the following actions:
-
Ignore
-
Continue
-
Terminate
