Feature Description
The SMF utilizes the NF Failover support to achieve the PCF failover functionality.
The NF Failover feature supports the following functionality:
-
Multiple endpoints for a service as primary and secondary endpoints. The endpoints can be configured using the NRF Client Profile configuration and the NRF Failure Profile configuration.
-
Failure behavior based on:
-
Message Type
-
HTTP Status Codes in the response messages
-
Once the PCSCF profile is configured, the SMF assumes that the PDU activation is for the IMS and IMS requires PCF, then SMF rejects the PDU regardless of the failure handling configuration.
-
The SMF ignores the failure handling configuration and rejects the PDU creation if there is “pcscf-profile” under profile dnn.
-
Operator can’t configure the following parameters under the same “profile dnn”:
-
pcf-interaction false
-
pcscf-profile
-
