Failure Handling
The AMF has implemented strategies to handle the following failure scenarios:
-
When the SMSF activation process fails, the AMF sets the SMS Allowed value to false in the Registration Accept message.
-
If the failure is observed during the deactivation or when sending uplink SMS, the AMF does not perform any action.
-
When the SMSF is deactivated, the AMF marks the SMS state as not allowed irrespective of the deactivation result from SMSF.
-
On the incoming response messages, the AMF does not perform any validations, such as when the mandatory IE missing.
Note | The failure handling profile configuration determines the retry and retransmission of messages. For the SMSF failures, the AMF supports only retry and ignore as the failure actions. |
