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.
