Feature Description
This section explains the behavior of SMF when the dedicated bearer procedure does not end within a defined procedure timeout value. The timeout is termed Service Level Agreement (SLA) timer. The SLA timeout defined at procedure level is known as procedure SLA timer.
While processing the dedicated bearer procedure, the SMF interacts with the peer NFs. The peer NFs can be one of the following:
-
S-GW
-
PCF
-
CHF
-
UPF
When the SLA timer expires before the completion of dedicated bearer procedure, the graceful clean-up is performed at SMF and peer nodes. This clean-up action is based on the stage at which the dedicated bearer procedure is executing.
