How it Works
This section describes how this feature works.
The cnSGW-C uses the app-infra feature for SBA overload control to throttle the incoming messages.
The system takes appropriate action for the incoming messages that are based on the interface-level threshold configuration. The incoming messages get added to different queues and they are processed based on the message-level priority configuration.
For more information on Overload Support, see the SMF Overload Support chapter, in the UCC 5G Session Management Function Configuration and Administration Guide.
You can exclude session reports for emergency call, voice calls, and empty calls from throttling.
To exclude these session reports, configure the ddn delay-exclude-arplist configuration in profile sgw. If the session report is received for one of the configured ARPs, the cnSGW-C omits that session report from the session report throttling.
