Feature Description
When UPF detects a GTP-U path failure, it sends Node Report Request (with NodeID and GTPU Peer Information) to cnSGW-C. cnSGW-C clears the PDU sessions belonging to the GTP-U peer and UPF node ID.
This feature supports the following:
-
Sending Node Report Success
-
Cleaning session or bearer based on the reported value in node-report (Node-ID and Peer Information)
-
Incrementing the relevant statistics
