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

For more information, see the GTPU Path Failure chapter.
