Limitations

This feature has the following limitations:

  • If the CDL notifications are lost and the sessions are not cleared, the SMF node manager retries the bulk deletion operation only once after 10 minutes.

  • If the node report request arrives and the system is in overload state, some CDL notifications are dropped. In this case, the SMF performs the session clean-up based on error indication report request from the UPF.

  • The UPF currently sends only one Remote GTP-U peer in the Node Report request. So, the SMF can validate only one remote GTP-U peer.
