- store the assoc ID of a UE at the RRC - if F1 receives an SCTP shutdown, it removes the endpoint - F1 will also send an "F1 Lost Connection" message to the RRC - it is not yet possible to reconnect a DU after it had already been connected at the CU, since the CU F1AP task will try to rebind GTP, which fails
