full_form: Fully Qualified TEID
context: target parent node IAB-DU. These UL packets belong to the IAB-MTâs own signalling and, optionally, data traffic. 11. The IAB-donor-CU configures BH RLC channels and BAP-sublayer routing entries on the target path between the target parent IAB-node and target IAB-donor-DU as well as DL mappings on the target IAB-donor-DU for the migrating IAB-nodeâs target path. These configurations may be performed at an earlier stage, e.g. immediately after step 3, or before step 3. The IAB-donor-CU may establish additional BH RLC channels to the migrating IAB-MT via RRC message. 12. The F1-C connections are switched to use the migrating IAB-nodeâs new TNL address(es), IAB-donor-CU updates the UL BH information associated to each GTP-tunnel to migrating IAB-node. This step may also update UL FTEID and DL FTEID associated to each GTP-tunnel. All F1-U tunnels are switched to use the migrating IAB-nodeâs new TNL address(es). This step may use non-UE associated signaling in E1 and/or F1 interface to
description: Fully Qualified TEID (FTEID) is a parameter used in the context of Intra-CU topology adaptation procedure in SA, specifically for updating UL BH information associated with each GTP-tunnel and switching F1-U tunnels to use the migrating IAB-node's new TNL address(es).
explanation: The provided text describes FTEID as a parameter used within a specific telecommunications procedure (Intra-CU topology adaptation). This, along with its role in updating tunnel information, classifies it as a Parameter.
