name: DU
full_form: Distributed Unit
context: When an IAB-node accesses to the current IAB-topology, the IAB-donor need to learn the parent of the new IAB-node and discover the topology. There are two potential options as specified in TR 38.874 [2]. Option 1: The DU includes into an F1-AP message an identifier of the collocated IAB-UE. This may, for instance, be a TNL or RNL identifier. The identifier may have been assigned by the CU-CP to the IAB-UE before. Option 2: The IAB-UE includes into an RRC message an identifier for the collocated DU. This identifier may have been assigned by the CU-CP to the DU before. The integration of an IAB-node to the topology may trigger the topology adaptation. The IAB-topology can be changed to provide coverage and ensure service continuity. Based on the information such as backhaul link quality, link- and node-load, neighbour-node signal strength, the new topology is determined. 5.1.1.2 Security Threat In case the identifier of collocated IAB-UE or DU for topology discovery lack confidentiality,
description: The Distributed Unit (DU) is a network function that plays a crucial role in the integration of an Integrated Access and Backhaul (IAB) node into the IAB topology. It interacts with other network functions, such as the Centralized Unit-Control Plane (CU-CP), to facilitate topology discovery and adaptation.
explanation: The context describes the DU's responsibilities within the IAB network, including interaction with other network functions for topology management. These actions are characteristic of a Network Function.
