context: Figure 5.4.4.23.2-1 shows the procedure for Inter NG (R)AN handover with Xn interface. Figure 5.4.4.23.2-1: Inter NG (R)AN handover with Xn interface. The procedure for Inter NG (R)AN handover (with Xn interface) is as follows. If the handover is required, the UE sends the Measurement Report to the source NG (R)AN. The source NG (R)AN evaluates the report and makes the handover decision. The source NG (R)AN refreshes the AN keys (derives KAN*). The source NG (R)AN sends the Handover Request(UE Security Capabilities, Handover Restriction List, NSSAI, KAN*) to the target NG (R)AN via the Xn interface. The source NG (R)AN shall include the UE security capabilities and ciphering and integrity algorithms used in the source cell in the handover request message. The target NG (R)AN checks if the NSSAI can be supported or not. If the UE qualifies for accessing the slice via the new NG (R)AN, the target NG (R)AN sends the Handover Request ACK to the source NG (R)AN. The target NG (R)AN, with
description: NG refers to Next Generation network, specifically in the context of 5G networks and handovers between different radio access networks (RANs). It encompasses the architecture and components involved in managing user equipment (UE) connections and mobility across the network.
explanation: The classification as a Network is justified by the context discussing Inter NG (R)AN handover procedures, involving communication between source and target Next Generation RANs via the Xn interface. This highlights NG's role in defining the architecture for next-generation telecommunications networks.
