Abstract

Un método por un nodo de red, que opera como una CU donante de destino en una red IAB que actúa como un nodo donante candidato para un nodo de IAB en migración y proporciona conectividad para un UE. Se recibe (1701) un mensaje para el traspaso de IAB que incluye los contextos del nodo de IAB en migración y los UEs y los nodos de IAB atendidos directa o indirectamente por el nodo de IAB en migración. Se lleva a cabo el control de admisión (1703) para los UEs y nodos de IAB. Se prepara (1705) un comando de traspaso a una terminación móvil, MT, del nodo de IAB en migración, y cada UE y MT de los nodos de IAB. Se genera (1707) un comando de traspaso de grupo que contiene recursivamente los comandos de traspaso de todos los UEs y MTs. Se envía (1709) un mensaje de confirmación de traspaso que incluye una lista de recursos de sesión de PDU admitidos y no admitidos y que contiene el comando de traspaso de grupo. Se recibe un mensaje de Reconfiguración de RRC completa (1711).
