Abstract

La invención se refiere a un método en un equipo de usuario, UE, para llevar a cabo el traspaso a una célula de destino en una red inalámbrica, en donde el método comprende llevar a cabo (1340) un primer procedimiento de acceso aleatorio, RA, en primeros recursos de RA de la célula de destino, en respuesta a la falla del primer procedimiento de RA, abstenerse (1350) de declarar una falla de enlace de radio, RLF, para la célula de destino y llevar a cabo un segundo procedimiento de RA en segundos recursos de RA de la célula de destino que sean diferentes de los primeros recursos de RA; y declarar (1370) una RLF para la célula de destino con base en una falla del primer procedimiento de RA y una falla del segundo procedimiento de RA, o una expiración de un temporizador antes de completar con éxito el segundo procedimiento de RA; la invención se refiere además a un UE que implementa el método, a un método correspondiente en un nodo de red ya un nodo de red que implementa el método.
