Abstract

Un aparto, método, procesador(es), y producto de programa de computadora evitan la pérdida de datos de usuario mediante transferencia asistida por equipo de usuario de red controlada en un sistema de comunicación inalámbrica de paquete de datos; un receptor inalámbrico recibe unidades de datos en paquete (PDU) de control de enlace de radio (RLC) desde el equipo de usuario (VE) que está recibiendo servicio por parte de un nodo fuente; un transmisor inalámbrico ordena al UE realizar la transferencia; una interfaz de comunicación de red transmite contexto de enlace ascende.nte (UL) RLC desde el nodo, fuente al nodo objetivo, y transmite el mensaje de inicialización de enlace descendente (DL) RLC y DL RLC PDUEn-tránsito almacenados en memoria intermedia desde el nodo fuente al nodo objetivo.
