Abstract

Un sistema de comunicaciones en paquete de datos emplea cifrado de datos en un protocolo de convergencia de datos en paquetes (PDCP) y un control de radio-enlace (RLC) en la capa 2 de la transmisión entre un transmisor (TX) y un receptor (RX). Se utiliza un número único de secuencia tanto para el PDCP como para el RLC para reducir costos adicionales mediante la señalización de un primer número de secuencia para cifrado del PDCP en un TX hacia el RX antes de la comunicación en paquete de datos cifrados. Un número de secuencia acompaña a cada PDU del RLC, que puede abarcar unidades de datos de servicio (SDU) concatenadas o segmentadas desde el PDCP en capa superior. Este número de secuencia es suficiente para que el RLC realice el reordenamiento, la detección de separaciones, la retransmisión, etc., mientras que también permita que el PDCP en capa superior del RX reconstruya un valor secuenciado utilizado para descifrar contenidos.
