Abstract

En una red de comunicación inalámbrica en donde las estaciones de base reciben unidades de datos de protocolo (PDU) de las estaciones móviles para descompresión y descifrado de transferencia secuencial ordenada como unidades de datos de servicio (SDU) a una red de núcleo asociada, las enseñanzas presentadas en la presente proveen un método para soportar traspaso fluido de una estación móvil de una estación de base de fuente a una estación de base blanco. A manera de ejemplo, las enseñanzas aplicadas en la presente a una red basada en las especificaciones E-UTRA, como se promulga por 3GPP. Sin embargo, el ejemplo no es limitante, dado que las enseñanzas aplicadas en la presente a cualquier red que emplea en la distribución de datos de secuencia y detección de datos duplicados en el traspaso. Ampliamente, la estación de base de fuente envía SDU fuera de secuencia y información de número de secuencia correspondiente a la estación de base blanco para soportar traspaso fluido y la estación de base blanco usa la información para solicitar retransmisiones como es necesario para reordenamiento de paquetes.
