Abstract: A method for specifying the quality of service in a transmission of data packets between a service entity (AF1) and a user equipment over a mobile network is described. The mobile network comprises a core network node (SGSN1) and an access node (NB1, RNC1) which are adapted to control the handling of data packets sent between the service entity (AF1) and the user equipment (UE1). A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected from said plurality for the transmission. A first transmission context (PDP1) is established between the core network node and the user equipment (UE1), said first transmission context being associated with a first set of attributes for defining a first quality of service for the exchange of the data packets with the user equipment in the transmission. Furthermore, a second transmission context (RAB1, RB1) is established between the access node (NB1, RNC1) and the user equipment (UE1), said second transmission context being associated with a second set of attributes for defining a second quality of service for the exchange of the data packets with the user equipment in the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node. A corresponding mobile network, control device and computer program are also described.

Abstract: A data unit sender and method of controlling a data unit sender are presente d, in which a time-out monitoring procedure implements a first, longer time-out period (SRTO), and a second, shorter time-out period (QRTO), where a retransmission is executed after the shorter time-out period if the availabl e transmission capacity value for unsent data is greater or equal to the size of a designated data unit that is to be retransmitted as a result of said time- out monitoring procedure.

Abstract: Un método para especificar la calidad de servicio en una transmisión de paquetes de datos entre una entidad de servicio (AF1) y un equipo de usuario sobre una red de telefonía móvil que comprende un nodo de red de núcleo (SGSN1) y un nodo de acceso (NB1, RNC1) que está adaptado para controlar el manejo de paquetes de datos enviados entre la entidad de servicio (AF1) y el equipo de usuario (UE1), en el que una pluralidad de clases de servicio que se refieren a la calidad de servicio están preconfiguradas y una clase de servicio seleccionada es seleccionada de la citada pluralidad de clases de servicio para la transmisión, en el que un primer contexto de transmisión (PDP1) es establecido entre el nodo de red de núcleo y el equipo de usuario (UE1), siendo el citado primer contexto de transmisión asociado con un primer conjunto de atributos para definir una primera calidad de servicio para el intercambio de los paquetes de datos con el equipo de usuario en la transmisión, en el que un segundo contexto de transmisión (RAB1, RB1) es establecido entre el nodo de acceso (NB1, RNC1) y el equipo de usuario (UE1), siendo el citado segundo contexto de transmisión asociado con un segundo conjunto de atributos para definir una segunda calidad de servicio para el intercambio de los paquetes de datos con el equipo de usuario en la transmisión, en el que la clase de servicio seleccionada determina el primer conjunto de atributos mediante una primera única función de mapeo llevada a cabo en el nodo de red de núcleo y la clase de servicio seleccionada determina el segundo conjunto de atributos mediante una segunda única función de mapeo llevada a cabo en el nodo de acceso, en el que la clase de servicio seleccionada es especificada mediante un tercer conjunto de atributos que es enviado al menos a uno del nodo de red de núcleo y del nodo de acceso, y en el que las funciones de mapeo primera y/o segunda determinan el primer conjunto de atributos y/o el segundo conjunto de atributos del tercer conjunto de atributos.

Abstract: The technology described relates to management of data packets and buffers comprising segments of data packets in a mobile communication system. Information associated with data packet segments is analyzed by a Base Station System (BSS) housing a data buffer. Based on this information analysis, the BSS can identify those segments in the buffer that constitute a complete data packet. Once identified, the segments can be discarded from the buffer. The information can include size information, whereby the analysis comprises pairwise comparing the size of a current segment with the size of a next consecutive segment. This size comparison enables identification of a first segment and a last segment of the complete data packet. The information could also, or alternatively, include a notification provided in the header of the segment. This notification identifies the associated segment as the first or last segment of the data packet or an intermediate segment.

Abstract: A method of controlling the flow of an amount of data from a sending peer to a receiving peer of a predetermined communication protocol is described. The method comprises dividing the amount of data into a plurality of data segments, where the data segments are ordered in a sequence. The segments are sent to the receiving peer in the order of said sequence. The receiving peer acknowledges the correct receipt of a data segment and identifies the last correctly received data segment of the sequence that was received in the proper order of the sequence. The sending peer is arranged such that if it receives a threshold number of duplicate acknowledgements, it performs a retransmission. The threshold number that trigger a retransmission is an adaptive parameter determined based on the size of a receive window, the size of the receive window representing a number of data segments which can be stored in a buffer space at the receiving peer.
