    Abstract: Communication method and system for transmitting data partitioned into a plurality of data packets between at least two communication units (CU1, CU2) using a communication network (N). During temporary interruptions of transmission of data packets via the communication network some of the transmitted data packets are lost. The invention allows to avoid the loss of data packets due to temporary interruptions of the communication network by determining at the sending data processing device (CU1, T1), based on information (1M) received from the communication network (N), which data packets are lost or will be lost during transmission due to a temporary interruption of the communication network. The method can be used for data transmission via mobile communication networks and an "Internet". To allow a retrieval of lost data packets, data packets scheduled for transmission can be temporarily stored (S11) in a temporary storage means (S1, S2). Transmission of packets, retransmission and other services needed for data communication can be performed (S12) by an appropriately modified TCP/IP protocol set (T1, T2).

    Abstract translation: 用于使用通信网络（N）在至少两个通信单元（CU1，CU2）之间传输分割成多个数据分组的数据的通信方法和系统。 在通过通信网络暂时中断数据分组传输期间，一些传输的数据分组丢失。 本发明允许基于从通信网络（N）接收的信息（1M）在发送数据处理设备（CU1，T1）处确定通信网络的暂时中断而导致的数据分组丢失，哪些数据分组 由于通信网络的暂时中断而在传输期间丢失或将丢失。 该方法可用于通过移动通信网络和“因特网”进行数据传输。 为了允许检索丢失的数据分组，可以临时存储安排传输的数据分组（S11）到临时存储装置（S1，S2）。 可以通过适当修改的TCP / IP协议集（T1，T2）来执行用于数据通信所需的分组，重传和其他服务的传输（S12）。

    Abstract: Un método ubicado en un nodo de red para adaptar dinámicamente una Plantilla de Flujo de Tráfico (TFT) para controlar el encaminamiento de paquetes de datos de flujo descendente desde el nodo de red a un nodo de usuario, de tal manera que el método comprende las etapas de: recibir un paquete de datos de enlace ascendente enviado por un canal portador preferente desde el nodo de usuario, de tal manera que el portador preferente es un portador especial adaptado para transportar paquetes de datos de tráfico de datos preferente; extraer parámetros del paquete de datos de enlace ascendente, de tal manera que los parámetros comprenden al menos la dirección de destino del paquete de datos de enlace ascendente; y definir un subconjunto de filtros de paquetes de enlace descendente, destinados a filtrar paquetes de datos de enlace descendente en función de los parámetros extraídos, de tal modo que el subconjunto de filtros de 10 paquetes de enlace descendente identifica paquetes de datos de enlace descendente que tienen una dirección de fuente que coincide con la dirección de destino del paquete de datos de enlace ascendente; y modificar la TFT en función del subconjunto de filtros de paquetes de enlace descendente, a fin de encaminar los paquetes de enlace descendente identificados, a través del canal portador preferente, hasta el nodo de usuario, así como para encaminar diferentemente los paquetes de datos de enlace descendente que tienen direcciones de fuente que no coinciden con la dirección de destino del paquete de datos de enlace ascendente.

    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: According to a first aspect, the invention can be embodied as a method of controlling a radio access network entity of a data unit communication network 5 and as a corresponding radio access network entity, said radio access network entity being involved in providing a transport service to a radio terminal of said data unit communication network, said transport service being characterized by a set of values associated with respective service quality parameters, said method comprising monitoring a communication quality at the radio access level of a 10 communication between said terminal and an access point of said radio access network, and setting a congestion indication marking in data units of said transport service if said communication quality fulfils a radio communication degradation condition.

    Abstract: Data packets of a flow associated with a first bearer and data packets of a flow associated with a second bearer are received in an intermediate node (140). The data packets are then transmitted from the intermediate node (140). in response to a congestion being detected on the first bearer, one of the first bearer and the second bearer is selected for notification of the congestion in the associated flow. The selection may be based on a type of the congestion, e.g. the detected congestion being in a transport network (160) or the congestion being on a radio link (250).

    Abstract: Length parameter values (QL,QL a v) of a queue is compared with a corresponding length threshold value (L t h). A congestion notification procedure and an automatic threshold adaptation procedure which adapts length threshold value on the basis of characteristics of a link provided to the queue buffer are performed, if the length parameter value is equal to or greater than the threshold value. Independent claims are included for the following: (1) Queue buffer controlling program; (2) Data carrier storing queue buffer controlling program; and (3) Data unit transmission device.
