Abstract: A method is described for associating a data packet (DP) with a packet bearer (PB) in a user equipment (UE1) of a communication network. The data packet is sent in a data flow from an application function of the user equipment, the packet bearer (PB) is established with the user equipment to transmit the data packet (DP) over the communication network towards a further entity, and the user equipment is adapted to establish different packet bearers. The method comprises the steps of identifying the flow with the data packet in a control entity of the communication network, determining the packet bearer for association with said flow from the different packet bearers in a policy function of the control entity, determining a routing level identification of the further entity, instructing the user equipment to install a packet filter based on the routing level identification, wherein the packet filter associates data packets comprising the routing level identification of the further entity with the determined packet bearer, providing the routing level identification to the application function, including the routing level identification into the data packet, and forwarding the data packet (DP) on the determined packet bearer (PB). A corresponding network, control entity, monitoring entity and computer program are also described.

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.

Abstract: Un método para asociar un paquete de datos (DP) con un portador de paquetes (PB) en un equipo de usuario (UE 1) de una red de comunicaciones, donde el equipo de usuario envía el paquete de datos en un flujo de datos desde una función de aplicación, y comprende medios para establecer que el portador de paquetes (PB) transmita el paquete de datos (DP) sobre la red de comunicaciones hacia una entidad adicional, y donde el equipo de usuario está adaptado para establecer distintos portadores de paquetes, comprendiendo el método lo pasos de recibir una instrucción por el equipo de usuario desde la red de comunicaciones, para instalar un filtro de paquetes basándose en una identificación del nivel de encaminamiento de la entidad adicional, donde el filtro de paquetes asocia los paquetes de datos del flujo que comprenden la identificación del nivel de encaminamiento de la entidad adicional, con un determinado portador de paquetes de los diferentes portadores de paquetes, proporcionar la identificación del nivel de encaminamiento a la función de la aplicación, incluir la identificación del nivel de encaminamiento en el paquete de datos, y reenviar el paquete de datos (DP) sobre el portador de paquetes (PB) determinado.

Abstract: The invention discloses a method (1100) for a cellular wireless access TDD system (100) with a base stations (120, 220) for respective cells (110, 210) in the system, where each cell can accommodate at least a first user terminal (130, 230). The user terminals can receive traffic from their base stations during a down link period, and can transmit traffic to their base stations (120, 220) during an up link period (UL). There is a first guard period (TDu) at the transition from down link to up link, and a second guard period (TUD) at the transition from up link to down link. The method comprises measuring the interference level in a second plurality (110, 210) of cells during part of the time between two consecutive down link periods, and varying the duration of said first and/or second guard period in said second plurality of cells (110, 210) according to the interference level.
