    Abstract: A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronisation that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.

    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 comprise 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: A system and method for configuring a Traffic Flow Template, TFT, in real time. The present invention dynamically adapts the TFT to control the routing of downlink data packets from a GGSN to an MS. When the MS sends an uplink data packet on a premium bearer channel, a TFT controller extracts from the uplink data packet, parameters which include at least the destination address of the uplink data packet. A downlink packet filter subset for filtering downlink data packets is then defined as a function of the extracted parameters. For example, the downlink packet filter subset may identify downlink data packets having a source address that matches the destination address of the uplink data packet. The TFT is then modified as a function of the downlink packet filter subset to route the identified downlink packets through the premium bearer channel to the MS, and to route differently, downlink data packets having source addresses that do not match the destination address of the uplink data packet.

    Abstract: The invention relates to retransmissions in wireless communication systems. It is proposed to reduce the retransmission delays by utilizing feedback associated with a lower protocol layer than the conventional feedback messages of the ARQ functionality. After sending a packet from a transmitter towards a receiver, the transmitter monitors the link for a low-level control signal from the receiver. The low-level control information can e.g. comprise power control commands or be related to link quality indicators. Based on this signal, it is decided whether a retransmission is to take place, e.g. at the transmitter or at an external control unit.

    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.
