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 data unit sender and method of controlling a data unit sender are presented, 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 available 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 time-out monitoring procedure.

Abstract: A method of controlling a data unit relay device is described, applied to a relay ARQ protocol in accordance with which a source peer sends data units to a destination peer via at least one relay peer. The relay ARQ protocol provides for a first type and second type of receipt information, where the first type is indicative of a correct receipt at a relay peer, and the second type is indicative of a correct receipt at the destination peer. In a data unit relay device that is arranged for deliberately dropping data units of the relay ARQ protocol under one or more predetermined conditions, a procedure is provided for indicating to the source peer and the destination peer that a data unit has been deliberately dropped and for identifying the deliberately dropped data unit, such that the source and destination peer may perform retransmission control for the dropped data unit as if it had been successfully received at the destination peer

Abstract: A method of controlling a transmission of data units arranged in accordance with a predetermined communication protocol over a plurality of network entities, said network entities operating according to said predetermined communication protocol, from a sending network entity to a receiving network entity over one or more forwarding network entities, comprising providing in a data unit a first data field arranged to contain network entity identification information, said first data field being different from a forwarding data field designated by said communication protocol to contain information to be used by forwarding network entities for forwarding said data unit to the receiving network entity, said first data field being defined such that a given network entity that reads the first data field can at least make a decision on the basis thereof whether said given network entity is identified or not, and in said one or more forwarding network entities, performing a data unit processing operation after receiving said data unit, which comprises reading said first data field and making an identification decision on the basis thereof whether the forwarding network entity performing said data unit processing operation is identified or not.
