摘要： The invention relates to management of data packets and buffers comprising segments of data packets in a mobile communication system (1). Information associated with data packet segments is analyzed by a Base Station System (BSS) (100) housing a data buffer (120). Based on this information analysis, the BSS (100) can identify those segments (P(FIRST)-P(LAST)) in the buffer (120) that constitutes a complete data packet. Once identified, the segments can be discarded from the buffer (120). The information can include size information (S(k), S(k+1)), whereby the analysis comprises pairwise comparing the size (S(k)) of a current segment (P(k)) with the size (S(k+l)) of a next consecutive segment (P(k+l)). This size comparison enables identification of a first segment (P(FIRST)) and a last segment (P(LAST)) 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.

摘要： A method is described for controlling the conformance of a data flow in a communication system to a traffic definition. The communication system comprises a transmitter and a receiver and data packets transporting the data flow are sent from the transmitter to the receiver. The receiver sends responses identifying received data packets to the transmitter, and the transmitter comprises a control function which controls the number of sent data packets for which no response is received according to a limit for the number of outstanding data packets. A conditioning criterion is obtained for the data flow, the conditioning criterion being associated with the traffic definition. The receiver determines a conformance parameter for the received data packets transporting the data flow. The limit and/or the sending of the responses is modified according to the conditioning criterion and the determined conformance parameter for controlling the number of transmitted data packets.

摘要： A method of controlling a data unit sender is described. A flow control procedure for controlling the flow of data units sent by said data unit sender is conducted in dependence on acknowledgement messages from the receiver The flow control procedure utilizes (S103) at least one output limiting parameter (olp; cwnd) for placing a limit on the data units sender's current data send rate. A procedure is provided for detecting (S110) a data unit loss indication, in response to the detection of a data unit loss indication, performing (S311) a retransmission, subsequent to said retransmission (S311) waiting (S312) for an acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost, and distinguishing (S317) whether said acceptable acknowledgment message relates to an original transmission, and in response to distinguishing that said acceptable acknowledgment message does not relate to said original transmission, performing (S318) a congestion response step, while in response to distinguishing that said acceptable acknowledgment message relates to said original transmission, said output limiting parameter is adapted (S319) based on one or more duplicate acknowledgment messages received since receiving the last acceptable acknowledgment message that precedes the acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost.

摘要： A system and method are provided for managing a queue of packets transmitted from a sender to a receiver across a communications network. The sender has a plurality of sender states and a queue manager situated in between the sender and receiver may have a corresponding plurality of queue manager states. The queue manager has one or more queue management parameters which may have distinct predetermined values for each of the queue manager states. When the queue manager detects an event that is; indicative of a change in the sender's state, the queue manager may change its sn tate correspondingly.

摘要： A method (600) for use in a wireless communications system (100) in which there is at least a first node (110) which controls the traffic to and from user terminals (130, 140) in a cell (120) within the system, so that there is downlink traffic in the system. The first node (110) transmits downlink traffic in radio frames, each of which comprises sub-frames. The first node (110) performs measurements on pre-defined system indicators in at least said first cell (120), and based on the results of said measurements, the first node is allowed to autonomously decide (615) to vary the number of available down link sub-frames used for down link traffic in said down link radio frames and also to vary (620) the content of the down link sub frames which are used, said decision being valid (625) for a time which is specified by the first node (110).
