摘要： A system and method for specifying the quality of service in a transmission of data packets between a service entity and a user equipment is provided. A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected. A first transmission context, associated with a first set of attributes, is established between a core network node and the user equipment. A second transmission context, associated with a second set of attributes, is established between an access node and the user equipment. The selected service class is specified by a third set of attributes, which is forwarded to the core network node and the access node. The third set of attributes is used to determine the first set of attributes and/or the second set of attributes.

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. In the method, 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. A receiver and a software program embodying the invention are also described.

摘要： New methods and devices for implementing an ARQ mechanism over a multi-hop connection (sender-relay-receiver) are proposed. A communication protocol is described in accordance with which data units are arranged in a sequence and each sent data unit is identifiable by a sequence position identifier. The sender implements a sending peer, the relay a relay peer and the receiver a receiving peer. Feedback messages are exchanged, which using said sequence position identifiers, carry information on a receipt of sent data units. The communication protocol provides for at least a first type and a second type of receipt information, the first type (RACK) of receipt information being indicative of a correct receipt of a data unit at a relay peer of said communication protocol, and the second type (ACK) of receipt information being indicative of a correct receipt of a data unit at a final destination peer of said communication protocol.

摘要： A technique is provided for processing data in a packet-based communications environment. A single data packet is encapsulated into a single link layer packet data unit. The link layer unit is encoded to form at least one code block. After the currently available radio resource capacity during a fixed duration transmission interval has been determined, bits within the code block are selected to fit into or otherwise match the radio resource capacity. Thereafter, the selected bits are transmitted via a physical layer. In some variations, unsolicited redundant sets of bits are transmitted thereafter to facilitate successful receipt.

摘要： Different types of traffic requiring different inactivity timer settings are assigned to different bearers or to different QoS classes. Different inactivity timer settings are established for different traffic types. Individual bearers or individual QoS classes are linked to a corresponding inactivity timer profile. The link may be accomplished in a number of ways. For example, an additional QoS parameter may be employed in a 3GPP QoS profile, or a new QoS class identifier may be mapped to an inactivity timer setting. Different inactivity timer settings allows both UE battery power conservation to be prioritized for some traffic and end-user experience (quick subsequent response times) to be prioritized for other traffic.

摘要： A device and method for controlling data unit communications between a sender and a receiver, and flexibly responding to a potential data loss event. Data to be sent are divided into data units and transmitted from the sender to the receiver. If the receiver fails to receive a data unit, the sender retransmits the data unit using a flow control procedure using adaptive parameters. The sender inserts a mark in each transmitted data unit indicating whether each data unit is an original transmission or a retransmission. For each data unit correctly received, the receiver inserts the corresponding mark in an acknowledgment data unit and sends the acknowledgment to the sender. The sender determines whether the correctly received data unit was an original transmission or a retransmission based on the mark or by comparing the round-trip time for the acknowledged data unit with a predetermined round-trip time for an original transmission.

摘要： A method and device for determining a parameter (RTO) associated with a retransmission time-out feature in a data unit transmitter implementing a protocol (TCP) that provides an acknowledgment feature and a retransmission time-out feature, where according to one aspect decreasing values of the round trip time (RTT) are treated differently with respect to their influence on a mean deviation parameter (RTTVAR) than increasing values of the round trip time, where according to another aspect weight values (g, h, w) used in the determination of the parameter (RTO) are chosen such that at least one of them is time variable, and where according to a further aspect the parameter (RTO) is also calculated on the basis of a value (SR) indicative of the number of spurious time-outs in the communication.
