摘要： The invention relates to method and device for improving the link configuration speed of high-latency links, such as circuit switched links or satellite links, that use chatty protocols, which require sequential configuration phases, such as standard PPP in accordance with RfC 1661. In the initial link configuration phase, a standard LCP packet is sent out, followed by at least one masked packet that will be discarded silently by a peer operating in accordance with the standard protocol, but whose contents will be processed by a peer operating in accordance with the invention. The initial standard LCP packet produces compatibility with the standard protocol, whereas the sending of masked packets containing configuration information (PAP, CHAP, ICPC, etc.) allows two peers operating in accordance with the invention to accomplish the configuration phases in parallel, such that a link can be configured and ready to transmit network level packets, such as IP packets, much more quickly than with the standard protocol, such as PPP.

摘要： A method and apparatus for improving the data transfer rate of packet-switched networks that employ retransmission timers is disclosed. Upon receipt by a sender of an acknowledgment message indicating that the intended recipient received a data packet, a retransmission timer is initialized with a value that compensates for the time lag between the transmission of a data packet by the sender and the receipt of an acknowledgment message. A communication network includes data transfer terminals that, upon receipt by a sender of an acknowledgment message indicating that the intended recipient received a data packet, initialize a retransmission timer with a value that compensates for the time lag between the transmission of a data packet by the sender and the receipt of an acknowledgment message.

摘要： Communication method and system for transmitting data partitioned into a plurality of data packets between at least two communication units (CU1, CU2, CU4) using a communication network (N). During temporary interruptions of transmission of data packets via the communication network some of the transmitted data packets are lost. The invention allows to avoid the loss of data packets due to temporary interruptions of the communication network by determining at the sending data processing device, based on information received from the communication network, which data packets are lost or will be lost during transmission due to a temporary interruption of the communication network. The method can be used for data transmission via mobile communication networks and an "Internet". To allow a retrieval of lost data packets, data packets scheduled for transmission can be temporarily stored in a temporary storage devices. Transmission of packets, retransmission and other services needed for data communication can be performed by an appropriately modified TCP/IP protocol set.

摘要： A device and method are proposed in which the sender divides an amount of data to be sent into one or more data units and the receiver acknowledges the correct receipt of data units by returning acknowledgement data units to said sender . The data units are sent by said sender in accordance with a flow control procedure th at involves one or more adaptive parameters. After a given data unit is sent, the sender performs a data loss detection routine, and if a triggering event occurs, a correspondi ng response procedure is conducted, where this response procedure comprises at least two different modes for adapting said one or more adaptive parameters. Preferably, there i s a first and a second mode, where the first mode is associated with the actual loss of a data unit, so that this first mode comprises the conventional data loss procedures, and where the second mode is associated with the recognition that an excessive delay has taken place and not a loss of unit.

摘要： The invention relates to a method and a device for improving the processing time of received data in packet oriented applications during a transmission via communication networks, in particular via an IP network and a mobile communication network such as the Global System for Mobile Communication (GSM), Universal Mobile Telecommunication System (UMTS) or General Packet Radio Service (GPRS). The received data packets of the second protocol layer , for instance, the RLP frames, are combined to form data packets of the first protocol layer, for instance to PPP frames, directly by the receiver in the second protocol layer. The completely and correctly combined data packets ar e then released to the first protocol layer. During the release of the data packets to the first protocol layer, a difference is made between two modes. The intra-flow mode is a mode, wherein all completely generated data packets are released, i.e. independent from whether the data packets belong to the same or to two different data flows. In contrast thereto, a difference is ma de in view of the inter-flow mode. In said mode only the completely generated data packets belonging to different data flows are released to the first protocol layer.

摘要： A communication device and method is provided, for which, when having implementations of first protocol that specifies different reliability level s for sending PDUs of a second protocol, where the second protocol specifies segmentation of PDUs of a third, higher layer protocol, a capability is introduced for setting the reliability level of second protocol (L2_ARQ) PDU s differently for second protocol PDUs belonging to a defined data structure containing such second protocol (L2_ARQ) data units. The defined data structure can be a higher layer protocol data unit or the send window. There by the delay caused by retransmission of second protocol data units can be reduced significantly.

摘要： In the present invention, the implementation of a protocol that embeds packe ts is made sensitive to the type of data being embedde, so that adjustable parameters can be set automatically at the layer providing the parameters being adjusted in accordance with the packets being embedded. Thus it is tak en into account that the data in packets being received from a higher layer in order to be encapsulated or segmented and sent further (either directly into the link or on to lower layer), may be classified into different categories with respect to the adjustable parameters, where the parameters can automatically be adjusted for an individual packet in accordance with the category into which is classified.
