摘要： The present invention provides a congestion control method and apparatus, and a related device, to identify congestion in advance and avoid congestion. The method in the present invention may include: obtaining a transmission rate of a transmission link, and obtaining a congestion control window size of the transmission link; calculating a congestion risk coefficient of the transmission link based on the transmission rate and the congestion control window size; and determining whether the congestion risk coefficient is not less than a preset threshold, and if the congestion risk coefficient is not less than the preset threshold, triggering an adjustment to the congestion control window size.

摘要： Embodiments provide an apparatus, a base station transceiver, a mobile station transceiver, methods, and computer programs for configuring a delay for a transmission cycle. The apparatus 10 is operable to configure a delay for a transmission cycle. A transmission cycle corresponds to a process of transmitting a payload data packet from a transmitter 20 and receiving an associated acknowledgement packet from a receiver 30 at the transmitter 20. The apparatus 10 is operable to provide information on the delay between the transmitting of the payload data packet and the receiving of the associated acknowledgement packet to the transmitter 20 and to the receiver 30.

摘要： Embodiments of the present invention disclose a method and an apparatus for sending a Transmission Control Protocol TCP data packet and a system. The sending method includes: obtaining a first round-trip time of sending a TCP data packet in a network, and determining a second round-trip time; if the first round-trip time is longer than the second round-trip time, using a congestion window determined according to a first algorithm as a first congestion window; or if the first round-trip time is shorter than or equal to the second round-trip time, using a congestion window determined according to a second algorithm as the first congestion window; and sending the TCP data packet by using the first congestion window. In the technical solution disclosed in the present invention, a current congestion window that exists when a first round-trip time is obtained grows to a first congestion window at one go, so that a requirement of a service for a throughput can be better met, and a network bandwidth can be utilized more effectively.

摘要： Real-time media or multimedia services in 3GPP GSM/EDGE-compliant mobile radio networks call for reducing the actual latency of transmissions. Resources are assigned by the network to set up or reconfigure a TBF associated to the uplink/downlink transmission of radio blocks from/to an MS. A 5-bit "Coding" field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signalling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, avail of standard window sizes for MSs with multislot capability, as reported in 3GPP TS 44.060, V7.3.0 (2006-01), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g. media or multimedia real-time transmissions, avail of new window sizes with scaled down values remapped to start from 1 to (maximum) 64 RLC/MAC blocks. The scaling bit is asserted or negated by BSC accordingly. Both peer entities comprised in a TBF are receiving the RLC/MAC messages with the proper setting of the scaling bit and the 5-bit coding IF; these entities decode the scaling bit and behave accordingly. The behaviour consists of either assuming the standard window size or scaled window size addressed by the same predetermined 5-bit "coding" information element (fig.3).
