To control a TCP congestion window size for data sent from a TCP sending node in a communications network towards a TCP receiving node via a Radio Access Network, the TCP sending node determines a minimum required bit rate for a data stream sent towards the TCP receiving node. It then determines that a sending bit rate of the data stream must be reduced using a TCP congestion avoidance mechanism. When the congestion avoidance mechanism is applied, the congestion window size is adjusted such that the sending bit rate is no lower than the minimum required bit rate.

Controlling a transmission control protocol congestion window size

A method is provided for a base station set (NODE B) adapted for RLC and MAC-hs signaling in acknowledged mode (AM), the base station set at least forwarding protocol data units (MAC-d PDU) from a Radio Network controller (RNC) to a user entity (UE), the method comprising the steps of monitoring () the MAC layer of the transmission entity of the base station set (), if a MAC discard has occurred in the MAC layer (), that is, protocol data units (PDU's) have been deleted in the input buffer of the base station set (NODE B), transmitting () a discard notification message from the MAC transmission entity in the base station set to the RLC layer of the radio network controller (RNC), indicative of the discarding of protocol data units. There is moreover provided a method for a radio network controller (RNC) adapted for RLC and MAC-hs signaling in acknowledged mode (AM) and a method for a user entity (UE) adapted for RLC and MAC-hs signaling.

Medium access control discard notification

A method and an arrangement in which the assemblies or assembly parts like fiber lengths, opto- and optoelectronic components are transferred between processing modules (). The assembly parts () including a fiber length () are arranged on a pallet means (), which is transferred on a track () between the different processing modules. A free end () of the optical fiber length is picked up by a robot device () and is processed at one of the processing modules. Finally, the robot device holding the fiber end and the pallet means are transferred to another processing module in a common sequence.
