    Abstract: In a packet switched telecommunications networks a dimensioning method, a dimensioning tool and network links dimensioned according to the method and with the help of the tool are provided. The idea behind the embodiments of the invention that, a so called operation point, representing the most representative traffic mix on a link shall be defined to calculate the effective bandwidth of a connection. In accordance with the implementation, the dimensioning method uses an inverted Call Admission Control (CAC) method and Offered Load to calculate effective bandwidths. The effective bandwidths are then used in the Kaufman-Roberts formula for network dimensioning. The inverted CAC method calculates the minimum capacity required to admit a given number of connections from different traffic classes. The operation point of the system is calculated based on the Offered Load and Grade of Service (GoS) requirement. The effective bandwidths are then calculated using the operation point.

    Abstract: A mechanism is provided to resolve the Iub transport network congestion efficiently for HSDPA by dynamic adjustment of the transmit window of the RLC. The RLC protocol is extended with congestion control functionality. The Iub TN and Uu congestion detection method in the Node-B (120) signals the congestion to the RNC (110), and this congestion indication is used by RLC to react on the congestion situation. In the RNC (110), the transmission window of the RLC is adjusted to control the flow rate. When congestion is detected, the RLC transmission window size is decreased. When there is no congestion, then the RLC transmission window size is increased automatically. Different types of congestion are distinguished and are handled in different ways. Alternatively, congestion control is achieved without any modification in the RLC layer from the existing standard. Here, RLC STATUS PDUs are used to change the RLC transmission window size.

    Abstract: A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as 'green' data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum 'green' buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a 'green' data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as 'green' data packets are discarded, so as not to be transported through the transport network.
