Abstract: Flow statistics for a buffer that receives data from a plurality of other entities are collected, and an available bandwidth for an interface coupled to an output side of the buffer is determined. From those is determined an arrival rate such that the buffer would not be overloaded. A flow control message is sent to each of the entities that limits aggregate flow from the entities so as not to exceed the arrival rate. One embodiment uses a scaling factor in the flow control messages, the same scaling factor for each entity on any given scheduling interval. An entity receives the flow control message and from it determines an allowed amount CRallowed of packet data units PDUs for that scheduling interval. The lower of CRallowed and an allocation of granted credits CR is used to compute a send rate, which the entity uses as its maximum rate for the interval.

Abstract: A data transport method in a telecommunications system is provided. The method comprises creating a traffic channel connection between two network elements in the telecommunications system, allocating data of a number of user entities for transportation over the virtual channel using overbooking, buffering data packets into separate buffers, according to the priority level of the packets, to wait for transport over the traffic channel, and multiplexing the data packets with determined priority levels into the virtual channel according to the priority level of the packets such that whenever higher priority level data packets are available, the higher priority level data packets are multiplexed into the virtual channel before lower priority level data packets. Additionally, formation of user data packets is controlled according to a filling degree of at least one of the buffers.

Abstract: Data transport methods, a radio network controller, a network element, and a computer program are provided. The method includes: forming a transport channel data stream from at least a portion of a logical channel data stream; forming a high-speed downlink packet access data stream from at least a portion of a logical channel data stream; and multiplexing at least a portion of the transport channel data stream and at least a portion of the high-speed downlink packet access data stream into a virtual channel.
