Abstract
Official abstract text for this publication.
In a multi flow HSDPA system comprising a RNC ( 402 ) and a plurality of NodeB's ( 404, 406 ), the present disclosure includes (re-) use of original active queue management, AQM, based congestion control, ABCC for a primary link ( 421 ). For every detected congestion, an end-user IP packet is destroyed. ABCC is not used for the secondary link ( 422 ), which means that application level TCP will not be informed about congestion on the secondary link ( 422 ). The radio link control, RLC, protocol data units, PDU, ( 432 ) are distributed among links based on the congestion status of the links. If secondary link ( 422 ) is congested then more packets will be transmitted on the primary link ( 421 ). This makes it possible to use TCP compatible congestion control for multi flow HSDPA, without the drawback that would result from TCP reacting unnecessarily on flow bitrate decrease.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in a radio network controller configured for high speed downlink packet access (HSDPA) multipoint transmission wherein a received flow of data units is transmitted to a user equipment via a primary communication link and a secondary communication link, said primary and secondary communication links comprising a first radio base station and a second radio base station, respectively, and wherein the transmission of the data units is distributed b…
