Abstract:
A method for congestion management in a radio access network is provided. The radio network controller maintains available bandwidth information for each of the downstream links towards the base stations. The radio network controller also measures incoming traffic for each such link and for various traffic classes and uses the traffic measurements and available bandwidth to predict congestion conditions. Upon detecting a congestion condition, congestion avoidance mechanisms such as controlled discard and back-pressure are activated.
