Abstract:
1. A method of alleviating transport network congestion on a flow-controlled backhaul connection of a wireless communications network node, wherein the method comprises: a network node controlling an aggregate bit rate of uplink traffic from a plurality of users supported by the network node, wherein the network node controls the bit rate of uplink traffic from each user based on making uplink grants to the user according to a defined grant table; the network node receiving flow control signaling in cases of transport network congestion on a flow-controlled backhaul connection, said flow control signaling indicating a desired fractional reduction in the aggregate bit rate of uplink traffic from the plurality of users; and the network node setting an effective uplink bit rate for a time period for one or more first users in the plurality of users based on the desired fractional reduction in the aggregate bit rate, wherein the effective uplink bit rate is not directly obtainable from the defined grant table for each first user, and wherein setting the effective uplink bit rate comprises the network node making a plurality of uplink grants over the time period using two or more uplink bit rates selected from the defined grant table for each first user.
