Abstract
For implementing handling of congestions in a mobile network, a base station (100), e.g., an evolved Node B, is provided with at least one congestion controller (400, 400′). The congestion controller (400, 400′) operates in relation to data packets which are received from a transport network. The base station (100) then transmits the data packets on at least one radio link, which may be accomplished by using one or more scheduling queues (402) and a radio interface scheduler (410). A bitrate detector (404) measures a bitrate of the received data packets, and a bitrate limit calculator (408) calculates, on the basis of the measured bitrate, a maximum bitrate for transmission of the data packets on the radio link. A congestion detector (406) is used to detect a congestion in the transport network. In response to the detected congestion, the radio interface scheduler (410) schedules transmissions on the at least one radio link to meet the calculated maximum bitrate.
