A method of throttling a media stream, comprising a sequence of media segments, for transmission to a client via a radio access network is provided. The method comprises acquiring a media segment, determining a duration of the media segment, transmitting a first part (501′-504′) of the media segment to the client, and transmitting a remaining part (501″-504″) of the media segment to the client. At least one of the parts (501′-504′, 501″-504″) is transmitted during a time interval (Δt1, Δt2) which is shorter than a corresponding duration of that part, and transmitting the remaining part is delayed (Δt0), such that a time interval (Δttx) between starting transmitting the first part and transmission of the remaining part being completed is shorter than the duration (Δtp) of the media segment. Further, a corresponding network node for throttling a media stream is provided. Embodiments of the invention are advantageous in that bursty traffic is generated, resulting in a more efficient usage of air interface resources and reduced power consumption.
