UMTS, the successor of GSM, is evolving toward a
future wireless all-IP network. In this paper we present how it
supports real-time IP multimedia services, as these services are
expected to drive the adoption of wireless all-IP networks. The
scheme of real time streaming video is one of the newcomers in
wireless data communication and in particular in UMTS, raising
a number of novel requirements in both telecommunication and
data communication systems. This scheme applies when the
mobile user is experiencing real time multimedia content. In this
paper, we describe the design and the implementation of a
decision feedback scheme, which is based on real time protocols
and it is used for streaming video over UMTS transport
channels. The decision feedback scheme uses a friendly, to the
mobile users, congestion control mechanism to control the
transmission rate of the real time video sequence. Furthermore,
we evaluate this mechanism through a number of experiments.
During these experiments we demonstrate the friendly behavior
of the decision feedback scheme to TCP and UDP data streams
that coexist in the same channel with the video sequence.
