The objective of this TR is to characterise the 3GPP Packet-switched Streaming Service (PSS). In doing so, this TR considers the impacts of the underlying network configurations and how the streaming mechanism itself could be optimised.

The scope of this TR includes consideration of (non-exhaustive):
  • Trade-off between radio usage efficiency and streaming QoS
  • Feedback of network conditions and adaptation of stream and/or the transmission of the stream
  • Optimal packetisation of the media stream in line with the segmentation within the transport mechanism
  • Error robustness mechanisms (such as retransmission)
Client buffering to ease the QoS requirements on the network and enable more flexibility in how the network transport resources are applied.
