define media handling and interaction for the Multimedia Telephony Service for IMS (MTSI) including
mechanisms for the negotiation of bandwidth using the SDP bandwidth modifiers. The present study investigates
potential improvements for the end-to-end QoS handling with the purpose to improve the network resource allocation
for variable bit-rate codecs, rate-adaptive codecs and asymmetric sessions (i.e. different bitrates for different directions).
The study will focus on SDP extensions and the interaction with the policy control.
