TS 26.114 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.
