Architectural enhancements for end-to-end Quality of Service (QoS)
The present document investigates possible solutions to enhance the end-to-end QoS architecture as currently specified in TS 23.207 [4] to achieve improved end-to-end QoS in the case of interworking with IP network domains or backbone networks that provide IP QoS mechanisms and enhanced interworking with other next generation networks. Within this technical report, emerging QoS standardization efforts from TISPAN, ITU-T, and the IETF should be taken into account.
