Due to the lack of support in mobility and quality of service, today's IF-based networks have some inherent limitations: for delivering multimedia services in a mobile environment. In the past few years, these issues have been addressed in the research community and the resulting techniques: are being standardised. However, these development have been done in isolation and become incompatible with each other. In addition to these technical issues, the future infrastructure for charging and accounting mobile multimedia services is expected to be increasingly complicated. In this paper we present a home-proxy based framework which can facilitate the integration of mobility support and QoS management. Furthermore, it enables centralised accounting, which simplifies the cost recovery processes of roaming services. To prove the viability of our design, we hale built and tested this framework on a DiffServ wide-area backbone using an MP3 streaming application. Web of Science
