Designing a wireless broadband IP system with QoS guarantees

The growth of the Internet community and the trend towards multimedia services changes the
Internet Protocol (IP) suite. Simultaneously, users desire to have a high speed wireless access to the Internet. To meet the increased service and mobility needs the traditional IP protocol has been
enhanced with advanced mobility and Quality of Service (QoS) features. This paper proposes a concept
which seamlessly integrates these modern IP techniques with wireless broadband radio access
technology. The defined wireless IPv6 based radio access network supports real-time applications in
mobile IP environment utilising specific radio flows for QoS management. The ACTS WAND wireless
ATM access system was considered as a starting reference point which was extended to provide efficient native IP support. The depicted system architecture covers the mobile terminal, radio access network and the necessary interworking functions.
