|abstract: ||This article presents a ﬁeld evaluation of an IP-based architecture for heterogeneous environments that has been developed
under the aegis of the Moby Dick project, covering UMTS-like (universal mobile telecommunications system) TD-CDMA (time
division-code division multiple access) wireless access technology, wireless and wired LANs. The architecture treats all transmission capabilities as basic physical and data-link layers, and replaces all
higher-level tasks by IP-based strategies. The Moby Dick architecture incorporates mobile IPv6, fast handovers, AAA-control (authentication, authorisation, accounting), charging, and quality of service (QoS) in an integrated framework. The architecture further allows for optimised control on the radio link layer resources.
It has been implemented and tested by expert users, and evaluated by real users on ﬁeld trials with multiple services available.|
