Abstract
Systems beyond 3G — using IP to combine 3G, wireless LANs and other access technologies — will offer users much greater flexibility and choice for mobile communications in the medium term. The IST projects BRAIN and MIND have developed outline solutions for key technical and business barriers to the development of systems beyond 3G. In particular, MIND and BRAIN have designed an all-IP mobile access network, with QoS and mobility support, designed new middleware components and protocols to support seamless hand-over between heterogeneous access technologies and proposed QoS for wireless LANs. The key results of the BRAIN and MIND projects are presented in this paper.
