摘要：High speed train (HST) passengers demand uninterrupted multimedia services throughout the journey. Rapidly fading radio channels, Doppler frequency shift and fast handover problem are a few challenges which the existing mobile communication systems encounter, while supporting the mobile user in high speed trains (around 350 km/h). In this article we briefly overview the solutions proposed for provisioning high quality internet broadband servicesto the travelers. These solutions are based on the available access network technologies. We have also discussed the drawbacks and technical difficulties involved for implementing the respective solutions. Lastly, we have briefed about the newly proposed C-HSTC architecture and the RADIATE architecture derived from the existing solutions, aimed to provide a cost-effective andhigh-quality communications solution for provisioning broadband Internet services in HSTs
