Improving media streaming services for train passengers with 5G

This is the authors' abstract. We don't add key points for this paper.

In the research project 5G-VICTORI we are looking into how fifth generation mobile network technology (5G) can help improve video streaming services for train passengers. We use the principle of a local 5G-based data link between trains and 5G base stations in railway stations to load media assets to a caching server in the train, from which passengers can stream media via the regular apps of video-on-demand (VoD) service operators. The paper gives an outlook on the challenges in delivering VoD services to trains via this type of cloud-edge platform. These include determination of relevant content for upload to the cache, enable good quality-of experience (QoE) live streaming and WiFi traffic shaping for fair allocation of network bandwidth to streaming clients.
