Generation of Realistic Railway Based Mobility Scenarios

Planning and operating cellular networks for railway coverage is a challenging task due to the trains high speeds, the number of users traveling and the surroundings. Simulations of the radio environment are a crucial part of the radio network planning process as they allow to test different network layouts and configurations. Accurate simulations however require appropriate input data. In this paper, we present a process for the generation of realistic railway based mobility scenarios from public domain environmental data. From clutter, building and height data, the train routes, the positions of base stations and their antennas as well as the user movement will be derived. Using these realistic scenarios will allow for detailed system-level simulations for specific locations and their characteristics.
