An increase of data traffic is required for a higher reliability of the communication system with a safety of passengers and trains. Global system for mobile communication-railway (GSM-R) network has been considerd as the most widely used commercial wireless network in the world. In case of the Korean railway wireless network, there is a critical problems in the simutaneous use of various wireless network systems, such as very high frequency (VHF), trunked radio system-ASTRO (TRS-ASTRO), terrestrial trunked radio (TRS-TETRA). A long term evoloution-railway (LTE-R) wireless communication based systems was recently introduced to overcome the limitations and problems of the conventional railway communication system in the operation and the maintenance.
This investigation reviewed some problems of domestic railway wireless network and latest technologies. This thesis also suggested several efficient gradual establishment methods of railway wireless convergence network based on LTE-R network for interworking with the conventional GSM-R network. The proposed suggestions in this thesis would realize the optimum construction of the next-generation railway wireless convergence network based on LTE-R network.
