CONCEPT AND EVALUATION OF MOBILE CELL CONNECTIVITY OVER A SATELLITE BACKHAUL FOR FUTURE 5G NETWORKS

摘要

A terrestrial network deployment with mobile cell connectivity using a bandwidth limited satellite backhaul is being investigated in terms of the integration of state-of-the-art 4G commercial off-the-shelf network components. A testbed is analyzed for providing end-to-end quality of service and flexible resource allocation on the satellite link using a novel multi-carrier modem technology with dynamic bandwidth allocation. To minimize network traffic delay and enable backhaul independent internal cell communication, virtual nodes are exploited to distribute core network components to the edge of the cell co-located with the radio base stations.
