Softwarisation of the ground segment system for combined terrestrial-satellite communications

Satellite networks are expected to become an integral part of upcoming 5G systems. In this regard, the adoption of 5G mainstream softwarisation technologies such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) arises as a necessary step in the evolution of satellite ground segment systems (e.g. satellite gateways and terminals). This softwarisation would allow satellite communications services to be delivered in a more flexible, agile and cost-effective manner than done today. The applicability of NFV and SDN technologies in the satellite ground segment has been researched by H2020 VITAL project in the context of combined terrestrial-satellite networks. This extended abstract outlines the scope of two case studies from VITAL project outcomes that will be presented at WWRF39.Peer Reviewe
