SDN/NFV-enabled satellite communications networks: opportunities, scenarios and challenges

In the context of next generation 5G networks, the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and more flexible integration of satellite and terrestrial segments, providing satellite network further service innovation and business agility by advanced network resources management techniques. Through the analysis of scenarios and use cases, this paper provides a description of the benefits that SDN/NFV technologies can bring into satellite communications towards 5G. Three scenarios are presented and analysed to delineate different potential improvement areas pursued through the introduction of SDN/NFV technologies in the satellite ground segment domain. Within each scenario, a number of use cases are developed to gain further insight into specific capabilities and to identify the technical challenges stemming from them.Peer ReviewedPostprint (author's final draft

5g and Iot digital era: the transformation of mobile network operators into end-to-end solution providers

The forthcoming 5G and IoT large-scale implementation reveals new business opportunities in completely new sectors that mobile network operators should seize. This survey paper wants to identify the necessary transformations such operators must undergo to build a sustainable competitive advantage in the future industry. A qualitative research composed of semi-structured interviews incumbents’stronger intent of diversification and creates the base for strategic recommendations.A sample of recent actions carried out by mobile network operators to improve their position in the 5G and IoT environments is shown at the end of the work
