Network Slicing Optimization for Integrated 5G-Satellite Networks

The growth of Internet traffic especially with respect to mobile broadband services is one of the main motivations towards the integration of satellite and 5G networks. A key building block for the overall network orchestration will be the efficient definition and management of network slices, which eventually translates into efficient allocation of physical and computing resources. This paper explores the resource allocation problem in the case of railway communications building on satellite and 5G connectivity. Some exemplary candidates solutions have been elaborated, whose validation through simulation campaigns has shed some lights about the main factors impacting on the overall system performance and the most effective resource allocation solutions.
