“…In [4], the authors discuss the value of edge caching for content distribution in 5G-backhauled satellite and present the architecture also adopted by the present paper; yet, the implementation is restricted to WiFi access after the satellite segment (i.e., not 5G RAN). [5] presents over-the-air tests of a backhauled cellular network with distributed core functions, yet the implementation is based for 4G, not 5G. [6] presents an over-the-air demo of satellite integration with 5G core network, however the RAN part is implemented with a 4G eNB and local EPC component.…”

The use of satellite as backhaul in 5G networks is currently the most mature approach for satellite/5G integration, extending the coverage of 5G to underserved areas, beyond the reach of terrestrial backhaul infrastructures. This paper presents an actual implementation and over-the-air tests of a 5G Stand-Alone network, where a satellite link is used to interconnect the 5G Core with the RAN. Furthermore, local breakout is adopted to enable edge computing at the satellite edge; this is achieved by virtualizing and off-loading the 5GC User Plane Function to the edge. The performance of each configuration is evaluated with generic traffic, using the Open5GENESIS experiment automation suite, as well as in the context of an actual use case (5G smart agriculture).

“…In addition, we implemented cross‐network quality‐of‐service (QoS) functionalities for a better spectrum management and usage of the satellite capacity. Based on the first results presented in Völk et al, 11 we refined the CES concept for various architectures of mobile PPDR networks that rely on a bandwidth limited satellite backhaul. In this paper, we evaluate these architectures complemented by measurements taken from true field trials, in which the mobile cell has been realized by a van with a SATCOM‐on‐the‐Move (SOTM) antenna.…”

Summary A secure and flexible communication infrastructure for the use of broadband and IP‐based services is becoming more and more important in the context of Public Protection and Disaster Relief (PPDR). Government agencies and emergency responders need to be able to react quickly to emergencies across the globe. In particular, satellite‐based 5G mobile networks can support government agencies during their critical tasks. To support the standardization committees and the industry, it is required to evaluate new architectures for such networks by utilizing testbeds and field trials. In this article, we propose and investigate architectures for mobile PPDR networks with satellite backhaul to ensure Communication on‐the‐Move. The flexibility within the architectures comes with the distribution of the core network nodes at the edge of the network applying the Core‐Edge Split concept. The presented results show that already existing interfaces of the Evolved Packet Core 3GPP standard allow satellite‐based 5G networks tailored to the needs of government authorities.

“…To evaluate 5G technologies over a convergent satellite-terrestrial architecture and to support the 3GPP and the European standardization efforts, practical demonstrations by means of testbeds, as shown in [17,18] are required. They are pioneering for this kind of architecture and provide a platform to demonstrate the 5G satellite use cases.…”

The 5G vision embraces a broad range of applications including the connectivity in underserved and remote areas. In particular, for these applications, satellites are going to play a role in future 5G networks to provide capacity on trains, vessels, aircraft, and for base stations around the globe. In this paper, a 5G edge node concept, developed and evaluated with over-the-air tests using satellites in the geostationary orbit, is presented. The article covers a testbed demonstration study in Europe with a large-scale testbed including satellites and the latest standardization for the network architecture. The main goal of this testbed is to evaluate how satellite networks can be best integrated within the convergent 5G environment. The over-the-air tests for 5G satellite integration in this article are based on a 3GPP Release 15 core network architecture.
