Abstract-Fast growth of Internet content and availability of electronic devices such as smart phones and laptops has created an explosive content demand. As one of the 5G technology enablers, caching is a promising technique to off-load the network backhaul and reduce the content delivery delay. Satellite communications provides immense area coverage and high data rate, hence, it can be used for large-scale content placement in the caches. In this work, we propose using hybrid mono/multi-beam satellite-terrestrial backhaul network for off-line edge caching of cellular base stations in order to reduce the traffic of terrestrial network. The off-line caching approach is comprised of content placement and content delivery phases. The content placement phase is performed based on local and global content popularities assuming that the content popularity follows Zipf-like distribution. In addition, we propose an approach to generate local content popularities based on a reference Zipf-like distribution to keep the correlation of content popularity. Simulation results show that the hybrid satellite-terrestrial architecture considerably reduces the content placement time while sustaining the cache hit ratio quite close to the upper-bound compared to the satellite-only method.

“…The combination of satellite and terrestrial components to form a single/integrated telecom network has been regarded for long time as a promising approach to significantly improve the delivery of communications services [1] [2]. Despite the important and continued advances in satellite communications technologies, satellite communication offerings have not evolved at the same pace as terrestrial communications systems have done due to much lower economies of scale and inherent associated technological complexities [3].…”

“…The design of an efficient and flexible NAV/COM network among the FRs, the EVs and the ECC requires, in the longrange radio link, the system integration by space segments (satellite and HAPs) [12] [13]. This integration offers: the possibility of implementation of an emergency network, which can substitute the damaged one, a global coverage of the emergency area and a mean to connect the incident area with external areas [14].…”

Abstract-This paper describes the SALICE (Satellite-Assisted LocalIzation and Communication systems for Emergency services) project, an Italian National Research Project which has been recently funded by the Italian Ministry of Research; the SALICE project aims at identifying the solutions which can be adopted in an integrated reconfigurable NAV/COM device and studying its feasibility in realistic scenarios. The first goal of the SALICE project is the definition of the baseline scenarios and system architecture which will allow the design of new and effective solutions for what concerns integrated communications and localization techniques, Software Defined Radio (SDR) NAV/COM devices, satellite and HAPS integration in the rescue services, heterogeneous solutions in the area of intervention (IAN, Incident Area Network). Particular attention will be devoted to the optimization of the resources management strategies and to the cooperative localization of rescue entities (persons and means) that intervene in emergency situations.
