5G Satellite Integration
Date: Monday July 9
Time: 11:00 – 4:00
A growing demand for a tremendous increase in the mobile data traffic with two-thirds of it being the video, with virtually zero latency gigabit experience networks and the emergence of IoT and its expected billions of devices connected to the Internet, dictates the need for new system architectures and standards. The vision of 5G in delivering the advanced services such as virtualization, enabler of smart cities, smart environments, and M2M has recently attracted enormous attention by industry, academia, and standard organizations. Satellite communications play a significant role as a complementary solution to terrestrial networks due to its characteristics of ubiquitous coverage, broadcast, multicast, and emergency/disaster recovery. These invited sessions will be an occasion for major researchers and stakeholders in 5G satellite to present their standpoints and enhance understanding of the promising (but yet challenging) paradigm and deployment practices of 5G Satellite.

Softwarised satellite ground segment networks for improved terrestrial-satellite integration: 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 does not only allows for satellite communications services to be delivered in a more flexible, agile and cost-effective manner than done today but greatly facilitates the seamless integration and operation of combined satellite and terrestrial networks. This presentation will discuss the applicability of NFV and SDN technologies in the satellite ground segment, focusing on two use cases analised in the context of the H2020 VITAL project: the NFV applicability in satellite gateway implementation and the SDN aplicability for traffic engineering in a satellite-terrestrial mobile backhauling network.
European H2020 Sat5G Approach to Integration of 5G and Satellite Communications: The introduction and global roll out of enhanced Mobile Broadband (eMBB) services within 5G raises coverage and network dimensioning issues across underserved and unserved areas, especially in low ARPU regions of emerging markets, and on mobile platforms (e.g. vessels and aircraft). Satcom systems are the only economic solution to address these scenarios provided that they are seamlessly integrated into the future 5G architecture and optimum efficiency is achieved via technological collaborations between 5G mobile and satcom systems.
SaT5G will bring satcom into 5G by defining optimal satellite-based backhaul and traffic offloading solutions. It will research, develop and validate key 5G technologies in order to take the best value of satcom capabilities (e.g. multicast for content and Virtualised Network Function (VNF) delivery) and mitigate its inherent constraints (e.g. latency). It will identify novel business models and economically viable operational collaborations that integrate the satellite and terrestrial stakeholders in a win-win situation. SaT5G will validate, through specific research pillars, the required technology bricks that will enable the targeted markets to be addressed.
The project gathers key stakeholders from the global satcom industry, partnering with Mobile Network Operators (MNOs), SMEs and research centres with the expertise from cellular network operation, architecture design, transmission, virtualisation, network management, business modelling, security, content multicast and caching. The SaT5G External Advisory Board involves MNOs, satellite and vertical stakeholders.
SaT5G will capitalise on and drive the standardisation effort initiated in 3rd Generation Partnership Project (3GPP) and the European Telecommunications Standards Institute (ETSI) by several consortium partners and Advisory Board members. A key feature of SaT5G is demonstrations of satellite integration in 5G network testbeds to validate the technology developed and scenarios.
5G and satellite network security integration open issues and solutions: 5G phase 1 specifications were completed, and the world is preparing for the arrival of 5G networks. A major design goal of 5G is a high degree of flexibility to better cater for specific needs of actors from outside the telecom sector (e.g. automotive industry, mission-critical organisations). Satellites systems and networks are also developing fast. The integration of 5G and satellite network is not clear yet in particular in relation to network and security performances. The talk will address end-to-end QoS provisioning open issues for such integrated system. Also the talk will address security and privacy open issues such the use of various trust models, policies and authentication schemes. The talk then will examine a specific and a very promising application area called Intelligent Transport Systems (ITS) and how 5G and satellite network integration will enable large scale deployment of ITS, maximizing network performance and providing security and privacy to users despite the large amount of personal data sharing in this system.

3GPP Standardization Efforts to Integrate Satellite and Non-Terrestrial Networks in 5G New Radio: The roles and advantages of satellites in 5G have been studied in 3GPP. It is recognized that, as part of the mix of access technologies for 5G, satellite coverage brings the added value especially for mission critical and industrial applications where ubiquitous coverage and availability is crucial.
The standards group is now standardizing use of non-terrestrial networks (NTN), i.e. satellite and others, including unmanned aerial vehicles, such that multiple access networks can be used to support 5G networks. The first NTN study item started in February 2018 and successfully ended in May 2018. The focus of the study item was primarily on channel modeling for NTN. Channel modeling is now officially completed and the result is captured in TR 38.811. Besides channel modeling, discussions over 5G New Radio (NR) impact of NTN are held for a variety of topics such as: Random Access Channel (RACH), Hybrid-ARQ (HARQ), Phase Tracking Reference Signal (PTRS), Demodulation Reference Signal (DMRS), Initial Access, and Timing Advance. The next phase of the NTN study item is expected to be approved in the upcoming 3GPP RAN Plenary meeting in June. The focus of the upcoming study item will be on the solutions for NR to support NTN.
This presentation will provide a detailed review for the ongoing activities and efforts for NTN standardization in 3GPP. The presentation covers the channel models proposed for NTN. It also provides a comprehensive list of hurdles, challenges, and impacts of integration of satellite and NTN in the existing 5G NR land-based radio systems.
