To achieve the above objectives, a detailed study was conducted, and the outcome was no less relevant than the key objectives themselves. This includes:
The proposed solutions enable Assured QoS (AQoS) video delivery to the users by exploiting the synergies of next generation content generation and delivery protocols, CDNs, terrestrial and satellite networks. These synergies are exploited by proposing integrated satellite-terrestrial delivery scenarios. Such integrated scenarios also result in fostering business expansion of its key players: content providers, CDN and network operators, and the satellite industry.
Based on the business relevance in the deployment timespan and the services that most likely face growth issues in this deployment plan and where integration of terrestrial and satellite technologies would potentially alleviate bottlenecks, two main scenarios were identified and investigated in detail. These are:
S1: Satellite as hybrid backhaul of 5G ultra-dense networks
S4: Satellite as hybrid backhaul of home gateway.
The figure below depicts the simplified modular architecture of the combined scenarios.
The project was organized in 7 main work packages:
Future work recommendations, technology roadmap and standards evolution
The project has been concluded in May 2018. During the course of the project:
It was concluded that integration of satellite technologies as a backhaul to terrestrial technologies is a strong candidate to combat the problem of video delivery, especially live services.
