It has been shown in [31] that multicast subgrouping overcomes the weakness of the conventional techniques and allows for the efficient delivery of multimedia content over the emerging satellite systems.…”

The next generation of mobile radio communication systems-so-called 5G-will provide some major changes to those generations to date. The ability to cope with huge increases in data traffic at reduced latencies and improved quality of user experience together with a major reduction in energy usage are big challenges. In addition, future systems will need to embody connections to billions of objects-the so-called Internet of Things (IoT) which raise new challenges. Visions of 5G are now available from regions across the world and research is ongoing towards new standards. The consensus is a flatter architecture that adds a dense network of small cells operating in the millimetre wave bands and which are adaptable and software controlled. But what is the place for satellites in such a vision? The chapter examines several potential roles for satellites in 5G including coverage extension, IoT, providing resilience, content caching and multicast, and the integrated architecture. Furthermore, the recent advances in satellite communications together with the challenges associated with the use of satellite in the integrated satellite-terrestrial architecture are also discussed.

“…That is, a user in a remote area expects the same high quality service as a user living in an urban region. Instead, satellite networks need to be integrated as a native component into existing terrestrial infrastructures as already acknowledged previously [13]- [15]. Thereby, a converged satellite and terrestrial network is formed, so that traffic can be offloaded dynamically to the satellite connection, whenever it makes sense.…”

Whilst broadband Internet connectivity has become highly important, providing broadband connectivity nonetheless remains a considerable challenge, particularly in rural and remote regions where the deployment of optical fibers faces economical obstacles. A promising option to address this issue is that of the most recent satellite systems, capable of providing high capacities virtually everywhere. However, compared to most terrestrial systems, satellite networks have very different link and, more importantly, latency characteristics, which often render them only barely usable for delay intolerant traffic. Thus, convergence of terrestrial and satellite networks is required, so that only certain traffic flows can be offloaded onto a supplemental satellite connection. In this work, we propose a network architecture relying on modern Software Defined Network (SDN) concepts, which enable dynamic traffic offloading in a converged satellite and terrestrial network, in order to relieve the load in a narrowband terrestrial network. We show that with limited overhead, a traffic can be offloaded, leading to an increase in the user's Quality-of-Experience (QoE).

“…Multimedia service delivery is one of the fastest growing and most demanding services over satellite networks . The multimedia services are ultimately enjoyed by end users, and almost 90% of users simply change the provider instead of continuing to accept a service with lower quality; thus, providing users with high QoE is necessary to network service providers.…”

Summary Satellite networks are promising alternatives to deal with the increasing traffic volume and provide universal access for end users. Quality of experience (QoE) as an aggregate of user perception and network quality will be a critical success factor for multimedia service delivery over satellite networks. Quality of experience prediction based on quality of service (QoS) has received much attention recently, but it has been little investigated in satellite networks. In this paper, on the basis of the modular neural network and deep belief networks (DBNs), we design a QoE/QoS mapping method for multimedia services over satellite networks to translate QoS parameters into user QoE. The task of QoE/QoS mapping for multimedia services is decomposed into several different subtasks by using traffic classification. Heterogeneous DBNs are used to learn the mapping relationships between QoE and QoS for different types of services (ie, subtask) simultaneously. An integrative approach based on relative distance is exploited to select subneural network(s) to predict resulting QoE collaboratively. To determine the weight parameters of the QoE/QoS correlation model, the dataset composed of QoS parameters and subjective opinion scores is built on the basis of satellite network simulator and subjective test. Finally, the effectiveness of our QoE/QoS mapping method is validated, and the relationship between adoption rating and opinion scores is analyzed.
