“…CellSlice [48] is another resource slicing proposal which does not need to modify the scheduling algorithms at the base stations but instead proposes a shaping mechanism at the gateway. The ideas are similar to other works, the network is divided into slices and each slice specifies a reservation of a fraction of the total resources.…”

Abstract-New architectural and design approaches for Radio Access Networks have appeared with the introduction of network virtualization in the wireless domain. One of these approaches splits the wireless network infrastructure into isolated virtual slices under their own management, requirements and characteristics. Despite the advances in wireless virtualization, there are still many open issues regarding the resource allocation and isolation of wireless slices. Because of the dynamics and shared nature of the wireless medium, guaranteeing that the traffic on one slice will not affect the traffic on the others has proven to be difficult. In this work, we focus on the detailed definition of the problem, discussing its challenges. We also provide a review of existing works that deal with the problem, analyzing how new trends such as SDN and NFV can assist in the slicing. We will finally describe some research challenges on this topic.

“…It is expected that the operators can save considerable amounts through RAN sharing over a 5-year period. It is also generally agreed that RAN sharing can lead to a faster roll-out of new technologies, e.g., LTE/LTE-A, whilst reducing costs, particularly for the green-field operators [106], [107].…”

The ongoing development of mobile communication networks to support a wide range of superfast broadband services has led to massive capacity demand. This problem is expected to be a significant concern during the deployment of the 5G wireless networks. The demand for additional spectrum to accommodate mobile services supporting higher data rates and having lower latency requirements, as well as the need to provide ubiquitous connectivity with the advent of the Internet of Things (IoT) sector, is likely to considerably exceed the supply, based on the current policy of exclusive spectrum allocation to mobile cellular systems. Hence, the imminent spectrum shortage has introduced a new impetus to identify practical solutions to make the most efficient use of the scarce licensed bands in a shared manner. Recently, the concept of dynamic spectrum sharing has received considerable attention from regulatory bodies and governments globally, as it could potentially open new opportunities for mobile operators to exploit spectrum bands whenever they are underutilised by their owners, subject to service level agreements. Although various sharing paradigms have been proposed and discussed, the impact and performance gains of different schemes can be scenario-specific and vary depending on the nature of the sharing parties, the level of sharing and spectrum access scheme. In this survey, we describe the main concepts of dynamic spectrum sharing, different sharing scenarios, as well as the major challenges associated with sharing licensed bands. Finally, we conclude this survey paper with open research challenges and suggest some future research directions

Abstract-There are several reports and white papers which attempt to precise 5G architectural requirements presenting them from different points of view, including techno-socio-economic impacts and technological constraints. Most of them deal with network slicing aspects as a central point, often strengthening slices with slice isolation. The goal of this paper is to present and examine the isolation capabilities and selected approaches for its realization in network slicing context. As the 5G architecture is still evolving, the specification of isolated slices operation and management brings new requirements that need to be addressed, especially in a context of End-to-End (E2E) security. Thus, an outline of recent trends in slice isolation and a set of challenges are proposed, which (if properly addressed) could be a step to E2E user's security based on slices isolation.
