“…Indeed, sharing of wireless access and infrastructure have become easier to achieve after the development of virtualization techniques. Regarding core network sharing, various sources [88,[145][146][147] propose techniques for virtualization of EPC in a mobile network, as well as corresponding SDN-based control architectures. Such control architectures are capable of dynamic reconfiguration of the transport network in order to reroute the traffic dynamically to the closest available virtualized EPC [88].…”

“…Their results show benefits and trade-offs of spectrum sharing between RAN tenants. Similarly, based on the 3GPP's DÉCOR technology, Kiess et al [147] investigate methods to upgrade existing heterogeneous networks with a slicing mechanism that requires minimal changes to select and configure the slices. In the scope of resource sharing, the SDN controller plays the role of either an orchestrator or a resource broker.…”

Regardless of the context to which it is applied, sharing resources is well-recognized for its considerable benefits. Since 5G networks will be service-oriented, on-demand, and highly heterogeneous, it is utmost important to approach the design and optimization of the network from an end-to-end perspective. In addition, in order to ensure end-to-end performance, this approach has to entail both wireless and optical domains, altogether with the IoT, edge, and cloud paradigms which are an indispensable part of the 5G network architecture. Shifting from the exclusive ownership of network resources toward sharing enables all participants to cope with stringent service requirements in 5G networks, gaining significant performance improvements and cost savings at the same time. The main objective of this paper is to survey the literature on resource sharing, providing an in-depth and comprehensive perspective of sharing by recognizing the main trends, the techniques which enable sharing, and the challenges that need to be addressed. By providing a taxonomy which brings the relevant features of a comprehensive sharing model into focus, we aim to enable the creation of sharing models for more efficient future communication networks. We also summarize and discuss the relevant issues arising from network sharing, that should be properly tackled in the future.

“…Option 2b takes 1.5 ms latency and mL = 2.5 length multiplier as parameters, resulting in a 60 km coverage radius. For comparison, cost calculations in [4] use a 72 km coverage radius.…”

“…In this paper, we examine how the costs of uRLL service deployments can be reduced. The paper is structured as follows: section 2 discusses how the latency requirements of uRLL services enforce the introduction of costly distributed deployment using coverage for Hungary as an example, and lists potential cost reduction options; section 3 deals with the possible unattended operation of datacenters hosting only low traffic volume of uRLL services [9]; section 4 presents the potential cost saving results compared to the costs of standard operation described in [4]; finally, section 5 concludes the paper.…”

“…U LTRA-reliable low latency (uRLL) communication introduces stringent requirements for 5G systems [1], [2], [3]. A recent cost study [4] shows that provisioning uRLL services can represent significant part of complete 5G deployments. This is triggered by the demanding service requirements: (i) for ultra-reliability the standard solution is to deploy Tier-4 attended datacenters [5], [6]; (ii) for low latency these datacenters must be placed either at the edge or close to the edge of the core network.…”

Ultra-reliable low latency (uRLL) communication in 5G dictates the deployment of distributed infrastructure with numerous datacenters for low latency, while hosting ultra-reliable services mandates attended datacenters. This would boost the operational costs of 5G network operators planning country-wide coverage for uRLL services. This paper examines how these operational expenses dominated by administrative costs can be reduced without impacting the quality of the provided uRLL service. Our results indicate that hosting uRLL services in unattended datacenters with increased hardware redundancy schemes can produce significant cost savings.
