Abstract
AbstractSmall cells have emerged as a useful tool for supporting increased network capacity through network densification, but they can also be used to support edge cloud computing services. In this paper, we provide a preview of an innovative concept that tackles the consolidation of multi‐tenancy in such type communications infrastructures, as well as the placement of network intelligence and applications in the network edge. After surveing the challenges and the enabling technologies, we present the envisaged architecture to manage and control the Cloud‐Enabled Small Cell infrastructure. Also, at the operation level, we explain the potential advantages of adopting the proposed solutions on the long‐term evolution access networks. Copyright © 2016 John Wiley & Sons, Ltd.
Highlights
The fifth generation of mobile networks (5G) demands key features beyond what the current 4G can offer, such as significantly higher wireless capacity, reduced energy consumption per service and reliable connectivity with very low latency [1]
We review the implementation of CloudEnabled Small Cells (CESCs), able to support edge cloud computing in a multi-tenant, multi-service ecosystem
Network services (NSs) are supported by Virtualized Network Functions (VNFs) hosted in the light DC, leveraging on software defined networking (SDN) and network function virtualisation (NFV) functionalities that allow achieving an adequate level of flexibility and scalability at the cloud infrastructure edge
Summary
The fifth generation of mobile networks (5G) demands key features beyond what the current 4G can offer, such as significantly higher wireless capacity, reduced energy consumption per service and reliable connectivity with very low latency [1]. Thanks to the advent of cloud computing, software defined networking (SDN) and network function virtualisation (NFV), the idea of having general-purpose computing and storage assets at the edge of mobile networks has emerged It is a substantial change on the architecture of current mobile access nodes (cloudradio access network (C-RAN) approach), from being only a wireless head to cloud-enabled device equipped with, for example, novel processor architectures, graphics processing units, digital signal processors and/or fieldprogrammable gate arrays. In this line, new industry initiatives have already introduced the concept of mobile-edge computing [3] and the related key market drivers [4] implementations.
