Until now, every evolution of communication standard was driven by the need for providing high-speed connectivity to the end-user. However, 5G marks a radical shift from this focus as 5G and beyond networks are being designed to be future-proof by catering to diverse requirements of several use cases. These requirements include Ultra-Reliable Low Latency Communications, Massive Machine-Type Communications and Enhanced Mobile Broadband. To realize such features in 5G and beyond, there is a need to rethink how current cellular networks are deployed because designing new radio access technologies and utilizing the new spectrum are not enough. Several technologies, such as software-defined networking, network function virtualization, machine learning and cloud computing, are being integrated into the 5G networks to fulfil the need for diverse requirements. These technologies, however, give rise to several challenges associated with decentralization, transparency, interoperability, privacy and security. To address these issues, Blockchain has emerged as a potential solution due to its capabilities such as transparency, data encryption, auditability, immutability and distributed architecture. In this paper, we review the state-of-art application of Blockchain in 5G network and explore how it can facilitate enabling technologies of 5G and beyond to enable various services at the front-haul, edge and the core. Based on the review, we present a taxonomy of Blockchain application in 5G networks and discuss several issues that can be solved using Blockchain integration. We then present various field-trials and Proof of concept that are using Blockchain to address the challenges faced in the current 5G deployment. Finally, we discuss various challenges that need to be addressed to realize the full potential of Blockchain in beyond 5G networks. The survey presents a broad range of ideas related to Blockchain integration in 5G and beyond networks that address issues such as interoperability, security, mobility, resource allocation, resource sharing and management, energy efficiency and other desirable features.

区块链在 5G 及以后网络中的应用回顾:分类、现场试验、挑战和机遇

迄今为止,通信标准的每一次演变都是由向最终用户提供高速连接的需求驱动的。然而,5G 标志着这一重点的根本转变,因为 5G 及更高版本的网络正在被设计为通过满足多个用例的不同要求来适应未来。这些要求包括超可靠低延迟通信、大规模机器类型通信和增强型移动宽带。为了在 5G 及以后实现这些功能,需要重新思考当前蜂窝网络的部署方式,因为设计新的无线电接入技术和利用新的频谱是不够的。软件定义网络、网络功能虚拟化、机器学习和云计算等多项技术,正在被集成到 5G 网络中以满足不同的需求。然而,这些技术带来了与去中心化、透明度、互操作性、隐私和安全相关的若干挑战。为了解决这些问题,区块链因其透明性、数据加密、可审计性、不变性和分布式架构等功能而成为一种潜在的解决方案。在本文中,我们回顾了区块链在 5G 网络中的最新应用,并探讨了它如何促进 5G 及以后的使能技术,以支持前传、边缘和核心的各种服务。基于审查,我们提出了 5G 网络中区块链应用的分类,并讨论了可以使用区块链集成解决的几个问题。然后,我们展示了使用区块链解决当前 5G 部署面临的挑战的各种现场试验和概念证明。最后,我们讨论了在 5G 网络之外实现区块链的全部潜力需要解决的各种挑战。该调查提出了与 5G 及以后网络中的区块链集成相关的广泛想法,这些想法解决了互操作性、安全性、移动性、资源分配、资源共享和管理、能源效率和其他理想功能等问题。
