论文摘要
中性宿主小细胞提供商（SCP）代表了超密集移动网络5G视觉的关键要素。但是，当前的商业模式主要集中在大型场所（例如体育场和酒店连锁店）的多年协议上。这些业务协议是通过约束服务水平协议（SLA）来监管的，对于较小的SCP而言，这些协议往往过于麻烦且昂贵。结果，中立的主机模型无法扩展到其全部潜力。在本文中，我们提出了一个框架，以使中小型参与者参与蜂窝市场，作为向移动网络运营商（MNOS）提供网络资源的提供商。为此，我们回顾了SCP可以用于中性宿主部署的当前和新兴频谱和技术机会。我们还建议将支持区块链的智能合约用作用于小型SCP的传统SLA的简单且具有成本效益的替代品。为了证明这一点，我们描述了基于以太坊的智能合约平台的概念证明，用于SCP和MNO之间的最佳及时服务。我们对都柏林市中心潜在基于智能合同的部署的模拟表明，在考虑区域中收到的信号强度平均增加了10美元。
Neutral Host Small Cell Providers (SCP) represent a key element of the 5G vision of ultra-dense mobile networks. However, current business models mostly focus on multi-year agreements for large venues, such as stadiums and hotel chains. These business agreements are regulated through binding Service Level Agreements (SLAs), which tend to be too cumbersome and costly for smaller scale SCPs. As a result, the neutral host model does not scale up to its full potential. In this paper, we propose a framework to enable the participation of small- to medium-sized players in the cellular market as providers offering network resources to Mobile Network Operators (MNOs). To this purpose, we review the current and emerging spectrum and technology opportunities that SCPs can use for neutral host deployments. We also propose the use of blockchain-enabled smart contracts as a simple and cost-efficient alternative to traditional SLAs for small-scale SCPs. To demonstrate this, we describe a proof of concept implementation of an Ethereum-based smart contract platform for best-effort service between an SCP and an MNO. Our simulations on potential smart contract-based deployments in city centre Dublin show that the received signal strength in the considered area will increase by an average of $10$ percent.
