网络共享通常被誉为解决蜂窝网络不断增加的负载的一种有前景且经济高效的方法。然而，其实际有效性在很大程度上取决于所加入的网络之间的相关性——直观地讲，加入具有完全相同的负载和完全相同的部署的两个网络没有任何好处。在本文中，我们分析了两家爱尔兰运营商的部署和流量轨迹，以（i）研究它们在空间和时间上的相关性，以及（ii）评估网络共享带来的潜在收益。通过我们的分析，我们能够证明网络共享在使空间上的负载更加规律、改善蜂窝网络的操作和性能方面非常有效。
Network sharing is often hailed as a promising and cost-effective way to tackle the ever-increasing load of cellular networks. However, its actual effectiveness strongly depends on the correlation between the networks being joined -- intuitively, there is no benefit in joining two networks with exactly the same load and exactly the same deployment. In this paper, we analyse the deployment and traffic traces of two Irish operators to (i) study their correlation in space and time, and (ii) assess the potential benefit brought by network sharing. Through our analysis, we are able to show that network sharing is remarkably effective in making the load more regular over space, improving the operations and performance of cellular networks.
