通过部署更多的接入点来提高频谱的空间重用性历来是提高蜂窝通信网络容量的最有效手段。今天的移动网络面临着数据服务的激增和对数据流量的总体需求，这些需求在过去几年里一直在强劲增长。因此，通过部署较小的低功率节点来增加网络容量对移动网络运营商来说至关重要。虽然这种小型接入点在许多方面在概念上等同于传统的蜂窝基站，但预期的大量小型小区及其更加动态的计划外部署在网络管理领域提出了各种挑战。本文讨论了这些挑战，并回顾了最新的建模技术以及选定的网络管理技术。
Increasing the spatial reuse of frequency spectrum by deploying more access points has historically been the most effective means to improve the capacity of any cellular communication network. Today's mobile networks face a proliferation of data services and overall demand for data traffic that has been strongly increasing over several years. As a result, increasing network capacity through the deployment of small lower power nodes is of key importance for mobile network operators. Although such small access points are conceptually equivalent to conventional cellular base stations in many ways, the expected large number of small cells as well as their much more dynamic unplanned deployment raise a variety of challenges in the area of network management. This paper discusses such challenges and reviews state-of-the-art modeling as well as selected network management techniques.
