摘要

由于蜂窝移动通信网络的日益复杂,网络规划与优化在蜂窝移动通信中变得越来越重要。除了考虑诸如能源效率等新的关键性能指标外,各种无线电接入技术(例如3G及以上以及WiFi)和网络节点类型(例如微型和femto蜂窝)引起的增强的异质性导致规划过程的维度爆炸式增长。另一方面,自由度的增加也带来了新的优化技术。本文提出了一种优化蜂窝部署的新方法。该模型的基础是描述由封闭系统中多个粒子的物理特性驱动的力场(基站之间以及基站与环境之间)的相互关系。在此基础上,提出了一种在力作用下跟踪基站位置轨迹的算法,其重点是寻找具有最小净力的平衡状态。此外,还详细阐述了如何结合不同的力类型,以捕获网络的不同质量方面。

Base Station Placement Based on Force Fields
Network planning and optimization becomes more and more important in cellular mobile communications due to the growing complexity of the networks. Besides taking new key performance indicators into account such as energy efficiency, the augmented heterogeneity, caused by a variety of radio access technologies (e.g., 3G and beyond as well as WiFi) and network node types (e.g., micro and femto cells), leads to an exploding dimension of the planning process. On the other hand, the degrees of freedom increase as well, giving rise for new optimization techniques. In this paper a novel approach for optimizing cellular deployments is presented. The model is based on characterizing the interrelations (among base stations and between base stations and the environment) by force fields, motivated by the physics of multiple particles in a closed system. Further, an algorithm is proposed which tracks the trajectory of base station locations under the presence of forces, focusing on finding a balanced state with minimal net force. Also, it is elaborated on how to combine different force types in order to capture different quality aspects of a network.
