摘要: 面向海量小蜂窝部署环境,在异构蜂窝网络跟踪区域(TA)规划过程中会出现位置更新信令不均匀和乒乓效应等现象。针对该问题,提出一种基于Newman快速社区检测算法的TA规划方案。将TA规划建模为复杂网络中的社区检测问题,并应用社区检测中的Newman算法得到网络中的社区划分结构。通过引入社区划分的模块度概念衡量方案性能,实验结果表明,与基于博弈的TA规划方案相比,该方案在小蜂窝数量和小蜂窝泊松分布期望值较高的情况下模块度平均提高0.107,规划性能较优。

Abstract: For the large-scale deployment environment of Small Cellular(SC),the existing planning processes of the Tracking Area(TA) in Heterogeneous Cellular Network(HCN) have such phenomena as uneven signaling of position update and ping-pong effect.Aiming at this problem,this paper proposes a TA planning scheme based on Newman rapid community detection algorithm.TA planning is modeled as the community detection problem in the complex network,and the Newman algorithm in the community detection is used to get the community partition structure in the network.The concept of modularity of community detection is introduced to measure the performance of the proposed scheme.Experimental results show that,in the case of large number of SC and high Poisson distribution expectation of SC,compared with the TA planning scheme based on game,the modularity of the proposed scheme is increased by 0.107 on average,which shows a better planning performance.

Key words: Heterogeneous Cellular Network(HCN), Tracking Area(TA) planning, modularity, community detection, Poisson distribution expectation
