摘　　要：为深入理解移动通话网络的行为模式,文中对45天内超过280万手机用户的通话记录进行分析,研究加权有向的移动通话网络拓扑结构特性。为探讨移动通话网络的行为模式,文中重点研究了特征关系动力学:节点入度和出度、度与强度的关系都呈现出此长彼长的关系,用户通话时长和通话频率之间主要呈现非线性关系,网络中节点的度越大,平均聚类系数就越小。得出结论:移动通话网络是一个典型的社会网络,但也有着独特的拓扑特征及其关系动力学,并存在一些不稳定性。To deeply understand the behavior mode of the mobile phone network,present an analysis of the mobile call records from over 2. 8 million individuals over 45 days,and give some perspective about its topological structure characteristics of weighted and directed mobile call network. To discuss the behavior mode of the mobile call network,focus on the dynamical properties of the characteristics＆#39;correlation. A significant positive correlation between the in-degree and the out-degree of single nodes is found,so is that between the degree and strength;the correlation between call duration and call frequency mostly appears to be non-linear. The average clustering coef-ficient diminishes with the increase of nodes degree. Finally,it is concluded that mobile call network is a typical social network,although with unique topological structure characteristics and the dynamical properties of those characteristics＆#39; correlation,and instability in certain aspects.
