电信社群网络用户行为特征及演化分析

通过某地移动客户的通话数据构建电信社群网络,并对其网络结构进行分析,发现电信社群网络并不满足小世界特征,而且该网络的演化是以边生长为主导。基于该结构特征,构建电信社群网的演化模型,发现网络非均匀性与节点的朋友圈数目、连接概率和新增节点边数有关。其研究结论对新运营商通过营销策略的制定,推动电信社群网络快速向小世界网络演化具有积极的现实意义。

Analysis of User Behaviors and Evolution in Telecom Social Network

The restructuring of China’s telecommunication industry has intensified the competition among telecommunication enterprises.To gain competitive edge,telecommunication enterprises need to adopt new technology to recruit potential users and maintain good customer relationships.The current literature on customer behaviors in the telecommunication industry mainly rely on the cluster analysis of basic properties of user data,without taking into account the interaction between users and network characteristics.Based on the complex network theory,this paper regards telephone number as the nodes and regards contact numbers as the interactive edge to build a telecommunication social network. We apply the research method in the existing literature to test the overall characteristics of this telecommunication social network.Based on the network characteristics,we propose an evolving model and derive major influential factors for a telecommunication social network.In addition,we investigate the trend of change of the telecommunication social network under different influencing factors.Our results can provide theoretical support for establishing fast and stable telecommunication social networks for mobile phone operators. We explore the evolving mechanism of this particular social network,and provide the following findings:(1) We collect and analyze four-month user communication data in the area.We use software to construct a telecommunication social network.We analyze the structure and overall characteristics of this network.The results show that the telecommunication social network does not have the characteristics the so-called small-world networks.The connectivity is rather poor and the telecommunication social network grows according to the edges and local preferential attachment.(2) Based on network characteristics of the telecommunication network,we propose a telecommunication network evolution model.A simulation test shows that the model can reproduce some structure properties of the telecommunication social network.In addition,the number of nodes and the number of new nodes edges affect network heterogeneity.(3) After analyzing factors that affect evolutionary characteristics of the telecommunication network,we propose relative achievements and marketing strategies to improve our telecommunication social network and facilitate the transformation of telecommunication network into a small-world network.In addition,we provide theoretical bases for telecommunication enterprises to reorganize their strategies.
