Homophily In The Diffusion Of The 4G Users In Communication Network

With the development of the telecommunication market, everyone has almost a mobile phone, the number of telecommunication users tends to saturation, so using the existed users to create higher value has become the focus of operators. After 4G license issued, how to quickly guide 3G users migrate to 4G, to improve the penetration of 4G users, that is rather essential. From homophily of the social network studying the spread of 4G users, and grasping the user’s psychological process to adopt 4Q for enterprise to develop accurate marketing strategy is of great significance.This thesis was based on large amounts of customer data of The China Unicom, and studied the diffusion of 4G users. The main works of this thesis are as follows:1. The research results at home and abroad were studied from the aspects of the diffusion of innovations and the homophily of social networks, their research methods and techniques were analyzed, the shortcomings of the research on the diffusion of innovations and the merits of this research content were discussed.2. By the analysis of real data, we established the data fields needed, and the communication network was constructed according to the calling data. Compared the advantages and disadvantages of the existed community mining algorithms, and combined with the real data of this subject, and CNM algorithm was used to mine the communities of communication network. Because this study is a dynamic process, it is necessary to set up observation points. According to our actual situation, it established observation points, and analyzed their feasibility, and finally analyzed the distribution of the communities.3. Based on the statistical hypothesis test theory, the statistical software R was used to model using the stochastic actor based models. The random effect model of the meta-analysis was used to evaluate the model, and the association heterogeneity of the model was tested to analyze whether the degree of variation between the different effect values was caused by the stochastic cause.The results indicate that the propensity of a user to adopt 4G is affected by friends who have already adopted, increases with the number of friends that have already adopted.However there is not enough evidence for users will be friends because they adopted the 4G.According to the conclusions, so operators in the 4G promotion should pay more attention to mining the users with higher influence, and focusing on guiding them adopt 4G. In addition,paying attention to the use of word of mouth for accurate marketing may increase the business rapidly.
