Revealing Service Visit Characteristics in Mobile Internet

Abstract

With the rapid development of mobile networks and popularization of smart phones,the scale of mobile Internet users is explosively growing,and various kinds of services have emerged.To investigate the characteristics of user access of different kinds of services,we set up a weighted user-service bipartite network model.Before using our model to analyze the user access characteristics,we categorize the main services in mobile Internet into twelve types.Then,based on the real data sets respectively collected in 2010and 2011from a WAP gateway of one main Mobile Telecom Carrier in Chongqing province,we target to expose the characteristics of service visit styles from four aspects:access interest,clicks,traffic features,and access relevance.We have several interesting findings:(a)the top four service categories being visited are the portal,search,online social networks and e-book;(b)the number of service categories that user visited well fits exponential distribution,while the user visiting intensity fits power law;and(c)the volume of traffics on websites whose clicks are high would show strong self-similarity,but those having low clicks would not.However,when the volume of clicks on a website reaches a certain high level,it would show the self-similarity.Moreover,(d)with respect to access relevance,which means the users'access transfers among different service categories,we find that the portal and search are the top two kinds of services which tightly correlated with other service categories,followed by the e-mail and online social networks.
