Figure 4. Spatial distribution of mobile base stations and an illustration of phone call
interactions among cells.
In this work, on one hand, for individual spatio-temporal mobility pattern
analysis, the corresponding approximate movement trajectories of each mobile
subscriber were created by connecting his/her a series of geo-referenced call
records in space and time.
