Abstract: In the next few years, mobile networks will undergo significant evolutions in order to accommodate the ever-growing load induced by increasingly pervasive smartphones and connected objects. Apart from innovations in radio technologies, future-generation cellular systems will be designed for flexibility and reconfigurability. New architectural paradigms, such as cloud radio access and software-defined networking, will support a dynamic management of network resources that adapts to the spatiotemporal fluctuations of the mobile demand. This vision roots in the capability of mining large-scale traffic data collected in the network, so as to understand how resources should be established, relocated or released in an automated manner. In this talk, I will address a fundamental problem in knowledge discovery from mobile traffic data, i.e., classification. I will present hierarchical classifiers that allow extracting typical profiles of the mobile network demand, in time and space. Then, I will show how exploratory factor analysis can be used for a joint spatial and temporal classification of the mobile network demand, with advantages in terms of richess and interpretation of profiles. Evaluations with extensive real-world data bring out a limited number of time periods that show a similar stable spatial distribution of the mobile demand, and highlight categories of urban areas characterized by analogous demand evolution over time. Interestingly, the latter results have applications beyond networking and in geoinformatics, as an effective way to automatically detect land uses.
