Considering both the temporal information and the spatial information, we construct a data-voice coupled bipartite network. The edge weight distribution of the temporal network is lognormal. The maximal connected subgraph of the spatial network is denoted as S-network and it is a small world network. The edge weight of the S-network obeys power-law distribution. The frequency of coupling events in core is higher than that in periphery. The core-periphery model can effectively identifies spatio-temporal areas where data-voice coupling events occur intensively.
