Abstract
Matrices of movement in a geographic area are computed. The method subdivides the geographic area into geographic zones. Each entry of a matrix includes an indication of movements from one geographic zone to another in the respective time slot. The geographic area of interest is subdivided into geographic area portions, and mobile communication terminals in the geographic area calculate and provide respective geographic position estimates to a data processing system. An overall number of geographic position estimates are distributed by assigning to each geographic area portion a respective number of geographic position estimates. Covered geographic portions are determined among said plurality of geographic area portions, and each one of the determined covered geographic area portions is assigned a respective weight. A correspondence map establishing a correspondence between the network cells and the geographic zones is generated, and the weights are used in computing the matrices.
