Abstract
A method is disclosed of estimating significant places visited by a mobile-terminal user for wireless communication via base stations. The method includes: collecting at least one communication log represented with consecutive communication events between the mobile terminal and connected one of the base stations in a coverage area of each mobile terminal, the base stations being identified by unique base-station identifiers (BS IDs), respectively, each communication event including date and time of communication and one of the BS IDs which is indicative of the connected base station; dividing each communication log into consecutive time-windowed segments, using a discrete time window moving in time; and, per each time-windowed segment, estimating at least one significant place visited by the user, based on a probability distribution with which the BS IDs appear in each time-windowed segment.
