摘要: A method for positioning a terminal using signals received from a plurality of access points of at least one wireless telecommunications network is disclosed. According to some aspects, the terminal first retrieves identifiers of the access points from the received signals, then searches in a first database (BDP) for respective geographical position information for the access points. A first estimation of a position of the terminal or a positioning zone of the terminal is obtained from geographical position information of the access points, then topographical information corresponding to the first estimation of the position or the positioning zone is retrieved from a second database (SIG). A second estimation of the position of the terminal is performed using the topographical information thus obtained.
