Disclosed is a method for updating a database of a geolocation server using a wireless communication system. The database includes a table associating an identifier of a transmitting device with at least one piece of information on its geographical position. The communication system includes an access network and a terminal communicating with the access network and with the transmitting devices according to two distinct protocols. The terminal receives a message emitted by a transmitting device and including an identifier of the transmitting device. The terminal emits a message with this identifier to the access network. The access network determines a piece of information on the geographical position of the terminal. A consistency check is performed between the piece of position information of the terminal determined by the access network and the piece of position information present in the table. The table is updated based on the consistency check.

Method for updating a database of a geolocation server

A method for geolocating a terminal of a wireless communication system. The terminal receiving a message transmitted by a transmitting device of interest. An ambiguous item of identification information is obtained from the transmitting device of interest. The terminal transmitting to the access network a message including the ambiguous item of identification information from the transmitting device of interest. The access network estimating an approximate geographical position of the terminal. The transmitting device of interest is identified in a table storing a list of transmitting device identifiers and the respective geographical positions of the transmitting devices. The precise geographical position of the terminal is estimated according to the geographical position of said transmitting device of interest.
