Abstract

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.

Dependent claims

A method for updating a database of a geolocation server using a wireless communication system, said database including a table storing identifiers of transmitting devices, each transmitting device identifier being associated in the table with at least one piece of position information representative of the geographical position of the transmitting device, said wireless communication system including an access network and at least one terminal adapted to exchange messages with the access network according to a first wireless communication protocol and to receive messages emitted by the transmitting devices according to a second wireless communication protocol, said method including:

detecting, by the terminal, for at least one transmitting device, an identifier of said transmitting device from a message emitted by said transmitting device according to the second wireless communication protocol,
emitting, by the terminal, to the access network and according to the first wireless communication protocol, a message including the identifier of the transmitting device,
determining, by the access network, without using the geolocation server, a piece of position information representative of the geographical position of the terminal,
said method implementing either one or both of the following two possibilities:
when the identifier of the transmitting device is present in the table:
performing a consistency check between the piece of position information of the terminal determined by the access network and at least one piece of position information associated with the identifier of the transmitting device in the table,
updating the table according to the result of the consistency check,
when the identifier of the transmitting device is not present in the table, updating the table by adding the identifier of the transmitting device associated with a piece of position information determined according to the piece of position information of the terminal determined by the access network.

A server of an access network of a wireless communication system used to update a database of a geolocation server, said database including a table storing identifiers of transmitting devices, each transmitting device identifier being associated in the table with at least one piece of position information representative of the geographical position of the transmitting device, said wireless communication system also including at least one terminal adapted to exchange messages with the access network according to a first wireless communication protocol and for receiving messages transmitted by the transmitting devices according to a second protocol wireless communication, said server being configured to:

receive a message emitted by the terminal according to the first wireless communication protocol, said message including at least one identifier of a transmitting device detected by the terminal,
determine, without using the geolocation server, a piece of position information representative of the geographical position of the terminal,
emit to the geolocation server a query message including the identifier of the transmitting device,
said server being further configured to implement either one or both of following possibilities:
when the identifier of the transmitting device is present in the table:
receive from the geolocation server a reply message including at least one piece of position information associated with the identifier of the transmitting device in the table,
perform a consistency check between the piece of position information of the terminal determined by the access network and said at least one piece of position information associated with the identifier of the transmitting device in the table,
emit a message intended to update the table according to the result of the consistency check
when the identifier of the transmitting device is not present in the table, emit a message intended to add into the table the identifier of the transmitting device associated with a piece of position information determined according to the piece of position information of the terminal determined by the access network.
