INDOOR LOCATING MOBILE TERMINALS IN A MOBILE CELLULAR TELECOMMUNICATION NETWORK

摘要

A process for indoor location of a mobile cellular terminal (3) equipped with a transceiver apparatus capable of communicating with a mobile cellular telecommunication network (2), through a system including at least one transmitter apparatus (5a-5g), present inside an indoor environment (6;A-G), and at least one of the mobile terminals (3) equipped with at least one receiver apparatus (4), capable of receiving data transmitted by at least one of the transmitter apparatuses (5a-5g) present inside the indoor environment (6;A-G) and of relaying them to a locating station (7) through the transceiver apparatus over the mobile cellular telecommunication network (2), including the following steps, wherein: at least one of the transmitter apparatuses (5a-5g) present in the indoor environment (6;A-G) transmits at least one identifier (ID;A-G) of the indoor environment (6;A-G) where the transmitter apparatus (5a-5g) is situated; the receiver apparatus (4) of the mobile terminal (3) receives the identifier (ID;A-G) transmitted by at least one of the transmitter apparatuses (5a-5g); the transceiver apparatus of the mobile terminal (3) relays the identifier (ID;A-G) or data associated therewith to the locating station (7) through the mobile cellular telecommunication network (2); and the locating station (7) locates the mobile terminal (3) depending on the identifier (ID;A-G) or the data associated therewith received from the mobile terminal (3) through the mobile cellular telecommunication network (2), by associating the identifier (ID;A-G) with the position of the indoor environment (6;A-G) after consulting an existing database (9) accessible to the locating station (7), the database (9) including information associating the identifier (ID; A-G) with data relating to the position of the indoor environment (6;A-G) where the transmitter (5a-5g) that transmitted it is situated, and wherein the identifier (ID) is associated with at least one fixed communication terminal (8) present inside the indoor environment (6), and wherein the data relating to the position of the indoor environment includes a geographic address (LOCATION) of the fixed communication terminal (8).
