INDOOR LOCATING MOBILE TERMINALS IN A MOBILE CELLULAR TELECOMMUNICATION NETWORK

摘要

A mobile cellular terminal (3) equipped with a transceiver device capable of communicating with a mobile cellular telecommunication network (2) via a system comprising at least one transmitter device (5a-5g) At least one of the mobile terminals 3 is connected to at least one of the transmitter devices 5a-5g which is located inside the indoor environment 6 At least one receiver device capable of receiving data transmitted by the mobile cellular telecommunication network (2) and relaying the data to a locating station (7) via the transceiver device Wherein at least one of the transmitter devices (5a-5g) present in the indoor environment (6; AG) is installed in the indoor environment (6 ; A- G) of at least one identifier (ID; A - G); The receiver device (4) of the mobile terminal (3) receiving the identifier (ID; A - G) transmitted by at least one of the transmitter devices (5a-5g); Characterized in that the transceiver device of the mobile terminal (3) relays the identifier (ID; A - G) or its associated data to the positioning station (7) via the mobile cellular telecommunication network step; And associating the identifier (ID; A - G) with the location of the indoor environment (6; AG) after consulting an existing database (9) accessible to the positioning station (7) (7), depending on the identifier (ID; A - G) or the associated data received from the mobile terminal (3) via the mobile cellular telecommunication network (2) And positioning the mobile terminal (3). The database 9 stores the information associating the identifier (ID; A - G) with the data related to the location of the indoor environment 6 (AG) where the transmitter 5a-5g that transmitted it is located Wherein said identifier (ID) is associated with at least one fixed communication terminal (8) residing within said indoor environment (6), said data relating to the location of said indoor environment being associated with said fixed communication terminal (LOCATION).
