A method for localizing a mobile terminal (13) in an area under radio coverage of a cellular communication network (12) and of a localization point (11). The method includes the steps of: transferring to the mobile terminal (13) a localization point identifier (LP-ID) of the localization point (111, . . . , 113), the mobile terminal (13) being under radio coverage of the localization point (111, . . . , 113); and transferring the localization point identifier (LP-IDs) via the cellular communication network (12) from the mobile terminal (13) to a server (123) connected to the cellular communication network (12).
