Claim Text:
1. A method for locating a short message SMS coming from a mobile user equipment in a telecommunication network comprising: a mobile network of a mobile network operator (MNO) comprising: a fixed network of an Internet service provider (ISP), comprising a fixed core network and a plurality of individual boxes forming termination equipment of the fixed network, the boxes having respective unique box identification data, some of the boxes being provided with a short-range cellular emitter/receiver module of the femtocell type allowing a temporary wireless coupling with a nearby mobile user equipment, the mobile network being organized into a plurality of location areas (LA) each identified by a location area code (LAC); each location area gathers a set of service areas (SA) each identified by a service area code (SAC), each service area gathering a geographically homogeneous set of cells of the mobile network; the femtocells operate in open mode, each femtocell of the mobile network being able to be coupled to any user equipment (MS) registered with the mobile network operator (MNO) and being nearby the femtocell, without this user equipment having been previously registered in the individual box; wherein upon emission of an SMS from a user equipment (MS) coupled to a femtocell (FT), the method comprises: a) sending by the SMS storage centre (SMSC) to the location platform (GMLC) platform of a user equipment location request; b) sending by the location platform (GMLC) to the commutation centre (VMSC) of a rough location request; and c) sending by the commutation centre (VMSC) to the location platform (GMLC) of a rough location comprising the service area code (SAC) and location area code (LAC) corresponding to the femtocell; d) determining by the location platform (GMLC) whether the location area (LA) includes a specific additional service area SA in which are gathered femtocell identifiers; e) in the affirmative, sending by the location platform (GMLC) to the femtocell, via the commutation centre (VMSC), of a fine location request message; f) obtaining by the commutation centre (VMSC) from the femtocell of a fine location comprising unique data of identification of the box associated with the femtocell; and g) transmitting of the fine location (VMSC) by the commutation centre to the SMS storage centre (SMSC).
