In some cases there may also be some uncertainty associated with the point. This uncertainty could arise from inaccuracies in data sets held by Geographic Information Systems, which mean that translations from civic addresses to physical coordinates are inaccurate. Such uncertainty is preferably represented as a 2X2 covariance matrix.

Abstract

L'invention concerne des systèmes et des procédés pour générer un profil représentatif d'une zone située autour d'un terminal radio mobile dans un réseau de communication, dans lesquels la localisation du terminal radio mobile comprend un certain degré d'incertitude. Ces systèmes et ces procédés sont caractérisés par les étapes consistant à: recevoir, au niveau d'un serveur, une demande d'enregistrement comprenant au moins une valeur sélectionnée parmi plusieurs paramètres de signal radio dans la zone située autour d'un terminal radio mobile; estimer la localisation du terminal radio mobile et une incertitude estimée associée à la localisation du terminale radio mobile en fonction d'au moins une valeur sélectionnée parmi lesdits paramètres de signal radio; effectuer une modélisation de propagation pour obtenir un ensemble de niveaux prédits de signal reçu associés aux cellules voisines au niveau de plusieurs points compris dans la zone située autour du terminal radio mobile, la répartition de ces points correspondant à l'incertitude associée à la localisation du terminal radio mobile; et traiter l'ensemble des niveaux prédits de signal reçu pour générer un profil représentatif de la zone située autour du terminal radio mobile.
