Summary:A method for processing assistance data associated with positioning of a mobile device as described herein includes estimating an initial location of the mobile device within an area; designating the initial location of the mobile device as a focal point; retrieving a subset of hierarchical assistance data as a function of the focal point; and generating a multi-level assistance data structure for the area centered at the focal point. Un procédé de traitement de données d'assistance associées au positionnement d'un dispositif mobile tel que décrit dans l'invention comprend l'estimation d'un emplacement initial du dispositif mobile dans une zone ; la désignation de l'emplacement initial du dispositif mobile en tant que foyer ; la récupération d'un sous-ensemble de données d'assistance hiérarchique en fonction du foyer ; et la génération d'une structure de données d'assistance multi-niveau pour la zone centrée sur le foyer.
