Abstract

Dans les modes de réalisation de la présente invention, celle-ci concerne un procédé et un dispositif de commande associés au niveau de confiance de positionnement. Une alerte associée au niveau de confiance de positionnement est commandée et exécutée par un temporisateur et/ou un compteur, augmentant ainsi le niveau de confiance d'un système de positionnement, et augmentant la fiabilité de positionnement. Par exemple, le procédé de commande associé au niveau de confiance de positionnement consiste à : recevoir une première notification comprenant des informations associées au niveau de confiance de positionnement ; initier un premier compteur sur la base de la première notification, si la première notification est reçue une nouvelle fois ou de nombreuses fois après l'initiation du comptage par le premier compteur et pendant une durée prédéfinie d'un premier temporisateur, puis ajouter 1 au comptage du premier compteur et réinitier le premier temporisateur ; et, lorsque ou après que le comptage du premier compteur ait atteint une limite de comptage, exécuter une alerte associée au niveau de confiance de positionnement.
