Title
(EN) MEASUREMENTS FOR INDOOR NAVIGATION
(FR) MESURES POUR NAVIGATION INTÉRIEURE
Abstract
(EN) A method of obtaining and using access point signal information includes: receiving signals at a mobile device from a first set of access points during a passive measurement; and performing a first active measurement at the mobile device for the first set of the access points, including: sending at least one first communication each sent toward a respective one of the access points of the first set; and receiving at least one second communication each corresponding to, and responsive to, one of the at least one first communication and received from a corresponding one of the access points of the first set; where the passive measurement and the first active measurement is each performed repeatedly with the first set of the access points being reestablished at each repeat performance of the passive measurement, and with the passive measurement being performed less often than the first active measurement.
(FR) L'invention concerne un procédé permettant d'obtenir et d'utiliser des informations de signaux de points d'accès comprenant : l'étape consistant à recevoir des signaux au niveau d'un dispositif mobile en provenance d'un premier ensemble de points d'accès au cours d'une mesure passive; et l'étape consistant à effectuer une première mesure active au niveau du dispositif mobile pour le premier ensemble de points d'accès, comprenant : l'étape consistant à envoyer une ou plusieurs premières communications envoyées chacune vers un point d'accès respectif des points d'accès du premier ensemble; et l'étape consistant à recevoir une ou plusieurs deuxièmes communications correspondant chacune à, et réagissant à, l'une de ladite au moins une première communication et reçue en provenance d'un point d'accès correspondant des points d'accès du premier ensemble; la mesure passive et la première mesure active étant chacune effectuées de manière répétée avec le premier ensemble de points d'accès rétablis à chaque exécution répétée de la mesure passive, et la mesure passive étant effectuée moins souvent que la première mesure active.
