Abstract
(EN)
A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.
(FR)
Selon la présente invention, un signal de référence transmis périodiquement par une station de base dans un réseau sans fil peut présenter certaines propriétés exclusives pour aider à empêcher la détection et l'utilisation du signal pour un positionnement non autorisé de dispositifs mobiles. De façon plus précise, un nœud de réseau peut obscurcir et introduire une variation temporelle dans le mappage entre des signaux de positionnement et des stations de base physiques correspondantes. Le nœud de réseau peut également introduire des variations temporelles dans les champs d'un almanach de station de base (BSA pour Base Station Almanac) fourni à des équipements utilisateurs (UE pour User Equipment) abonnés. Les informations transmises aux équipements utilisateurs abonnés peuvent être cryptées.
