Title
(EN) SCANNING FREQUENCY SELECTION FOR A WIRELESS DEVICE
(FR) BALAYAGE DE SÉLECTION DE FRÉQUENCE POUR DISPOSITIF SANS FIL
Abstract
(EN)
Methods, systems, and devices for wirelessly scanning frequency bands based on device location and/or mobility are presented. The method can include (i) scanning, by a mobile device and according to a first wireless scanning protocol, frequencies within first frequency bands that correspond to a first geographic region and second frequency bands that correspond to a second geographic region; (ii) determining at least one of an estimated location or an estimated mobility characteristic of the mobile device; (iii) determining, based on at least one of the estimated location or the estimated mobility characteristic, to adjust a scheduled time for the mobile device to initiate scanning according to a second wireless scanning protocol; (iv) and initiating at the scheduled time, scanning according to the second wireless scanning protocol.

La présente invention concerne des procédés, des systèmes et des dispositifs pour balayer sans fil des bandes de fréquence sur la base de la localisation et/ou de la mobilité d'un dispositif. Le procédé peut comprendre (i) le balayage, par un dispositif mobile et selon un premier protocole de balayage sans fil, de fréquences dans des premières bandes de fréquences qui correspondent à une première région géographique et des secondes bandes de fréquences qui correspondent à une seconde région géographique; (ii) la détermination d'au moins une d'une localisation estimée ou d'une caractéristique de mobilité estimée du dispositif mobile; (iii) la détermination, sur la base d'au moins l'une de la localisation estimée ou de la caractéristique de mobilité estimée, d'ajuster un temps ordonnancé pour que le dispositif mobile initie un balayage selon un second protocole de balayage sans fil; (iv) et l'initiation au moment ordonnancé, du balayage selon le second protocole de balayage sans fil.
