Abstract

La présente invention concerne un procédé et un système de régulation de fréquence de localisation de terminal et un système et un procédé de régulation d'intervalle de localisation. Le procédé de régulation de fréquence de localisation de terminal comprend spécifiquement les étapes consistant à : effectuer une localisation selon une fréquence de localisation connue (S110) ; lire des données d'induction d'un capteur d'accélération (S120) ; lorsque les données d'induction satisfont une condition prédéfinie, régler de manière correspondante la fréquence de localisation en fonction de l'augmentation ou de la diminution, par rapport à une valeur de déplacement standard, d'une valeur de déplacement d'un terminal entre deux moments de localisation successifs, et augmenter ou diminuer la fréquence de localisation par rapport à la fréquence de localisation standard (S130). La localisation de terminal non seulement peut assurer la précision de localisation, mais peut également assurer une faible consommation d'énergie.
