Abstract

La présente invention concerne un procédé et un appareil d'analyse de données, ainsi qu'un équipement utilisateur. Dans le procédé, si des informations de commande SC-MCCH obtenues à partir d'une période de répétition cible d'une période de modification courante ne sont pas analysées avec succès, à ce moment, les informations de commande SC-MCCH peuvent également être acquises respectivement à partir de périodes de répétition ultérieures à la période de répétition cible, et celles-ci sont analysées jusqu'à ce que l'analyse réussisse ; et si celles-ci ne sont pas analysées avec succès dans une sous-trame correspondant à une période de répétition d'une période de modification, les informations de commande SC-MCCH peuvent également être successivement et respectivement obtenues à partir de diverses périodes de répétition d'une période de modification suivante, jusqu'à ce que les informations de commande SC-MCCH soient analysées avec succès. La fréquence d'acquisition et d'analyse d'informations de commande SC-MCCH est améliorée, et le taux de réussite d'analyse des informations de commande SC-MCCH est augmenté, ce qui permet d'obtenir rapidement et avec succès les informations de commande SC-MCCH.
