Abstract

La présente invention se rapporte à un procédé et à un appareil permettant de sélectionner des porteuses qui contiennent des données de signalisation. Le procédé permettant de sélectionner les porteuses qui contiennent des données de signalisation, comprend les étapes suivantes : un ensemble de porteuses disponibles d'un terminal change (S502) ; un réseau d'accès acquiert le grade de chaque porteuse de l'ensemble de porteuses disponibles du terminal (S504) ; le réseau d'accès sélectionne la porteuse ayant le grade le plus élevé dans l'ensemble de porteuses disponibles comme étant la porteuse de support des données de signalisation pour le terminal (S506). Avec la présente invention, lorsque les porteuses disponibles pour le terminal sont accrues ou supprimées, la porteuse ayant le grade le plus élevé est sélectionnée de façon opportune dans l'ensemble de porteuses disponibles du terminal afin de remplacer la porteuse de support des actuelles données de signalisation, ce qui permet de garantir que les données de signalisation du réseau d'accès peuvent être transmises au terminal avec précision et de façon efficace.
