Abstract

L'invention concerne un procédé et un dispositif de traitement de tâche de suivi de signalisation. Le procédé comprend les étapes suivantes : un système de suivi de signalisation acquiert une première signalisation générée lorsqu'une station de base suit un équipement utilisateur désigné, la première signalisation portant un identifiant de tâche correspondant à l'équipement utilisateur désigné envoyé par un réseau central à la station de base désignée après que l'équipement utilisateur accède à la station de base, et l'identifiant de tâche correspond à une tâche de suivi mise en mémoire cache par la station de base ; et, lorsqu'il est déterminé qu'il existe un identifiant d'équipement qui correspond à l'identifiant de tâche désignée correspondant à l'équipement utilisateur désigné conformément à une corrélation mémorisée, le système de suivi de signalisation ajoute l'identifiant d'équipement qui correspond à l'identifiant de tâche correspondant à l'équipement utilisateur désigné dans la première signalisation, et affiche du contenu de la première signalisation.<sb />
