Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de traitement de communications. Le procédé consiste à : déterminer si un terminal respecte une condition de déclenchement prédéfinie ; si le terminal respecte la condition de déclenchement prédéfinie, lancer une mise à jour de zone de suivi (TAU) après que le terminal déconnecté a été reconnecté et avant que la prochaine TAU périodique soit lancée ; le terminal déconnecté étant reconnecté effectuant au moins une ou plusieurs des opérations suivantes : réacquérir, par le terminal, après que les ressources de fréquence radio de celui-ci ont été préemptées, les ressources de fréquence radio, et réacquérir, par le terminal, après la perte du signal de réseau, le signal de réseau. Par conséquent, lorsque le terminal déconnecté a été reconnecté, une TAU peut être lancée après que le terminal déconnecté a été reconnecté et avant que la prochaine TAU périodique ne soit lancée, ce qui élimine la nécessité d'attendre jusqu'à la prochaine TAU périodique, de manière à réduire le problème selon lequel le terminal, lorsqu'il est appelé, pourrait subir une déconnexion en cas de détachement implicite, ce qui améliore la qualité de communication.
