Abstract

La présente demande concerne un procédé de traitement d'exception de transfert intercellulaire, un dispositif et un support de stockage. Le procédé comprend : si un dispositif terminal n'a pas encore reçu une commande de transfert intercellulaire effectuée par une station de base source pour un premier rapport de mesure après l'envoi à la station de base source du premier rapport de mesure pour le (M-1)-ième temps, après le M-ième temps, à savoir la dernière opportunité d'envoi d'un rapport de mesure configurée dans une configuration de mesure émise par la station de base source, le démarrage d'une première temporisation ayant une première durée de synchronisation ; et, si le dispositif terminal n'a toujours pas reçu la commande de transfert intercellulaire émise par la station de base source à la fin de la première durée de synchronisation, de nouveau l'envoi une fois du premier rapport de mesure. De cette manière, même si le nombre d'envois de rapport de mesure configuré dans la configuration de mesure est atteint, le dispositif terminal peut toujours être déclenché pour envoyer à la station de base source le premier rapport de mesure jusqu'à ce que la commande de transfert intercellulaire effectuée par la station de base source pour le premier rapport de mesure soit reçue, ce qui assure au dispositif terminal de toujours recevoir la commande de transfert intercellulaire émise par la station de base source, et d'effectuer à temps un transfert vers un réseau disponible selon la commande de transfert intercellulaire, ce qui permet d'assurer la qualité de service.
