Abstract

La présente demande se rapporte au domaine technique des communications, et divulgue un procédé et un appareil de rapport d'informations de mesure, un procédé et un appareil de réception d'informations de mesure, un dispositif, et un support de stockage. Le procédé de rapport d'informations de mesure comprend l'étape suivante : un dispositif terminal rapporte un résultat de mesure d'une première cellule. Selon le procédé de rapport d'informations de mesure fourni par la présente demande, un dispositif de réseau peut apprendre, dans le temps, le résultat de mesure de la première cellule associée à une configuration de transfert intercellulaire conditionnel, ce qui permet d'aider le dispositif de réseau à modifier, mettre à jour ou supprimer, dans le temps pour un terminal, des informations de configuration associées au transfert intercellulaire conditionnel, réduire la réservation de ressources invalides du dispositif de réseau, faciliter la libération, dans le temps, de ressources réservées utilisées par le terminal pour une faible probabilité, et améliorer l'utilisation de ressources d'un système de communication en arrière-plan de transfert intercellulaire conditionnel.
