La présente invention concerne un procédé d'établissement de double connectivité et un appareil de communication. Un dispositif terminal arrête activement une mesure inter-fréquence ou inter-système sur la base d'un intervalle de mesure pendant l'établissement d'une double connectivité, ou lors de l'émission d'informations de configuration de double connectivité vers le dispositif terminal ou avant l'émission des informations de configuration de double connectivité, un dispositif de réseau ordonne au dispositif terminal d'arrêter la mesure inter-fréquence et/ou inter-système sur la base d'un intervalle de mesure, de telle sorte que pendant l'établissement d'une double connectivité, aucune augmentation de retard ne peut être provoquée par une mesure inter-fréquence et/ou inter-système.
