Abstract

La présente invention concerne un procédé et un appareil pour déterminer le moment de prise d'effet d'une configuration dans un scénario de connexion multiple, ainsi qu'un système de communication. L'appareil est disposé sur au moins l'un des dispositifs de réseau participant à une connexion multiple, et comprend : une première unité de transmission qui transmet le temps de prise d'effet d'une configuration du dispositif de réseau à un équipement terminal ; et une première unité d'application qui permet au dispositif de réseau d'appliquer la configuration au moment de prise d'effet. Selon la présente invention, au moins un des dispositifs de réseau participant à la connexion multiple transmet le moment de prise d'effet d'une configuration à un équipement terminal, ce qui permet de faciliter la coïncidence des moments pour appliquer la configuration entre l'équipement terminal et le dispositif de réseau dans la connexion multiple.
