Abstract
La présente invention, qui se rapporte au domaine des communications sans fil, concerne un procédé et un dispositif de rapport de mesure et de jugement de séparation de support ou de commutateur afin de résoudre le problème sur la manière selon laquelle une station de base source juge correctement de déclencher ou non un processus de commutation ou un processus de séparation de support pour une station de base cible dans un scénario de déploiement d'un réseau hétérogène. Dans cette application, après une réception d'un événement de mesure relatif à une commutation et signalé par un terminal, une station de base source détermine une cellule cible selon l'événement de mesure; détermine la cellule cible ou un type de station de base cible dont fait partie la cellule cible, juge selon le type de déclencher ou non un processus de commutation ou un processus de séparation de support pour la station de base cible, et déclenche le processus de commutation ou le processus de séparation de support pour la station de base cible selon un résultat du jugement, résolvant de cette façon le problème sur la manière selon laquelle une station de base source juge correctement de déclencher ou non un processus de commutation ou un processus de séparation de support pour une station de base cible dans un scénario de déploiement d'un réseau hétérogène.
