Abstract

L'invention concerne un procédé de commutation d'antennes, un appareil et un terminal. Lorsqu'il est déterminé qu'un terminal exécute une mesure interfréquence ou intersystème, et qu'une première antenne actuellement adoptée n'est pas l'antenne optimale, une antenne active du terminal est commutée sur l'antenne optimale, et l'antenne optimale correspond à une bande de fréquence adoptée pour une mesure interfréquence ou intersystème, de sorte qu'il soit garanti que lorsqu'un terminal ayant au moins deux antennes exécute une mesure interfréquence ou intersystème, un rapport de mesure peut refléter les situations réelles de manière relativement précise de façon à améliorer l'efficacité de communication.
