Abstract

L'invention concerne un procédé de détection de service lorsqu'un système d'évolution à long terme (LTE) fonctionne sur une bande de fréquences non autorisée, un système de détection de service lorsqu'un système LTE fonctionne sur une bande de fréquences non autorisée, un terminal et une station de base. Le procédé de détection de service lorsqu'un système LTE fonctionne sur une bande de fréquences non autorisée consiste : à détecter si un signal de détection de cible existe ou non sur une sous-trame courante de la bande de fréquences non autorisée, de façon à confirmer si une station de base fournissant un service au terminal a ou non occupé un canal au repos ; lorsque le signal de détection de cible est détecté, à confirmer que la station de base a occupé le canal au repos, de telle sorte que la station de base exécute une planification de service sur la bande de fréquences non autorisée ; et lorsque le signal de détection de cible n'est pas détecté, à continuer pour détecter si le signal de détection de cible existe ou non sur des sous-trames suivant la sous-trame courante. Au moyen de la solution technique, la consommation d'énergie d'un terminal peut être efficacement réduite, et une position à laquelle une station de base occupe avec succès un canal peut être apprise avec précision tout en atténuant l'objectif d'économie d'énergie, de telle sorte que le cas dans lequel le terminal manque une chance de planification peut être évité de manière efficace.
