Abstract

Les modes de réalisation de la présente invention concernent un procédé de mesure, un appareil et un système. Dans ladite solution, un dispositif terminal détermine des premières informations de configuration ; et dans le cas où le dispositif terminal est dans un état de non-connexion au RRC, et qu'un résultat de mesure d'une cellule de desserte du dispositif terminal est inférieur ou égal à un premier seuil inclus dans les premières informations de configuration, le dispositif terminal mesure au moins un point de fréquence. Sur cette base, une mesure raisonnable peut être effectuée dans un état de non-connexion au RRC, de manière à faciliter la réalisation, par un dispositif de réseau, d'une détermination plus raisonnable et l'amélioration de la performance de capacité. Par exemple, lorsqu'on détecte qu'il existe une cellule voisine ayant une meilleure qualité, le dispositif terminal peut envoyer, lorsqu'il est dans un état de connexion au RRC, des informations de la cellule voisine au dispositif de réseau, de telle sorte que le dispositif de réseau effectue une optimisation de capacité d'une manière opportune en fonction des informations de la cellule voisine ; et lorsqu'aucune cellule voisine ayant une meilleure qualité n'est détectée, le dispositif terminal peut ou non envoyer au dispositif de réseau des informations d'indication indiquant qu'aucune cellule voisine ayant une meilleure qualité n'est détectée, de telle sorte que le dispositif de réseau effectue une optimisation de capacité de manière opportune.
