Abstract

Les modes de réalisation de la présente divulgation se rapportent à des procédés de communication, des appareils de communication, un terminal, un dispositif de réseau d'accès et un support de stockage. Un procédé de communication peut être appliqué à un terminal, le terminal prenant en charge une fonction de stockage et de transfert. Le procédé consiste à : lorsqu'une cellule de desserte a activé une fonction de stockage et de transfert, déterminer s'il faut mesurer une cellule voisine, sur la base de la qualité de signal de la cellule de desserte. Ainsi, dans les modes de réalisation de la présente divulgation, lorsque le terminal prend en charge la fonction de stockage et de transfert et que la cellule de desserte a activé la fonction de stockage et de transfert, il est déterminé s'il faut mesurer la cellule voisine sur la base de la qualité de signal de la cellule de desserte, de sorte que le terminal évite de réaliser une mesure inutile, ce qui permet de réduire la consommation d'énergie.
