Abstract

La présente divulgation relève du domaine technique des communications et concerne en particulier un procédé de résélection de cellule d'interférence, un terminal, un dispositif réseau, un dispositif de communication et un support de stockage. Le procédé de resélection de cellule consiste à : d'après les informations de resélection de cellule associées à un service de multidiffusion, effectuer une resélection de cellule, les informations de resélection de cellule associées au service de multidiffusion étant envoyées à un terminal par un dispositif réseau. Selon la présente divulgation, un dispositif réseau peut envoyer des informations de resélection de cellule associées à un service de multidiffusion à un terminal, et le terminal peut effectuer une resélection de cellule d'après les informations de resélection de cellule associées au service de multidiffusion. Comme les informations de resélection de cellule sont associées à un service de multidiffusion, le terminal effectue une resélection de cellule d'après les informations de resélection de cellule associées au service de multidiffusion, de sorte que la resélection d'une cellule prenant en charge le service de multidiffusion est facilitée, ce qui permet au service de multidiffusion d'être exécuté de manière continue dans la cellule resélectionnée.
