Abstract

Un procédé, un appareil, et un système de communication sans fil sont divulgués par la présente demande. Le procédé de communication sans fil comprend : un terminal est configuré avec un groupe de cellules primaires et un groupe de cellules secondaires. Lorsqu'il est déterminé que le terminal surchauffe, un message d'informations de défaillance du groupe de cellules secondaires est envoyé à un dispositif de réseau ; un premier message de reconfiguration de commande de ressources radio (RRC) est reçu en provenance du dispositif de réseau, le premier message de reconfiguration RRC étant utilisé pour ordonner de libérer des cellules secondaires du terminal ; et selon le premier message de reconfiguration RRC, les cellules secondaires du terminal sont libérées. Étant donné qu'au moins une cellule secondaire dans le groupe de cellules secondaires est libérée, le volume de service du terminal peut être réduit ; puis la consommation d'énergie du terminal peut être réduite, la température du terminal peut être abaissée, et le terminal évite ainsi d'être dans un état de surchauffe pendant une longue période de temps. Au cours du procédé précité, lors de l'interaction entre le terminal et le dispositif de réseau, le terminal peut achever la libération des cellules secondaires sans arrêt et mise sous tension, garantissant ainsi que le terminal peut toujours communiquer sans interrompre le service du terminal.
