Abstract

La présente invention concerne un procédé, un appareil et un système de communication de cellule. La présente invention se rapporte au domaine de la communication et est utilisée pour résoudre le problème technique associé à la faible disponibilité d'une ressource d'interface hertzienne utilisée par une macrostation de base. Selon l'invention, le procédé fait appel : à l'établissement d'une connexion de commande de ressources radio (RRC) avec un équipement d'utilisateur (UE) et au transfert d'une signalisation de RRC audit UE par le biais de ladite connexion RRC; à l'envoi, respectivement, d'une signalisation d'indication d'établissement d'un support radio de signalisation secondaire (SBR) audit UE et à ladite station de base de petite cellule dans le but d'indiquer le fait que ledit UE et ladite station de base de petite cellule établissent ledit SRB secondaire qui est utilisé pour transférer la signalisation RRC entre ledit UE et la station de base de petite cellule. L'invention est utilisée pour assurer la communication de cellule dans le domaine de la communication.
