Abstract
A method and an apparatus of establishing dual-connectivity to transmit data are disclosed. A PCell of the UE carries out a mapping function and realizes a PDCP layer, a RLC layer, a MAC layer and a physical layer, and a SCell of the UE carries out quality packet data to data radio bearer mapping and realizes a PDCP layer, a MAC layer and a physical layer, in which a core network transmits data of the UE to the PCell, the PCell maps a QoS Flow of the data of the UE which is quality packet data to a data radio bearer on a mapping layer, performs path split, transmits data of respective paths to the UE through the PCell and SCell of the UE, and the UE regroups the data of the respective paths on the PDCP layer, and transmits the regrouped data to an application layer.
