The present invention discloses a method, a system and an apparatus for transmitting data in a CA manner. The method includes: creating, by a first base station currently serving a user equipment UE, EPS bearers under different component carriers CC Groups for the UE; setting, by the UE, different access stratum entities corresponding to the CC Groups to process data in the process of creating the EPS bearers; and determining, by the UE when transmitting or receiving data, a corresponding CC Group according to an EPS bearer that bears the data, and processing, by an access stratum entity corresponding to the CC Group, the data that needs to be transmitted or received, where a site is a first base station currently serving the UE, or a second base station currently serving the UE. The present invention ensures that the UE can receive the data that is transmitted over carriers aggregated from different bands of the first base station currently serving the UE and the second base station currently serving the UE, which improves data transmission throughput of the UE. |
