Abstract
The present application discloses a method for synchronizing encryption information between a SCell and UE, which includes that: the SCell transmits a COUNT value of RB established for the UE to a PCell; the PCell transmits the COUNT value received from the SCell to the UE; and the PCell receives a COUNT value of RB established on the SCell that is saved by the UE from the UE. Or, the SCell and the UE may directly exchange the COUNT value of RB. By the present application, the security and correctness of data can be ensured.
