A method for implementing soft handover based on a carrier aggregation technology, a base station, and a terminal. The method is applied in a scenario of complementary carrier coverage, and comprises: a terminal and a base station receiving and transmitting data simultaneously through multiple cells corresponding to multiple component carriers in a carrier aggregation manner, wherein one cell is a primary cell and the rest cells are secondary cells; the base station determining, according to a measurement result of the terminal, to hand over the primary cell of the terminal to one of the secondary cells, and marking the secondary cell as a target secondary cell; and the base station maintaining a service connection between the terminal and the target secondary cell, and notifying the terminal of handing over a control signaling connection to the target secondary cell. |
