A method and device for cell switching are disclosed. The method includes: according to the indication of a cell switching command sent by an access network equipment, a user equipment determines the subframe for uplink transmission in the cell switching process, herein the transmission direction of the subframe for uplink transmission in the cell switching process does not change in the cell switching process; in the process of switching to a target cell, the user equipment sends a message, which is used for switching to the target cell, to the access network equipment by using the determined subframe. In the embodiment of the invention, in the process of a UE handing over to a target cell, because the transmission direction of the subframe for uplink transmission does not change, the message, which is used for switching to the target cell and sent by the UE with the subframe for uplink transmission, can be correctly received by the access network equipment, thereby the success ratio of a UE handing over to a target cell is improved.
