1. An electronic device comprising a circuit configured to:
serve a terminal device in a carrier aggregation manner through a plurality of cells;
receive from the terminal device measurement reports for a plurality of neighbor cells;
determine, based on the measurement reports, a destination base station to which the terminal device is to be handed over;
select one or more candidate cells to be accessed for the terminal device from all cells belonging to the destination base station in the plurality of neighbor cells; and
send to the terminal device, a radio resource control (RRC) connection reconfigure message carrying mobility control information which contains information of one or more cells of the cells belonging to the destination base station to be accessed, in order to hand over the terminal device to the destination base station,
wherein, the terminal device establishes an access to all cells, of the one or more cells of the cells belonging to the destination base station to be accessed, at a time after being handed over, and enters a carrier aggregation mode immediately upon establishing the access to the all cells, of the one or more cells of the cells belonging to the destination base station to be accessed.
