1. An electronic device, comprising:
circuitry configured to
communicate with a terminal device via at least one component carrier;
acquire a plurality of location points of the terminal device at different moments of time;
determine a speed and a moving direction of the terminal device based on the plurality of the location points and the different moments of time; and
in a case that the terminal device has left a service area;
determine a candidate component carrier, to serve the terminal device as a secondary component carrier together with the at least one component carrier in a carrier aggregation communication, based on the speed and the moving direction of the terminal device, wherein the candidate component carrier services another service area located in the moving direction of the terminal device; and
in a case that the terminal device accesses the candidate component carrier, deactivate the at least one component carrier or handover the at least one component carrier.
