Method, apparatus, and system for controlling and measuring cell handover

A method for controlling a cell handover, comprising:

• acquiring terminal information;
• and
• sending a handover request including the terminal information to a target base station, to enable the target base station to perform, according to the terminal information, beamforming for a random access response of a terminal that hands over from a source cell covered by a source base station to a target cell covered by the target base station, wherein the handover request further includes information about a low power node that is located in the source cell and serves the terminal;
• wherein the terminal information comprises at least one of the following:
• (a) location information of the terminal and (b) precoding matrix indication information of the target cell measured by the terminal.

A base station, comprising:

• an acquirer, configured to acquire terminal information according to a received handover request that includes information about a low power node that is located in a source cell and serves a terminal;
• a processor, configured to:
• after a random access request sent by the terminal is received, perform, according to the terminal information acquired by the acquirer, beamforming for a random access response corresponding to the random access request;
• and
• a sender, configured to send the random access response for which the beamforming has been performed by the processor to the terminal, wherein the random access response comprises:
• configuration information of a resource required by the terminal during communication after the terminal hands over from the source cell covered by a source base station to a target cell covered by a target base station;
• wherein the terminal information comprises at least one of the following:
• (a) location information of the terminal and (b) precoding matrix indication information of the target cell measured by the terminal.
