Cell discovery method, device, and system

A cell discovery method, comprising:

• receiving, by a user equipment, first radio frequency information of a handover area, wherein the first radio frequency information is broadcast by a first base station;
• detecting, by the user equipment, whether the first radio frequency information of the handover area matches second radio frequency information acquired by the user equipment;
• and
• if the first radio frequency information of the handover area matches second radio frequency information acquired by the user equipment, measuring, by the user equipment, signal strength and/or signal quality of a cell at a frequency of a cell of a second base station or only of the cell of the second base station.

A first base station, comprising:

• a first information receiving unit, configured to receive first radio frequency information of a handover area;
• a second information receiving unit, configured to receive second radio frequency information that is reported by a user equipment served by a cell of the first base station;
• a detecting unit, configured to detect whether the second radio frequency information reported by the user equipment matches the first radio frequency information of the handover area;
• and
• a first information sending unit, configured to send, when the detecting unit detects that the second radio frequency information reported by the user equipment matches the first radio frequency information of the handover area, a measurement instruction message to the user equipment that reports the second radio frequency information for instructing the user equipment to measure signal strength and/or signal quality of a cell at a frequency of a cell of a second base station or only of the cell of the second base station.

A user equipment, comprising:

• a user receiving unit, configured to receive first radio frequency information of a handover area, wherein the first radio frequency information is broadcast by a first base station;
• a user detecting unit, configured to detect whether the first radio frequency information of the handover area matches second radio frequency information acquired by the user equipment;
• and
• a user measuring unit, configured to, when the user detecting unit detects that the first radio frequency information of the handover area matches second radio frequency information acquired by the user equipment, measure signal strength and/or signal quality of a cell at a frequency of a cell of a second base station or only of the cell of the second base station.
