Claim:
1. A method for selecting a target cell, comprising: receiving a handover request message transmitted by a source node; in response to the handover request message comprising an instruction to perform a detection, transmitting a dedicated detection message to each of a plurality of candidate cells, wherein the dedicated detection message carries a detection instruction, and wherein the detection instruction is used to instruct the plurality of candidate cells to detect uplink signal quality of a user equipment (UE), and wherein the plurality of candidate cells, upon receiving the detection instruction, each respectively detects the uplink signal quality of the UE, determines, according to a detection result, whether to transmit the detection result to a target node; and receiving a plurality of dedicated detection response messages, a dedicated detection response message of the plurality of dedicated detection response messages being transmitted by each of the plurality of candidate cells when the uplink signal quality of the UE is not lower than a specified threshold, wherein each of the plurality of dedicated detection response messages carries the detection result; and determining the target cell according to the detection results.
