receiving, by a base station, MDT configuration information sent by a core network or an operation, administration, and maintenance (OAM) network management system, wherein the MDT configuration information comprises first beam configuration information; and

sending, by the base station, an MDT measurement configuration message to user equipment (UE) based on the MDT configuration information, wherein the MDT measurement configuration message comprises second beam configuration information, and the second beam configuration information is the same as the first beam configuration information or the second beam configuration information is configuration information obtained after the first beam configuration information is processed,

wherein the method further comprises:

after sending the MDT measurement configuration message to the UE based on the MDT configuration information;

receiving, by the base station, an MDT measurement result sent by the UE, wherein the MDT measurement result is obtained after measurement is performed based on the second beam configuration information, and

sending, by the base station, the MDT measurement result to a trace collection entity (TCE).
