This application relates to the field of wireless communications technologies, and provides a user equipment tracing method and a device, to implement joint trace for user equipment by two devices. The user equipment tracing method includes: receiving, by a master base station, a request message sent by a core network device, where the request message requests the master base station to initiate trace for user equipment UE; and sending, by the master base station, a first message to a secondary base station, where the first message carries first instruction information, and the first instruction information instructs the secondary base station to trace the UE.
