The invention discloses a terminal identification method and device; wherein the method comprises following steps of obtaining transmission signaling sent by each network element in an LTE (Long Term Evolution) system, wherein identity information of each terminal identified by each network element side is carried in the transmission signaling; obtaining target identity information for identifying same user equipment from the obtained identity information; and identifying the user equipment according to the target identity information. According to the method and the device provided by the invention, the technical problem in the prior art that the user equipment cannot be identified accurately because the terminal identifiers on different network elements are inconsistent is solved.
