Abstract: A detection apparatus may include: An emitting component (301) emits a first beam. A light splitting component (3021) changes an optical path of a return optical signal from a detection region to obtain a first return optical signal and a second return optical signal, propagates the first return optical signal to a first detection component (3022), and propagates the second return optical signal to a second detection component (3023). The first detection component (3022) detects the first return optical signal to obtain a first electrical signal. The second detection component (3023) detects the second return optical signal to obtain a second electrical signal. The first electrical signal and the second electrical signal are for determining distance information of a target.

Abstract: A method includes: obtaining, by a first network element, first information that carries location information of a first terminal device, determining an identifier set based on the first information, where the identifier set includes an identifier of the first terminal device, communication information of the first terminal device can be obtained based on the identifier of the first terminal device; sending, by the first network element, a request to a second network element based on each identifier in the identifier set, to determine location information of a terminal device corresponding to the identifier, so that the first network element can obtain location information of the terminal device corresponding to each identifier in the identifier set; and comparing the location information of the first terminal device with the location information of the terminal device corresponding to each identifier in the identifier set to obtain the identifier of the first terminal device.
