Abstract

A locating method, user equipment, and a base station are provided. The locating method includes: receiving, by user equipment, a locating broadcast message sent by a base station, where the locating broadcast message carries a locating list, and the locating list includes an identifier of locatable user equipment. If the locating list does not include an identifier of the user equipment, the method includes ignoring a locating signal sent by the base station.
