Abstract: Example methods for reporting user equipment location information and apparatus are described. In one example method, user equipment receives a first message, where the first message comprises a paging trigger indication, and the paging trigger indication is used to trigger the user equipment to report, when receiving a paging message, a measurement result of a positioning reference signal. The user equipment receives the paging message in an idle state or an inactive state. The measurement result of the positioning reference signal is reported by the user equipment based on the paging message.
