This application provide a MEC-based positioning method, a device, and a wireless communication system. The method includes: A first network element receives first positioning request information for requesting to position a terminal, and the first positioning request information carries identification information of the terminal. The first network element determines, based on the first positioning request information, a positioning functional entity for positioning the terminal, where the positioning functional entity is a positioning server. The first network element obtains second positioning request information based on the first positioning request information, and sends the second positioning request information to the positioning server. After receiving the second positioning request information, the positioning server sends measurement request information to the terminal via a user plane, to request the terminal to report measurement data. Then, the positioning server positions the terminal based on the measurement data reported by the terminal via the user plane.
