Abstract: 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.

Abstract: A communication method is provided. A first network element receives an association identifier of a first application from a session management network element, where the association identifier is for associating different quality of service QoS flows of the first application. The first network element performs joint scheduling on the plurality of QoS flows of the first application that each carry the association identifier. Based on this solution, the first network element can identify, based on the association identifier, QoS flows belonging to a same application, and perform joint scheduling, and it is ensured that the QoS flows of the same application can arrive at a terminal device simultaneously or a time interval between arrivals at the terminal device is small, so that service experience of a user can be improved.
