Abstract
A positioning method, a device, a system, a terminal, an LMF entity, and a medium, used to solve the problem of low positioning accuracy of UE-based OTDOA in the prior art. The method includes a terminal sending to a location management function (LMF) entity an auxiliary positioning data request message includes first identification information of a beam reference signal detected by the terminal itself, receiving from the LMF entity auxiliary positioning data of beam direction information of a beam reference signal including second identification information, and the second identification information is identification information of a beam reference signal sent by a neighboring base station and determined, according to the first identification information, by the LMF entity as being detectable by the terminal, and determining an RSTD of each beam reference signal having the first identification information or the second identification information, and determining position information of the terminal according to the determined RSTD and a beam direction of each beam reference signal.
