Method for generating a track of movement states of a terminal device

Abstract

A method is provided for generating a track of movement states of a terminal device moving between a first time point T0 to a second time point T, wherein the movement state comprises a position of the terminal device. The method comprises that the server obtains positioning measurements at respective time points t(k) between T0 and T via the terminal device, wherein k is an integer and is an index of the time points, 0≤k≤N, N is an integer and N>0, t(0)=T0, and t(N)=T; the server determines for each time point t(k), the movement state of the terminal device at the time point t(k), wherein when 0≤k<N, the server determines the position of the terminal device at t(k) using the positioning measurements between a respective third time point t(k−a) and a respective fourth time point t(k+b), wherein a and b are integers, 0≤a≤k, and 0<b≤(N−k), when k=N, the server determines the position of the terminal device at t(k) using the positioning measurements between the third time point t(k−a) and t(k); and the server generates the track of the movement states of the terminal device by combining the determined positions.
