Problems solved by technology

If the radius of an ordinary land cell is 1km, the number of cell reselections for the UE is about 6 times. According to the existing MSE scheme, the MSE of the UE is estimated to be in the High-mobility state; while the cell radius in the NTN GEO scenario is 100km, and the UE moves 6.67km within 240s, so the number of cell reselections for the UE is 1. According to the existing MSE scheme, the MSE of the UE is estimated to be in the Normal-mobility (low-speed movement) state, while for For a moving speed of 100km / h, the Normal-mobility status is obviously inaccurate
[0004] Therefore, in the NTN GEO scenario, the existing MSE scheme cannot estimate the correct UE state

Embodiment Construction

[0063] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0064] figure 1 It shows a schematic flowchart of a method for estimating a mobile state of a terminal provided in this embodiment, including:

[0065] S101. In an NTN GEO scenario, acquire the residence time of the terminal in each NTN GEO cell.

[0066] Wherein, the dwell time is the dwell time of the terminal once in the current NTN GEO cell; the dwell time is the period from when the terminal enters the current NTN GEO cell to when the terminal leaves the current NTN GEO cell.

[0067] For example, the terminal at t 1 Switch from cell A to cell B at time, and at t 2 When switching from cell B to cell C at any time, the terminal stays in cell B for t 2 -t 1 ....

Abstract

The embodiment of the invention discloses a mobile state estimation method and device of a terminal, electronic equipment and a storage medium, and the method comprises the steps: obtaining the residence time of the terminal in each NTN GEO cell in a non-ground network NTN GEO scene; and estimating the moving state of the terminal according to the relationship between the residence time and a threshold range, wherein the two end points in the threshold range are determined according to the radius ratio of the coverage radius of the NTN GEO cell to the coverage radius of the common land cell. According to the embodiment of the invention, the mobile state of the terminal is estimated by judging the relationship between the residence time of the terminal in each NTN GEO cell and the threshold range and combining the radius ratio of the coverage radius of the NTN GEO cell to the coverage radius of a common land cell; and the problem of inaccurate terminal movement state estimation caused by too large cell coverage radius in the NTN GEO scene is solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device, electronic equipment and storage medium for estimating a mobile state of a terminal. Background technique [0002] For 4G (the 4th Generation, fourth-generation mobile communication technology) LTE (Long Term Evolution, long-term evolution), the terminal can perform MSE (Mobility State Estimation, mobile state estimation) through a certain mechanism, so as to perform Parameter correction. For 5G (the 5th Generation, fifth-generation mobile communication technology) NR (New Radio, new air interface), the 4G mobile state estimation scheme is used as the basic scheme, that is, the terminal counts the number of cell selections performed by the terminal within a certain period of time , so as to estimate its mobile state. For 5G NTN (Non-Terrestrial Networks, non-terrestrial networks), some new features have been introduced, such as cells with ...
