and under the condition that the first target sub-parameter is larger than a fourth preset threshold value and smaller than a third preset threshold value, determining the moving state of the terminal to be an original moving state, wherein the original moving state comprises a high-speed moving state or a low-speed moving state.
In the embodiment of the invention, the mobile state of the terminal in the connected state can be determined by the beam switching frequency (namely, the number of times of SSB switching), if the number of times of SSB switching is greater than or equal to N2 (the third preset threshold value) in the set target time, the terminal is judged to be in a state of high-speed movement, if the number of times of SSB switching is less than or equal to M2 (the fourth preset threshold value), the terminal is judged to be in a state of low-speed movement, if the number of times of SSB switching is greater than or equal to M2 and less than N2, the original mobile state is kept unchanged, if the number of times of SSB switching is greater than M2 and less than N2, the mobile state of the terminal is determined to be in a state of high-speed movement, if the number of times of SSB switching is greater than M2 and less than N2, and the mobile state of the terminal is determined to be in a state of low-speed movement.
In the embodiment of the invention, the mobile state can be determined by the TRS frequency offset turnover frequency for the terminal in the connected state. If the TRS frequency deviation turnover number is greater than or equal to N3 (the third preset threshold value) in the set target time, the terminal judges that the terminal is in a high-speed moving state, if the TRS frequency deviation turnover number is less than or equal to M3 (the fourth preset threshold value), the terminal judges that the terminal is in a low-speed moving state, if the TRS frequency deviation turnover number is greater than M3 and less than N3, the terminal keeps the original moving state unchanged, if the terminal is in a high-speed moving state before the moving state judgment, the TRS frequency deviation turnover number is greater than M3 and less than N3, the moving state of the terminal is determined to be in a high-speed moving state, if the terminal is in a low-speed moving state before the moving state judgment, and the TRS frequency deviation turnover number is greater than M3 and less than N3.

And after the terminal reselects or switches to a target cell, if the target cell is a high-speed cell, the mobile state of the terminal is redetermined and is sent to second network side equipment, wherein the second network side equipment is network side equipment corresponding to the target cell.
In the embodiment of the invention, after reselecting or switching the cell corresponding to the first network side device to the target cell, if a system message carrying a high-speed identifier and sent by a second network side device corresponding to the target cell is received, the mobile state of the terminal is redetermined and reported to the second network side device.

and if the mobile state of the terminal sent to the first network side equipment is a high-speed mobile state and the mobile state of the terminal in the target cell is determined to be a low-speed mobile state, the mobile state of the terminal is determined to be a high-speed mobile state again.
Here, after the mobile state of the terminal in the cell corresponding to the first network side device is a high-speed mobile state and is switched or reselected to the high-speed cell, if the mobile state of the terminal in the high-speed cell is determined to be a low-speed mobile state, the mobile state of the terminal is still determined to be a high-speed mobile state at this time, that is, the mobile state of the terminal is still in the area covered by the high-speed private network.
According to the method provided by the embodiment of the invention, under the condition that the message containing the high-speed identifier is received from the first network side equipment, the terminal can quickly determine the mobile state of the terminal according to the relation between at least one of the change times of the SSB index, the SSB switching times, the TRS frequency deviation turning times and the TRS time-frequency resource change times in the target time and the preset threshold value.
