A cell reselection method performed by comprising: determining at least two frequency priority rankings carried in a received system message, wherein the at least two frequency priority rankings comprise a first frequency priority ranking corresponding to a speed of the terminal that is higher than a preset speed and a second frequency priority ranking corresponding to a speed of the terminal that is smaller than the preset speed; each frequency priority ranking comprises a priority of a frequency used by a high-speed-railway dedicated network and a priority of a frequency used by a long-term evolution, LTE, network; and in the first frequency priority ranking, the priority of the frequency used by the high-speed-railway dedicated network is higher than that of the frequency used by the LTE network, and in the second frequency priority ranking, the priority of the frequency used by the high-speed-railway dedicated network is lower than that of the frequency used by the LTE network; selecting a target frequency priority ranking from the at least two frequency priority rankings according to the speed of the terminal by: selecting, in response to the speed of the terminal being greater than the preset speed the first frequency priority ranking as the target frequency priority ranking; and selecting, in response to the speed of the terminal being smaller than the preset speed, the second frequency priority ranking as the target frequency priority ranking; and selecting, from multiple scanned frequencies, a frequency with a highest priority in the target frequency priority ranking as target frequency from, and selecting one cell with best signal quality from multiple cells corresponding to the target frequency for residence. determining at least two frequency priority rankings carried in a received system message, wherein the at least two frequency priority rankings comprise a first frequency priority ranking corresponding to a speed of the terminal that is higher than a preset speed and a second frequency priority ranking corresponding to a speed of the terminal that is smaller than the preset speed; each frequency priority ranking comprises a priority of a frequency used by a high-speed-railway dedicated network and a priority of a frequency used by a long-term evolution, LTE, network; and in the first frequency priority ranking, the priority of the frequency used by the high-speed-railway dedicated network is higher than that of the frequency used by the LTE network, and in the second frequency priority ranking, the priority of the frequency used by the high-speed-railway dedicated network is lower than that of the frequency used by the LTE network; selecting a target frequency priority ranking from the at least two frequency priority rankings according to the speed of the terminal by: selecting, in response to the speed of the terminal being greater than the preset speed the first frequency priority ranking as the target frequency priority ranking; and selecting, in response to the speed of the terminal being smaller than the preset speed, the second frequency priority ranking as the target frequency priority ranking; and selecting, from multiple scanned frequencies, a frequency with a highest priority in the target frequency priority ranking as target frequency from, and selecting one cell with best signal quality from multiple cells corresponding to the target frequency for residence.
