A cell access method includes determining a cell type of a first cell as a cell served by a high-speed-railway dedicated network or a cell of an ordinary Long-Term Evolution network. When determining the cell type as the cell served by the dedicated network, a first system message is configured and includes a first information unit indicating a number of equivalent cells, and sent to a terminal for determining, according to the first system message, that the cell type of the first cell is the cell served by the dedicated network. Upon determining a terminal movement state meeting preset access conditions of the cell served by the dedicated network, an access to the first cell is initiated. As such, the accuracy of terminal movement state can be predicted in accordance with the number of equivalent cells to the first cell, and the accuracy of cell access can be further improved.
