The present disclosure provides a cell access method and device. The method is applied to a base station and can include generating RRC information that is used for instructing a terminal to determine a speed state of the terminal and a cell type of a cell to be accessed. The method can further include sending the RRC information to the terminal, so that the terminal determines the speed state and the cell type according to the RRC information and initiates access to the cell to be accessed when determining that the speed state and the cell type meet a preset cell access condition.
