The method comprises the following steps: determining a target LTE cell corresponding to a to-be-evaluated NB-IoT cell, wherein the target LTE cell and the NB-IoT cell belong to cells with the same frequency band and the same system; calculating a difference factor used for performing coverage conversion between the cell pairs; and selecting a corresponding coverage conversion algorithm based on the difference factor, the acquired cell parameter corresponding to the NB-IoT cell and the cell parameter and the cell measurement value corresponding to the target LTE cell, and obtaining the receiving level of the NB-IoT cell. According to the embodiment of the invention, the method comprises the steps: determining a target LTE cell with the same frequency band and the same system as a to-be-evaluated NB-IoT cell; combining the cell parameters of the target LTE cell and the NB-IoT cell; according to the embodiment of the invention, the coverage condition of the NB-IoT network is determined based on the coverage condition conversion mapping of the LTE cell by acquiring the cell measurement value of the target LTE cell and considering the difference factor used for carrying out coverage conversion between the NB-IoT cell and the target LTE cell according to the cell measurement value of the target LTE cell.
