Abstract
The present invention provides a method and a device for determining missed neighbor cells. The method comprises the steps of extracting the corresponding key information out of the information corresponding to an abnormal event; calculating the CFN difference value between a cell with the occurrence of the abnormal event and a serving cell based on the key information; and matching the CFN difference value with preset cell CFN difference records according to the matching information.
