COMMUNICATION METHOD AND APPARATUS

This application pertains to the field of communication technologies, and provides a communication method and apparatus, to implement false base station detection. A false base station may attack a terminal in a denial of service manner, and consequently, the terminal cannot access the false base station after selecting the false base station, in other words, the terminal fails to set up a connection to a cell. In this case, if a first message indicates that a first terminal fails to set up a connection to a cell, it may be determined, based on the first message, that a false base station attack exists in the cell, to implement false base station detection.
