A method includes: extracting a data value of receiver address field from a short message; wherein the short message sent by the short message center includes receiver address field, and the data value of the receiver address field includes the receiver's MSISDN; if the short message does not include the receiver address field or the data value is not local MSISDN such as the MSISDN of the receiver terminal, determining the short message as a fake base station short message. The MSISDN used in the present disclosure is an existing feature of the sender terminal and the receiver terminal without requiring the user to perform additional operations. Moreover, neither the short message center nor the receiver terminal needs to acquire the preset cryptogram in the gateway. Therefore, the present disclosure accurately detects a fake base station short message without requiring the user to perform additional operations.
