Abstract: A network anomaly diagnosis device and a method thereof are provided. The network anomaly diagnosis device includes a data analyzer configured to receive a control plane message for a service provided to a terminal by a mobile network operator (MNO) from the terminal and analyze the control plane message, a database configured to collect results of analyzing control plane messages for services provided to the terminal by different MNOs including the MNO from the data analyzer and store the result of analyzing the control plane message for each MNO, and a controller configured to compare the result of analyzing the control plane message of the MNO at the data analyzer with the result of analyzing the control plane message for each MNO, the result being stored in the database.
