Mobile communication data flow anomaly monitoring system and method

The invention relates to a mobile communication data traffic abnormality monitoring system and method, and the system comprises a traffic obtaining module which is used for obtaining a total data traffic monitoring value in a to-be-monitored communication equipment cluster in a preset period, and is also used for obtaining a sub-data traffic monitoring value of each piece of communication equipment in the to-be-monitored communication equipment cluster in the preset period; a flow analysis module which is used for carrying out superposition processing on the sub-data flow monitoring values ofeach communication device in the to-be-monitored communication device cluster to obtain a total data flow calculation value of the to-be-monitored communication device cluster, carrying out comparative analysis on the total data flow calculation value and the total data flow monitoring value to obtain a comparison result, and judging whether the mobile communication data traffic in the to-be-monitored communication equipm
