PURPOSE: An abnormal call detail record (CRD) information analyzing system and a method thereof are provided to enable early detecting of abnormal communication resulting in a charging resulting attack or an attack precluding the use of a terminal. CONSTITUTION: A CDR information reference part (100) comprises a collecting and parsing part and a first reference part. The CDR information reference part generates abstract CDR information by parsing CDR information. An abnormal communication detection part (200) receives the abstract CDR information. The abnormal communication detection part detects an abnormal voice call and an abnormal message based on the abstract CDR information. The abstract CDR information includes information about the kind of communication service, a caller, a receiver, communicating time, whether communication is connected and additional information.
