TERMINAL DETECTION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To detect an unauthorized or abnormal terminal.SOLUTION: The system detects a terminal 11. A property information comparison unit 17 compares first communication property information showing a communication property of a previously defined terminal with second communication property information of the detected terminal. When the second communication property information is different from the first communication property information as a result of a comparison result, an unauthorization/abnormality determination unit 18 recognizes the detected terminal as an unauthorized terminal.SELECTED DRAWING: Figure 1
