METHOD FOR DETECTING SIGNALING DOS TRAFFIC IN 3G WCDMA NETWORKS

摘要

PURPOSE: A signaling DoS traffic detection method in a mobile communication network is provided to detect signaling DoS traffic attack which causes mobile communication network error by a signaling message. CONSTITUTION: A packet filtering engine(100) classifies RAB(Radio Access Bearing) connection. An RAB connection detector(200) detects malicious RAB connection from the classified RAB connection. A signaling DoS(Denial of Service) detector(300) determines signaling DoS attack according to the calculated RAB connection.
