Billing attack detection and prevention in mobile communication network

摘要

The IP-based value-added service and data service develop quickly and become diversified with the evolution of mobile communication network. More and more services are chargeable and billing occurs when mobile subscribers access them. Billing attack to the IP/data service can cause great loss to the telecommunication operator and customer. Traditional fraud detection technologies focus on anomaly analysis on call detail record (CDR) and fraud detection which faces much challenge in detecting the billing attack in the mobile communication network. In this paper, a billing attack detection and prevention technology is proposed which combines the identity authentication, key process monitor and anomaly service traffic identification. An attack detection and prevention system is designed and implemented to inspect the fraudulent traffic and alarm or block the billing attempt.
