Part of LTE's new architecture is an evolved packet core. Although this will provide various critical advantages, it may on the other hand expose telecom networks to IP-based attacks. In this paper, we propose a distributed architecture on the LTE network that is secure by mitigating the spam-flooding attack, efficient by solving the over dimensioning problem caused by the centralized architecture, and cost-effective by utilizing ‘off-the-shelf’ low-cost hardware in the distributed nodes.
