An LTE-Based VPN for Enhancing QoS and Authentication in Smallcell Enterprise Networks

摘要

In this paper we deal with VPN implementation in Smallcell enterprise networks. Equipped with USIM cards, these access points represent the end points of communication tunnels. First, an authentication scheme is proposed. It reduces the exchanged messages between users and the LTE core and permits to avoid unnecessary LTE re-authentication. Also, an aggregation mechanism using LTE features is proposed reducing the communication costs.
