Enhanced Non-Seamless Offload for LTE and WLAN Networks

Non-seamless WLAN offload is a currently available approach to the data explosion issue in cellular networks without requiring new hardware and functional deployment on network sides. In this article, we propose two enhanced offloading methods that guarantee session continuity for non-seamless WLAN offload. We describe how the proposed methods manipulate multi-radio (LTE and WiFi) interfaces to maintain IP sessions in the dynamics of available radios. We present a performance analysis that studies the throughput and energy consumption of smart devices.
