摘要
本文针对LTE和WiFi共存的情况，提出了一种新的QoE (Quality of Experience)优化机制，实现了从LTE到WiFi的流量分流。首先，分别分析了LTE和WiFi的吞吐量模型。然后引入用户满意度函数来衡量质量质量。提出了在保证WiFi网络QoE的前提下最大化LTE网络QoE的最优问题，并通过变换和简化求解。仿真结果表明，流量分流可以显著提高LTE网络的QoE。
QoE Optimization for Traffic Offloading from LTE to WiFi
In this paper, a novel QoE (Quality of Experience) optimization mechanism is proposed for the coexistence between LTE and WiFi networks, where traffic offloading is enabled from LTE to WiFi. Firstly, the throughput models of LTE and WiFi are analyzed, respectively. And then the users' satisfaction function is introduced to measure QoE. An optimal problem that maximizing the QoE of LTE network with guaranteeing the QoE of WiFi network, is formulated and solved by transformation and simplification. Simulation results indicate that traffic offloading can greatly improve the QoE of LTE network.
