摘要

如今，移动数据流量呈爆炸式增长，它可以加载到运营商的核心网络。为了减少负载，3GPP提出了本地IP访问(local IP access, LIPA)和选择IP流量卸载(selective IP traffic offload, SIPTO)等卸载方案。对于卸载算法，有许多基于LIPA/SIPTO的相关工作，但也有一些研究工作超出了LIPA/SIPTO。然而，这些相关工作并没有考虑到网络的利用。为此，本文提出了一种基于网络利用率和卸载偏好来确定卸载比例的新型卸载算法。通过仿真验证了该算法的有效性。

Novel LIPA/SIPTO offloading algorithm according to the network utilization and offloading preference

Today, mobile data traffic explosively increases and it can be load to operator's core network. To reduce the load, 3GPP proposes the offloading solutions such as local IP access (LIPA) and selected IP traffic offload (SIPTO). For offloading algorithm, there are many related works based on the LIPA/SIPTO but some research works beyond the LIPA/SIPTO. However, these related works don't consider network utilization. Thus, this paper proposes a new offloading algorithm that decides the offloading ratio based on the network utilization and offloading preference. By the simulation, we show the performance of the proposed algorithm.
