Abstract
Nowadays, the current trend is to integrate WiFi with Long Term Evolution (LTE) networks in order to meet the growing demand for huge amounts of data traffic and provide ubiquitous coverage. Seamless mobility between heterogeneous networks with the required Quality of Services (QoS) provisioning for Mobile Terminals (MTs) is one of the most challenging issues while considering LTE-WiFi integration. Several studies reported in the literature have addressed the vertical handover (VHO) challenges between the two access networks. However, none of these approaches provides the MTs with the required QoS without adding a new entity or increasing the signaling cost. Thus, this paper proposes a VHO decision algorithm between LTE-WiFi heterogeneous networks. A performance study is conducted which compares the proposed approach with the WiFi First (WF) approach. Results show that the proposed approach can support QoS and reduce Wi-Fi blocking probability without adding any new entities to the infrastructure or increasing signaling costs. Also, the proposed approach outperforms existing solutions in terms of delay and signaling costs, while providing the MTs with the required QoS.
目前的趋势是将WiFi与LTE (Long Term Evolution,长期演进)网络相结合,以满足日益增长的海量数据流量需求,并提供无处不在的覆盖。在考虑LTE-WiFi集成时,异构网络之间的无缝移动性以及为移动终端提供所需的服务质量(QoS)是最具挑战性的问题之一。文献报道的一些研究已经解决了两个接入网之间的垂直切换(VHO)挑战。然而,这些方法都不能在不添加新实体或增加信令成本的情况下为mt提供所需的QoS。为此,本文提出了一种LTE-WiFi异构网络间的VHO决策算法。进行了性能研究,将所提出的方法与WiFi优先(WF)方法进行了比较。结果表明,该方法在不增加任何新的实体或增加信令成本的情况下,能够支持QoS并降低Wi-Fi阻塞概率。此外,所提出的方法在延迟和信令成本方面优于现有的解决方案,同时为mt提供所需的QoS。
