关于切换技术解决3G网络融合问题的综述

通过对无线通信网络的体系结构,运营方式,切换技术实现细节等方面的分析和研究,研究和探讨异构网络之间的切换技术,最终提出一个面向下一代无线通信网络的新型的基于IP的综合切换(Integrated Handover,IH)框架。IH技术的最终目标就是要解决移动通信网络中因网络异构、资源开销瓶颈等影响,成功地实现全球无线网络覆盖范围的低时延、高带宽、宽切换域、开销低和QoS保证的不同网络间顺畅的无缝切换。

Research on the Strategy of IH for the Third Generation Wireless Network

The conception of cellular is a very important in the field of wireless communication network. Communication services are provided by wireless overlay network with all different levels of cellular areas in the geographical region in current wireless networks, furture wireless and mobile communication also maybe utilizes this cellular technology. So, the handover procedure must be needed if only adopting cellular structure's wireless and mobile networks. With development of wireless communication technology, some new services and requirements will be brought forward in the furture. High-bandwidth, personalized, intelligent and mobility will be a trend of the furture communication. How to handover between heterogeneous RANs because of the user's roaming and the choice of new service is one of the key technologies to be solved. In this paper, a solution named IH(Integrated Handover) is proposed, which is a new handover mechanism based on IP for the next generation wireless network including fixed and mobile communications', and emphasis is on the discussion of conception, principium and implement mechanism of the IH based on IP layer, including IH prototype, components of IAH system, trigger parameters and so on.
