LTE-A与WiMax2网间切换的研究与实现

随着通信技术的迅速发展,在无线通信领域,无论是GSM,TD-SCDMA,WCDMA,CDMA2000,WLAN,LTE,还是LTEA、WiMax2等都有各自独立的优缺点,任何一种无线通信技术都不能独立支持所有业务的发展,多种技术的共存与融合将会成为未来移动通信网络发展的趋势。基于LTE-A(TDD)和WiMax2网络融合的可行性研究成果,提出了一种异构网络下基于相对信号强度,滞后差值和触发时长作为判断准则的垂直切换算法。最后,采用MATLAB仿真工具,建立LTE-A(TDD)与WiMax2混合组网的仿真模型,来验证该算法的可行性。

Research and Implementation of Vertical Handover between LTE-A and WiMax2

With the rapid development of communication technology the standards, such as GSM, TD-SCDMA, WCDMA, CDMA2000, WLAN, LTE or LTE-A, WiMax2, etc., all have their own advantages and disadvantages in the field of wireless communications, Any kind of wireless communication technology cannot support the development of all communication services; moreover, the coexistence and fusion of various technologies will become future development tendency. This paper based on the feasibility research results of studying LTE-A (TDD) and WiMax2, and then we propose a vertical handover algorithm which is based on the relative signal strength and use HOM and TTT as criterions in heterogeneous network. Finally, through the established simulation model of the LTE-A (TDD) and WiMax2 hybrid networking by Matlab, and verified the feasibility of the algorithm.
