摘要
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。
With the rapid development of communication technology, in the field of wireless communication, any kind of wireless communication tech- nologies are not independently support to all business, whether it is GSM, TD -SCDMA, WCDMA, CDMA2000, WLAN, LTE, LTE -A, or WiMax2, all they have respective advantages and disadvantages, the coexistence and integration of various technology will become the trend of the development of mo- bile communication network in the future. It is based on the feasibility study LTE-A （TI）D） and WiMax2 network in this paper, and puts forward a ver- tical handoff algorithm based on the criterion such as relative signal intensity, delay difference and triggering time in a heterogeneous network. Finally, using MATLAB simulation tools it establishes the simulation model in a hybrid network between LTE-A（TDD） and WiMax2 to verify the feasibility of this algorithm.
