【摘要】 20世纪90年代以来,人们开始选择方便、移动性好无接入技术来取代有接入技术决“最后一公里”问。随着WLAN、WPAN等无低速网络技术产生,人们迫切需要一种能在高速移动状态下进行高速传输宽带网络技术。1999年,IEEE成立了IEEE802.16工作组来专门研究宽带无接入技术规范。2004年10月1日,IEEE802.16d发布,并发布了IEE802.16e作为移动性补充,这两种标准合为IEEE802.16-2004。在此基础上,供应商互联互通组织了基于802.16标准无域网技术行业为WiMax技术。随着时间推移,目前研究人员在WiMax系统仿真工具、网络规建设上取了一定成果,也出了一些WiMax网络技术分析方法,但在WiMax网络建成后网络通信性能优分析和安全性能改进上还未出具体方案。本文在总了基于OSI模型WiMAX技术性能研究分析方法基础上,使用将关键性能与实际参数合方法出了衡量WiMax网络通信性能关键指标KPI,并据WiMax系统与3G融合趋势与似性,出了关KPI参考值。并将KPI与用户投诉、网管数据一起作为WiMax系统优工作数据来源,然后据这些数据来源出了应优方案;另一方面据基于OSI模型WiMax技术性能研究分析方法分析了WiMax系统所面临安全威胁和系统漏洞,并在此基础上出了应安全决方案,对WiMax技术安全性能改进出了自己建议。更多还原

【Abstract】 Since the 1990s, the people start to choose conveniently, the mobilized good tether less access technology to substitute for wireless access technology solution“last kilometer”question. Along with WLAN, WPAN and so on wireless low speed networking production, the people need one kind to carry on the high speed transmission under the high-speed motion condition urgently the broadband network technology. In 1999, IEEE established the IEEE802.16 work team to study the broadband wireless access technology standard specially. On October 1, 2004, IEEE802.16d issued that and had issued IEE802.16e takes the mobilized supplement, these two kinds of standards are called are IEEE802.16-2004. Based on this, the supplier interconnection intercommunication organization named based on 802.16 standard wireless metropolitan area network tech industry names is the WiMax technology. With the lapse of time, the researchers in the WiMax system’s emulation tool and in the network planning construction have yielded certain result at present, proposed some WiMax networkings analysis methods, but after the WiMax network completes in the network service performance optimization analysis and safety performance improvement has not proposed the concrete plan. This article in summarizing based on the OSI model’s WiMAX technical performance research analysis method’s foundation, has used the method which unifies the essential performance and actual parameter to propose weighs the WiMax network service performance key indicator KPI, and according to the WiMax system and 3G integration trend and similarity, has given the related KPI reference value. And KPI and user suit and network management data as the WiMax system optimization data origin of work, then has given together according to these data origins the corresponding optimization plan; On the other hand according to analyzes the security threat and system loophole which based on the OSI model’s WiMax technical performance research analysis method the WiMax system has faced, and has given the corresponding secure solution based on this, put forward own proposal to the safety performance improvement of WiMax technology.更多还原
