WiMax System Analysis And Optimization Based On OSI/RM

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.
