摘要
随着移动智能终端产品的丰富化和人们对无线网络资源需求的急需增长,第三代移动通信技术(Third Generation Communication Technology,3G)在我国得到了迅速发展和普及。WCDMA作为3G技术的其中之一,是由3GPP(The 3rd Generation Partnership Project)国际标准制修订组织提出,目标是实现由2G网络到3G网络的平滑过渡,保证未来技术的后向兼容性,支持系统间的漫游和兼容性。通过对WCDMA增强型高速分组接入技术的解读,分析采用的编码方式和峰值计算方法,消除人们对网络峰值21Mbps和42Mbps的错误理解。着重对3GPP TS 34.121-1中的9.2.1H测试用例进行分析,同时对其理论测试数据和现实网络测试数据进行比较分析,得出两者的差异性。
Due to the intel igent mobile terminal products diversification and wireless network resources re-quirement increased,the third generation mobile communication technology (3G) has been rapid developed and popularized in China.WCDMA is one of 3G technology,which is proposed by the 3GPP standards orga-nization.The goal is to achieve the 2G network to the 3G network transition smoothly,ensure backward com-patibility with future technologies,support different systems roaming and compatibility.Through interpreting WCDMA enhanced by high-speed packet access technology,analyzing the encoding and peak speed cal-culation method is to eliminate the misunderstanding between 21Mbps and 42Mbps.Special y analysis on 3GPP 34.121-1 test case 9.2.1H is to get the difference from its theoretical and practical network test data comparison.
