摘　　要：根据湍流尺度分析中的对数无限可分级串方法(LIDC),对从某移动运营商处获取的无线分组网络流量进行了多尺度行为分析,以GPRS为例,发现现网GPRS流量符合对数无限可分级串框架,并由此对无线分组流量数据进行了深入的特性分析.结果表明,LIDC方法在分析无线分组网络流量的多尺度行为方面非常有效.该方法不仅在全尺度范围内能刻画网络流量的尺度特性,而且能确定出某一尺度下的有效分析范围.同时,经过该分析框架分析表明,无线分组网络流量中的尺度保持了幂律关系、单一尺度及尺度不变性等特点.According to the log-infinitely divisible cascades framework introduced from the analysis of turbulence scale, this thesis analyses the multi-scale character of wireless-packet network traffic gathered in mobile operations＇ network, sampled with general packet radio service （GPRS）, found that the actual GPRS traffic conforms to the log-infinitely divisible cascades framework; Further more aspects of analysis on wireless-packet flow data are accomplished based on this method, found that log infinitely divisible cascades （LIDC） is very effective on analysis of wireless-packet traffic multi-scale character. The LIDC can depict the scale-character in the full-range scale of traffic, as well as it can differentiate the valid range within a specific scale. And more, based on this framework, this thesis＇s analysis shows that the scale of wireless-packet traffic complies with power-law, mono-scale and scale- invariance.
