专用的频谱占用率监测为频率规划和管理提供了重要的信息，但往往不能反映频谱占用率的共性。作为补充，模型方法可以用来描述和比较相似条件下的占用情况。时间序列分析已被应用于无线电频谱占用的建模。本文将不同的时间序列模型划分为不同的占用模式。以全球移动通信系统（GSM）频段的占用分析为例。
While dedicated spectrum occupancy monitoring provides vital information for frequency planning and management, it usually cannot tell the common properties in spectrum occupancy. As a complement, the models approach can be used to describe and compare the occupancy situations under similar conditions. Time series analysis has been applied to modeling the radio spectrum occupancy. This paper categorizes different time series models to different occupancy patterns. Occupancy analysis of the Global System for Mobile communications (GSM) band is given as an example.
