各位大侠，以下英文术语是什么意思？

Active set cell count
cells added to active set
cells removed from active set
total received Throughput

你得先说明下是在哪个设备里看到的  cell可以用在很多地方

Active set cell count :激活集小区统计
cells added to active set：小区加入激活集
cells removed from active set ：小区移除激活集
total received Throughput：接收到的总吞吐率（不太确认，知道的指点下）

这几个术语是在用OPNET仿真工具 仿真切换时用到的 麻烦各位说下 谢谢

还有人知道吗
