摘　　要：本文通过采用GSM900功率控制参数精细优化的措施,有效控制上、下行发射功率。在保证一定C/I的基础上,根据每个小区的底噪电平和保护电平,优化设置上下行发射功率,达到降低带内干扰、改善无线性能、降低掉话率的目的。In this paper an optimization method of GSM900 power control parameters was put forward to control uplink and downlink transmission power effectively. Given some C/I and considered the level of background noise and guard for every cellular, the uplink and downlink transmission power were set accurately in order to reduce interference in-band and improve wireless features. Then call dropping rate was changed better.

关 键 词：功率控制 参数 底噪 掉话率
