摘　　要：影响TD-SCDMA掉话率的主要原因有干扰,邻区切换关系错配、漏配,弱覆盖,小区越区覆盖等,本文从"小区更新(CELL_UPDATE)"的角度出发,判断TD-SCDMA掉话的具体原因并做相应优化调整,有效降低了TD-SCDMA网络的掉话率。Dropped calls in TD-SCDMA are mainly caused by radio interference, data error in neighbor cell configurations, bad coverage, over-coverage and so on. By analyzing the ＂cell_update＂ process, we achieve to identify the true reasons for （different） drop calls before taking measure to make optimization which finally benefit in a decrease in the TD-SCDMA drop call rate.
