在移动通信中,掉话是指在分配了话音信道(TCH)后,由于某种原因,使呼叫扔掉或间断,正常通话无法进行的现象。TCH掉话主要有三种类型:射频扔掉掉话(即无线链路缺点掉话)、切换失败掉话、Lapd掉话。

(In mobile communication, call drop refers to the phenomenon that after the voice channel (TCH) is allocated, the call is dropped or interrupted for some reason, and the normal call cannot be carried out. There are three main types of TCH dropped calls: RF dropped calls (that is, wireless link defect dropped calls), handover failure dropped calls, and Lapd dropped calls.)
