This document is compiled to guide the network optimization engineers to solve the call drop problem, to reduce the call drop rate, and to improve the quality of the network. It also introduces ways to evaluate, test, analyze and solve the call drop problem. In addition, it also includes some typical cases. In the actual network optimization activities, handover and call drop are strongly related. In most cases, handover failure would lead to call drops. For this kind of call drops, you may refer to the guidebook for call drops caused by handover. This document mainly focuses on call drops which are not caused by handover failures.
