5.故障定位与处理
Troubleshooting and Handling
本章主要阐述如何对 CPE 进行故障处理，可以从两个方面对 CPE 进行故障问题定位，
分别是通过 LTE 连接状态定位问题和通过日志分析定位问题。
This chapter mainly described how to troubleshooting, we can get the suspicious point from
LTE connection status and log analysis .
5.1.LTE 连接状态分析
Check LTE Connection Status
当 CPE 发生上线故障时，可以通过获取健康节点的值来分析 CPE 上线故障，1.3 章节
中获取的 Status Cause 就是该节点的值，健康节点可以显示的过程定义如下：
When CPE attach failed, you can get the reason why CPE attach failed through HealthCheck
value which illustrated in chapter 1.3, the value of the HealthCheck is defined as follows:
i. InitialModule
ii. USIMChecking
iii. ConfigChecking
iv. Detaching
v. NetworkSearching
vi. Attaching
vii. PDNActiving
viii. Established
当某个过程正常完成时，会在该过程名称后面加上 Success 的标示，如果该过程出
错，则在该过程名称后面加上出错原因。以下三个小节分别对容易出错的三个过程
（USIMChecking、NetworkSearching、Attaching）进行了错误分析。
When a process is normally complete, “success” will be added to tail of the that step , else a
error cause will be added . The following three chapters define the detail of the possible error in in
step USIMChecking, NetworkSearching, and Attaching.
5.1.1 USIM Checking 错误分析
USIM Checking Error analysis
该小节主要是对 USIM 的检查，如果检查不通过，则会产生 CME Error。CME Error 的
定义参考附录 C.
