0x147B GNSS CD DB Report
查看xtra数据的下载成功与否
做冷启动测试：
可以查看辅助数据的数据库状态， 来看辅助数据是否下载成功。这个可以如下看xtra数据的下载成功与否,或者如下方法:
用qcat搜过0x147B,
查看GpsEphMask和GpsAlmMask是否有数据:
GpsEphMask = 0x00000000 (# 0):[]
GpsAlmMask = 0x00000000 (# 0):[]
如果下载成功,如下:
GpsEphMask = 0x00201328 (# 6):[4,6,9,10,13,22,]
GpsAlmMask = 0x00FFFFFF (#24):[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,]
查看xtra数据下载成功
使用QCAT打开qxdm日志, 然后搜索0x147B, 在View->Parser View可以分析是否download XTRA

概念
CP ( Control _Plane控制面 )
传送控制信令的通道
通信设备之间的信息传递空中接口，粗略分为 PHY(L1,物理层) DDL(L2,数据链路层) NL(L3,网络层)
L1主要功能: 提供两个通信设备之间可靠的比特流的传送 ( 船本身 用来运货的 )
L2主要功能: 信道的复用 数据的封装 数据包的调度 ( 负责开船的 )
L3主要功能: 寻址 路由选择 连接的建立 控制 资源配置策略 ( 看门验码叫号的 )
接口协议不仅分层还要分面: 从信息处理的类型不同, 分为 用户面协议 和 控制面协议
UP 用户面 负责 业务数据的传送和处理
CP 控制面 负责协调和控制信令的传送和处理 两者是逻辑上的概念

常见问题
移动商业报警系统 WEA(Wireless Emergency Alerts)
【CMAS(Commercial mobile alert system)移动商业报警系统 WEA(Wireless Emergency Alerts)】
https://blog.csdn.net/aaa111/article/details/79361595 网页说明
WEA 是基于小区广播服务的，那它的接收也是和小区广播一样（手机端）它独有的地方在于要配置WEA 相关的mids（Message ID）或者说Channel ID 到modem
而Modem端的mids来源于代码，SIM卡，NV值等

GPS天线干扰排查
【QCAT 中 Displays > QCAT Sample > GNSS > GNSS RF Bp Amp Pga Gain Data QCAT-GNSS-天线干扰】
Bp Amp应该在90-350 min-max 否则就有干扰
