1. 必须在 full start 冷启动 才会去请求 AGPS(SUPL) , 清空位置信息
$PMTKEPH,0*43 // 没有星历，需要SUPL辅助
$PMTKEPH,99,1,2,3,4,5,6,7,8,9,1 // 有足够实收星历，不需要SUPL辅助
2. 可以在测试 SUPL 可以关闭 EPO 和 NPL
关闭EPO: 工模 > Location > YGPS > Inform ACTION > 【Enalbe EPO(Need Restart)】(disable) 【Enalbe QEPO(Need Restart)】(disable)
关闭NPL for SUPL: 工模 > Location > LocationEM > AGPS > 【Use NPL Settings to SUPL】(disable) (打开NPL 会变为Framework优先 可能导致优先使用 standalone mode 而不触发AGPS)
3. 需要给 non-framework app授予allow loction all the time 的权限
4. 如果需要 dedicated APN 那么必须在 在 工模下打开 【Allow SUPL dedicated APN】
5. 如果需要SUPL 需要使用 .cer证书 (.pem 需要转为 .cer证书 ) 进行加密TLS 通信 那么需要 确保当前 LOG 打印 ca_enable=1 是打开的
<up_setting ca_enable="true" >
手机没有开启ca_enable，证书在连接supl server时并不会因为证书匹配失败导致连接失败。
并且在实验室测试时 需要打开工模AGPS 下的 【Allow AGPS Certificates for Lab Test】(enable) 选项 匹配的Log是 sdcard_cert=1

解决: 在MTK 的AgpsApn.java 文件中修改加入一行 /vendor/mediatek/proprietary/packages/services/LPPeService/src/com/mediatek/location/agps/apn/AgpsApn.java
mNetReqInternet = nrBuilder
.removeCapability(Networkcapabilities.NET_CAPABILITY_NOT_VPN) //增加这一行 使得 AGPS 允许使用VPN网络
.removeTransportType(NetworkCapabilities.TRANSPORT_CELLULAR)
双SIM卡，发起SUPL请求的消息是SIM0,但在SIM0中却发现了 SIM1的 IMSI电话号码，
修复措施: 打开 ENABLE_ACTIVE_SIM_EMERGENCY_SUPL 对应 /packages/apps/CarrierConfig/res/xml/vendor_asia.xml
<carrier_config cid="1894" name="SoftBank" unique_rule_id="SoftBank">
<boolean name="gps.enable_active_sim_emergency_supl" value="true" />
