高通平臺信號強度和質量的log過濾

1、對於高通平臺分析log的工具天然是QXDM和QCAT，對於信號強度和信號質量的查看是分析通話、短信等故障必看的項目，而對於不一樣的網絡制式，所過濾的標籤也不同

一、WCDMA

Thank you for consulting with us!

You can check log packets 0x4186,4176,0x4023 for checking the signal quality and signal strength of WCDMA.

For more information on log packets you can refer document 80-V2708-3.

二、LTE

Dear Customer,
For LTE, please check log packet 0xB193 for RSRP/RSRQ/RSSI.

三、CDMA

You can filter "rx agc" in 1x search message log to see RSSI and ECIO.

One good way is to filter QMI messate with keyword "strength". Then you can refer to frameworks\base\telephony\Java\Android\telephony\SignalStrength.java -> getLevel() to know the qualilty about each RAT.

四、GSM

0X5A6C

五、TDSCDMA

You could check the 0xD00A. In where, ASET is service sell, MSET is N cells.
