== Getting MCC, MNC, LAC and CI ==
You need to provide your position estimate to supl server as
cellular transmitter tower ids. One way to get them is to
go to the AT-command interpreter in your phone and ask for them:
at+cops?
+COPS: 0,2,"24405",2
OK
at+creg=2
OK
at+creg?
+CREG: 2,1,"59E2","31B0"
OK
at+creg=0
OK
==> you get needed values
MCC = 244
MCN = 05
LAC = 0x59e2
CI = 0x31b0
小米手机可以通过键盘输入 *#*#4636#*#* 查询 , 或者用cellular-z之类的app也可以读取.
