Unicom 3 g wireless card for base station positioning-CodePudding

In the embedded devices using the usb 3 g wireless card online
Now I'm going to get LAC and CID, base station positioning
Via a serial port to the at command: the at + creg=2; The at + creg? Two days instruction
Results: 90 cdc0d + CREG: 2, 1, D700C,
D700C should be LAC, I should check the LAC is 16 online, but I must be more than 16, obviously can't locate to the base station,

Oh, by the way, my card is unicom 4 g wireless card, but when the 3 g network card dial-up can use normal dial-up,
And I take 4 g phone card when card use, also can dial-up Internet access, but without sending an instruction to the at + creg=2, can be performed at + creg=1.

Realization of base station location, need to support the operators, not simple can get from the AT command, this is I understand the situation in the future!

Have no more than two years to make this thing, for your reference,

Mobile phones can locate, you mean the map is on the phone software, or other?
Whether can locate, actually has very little to do with card, card, identification is a dongdong, the function of the mobile phone module itself, you can judge the position relative to the base station, just provide carrier or module, or conditional offers users use,

There are three kinds of positioning in general:
1. Base station lac, cid position an approximate location, such as mobile phones in indoor positioning
2. By GPS, such as mobile phone positioning outdoors
3. Through the network, such as PC network access point

Now I just want to get the 3 g card of lac and the cid, and then realize positioning
