I don't know if this is a technical news group, but I'll ask my question
here.

I have a mobile phone and am after the AT command for retreiving the cell
site area that most phones are cabiable of displaying. Does anyone have an
idea? The nearest I have found is to retreive the current network operator,
I have looked through several mobile AT command set manuals...but I must not
be looking at or for the right thing.

Robert.

I presume you're talking about the cell geographical name that's
sent out on cell broadcast channel 50 (or maybe 200) by some
operators in some countries.

Does your phone support text-mode ("AT+CMGF=1") across the
serial interface? It's easier for you if it does, since you
won't need to decode PDU-mode responses.

A couple of GSM 07.05 commands are required: "AT+CMNI" and
"AT+CSCB". Then each new cell camped on will result in an
unsolicited "+CBM: " dump to the serial port, containing the
cell name.

The composite command

AT+CNMI=1,0,2,0,1;+CSCB=0,"50,200","0-15"

should work from most phones.

Let me assure you, it took me a long time to work it out in the
first place :)
