Dear all
 
Would  you please tell me how to get a cell ID of GSM network by using AT
command for GSM MODEM? I am using Siemens S45 connecting to PC running
Windows XP. Thank you.

    AT+CREG=2
 
and then
 
    AT+CREG?
 
This should give you a result like:
 
    +CREG: 2,1,"1030","639E"
 
Working through the 4 returned values, the "2" reflects the
current "+CREG" setting (2 means "Enables unexpected network
registration and location information messages" ), "1" indicates
that the phone is registered with the network, "1030" is the
Location Area Code (LAC) in hex (4144 decimal), and "639E" is the
CellID (CI) in hex (25502 decimal).
 
If the cell name itself is being broadcast as a Cell Broadcast
message, it can be read in PDU format and decoded.  Assuming
channel 50 is being used for this, the composite command to read
it is
 
    AT+CNMI=1,0,2,0,1;+CSCB=0,"50","0-15"
 
The PDU results (unsolicited for each new broadcast) can be
decoded according to GSM 03.38.  Please let me know if you need
further info.

Dear John
 
Thanks for your reply
I am trying to excute it. Thank you.

Thank you
I can now receive cell ID from using AT+CREG=2
then how to send broadcast SMS (PDU) in a specific cell ID so that I can
send to all handsets within the region.
 
for example +CREG: 2,1,"1030","639E"
how to send a broadcast message for LBC no:1030, cellID:693E?

While it's fairly trivial to receive Cell Broadcast (CB)
messages, it's going to be impossible in practice to send them.
Only the network operator can do this, and you're going to need a
huge bank balance to get them to open that door for you.
 
In any case, the (compliant) receiving handsets would need to be
individually configured to receive whatever CB channel your
message content gets assigned.
