2.5.3.4 Quick Network Status Checking
Once the mobile has registered on one network, it may be useful to know the received signal strength
and the network on which the mobile is registered. These information can be gathered with the
commands +CREG, +COPS and +CSQ, which are part of the standard ETSI GSM 07.07 commands
as seen before, unfortunately these commands are not so fast in the response due to network
response time, especially the +COPS command. If You want to keep your software as general as
possible you can follow the indications given before and forget this part; instead if you need or want a
faster way to check at the mobile network information, the GM862-GPS provides a special command
#MONI which can be used to gather all the information needed in a faster and simpler way:
•
send command
AT#MONI=0<cr>
•
wait for OK response
•
send command
AT#MONI?<cr>
•
wait for response in the format:
#MONI: <netname> BSIC:<bsic> RxQual:<qual> LAC:<lac> Id:<id> ARFCN:<arfcn>
PWR:<dBm> dBmTA: <timadv>
OK
or in the case the network name is not known:
#MONI: Cc:<cc> Nc:<nc> BSIC:<bsic> RxQual:<qual> LAC:<lac> Id:<id> ARFCN:<arfcn>
PWR:<dBm> dBm TA: <timadv>
OK
where:
<netname> = name of network operator
<cc> = country code
<nc> = network operator code
<n> = progressive number of adjacent cell
<bsic> = base station identification code
<qual> = quality of reception (0-7) (same as <ber> of +CSQ command)
<lac> = localization area code
<id> = cell identifier
<arfcn> = assigned radio frequency channel
<dBm> = received signal strength in dBm (same as "decoded" rssi value)
<timadv> = timing advance
