GPRS network registration status
For GPRS data connections, +CGREG=<n> controls the presentation of an
unsolicited result code, which appears in one of several forms depending on the
value of <n> (or an error if no status is available):
• When <n>=0, no network registration unsolicited result codes are returned.
• +CGREG: <stat> (registration status only) is returned when <n>=1 and
there is a change in the modem's GPRS network registration status.
• +CGREG: <stat>,<lac>,<ci> (which includes location information) is
returned when <n>=2 and there is a change of the network cell.
+CGREG? returns the status of result code presentation and an integer <stat>
showing the current status. (Location information elements <lac> and <ci> are
returned only when <n>=2 and the modem is registered on the network.)
Returned values
The possible returned values of <stat> are:
• 0: not registered, modem is not currently searching a new operator to
register to
• 1: registered
<lac> is a string specifying a two-byte location area code in hexadecimal format
(e.g. “00C3” equals 195 in decimal).
<ci> is a string specifying a two-byte cell ID in hexadecimal format.
