HUAWEI MG323 GSM M2M Module
AT Command Interface Specification	Commands for Network Services

8.3.4+CREG – Command for Unsolicitedly Reporting the Network Registration Status

URC	z If AT+CREG is set to 1, when the network registration status is
	changed:
	<CR><LF>+CREG:<stat><CR><LF>
	z If AT+CREG is set to 2, when the network registration status or
	network cell is changed:
	z <CR><LF>+CREG:<stat>[,<lac>,<ci>]<CR><LF>
Function	Indicates that the network registration status is changed.

8.3.5 Examples

Example 1:

Query the current status of network registration.

AT+CREG?

+CREG: 0,1Has been registered with the local network and does not unsolicitedly report the CREG information.

Example 2:

Set unsolicited reporting of the current +CREG information.

AT+CREG=2

8.4 AT+CSQ - Command for Querying the Signal Quality

The AT+CSQ command queries the signal quality and returns the receive signal strength indicator <rssi> and channel bit error rate <ber> that are sent by the ME.
