226 GPRS commands 6615-2220
+CGCLASS – GPRS mobile station class
Description:
The set command is used to set the MT to operate according to the specified GPRS
mobile class. If the requested class is not supported, an ERROR or +CME ERROR
response is returned.
The read command returns the current GPRS mobile class.
The test command is used for requesting information on the supported GPRS mobile
classes.
Syntax:
AT+CGCLASS= [<class>]
Response Syntax:
AT+CGCLASS?
+CGCLASS: <class>
AT+CGCLASS=?
+CGCLASS: (list of supported <class>s)
Parameters:
<class>
A string parameter which indicates the GPRS mobile class (in descending order of func-
tionality)
“A”: class A (highest)
“B”: class B
“CG”: class C in GPRS only mode
“CC”: class C in circuit switched only mode (lowest)
Other values are reserved and will result in an ERROR response to the set command.
If the MT is GPRS attached when the set command is issued with a <class> = CC speci-
fied, a GPRS detach request is sent to the network.
If the MT is GSM attached when the set command is issued with a <class> = CG speci-
fied, a GSM detach request is sent to the network.
Class A is not supported by the GDW-xx modems.
NOTE:
During switch-On in CG class, the MS always performs an automatic GPRS attach (the
ATTACH-STATUS parameter of +WGPRS is ignored).
But if the MS is not already GPRS attached when switching from B/CC class to CG class
then no automatic GPRS attach is performed.
