11.11 AT+CGQREQ Quality of Service Profile
(Requested)
Description: The test command returns values supported as a compound value. If the MT supports several
PDP types, the parameter value ranges for each PDP type are returned on a separate line.
The read command returns the current settings for each defined context. If no requested profile
was explicitly specified for a context, simply OK will be returned, but default values will be used
for that context.
This command allows the TE to specify a Quality of Service Profile that is used when the MT
sends an Activate PDP Context Request message to the network.
The set command specifies a profile for the context identified by the (local) context identification
parameter, .
A special form of the set command, +CGQREQ= causes the requested profile for context
number to become undefined.
AT&F and ATZ will undefine the QoS profiles of every context which is not active or not online.
