AT+CGQREQ
Quality of Service Profile (Requested)

string parameters whose meanings are specific to the <pdp_type>.
Description:
Allows the TE to specify a Quality-of-Service profile that is used when the MT sends
an active PDP context request message to the network. The set command specifies a
profile for the context identified by the <cid> parameter. Since this is the same
parameter as used in
, AT+CGQREQ is effectively an extension of
AT+CGDCONT. The QoS profile consists of a number of parameters, each which may
be set to a separate value.
A special form of the command, AT+CGQREQ=<cid>, causes the requested profile
for context number <cid> to become undefined.
Set command:
AT+CGQREQ=
[<cid>[,<precedence>[,<delay>[,<reliability>[,<peak>
[,<mean>]]]]]]
Read command:
AT+CGQREQ? Displays the current parameter settings.

Test command:
AT+CGQREQ=? Shows if the command is supported.
Test command
response:
+CGQREQ: <pdp_type>,(list of supported <precedence>s),(list of supported
<delay>s),(list of supported <reliability>s),(list of supported <peak>s),(list of
supported <mean>s)
Parameters:
<cid>:
Integer; specifies the particular PDP context definition. The parameter is local to the
TA-TE interface and is used in other PDP-context related commands. The range of
permitted values (minimum value=’1’) is returned by the test command.
<precedence>:
