AT+CGQMIN
Quality of Service Profile (Minimum Acceptable)
Description:
Allows the TE to specify a minimum acceptable profile which is checked by the MT
against the negotiated profile returned in the Active PDP Context Accept Message.
The set command specifies a profile for the context identified by the <cid> parameter.
Since this is the same parameter as used in AT+CGDCONT, AT+CGQMIN 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+CGQMIN=<cid>, causes the minimum accepted
profile for context number <cid> to become undefined.
Set command:
AT+CGQMIN=
[<cid>[,<precedence>[,<delay>[,<reliability>[,<peak>
[,<mean>]]]]]]
Read command:
AT+CGQMIN? Displays the current parameter settings.

Test command:
AT+CGQMIN=? Shows if the command is supported.
Test command
response:
+CGQMIN: <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.
