Quality of Service Profile Minimum Acceptable
+CGQMIN
Multi-Tech Systems, Inc. GPRS AT Commands Reference Guide (Document Number S000293J)
Description:
Values:
Syntax:
This command allows the DTE to specify a minimum acceptable profile which is checked by the modem
against the negotiated profile returned in the Activate PDP Context Accept message.
The set command specifies a profile for the context identified by the local context identification
parameter, <cid>. Since this is the same parameter that is used in the +CGDCONT command, the
+CGQMIN command is effectively an extension to the +CGDCONT command. The QoS profile consists
of a number of parameters, each of which may be set to a separate value.
A special form of the set command, +CGQMIN= <cid> causes the minimum acceptable profile for
context number <cid> to become undefined. In this case no check is made against the negotiated
profile.
The read command returns the current settings1 for each defined context.
The test command returns values supported as a compound value. If the modem supports several PDP
types, the parameter value ranges for each PDP type are returned on a separate line.
<cid>: a numeric parameter which specifies a particular PDP context .
<precedence>: a numeric parameter which specifies the precedence class.
<delay>: a numeric parameter which specifies the delay class.
<reliability>: a numeric parameter which specifies the reliability class.
<peak>: a numeric parameter which specifies the peak throughput class.
<mean>: a numeric parameter which specifies the mean throughput class.
