At+Cgqmin Quality Of Service Profile (Minimum Acceptable) - Multi-Tech MultiModem EDGE Reference Manual

11.10 AT+CGQMIN Quality of Service Profile (Minimum
Acceptable)
The test command returns values supported as a compound value. If the MT supports several
Description:
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.
This command allows the TE to specify a minimum acceptable profile which is checked by the
MT 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>.
A special form of the set command, AT+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.
AT&F and ATZ will not define the minimum QoS profiles of every context which is not active or
not online.

Parameter Descriptions:
<cid>
Parameter specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is
used in other PDP context-related commands.

<precedence>
Precedence class
0 Network subscribed value. Default.
1 High Priority. Service commitments shall be maintained ahead of precedence classes 2 and 3
2 Normal priority. Service commitments shall be maintained ahead of precedence class 3
3 Low priority. Service commitments shall be maintained
<delay>(num)
Delay class
The delay parameter defines the end-to-end transfer delay incurred in the transmission of SDUs through the
GPRS network(s).
0 Network subscribed value. Default.
