At+Cgqreq Quality Of Service Profile (Requested) - Multi-Tech MultiModem EDGE Reference Manual

11.11 AT+CGQREQ Quality of Service Profile (Requested)

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 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, <cid>.
A special form of the set command, +CGQREQ=<cid> causes the requested profile for context
number <cid> to become undefined.
AT&F and ATZ will not define the 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.
1...2
<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>
Delay class
This parameter defines the end-to-end transfer delay incurred in the transmission of SDUs through the GPRS
network(s).
0 Network subscribed value. Default.
1..4 with SDU size = 128 octets and
with SDU size = 1024 octets:
Delay Class
1 (Predictive)
2 (Predictive)
3 (Predictive)
4 (Best Effort)
<reliability>
Reliability class
0 Network subscribed value. Default.
1 Non real-time traffic, error-sensitive application that cannot cope with data loss
2 Non real-time traffic, error-sensitive application that can cope with infrequent data loss
3 Non real-time traffic, error-sensitive application that can cope with data loss, GMM/SM, and SMS
4 Real-time traffic, error-sensitive application that can cope with data loss
5 Real-time traffic, error non-sensitive application that can cope with data loss
