If no entry has been made in [Extra Settings] of the modem properties and the dial up
network is started with the phone number
*99#
, no individual PDP context values are
known. In this case the GSM/GPRS modem will use default values for the connection.
The default values are the ones, which had been used for the last connection.
Defining a QoS profile (AT+CGQREQ, AT+CGQMIN)
After the PDP context definition specific optional QoS parameters like delay class or
mean throughput rate can be set before activating the PDP context with the Dial-up net-
work. This can be done via a terminal program (115200 Baud, 8 Databits, No Parity, 1
Stopbit, flow control).:
Start the terminal program. Define the parameters using the “AT+CGQMIN” and/or
“AT+CGQREQ” commands.
AT+CGQREQ=<cid>,<precedence>,<delay>,<reliability>,<peak>,<mean>
<RETURN>
AT+CGQMIN=<cid>,<precedence>,<delay>,<reliability>,<peak>,<mean>
<RETURN>
Example:
AT+CGQREQ=1,3,4,3,0,0 <RETURN>
AT+CGQMIN=1,3,3,3,0,0 <RETURN>
where the numbers correspond to <PDP context identifier>, <Service precedence>, <de-
lay class>, <reliability class>, <peak throughput rate>, <mean throughput rate >.
Close the terminal program when finished to free the communication port.
AT&F and ATZ will be undefined for every context that is inactive or not offline.
The settings are erased when the GSM/GPRS modem’s power is off.
In some cases it may not be required to predefine a PDP context. For example,
if the local network provider does not request an APN. In these cases one of the
two following option can be selected.
NOTE
Select
*99***<cid>#
as the phone number entry in the dial up network, in order to
activate the PDP context with the predefined values. Otherwise, the computer will
ignore the predefined values and activate the PDP context with the default values.
The QoS AT commands can only be used when a PDP context has been defined.
In order to activate the PDP context with the predefined QoS values,
*99***<cid>#
must be selected as the phone number entry. However, if
*99#
is selected, the
computer will ignore the predefined values and activate the PDP context with the
default QoS values.
AT&F and ATZ will be undefined every context which is not active or not online.
The settings are erased when GSM/GPRS modem's power is off.
