11.7 AT+CGEQMIN 3G Quality of Service Profile (Minimum
Acceptable)
Description: The test command returns values supported as a compound value.
The read command returns the current settings for each defined context.
The write command allows the TE to specify a Quality of Service Profile for the context
identified by the (local) context identification parameter <cid> which is checked by the MT against
the negotiated profile returned in the Activate/Modify PDP Context Accept message. A special
form of the write command, AT+CGEQMIN=<cid> causes the requested profile for context
number <cid> to become undefined.
AT&F and ATZ will remove the definition of the QoS profiles of every context which is not active
or not online.

Parameters:
<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
<Traffic class>
0 conversational
1 streaming
2 interactive
3 background
4 subscribed value. Default – the default value if the parameter is omitted (40 will be assumed).
<Maximum bitrate UL>
This parameter indicates the maximum number of kbits/s delivered to UMTS (up-link traffic) at a SAP. As an
example a bitrate of 32kbit/s would be specified as 32 (e.g., AT+CGEQMIN=...,32,...).
0 subscribed value. Default – the default value if the parameter is omitted (0 will be assumed).
1...63
64...128 (value needs to be divisible by 8 without remainder)
