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 undefine 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.

4 subscribed value. Default
<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.
1...63
64...128 (value needs to be divisible by 8 without remainder)
256
512
<Maximum bitrate DL>
This parameter indicates the maximum number of kbits/s delivered by UMTS (down-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.
1...63
