11.8 AT+CGEQREQ 3G Quality of Service Profile
(Requested)
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 used when the MT sends
an Activate PDP Context Request message to the network.
A special form of the write command, AT+CGEQREQ=<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.

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 (4 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+CGEQREQ=...,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)
