Description
This command allows the TE to specify a UMTS 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>.
The specified profile will be stored in the MT and sent to the network only at activation or MS-initiated modification of
the related context. Since this is the same parameter that is used in the +CGDCONT and +CGDSCONT commands, the
+CGEQREQ command is effectively an extension to these commands. The QoS profile consists of a number of
parameters, each of which may be set to a separate value.
A special form of the set command, +CGEQREQ= <cid> causes the requested profile for context number <cid> to
become undefined.
The read command returns the current settings for each defined context.
The test command returns values supported as a compound value. If the MT supports several PDP types, the parameter
value ranges for each PDP type are returned on a separate line.
Defined values
<cid>: a numeric parameter which specifies a particular PDP context definition (see +CGDCONT and
+CGDSCONT commands).
The following parameters are defined in 3GPP TS 23.107 [46] -
<Traffic class>: a numeric parameter that indicates the type of application for which the UMTS bearer
service is optimised.
0 - conversational
1 - streaming
2 - interactive
3 - background
4 - subscribed value
If the Traffic class is specified as conversational or streaming, then the Guaranteed and Maximum bitrate
parameters should also be provided. Other values are reserved.
<Maximum bitrate UL>: a numeric parameter that 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, …). This parameter should be provided if the Traffic class is specified as conversational
or streaming.
<Maximum bitrate DL>: a numeric parameter that 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+CGEQREQ=…,32, …). If the parameter is set to '0' the subscribed value will be requested. This parameter
should be provided if the Traffic class is specified as conversational or streaming.
<Guaranteed bitrate UL>: a numeric parameter that indicates the guaranteed number of kbits/s delivered to
UMTS (up-link traffic) at a SAP (provided that there is data to deliver). As an example a bitrate of 32kbit/s
would be specified as '32' (e.g. AT+CGEQREQ=…,32, …). If the parameter is set to '0' the subscribed value will
be requested. This parameter should be provided if the Traffic class is specified as conversational or streaming.
