Specifies the QOS for traffic patterns in which there is a constant flow of data in one
direction, either upstream or downstream. This traffic pattern should be a higher QOS than the
interactive pattern, but not as high as that for the conversational pattern.

Default: See Usage section for this command
The committed data rate (guaranteed-data-rate) in bps (bits per second).

must be an integer from 1 through 16000000 for the downlink direction or 1 through 8640000 for the
uplink direction. The value must also correspond to one of the permitted values identified in table given in
this chapter. Note that if a non-permitted value is entered for this parameter, then the system rounds the value
to the nearest lower supported value, except in the case where value is less than 1,000 bps. In this case, the
system rounds the value to 1,000 bps. In addition, if the configured committed rate is lower than the value
configured for the peak-data-rate, then the system uses the configured peak rate for this parameter.

Important:
System measurements for this value exclude the GTP and outer packet headers. In addition, some
traffic classes have both a committed rate and a peak rate, while other traffic classes have just a peak rate. If a
committed rate is not applicable (i.e., the traffic class is background or interactive), then an error occurs if this option
is configured. If the committed-rate is applicable (i.e., the traffic class is conversational or streaming), the values
supplied by the SGSN are used if this option is not configured.

Usage
This command configures the APN‘s quality of service (QoS) profile. This feature enables configuring and
enforcing bandwidth limitations on individualPDP contexts of a particular traffic class. Traffic classes are
defined in 3GPP TS 23.107 and are negotiated during PDP context activation. Bandwidth enforcement is
configured and enforced independently on the downlink and the uplink directions.
The profile information is sent to the SGSN(s) in response to GTP Create/Update PDP Context Request
messages. If the QoS profile requested by the SGSN is lower than the configured QoS profile configured, the
profile requested by the SGSN is used. If the QoS profile requested by the SGSN is higher, the configured
rates are used.
Note that the values for the uplink/downlink committed-data-rate and peak-data-rate parameters are
exchanged in the GTP messages between the GGSN and the SGSN. Therefore, the values used may be lower
than the configured values. When negotiating the rate with the SGSN(s), the system convert this to a value
that is permitted by GTP as shown in table given in this chapter.
