Configuration Overview

QoS-group-of-ruledefs are statically configured in the CLI, in the Active Charging Service Configuration Mode. The
CLI allows addition and removal of charging and dynamic ruledefs to a named QoS-group-of-ruledefs. A single ruledef
can belong to multiple QoS-groups. A maximum of 64 QoS-group-of-ruledefs can be configured in the ACS service.
Each QoS-group-of-ruledefs can contain up to 128 ruledefs.
PCRF will be aware of all QoS-group-of-ruledefs names and their constituent ruledefs configured on the chassis/PCEF.
The PCRF can activate and remove QoS-group-of-ruledefs for a subscriber session over Gx using a proprietary AVP in
CCA and RAR messages. This AVP specifies the name of the QoS-group-of-ruledefs to activate or to remove.
Individual ruledefs cannot be dynamically added or removed from a predefined QoS-group-of-ruledefs over the Gx
interface. Attributes of QoS-group-of-ruledefs (FUP-QoS parameters) cannot be defined in the CLI. These parameters
can only be set and changed over the Gx interface. This feature allows setting different QoS parameters for different
subscribers for a named QoS-group-of-ruledefs.
The following attributes of QoS-group-of-ruledefs are supported:
 Precedence or Priority: Priority of a QoS-group-of-ruledefs implies priority of applying QoS-parameters of a
QoS-group-of-ruledefs to an incoming data packet. If a packet matches a charging rule which is part of
multiple QoS-groups activated for the session, then QoS-parameters of the QoS-group-of-ruledefs with highest
priority is applied to the packet. A lower priority number indicates higher priority of application of QoS-
parameters of that group. Priority of a QoS-group-of-ruledefs is set by PCRF over Gx for each subscriber
session.
 Flow-Status: Can be set to Forward, Block, or Redirect.
 Flow-Rate: Specifies max rate, max burst-size, conform action, and exceed action; individually for uplink and
downlink traffic.
 Usage Monitoring Key: A monitoring key, which has an integer value, is set by PCRF over Gx. Volume
threshold values are set for this key by PCRF, to perform usage monitoring. Usage is tracked against a
monitoring key.
 Volume Thresholds: The PCRF can set volume threshold values for a monitoring key over Gx. An event is
reported when thresholds are crossed, and usage is reported at predefined events — such as session termination
and when the QoS-group-of-ruledefs removed is the last using the shared volume-quota.
 Attributes of QoS-group-of-ruledefs cannot be defined using CLI. These attributes can only be set and changed
over Gx. This allows setting different QoS parameters for different subscribers for a named QoS-group-of-
ruledefs.
 When a QoS-group-of-ruledefs is activated, its QoS parameters can be set and changed over Gx. This is achieved
using a combination of standard and proprietary AVPs.
 The following attributes of charging-action can be set and changed by PCRF over Gx.
 Flow-Status: Can be set to Forward, Block, or Redirect.
