This command defines a condition based on the threshold conditions in
usage of traffic by subscriber session in an IP-CAN session. It is used to
support usage tracking and dynamic Policy control based on subscriber usage.

Syntax
[ no ] threshold-condition usage-monitor usage_mon_name { time | vol-or-time | volume } usage operator { absolute value volume | subscription-limit | subscription-threshold subs_thres_limit}
no
Removes the specified condition definition.
usage_mon_name
Specifies a unique name for configured usage monitor condition which
is used for evaluation with this condition group for user traffic in IP-CAN
session.
usage_mon_name must be an alphanumeric
string of 1 through 63 characters.
usage
This keyword specifies the condition as usage for threshold condition
which is used for evaluation with this condition group for user traffic in
IP-CAN session.
operator
Specifies how to logically match the information in the analyzed
field.
operator must be one of the following:
{time | vol-or-time | volume }
This keywords sets the type of thresold; time or volume or both as
condition definition for user traffic in IP-CAN session.
- time : This keyword sets the threshold
condition to use time as condition definition for a user traffic in IP-CAN
session.
- vol-or-time : This keyword sets the
threshold condition to use time or volume as condition definition for a user
traffic in IP-CAN session. The condition is matched if either of the two usage
values fulfills the condition.
- volume : This keyword sets the threshold
condition to use volume as condition definition for a user traffic in IP-CAN
session.
absolute value
volume
Specifies the threshold limit condition definition based on absolute
usage volume
volume in Kilo Bytes which is used for
evaluation with this condition group for user traffic in IP-CAN session.
volume must be an integer between 1 through
4294967295.
subscription-limit
Specifies the threshold limit condition based on Subscriber's
subscription limit which is used for evaluation with this condition group for
user traffic in IP-CAN session.
In this condition the system takes Subscriber's subscription limit as
defined in subscriber subscription policy for threshold limit monitoring.
subscription-threshold
subs_thres_limit
Specifies the condition definition for threshold limit based on a
configured usage monitor threshold named
subs_thres_limit in IP-CAN session.
subs_thres_limit is a pre-configured
subscription limit in this configuration mode.
This command allows the operator to use configured subscription limit
as subset of a threshold condition.
Usage Guidelines
Use this command to define a condition based on the duration of usage
of service in seconds or volume usage in Bytes for user traffic in an IP-CAN
session. This usage monitor is used to support usage tracking and dynamic
Policy control based on subscriber usage.
IPCF supports the concept of Monitoring Key. PCEF, when instructed by
PCRF, keeps track of usage per Monitoring Key. PCEF reports the usage when
thresholds are reached or requested by PCRF.
To allow operator to have dynamic Policy control, IPCF uses Usage
Monitor. This Usage Monitor has attribute of volume-limit, time-limit or
both. Operator can "associate" different Monitoring Keys to these usage
monitors. It can be a Many-To-Many relationship between Usage-Monitor and
Monitoring-Key. Operator can use Usage conditions on Usage Monitors instead of
Monitoring Keys directly.
IPCF tracks usage per usage-monitor. Different monitoring keys
associated to a Usage-Monitor. When monitoring key is associated to a
Usage-Monitor, the usage reported for that particular monitoring key is added
to all the usage monitoring to which it is associated.
IPCF supports 2 types of usage monitors; it can be defined on IPCF or
SSC supplied usage monitors. The name
usage_mon_name identifies an usage-monitor,
which is locally defined or received from SSC. The
absolute value applies to both types of usage
monitors.
This command allows the operator to use configured threshold condition
with another threshold condition as subset.
A maximum of 8 thresholds can be configured per usage monitor.
Example
The following command creates a threshold condition with usage monitor
name
threshold1 as usage monitor to trigger the
condition based on the
subscription limit as provide in Subscriber
policy:
threshold-condition usage-monitor threshold1 usage = subscription-limit
