For the description of the specific AVP, see the 7750 SR Gx AVPs Reference Guide.
IP-CAN session Usage-Monitoring
A category-map with gx-session-level-usage-monitoring must be associated with the subscriber host or session:
configure
subscriber-mgmt
category-map cat-map-1 create
gx-session-level-usage
PCRF in RAR sends the following AVPs (among all the other mandatory ones: session-id, and so on.)
Usage-Monitoring-Information
Monitoring-Key = ‟any-string”
Granted-Service-Unit
CC-Input-Octets = 1000000
CC-Output-Octets = 1000000
Usage-Monitoring-Level = session_level(0)
Event-Trigger = USAGE_REPORT
The node reports usage when the thresholds are reached some time later in the CCR-U. The usage is monitored internally on the node based on the current sla-profile instance.
Usage-Monitoring-Information
Monitoring-Key = ‟any-string”
Used-Service-Unit
CC-Input-Octets = 1000000
CC-Output-Octets = 1000000
The PCRF instructs the node to continue Usage-Monitoring with the new thresholds in the CCA-U:
Usage-Monitoring-Information
Monitoring-Key = ‟any-string”
Granted-Service-Unit
CC-Input-Octets = 1000000
CC-Output-Octets = 1000000
Usage-Monitoring-Level = session_level(0)
Category Usage-Monitoring
Assume that the following category-map is associated with the subscriber host:
*A:7750>config>subscr-mgmt>cat-map# info
----------------------------------------------
activity-threshold 1
credit-exhaust-threshold 50
category "queue1" create
queue 1 ingress-egress
exit
category "queue3-5" create
queue 3 ingress-egress
queue 5 ingress-egress
exit
category "rest-queues" create
queue 2 egress-only
queue 4 egress-only
queue 6 egress-only
queue 7 egress-only
queue 8 egress-only
exit
The PCRF sends the following AVPs in the RAR message (among all the other mandatory ones: session-id, and so on.)

Charging-Rule-Name = Cat-Map:cat1 — cat-map rule install
Usage-Monitoring-Information
Monitoring-Key = ‟queue-1”

CC-Input-Octets = 2000000
CC-Output-Octets = 2000000

The node reports usage when the thresholds are reached some time later in the CCR-U:
