AVPs

Certain AVPs are applicable in only one direction, while others are applicable to both directions.

AVPs sent by the 7750 SR are used to:

inform the PCRF of the host creation/termination and the subscriber host identity in the 7750 SR
inform the PCRF of the functionality supported in the 7750 SR
report specific events related to the subscriber-host
report the status of the rules
report usage monitoring
report status of the host (existent/non-existent)

AVPs sent by PCRF toward the 7750 SR are used to:

install or activate policies
request usage monitoring
terminate the subscriber-host
request status of the subscriber-host (existent/non-existent)

AVPs that apply to both directions are used for base Diameter functionality such as peering establishment, routing of the Diameter messages, session identification and reporting of catastrophic failures (OSI change).
