AA subscriber state

AA subscriber state must exist for App-profiles and ASO overrides to be applied.

The app-profile for the aa-sub is applied explicitly by a CCR-I or RAR message with an AVP AA-App-Profile-Name.

App-profiles interact with ASO characteristics in this way:

• The AA-App-Service-Options AVP within the app-profile assignment is optional at subscriber instantiation time and may be used later to modify the policy.

• The newly submitted AA-App-Profile-Name AVP overwrites the one that is already applied. Any ASO AVPs that is received within the Gx message is applied.

  Note: If an app-prof AVP is present, even if it is the same app-profile as currently applied, all previous ASO override policies are removed for the sub.

The state of the subscriber policy attributes is modified by ASO AVPs in this way:

• The app profile can define one or more ASO characteristics attributed to a subscriber.

• If there are multiple ASO AVPs for the same characteristic in the message, the first one takes effect.

• There is no explicit delete of ASO overrides (the PCRF can always resend or change the app-profile to delete all overrides).
