5.3.1 Re-authorization
The server may specify an idle timeout associated with a granted quota. Alternatively, the client may have a configurable default value. The expiry of that timer shall trigger a re-authorization request.
Mid-session service events (re-authorization triggers) may affect the rating of the current service usage.
The server may instruct the Credit-Control client to re-authorize the quota upon a number of different session related triggers that can affect the rating conditions.
When a re-authorization is trigger, the client shall reports quota usage. The reason for the quota being reported shall be notified to the server.
5.3.2 Threshold based re-authorization triggers
The server may optionally include an indication to the client of the remaining quota threshold that shall trigger a quota re-authorization.
5.3.3 Termination action
The server may specify to the client the behaviour on consumption of the final granted units, or zero units granted in the first place; this is known as termination action.
5.3.4 Account expiration
The server may provide to the client the date and time of account expiration, which the client may use depending on operator policy.
