Content charging is performed by the Active Charging Service (ACS) only after the request has been controlled by the
application server. This guarantees the appropriate interworking between the external application and content-based
billing. In particular, this guarantees that charging will be applied to the appropriate request in case of redirection, and
that potential charging-based redirections (i.e. Advice of Charge, Top Up page, etc.) will not interfere with the decisions
taken by the application server.

Determining the appropriate action (permit, deny, redirect) to take for the type of content based on subscriber
profile
Communication of the action (permit, deny, or redirect) decision for the URL back to the ACS module
