The main network elements of the PCC architecture include: a Policy control and Charging Rules Function (PCRF), a Policy and Charging Enforcement Function (PCEF), an Application Function (AF), an Online Charging System/offline Charging System (OCS/OFCS), and a Subscription Profile Repository (SPR). Based on the above architecture, currently, a policy and charging method for performing a visited Access (Visit Access) S9 interface is as follows: and providing access service for the user by a policy control and charging rules function (V-PCRF) of the visited place.
