  • PPS and Prepaid Client are two important functional entities that implement online charging. The two cooperate to complete online charging for users: PPS first converts the real-time user account balance into a certain number of quotas. (The quota refers to the data traffic that the user can use or the duration of the call that the user can use, etc.), and then allocates some of the above quotas to the terminal, and notifies the part of the quota to the PPC; the PPC is responsible for obtaining the data.

This is repeated until PPS finds that all quotas have been used up (ie, the real-time user account balance is insufficient).
