Introduction
23.2033GPPPolicy and charging control architectureRelease 17TS
Policy and Charging Control functionality encompasses two main functions:
– Flow Based Charging, including charging control and online credit control, for service data flows and application traffic;
– Policy control (e.g. gating control, QoS control, QoS signalling, etc.).
The present document specifies the generic PCC aspects within the body, while the specifics for each type of IP‑CAN are specified in Annexes. For one type of IP‑CAN the corresponding clause in an Annex shall be understood to be a realization of the TS main body. The Annexes are therefore not stand-alone specifications for an IP‑CAN. Annexes may specify additional restrictions to the specification body.
