Excerpt from TS 23.503
1 Scope
The present document defines the Stage 2 policy and charging control framework for the 5G System specified in TS 23.501 [2] and TS 23.502 [3].
The policy and charging control framework encompasses the following high level functions:
- Flow Based Charging for network usage, including charging control and online credit control, for service data flows;
- Policy control for session management and service data flows (e.g. gating control, QoS control, etc.);
- Management for access and mobility related policies;
- Management of UE policy information.
Interworking with E-UTRAN connected to EPC is described in TS 23.501 [2].
TS 23.502 [3] contains the stage 2 procedures and flows for the policy and charging control framework and it is a companion specification to this specification.
TS 32.255 [21] contains the functional description of the converged offline and online charging functionality for the 5G System.
