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:

– 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.
