scope:

This Recommendation specifies the technical requirements and framework which allow for accounting and charging capabilities in next generation networks (NGNs). It is intended to aid in standardizing protocols and mechanisms to enable accounting and charging for NGN.

In order to support advanced accounting and charging capabilities in NGN, it is important to support policy-based accounting and charging and its associated extensions in terms of requirements, architecture, scenarios and capabilities. Other areas needing extensions are requirements in order to support advanced requirements such as dynamic rating, supporting hierarchy of customer accounts, and online and offline inter-provider settlements. This Recommendation provides such extensions to the previous ITU-T Y.2233 (2008) version.

Non technical aspects of charging in NGN (which are under the responsibility of ITU-T SG 3) and management aspects of accounting and charging in NGN (which are under the responsibility of SG 2) are out of the scope of this Recommendation.
