Summary

Recommendation ITU-T Y.2233 specifies the technical requirements and framework which allow for accounting and charging capabilities in NGN. 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. Extensions are also needed in other areas 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 and management aspects of accounting and charging in NGN are out of the scope of this Recommendation.
