This TR intends to study the impact of the evolved 3GPP system architecture with respect to charging.
The study covers the relevant non-roaming and roaming use cases for both 3GPP and non-3GPP accesses specified in TS 23.401
and TS 23.402
The study aims at producing recommendations for the following aspects:
3GPP work item and specification structure;
charging requirements and principles;
charging architecture and charging scenarios; and
charging data and protocols.
The aspect of charging requirements and principles includes the study of the reuse of 3GPP Release 7 charging specifications.
