Telecommunication management; Study on charging management; 3GPP Evolved Packet Core (EPC): Charging aspects
The present document 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 [3] and TS 23.402 [4].
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.
