Charging implications of IMS architecture
The present document identifies the charging implications of the IMS architecture, which is described in 23.002 [5] and 23.228 [4].
It is expected that the content of this TR will act as a basis for:
- change requests against the architecture specifications [4, 5] of SA2, clarifying the architecture implications on charging;
- change requests against the Charging Principles specification [3] of SA5, which contains the charging architecture and mechanisms;
- detailed specification of Charging Data Description [6] in SA5.
