24.6473GPPAdvice Of Charge (AOC) using IP Multimedia (IM) Core Network (CN) subsystemRelease 16TS

This annex defines the XML Schema to be used for providing the charging information described in annex C in the SIP methods to the served user. As defined in 3GPP TS 32.280 [10], the information elements “special-arrangement”, "special-code" and "billing-id" are not applicable.

The application/vnd.etsi.aoc+xml MIME type used to provide the charging information requested by the served user shall be coded as following described:
