As part of the agreement of moving common IMS work from ETSI TISPAN to 3GPP, there is a need to ensure that the work on simulation services that are still not frozen within TISPAN is continued within 3GPP. Within TISPAN the WI 3027 (TS183015) on the description for CW like service is still within the draft status.

This work creates Stage 3 for CW-like service in 3GPP IMS. New capabilities are in line with RFC3427. Interoperability between networks was taken into consideration. Interworking was specified.

AoC service is standardized in 3GPP and available for CS and PS networks based on Charge Advice Information (CAI). TISPAN introduced AoC based on Tariff Information according to ITU Recommendations and ETSI specifications. AoC service is becoming available in 3G IMS networks, hence the usage of AoC should be defined in 3GPP.

AoC is currently listed in the 3GPP charging requirements TS 22.115. High level description on AoC Information and Charging levels is specified in TS 22.086 and TS 23.086. AoC is based on the Charge Advise Information (CAI) defined in TS 22.024. Support of subscribed AoC in CAMEL for CS and PS networks is specified in TS 23.078. Requirement for AoC support in TISPAN is handled in WID02037 and considers the SIP transfer of charging information in WID 3113.

The transport of tariff information, the evaluation and the advice to the mobile subscriber is not described in IMS.

This work introduces AoC in 3GPP IMS Charging and is limited to support AoC information on the corresponding charging interfaces as well as in the OCS (Online Charging System).

A new TS 32.280 contains definitions for AoC and description of AoC in IMS Charging. It contains the AoC Information for charging purposes. The determination for SIP transport of tariff information followed the requirements in TS 22.273. The mechanism for tariff change and support of the tariff format adhered on the existing 3GPP principles. Additions, e.g. for different use case or simplifications is For Further Study.

AoC service provision and information transfer is made available as a SIP-based IMS service. Transfer of tariff information is outside the scope of this WID but is For Further Study in other 3GPP groups.

The presentation of the AoC information at the UE/ME is outside the scope of this WID but is For Further Study in other 3GPP groups.
