The present document specifies the Advice of Charge (AoC) framework for relevant events, sessions, and services. The 3GPP umbrella charging architecture and principles are defined in TS 32.240.
The AoC framework detailed herein provides for both offline and online charging models. It specifies the following:
- The AoC architecture.
- The common principles that govern AoC.
- The AoC function that enables the IMS AoC framework.
- Exemplary message flows.
- AoC interface data description.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

3 Definitions, symbols and abbreviations p. 8
3.1 Definitions p. 8
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Add-on charge:
additional charge on top of the current tariff. An add-on charge can either be metered in non-monetary units (e.g. meter pulse) or in monetary-units (e.g. currency).
Advice of Charge (AoC):
The Advice of Charge (AoC) supplementary service provides AoC Information to the served user for information (AoCI) or for charging (AoCC) related to a corresponding event, session or usage of a service. The AoC service may be delivered prior to, during or after the service delivery.
AoC for Information (AoCI):
An AoC supplementary service where the provided information is non-binding. I.e. the provided information is an estimation of the service cost and/or tariff. The provided information and the actual charges may differ.
AoC for Charging (AoCC):
An AoC supplementary service where the provided information is binding. I.e. the provided information shall correspond to the actual charges.
AoC at communication set-up time (AOC-S):
An AoC supplementary service provided at communication establishment and/or at tariff switch time. The provided information includes Tariff Information for the requested service.
AoC during the communication (AOC-D):
An AoC supplementary service provided during the communication at predefined triggering conditions. The provided information includes accumulated Cost for the ongoing usage.
AoC at the end of communication (AOC-E):
An AoC supplementary service provided when the communication is released. The provided information includes the total accumulated Cost.
Auxiliary Advice of Charge Function (AACF):
An AACF provides Tariff and/or Cost information for the requested service. The AACF resides outside of the local AoC function and the charging domain.
Charge Advice information (CAI):
CAI elements as described in TS 22.024.
Charge Determination Point (CDP):
Defined in ETSI ES 201.296 [214].
IMS-based PSTN/ISDN Emulation Sub-system (PES):
Defined in ETSI TS 182 012 [212].
Tariff:
set of parameters defining the applied charges for the use of a particular bearer / session / service.
