The present document specifies the AoC framework for relevant events@ sessions@ and services. The 3GPP umbrella charging architecture and principles are defined in 3GPP TS 32.240 [1]. 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. All terms@ definitions and abbreviations used in the present document@ that are common across 3GPP TSs@ are defined in the 3GPP Vocabulary@ TR 21.905 [100]. Those that are common across charging management in 3GPP network@ services or subsystems are provided in the umbrella document TS 32.240 [1] and may be copied into clause 3 of the present document for ease of reading. Finally@ those items that are specific to the present document are defined exclusively in the present document. Requirements that govern the AoC work are specified in 3GPP TS 22.115 [101].
