The present document is part of a series of documents that specify charging aspects of network slicing. The present document includes the charging aspects of network slice performance and analytics, including charging scenarios, data and way of data transfer specific for the network slice. The architecture for network slice charging follows common architecture and concepts specified in TS 32.240. The charging aspect of network slice charging on PDU session charging is specified in TS 32.255. The network slice performance and analytics charging collects and processes charging information related to performance metrics of a network slice. All references, abbreviations, definitions, descriptions, principles and requirements, used in the present document, that are common across 3GPP TSs, are defined in TR 21.905. Charging management in 3GPP networks/domains, services or subsystems are provided in the umbrella TS 32.240 and are 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.

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.
