1 Scope p. 8

The present document is part of a series of documents that specify charging functionality and charging management in 3GPP networks. The 3GPP core network charging architecture and principles are specified in TS 32.240, which provides an umbrella for other charging management TSs that specify:

the content of the CDRs per domain / subsystem / service (offline charging);
the content of real-time charging messages per domain / subsystem / service (online charging);
the functionality of online and offline charging for those domains / subsystems / services;
the interfaces that are used in the charging framework to transfer the charging information (i.e. CDRs or charging events).

The complete document structure for these TSs is defined in TS 32.240.

The present document specifies the converged offline and online charging description for the Edge Computing domain based on the functional stage 2 description in TS 23.501 and TS 23.558.

Edge computing in 5G environment involves the services or capabilities provided by multiple service providers and entities in the form of following business roles:

ASP providing edge application service to the subscribers;
ECSP providing edge enabling infrastructure and edge enabling services to ASP;
MNO providing 5GS capabilities supporting edge computing.

The present document specifies following charging aspects for Edge Computing:

Subscriber charging:
- MNO charges the subscribers for usage of 5GS capabilities supporting edge computing.
Service-provider charging:
- MNO charges the industry consumer (e.g. ECSP, ASP) for 5GS capabilities provided to support edge computing in total instead of for each individual subscriber;
- ECSP charges the ASP for the edge enabling infrastructure and services.

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.
