1 Scope p. 7

The present document studies the charging aspects to better support vertical scenarios, which is different with the existing customer charging baseline, specified in TS 32.240, and makes the evolution of charging specifications clearer, which focuses on studying the charging principles and references of verticals charging, and aims to provides an guideline for other charging management TSs that specify the verticals charging.

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.

4.1 General p. 9

For 5GS, there are several charging specifications focus on the charging aspects about wholesale and business to business for Industry verticals. Corresponding charging specifications needs to be studied on how it could be documented, including but not limited to the charging aspect of Network Slice, Non-Public Network, Time Sensitive Network, Edge Computing, and 5G LAN etc. The charging architecture and principles of vertical scenarios are different from those of subscriber charging scenarios which specified in the TS 32.240.

4.2 Charging specifications reference considerations p. 9

A set of charging specific TSs covers the 5GS domains and 5G service levels (e.g. Network slice, 5G LAN and TSN, etc.) respectively, in the TS 32.2xx and TS 28.2xx TS number ranges. These TSs describe the mapping of the common charging architecture, charging requirements and charging principles onto the specific services, scenarios, for converged online and offline charging. They are commonly referred to as the middle tier charging TSs.

The following charging technical specifications reference for vertical charging are:

NEF Charging is specified in the TS 32.254.
5G LAN Charging is specified in the TS 32.254.
Edge Computing is specified in the TS 32.257.
Network Slicing is specified in the TS 28.201, TS 28.202 and TS 28.203.
Data connectivity charging is specified in the TS 32.255.

The following charging technical report reference for vertical charging are:

NPN Charging is studied in the TR 28.828.
TSN Charging is studied in the TR 28.839.
Network slice charging is studied in the TR 32.847.
Wholesale charging is studied in the TR 28.827.

A set of TSs in the TS 32.29x range covers common aspects, such as CDR parameter and syntax descriptions, online and offline charging applications, and the charging interactions within the network (CDR transfer) as well as between the network and the Billing Domain (CDR file transfer).

4.3 The concept clarification p. 9

The vertical domain is an industry or group of enterprises in which similar products or services are developed, produced, and provided, specified in the TS 22.104. For example, the typical vertical domains can be the factories of the future; electric-power distribution and central power generation; and connected hospitals or medical facilities.

The enterprise is an organization, a company, or a business. For example, the typical enterprises can be the manufacturing/catering/farming enterprise, a large/small/medium-sized enterprise.

The Tenant in 3GPP management system is a group of 3GPP management system users associated with the management capabilities they are allowed to access and consume, described in clause 4.8 of TS 28.533. The tenant in charging aspect can be the network slice subscriber, i.e. the party for which the network slice instance(s) is(are) created, satisfying the requirements of subscribed-to service(s), specified in the TS 28.202.

The Subscriber is used to identify the enterprise based on the subscription relationship between enterprise and MNO, for example, which can be the Tenant id for the network slice charging.
