The 5G Standard

Network Slice charging based on 5G Data Connectivity

Aug 08, 2022

By Gerald Görmer, 3GPP WG SA5 Charging Chair

When Network Slices allocated to third party providers are deployed by Mobile Network Operators, the means by which providers can be charged for usage of assigned Network Slice(s) is not yet described.

The objective of this work item is to provide the functional description of network slice charging based on 5G data connectivity charging performed between the Session Management Function (SMF) and Charging Function (CHF) in the 5GS, as an informative Annex in TS 32.255: ‘Telecommunication management; Charging management; 5G data connectivity domain charging; Stage 2 Details of 5G Data Connectivity charging information for Networks Slice’.

5G Data Connectivity charging specified in 5GS between SMF and CHF for individual UEs PDU sessions from Rel-15, is used with Converged Charging System (CCS) hosting the CHF extended to also cover the third-party provider (addressed under the tenant concept).

By receiving the S-NSSAI for each UE PDU session, the enhanced CCS is able to perform per tenant charging based on tenant's Network Slice total UEs data connectivity usage, the Network Slice being identified by the S-NSSAI.

The internal behaviour of the enhanced CCS is not specified in this release.
