Charging 6G: AI tokens and multi-dimensional resources

SA5’s 6G charging study (TR 32.801-02) is at v0.6.0. Its new questions are how to charge for resources other than bytes, including AI tokens, computing, sensing and agents, and whether charging should be centralised or distributed.

In 60 seconds

  • Three topics: architecture, mechanism, and charging for 6G services.
  • Architecture options: distributed vs centralised local charging systems, and a 6G converged charging architecture.
  • New metrics: AI tokens, computing, ISAC, AI agents and training services, plus intent-based charging.
  • 26 solutions under the charging-mechanism topic alone.

Architecture: where the charging system sits

Key issueQuestion
#1.1Charging for edge applications
#1.2The 6G charging architecture itself
#1.3Adjusting charges for UE contributions
#1.4Interworking across 6G, 5G and EPS

Five solutions compete:

  • #1.1: distributed architecture with local charging systems
  • #1.2: centralised architecture with local charging systems
  • #1.3: a 6G converged charging architecture
  • #1.4: UE adjustment mechanisms
  • #1.5: verification-based adjustment

Mechanism and the new metrics

The mechanism topic (#2.1–#2.9) covers data interoperability while 5G and 6G coexist, how the charging APIs and ASN.1 are organised, multi-dimensional resource charging, optimisation and reliability. It carries 26 solutions, including unified data handling, compression, dynamic switching, and charging based on performance measurements.

The service topic is where 6G differs from 5G. Key issues cover AI traffic, media components, intent-based charging, AI token metrics, dynamic QoS, ISAC, system data exposure, AI agents, training services and computing services. Each needs a unit and a trigger that the 5G converged charging system does not have.

SAFS_6G_CH

Owners and status

Rapporteur: Zhiwei Mo (China Telecom). Work item FS_6G_CH, WID SP-251708, September 2025 to June 2027. It started earliest of the SA5 6G studies.

Still open

Distributed vs centralised architecture, and which units become normative for AI tokens and computing. The report’s direction is to evolve 5G converged charging, not replace it.

Watch next

  • SA5#169, Prague (12–16 Oct): whether the architecture options narrow.
  • SA1 requirements: charging requirements for AI services in TS 22.270, due for approval in December.
