CHF

CSPs require flexible, real-time charging solutions to support evolving business models. The Charging Function (CHF) is a core component of the 5G Converged Charging System (CCS), responsible for real-time event-based charging, dynamic policy application, and seamless prepaid/postpaid billing across multiple service types, including voice, data, and messaging.

CSPs’ key 5G charging challenges

01

Real-Time Charging Across 5G Services

5G SA requires timely event- and session-based charging interactions across services and differentiated service attributes.

02

High-Scale Charging Event Processing

The CHF must handle high volumes of charging requests and usage information from multiple 5G network functions and service domains with the performance required for online charging.

03

Evolving Charging Models

Network slicing, differentiated QoS and other 5G capabilities introduce new charging attributes and commercial models that charging systems must be able to identify and monetize.

04

Coexistence with Existing Charging Systems

CSPs need to introduce 5G SA charging while preserving existing OCS, rating, balance management, and billing investments, requiring standards-based interoperability and a practical migration path.

Without a scalable, standards-based CHF, CSPs risk inaccurate charging, revenue leakage, and greater complexity connecting 5G SA services to existing charging and billing environments.

How We Help CSPs Manage 5G charging

5G SA Charging Interoperability

Bridge the 5G SA Core and charging domain with a standards-based CHF layer, so CSPs can introduce 5G charging while preserving existing rating, billing, and revenue systems.

Event & Session-Based Charging

Support converged online and offline charging flows, including session-based and event-based charging interactions.

Extend Existing Charging Investments

Integrate with existing Rating Function and Account Balance Management capabilities to introduce 5G SA charging without replacing the existing OCS.

Flexible Charging Traffic Routing

Route charging traffic across OCS, CCS, billing, and partner systems using configurable rules based on network, service, slice, customer, or business context.
