Converged Charging System Connects to IPLOOK 5GC
- The Charging Function (CHF) receives Nchf interface messages sent from the SMF and handles the routing and forwarding of these messages.
- The Charging Data Function (CDF) collects billing messages, generates corresponding Charging Data Records (CDRs), and sends them to the Charging Gateway Function (CGF), which processes the CDRs and generates billing files for the BOSS to collect through the file interface. Meanwhile, the CHF supports forwarding billing request messages sent by the SMF to the BOSS and relays the BOSS responses back to the SMF.

FAQ
What is the Charging Function (CHF) in a 5G network?
The Charging Function (CHF) is a core component of the 5G Service-Based Architecture (SBA) responsible for real-time charging, billing, and monetization of telecom services. It manages charging interactions between network functions such as the SMF and external billing systems, enabling operators to support flexible charging models for 5G services.
What is the difference between CHF, CDF, and CGF?
The CHF handles real-time charging communication and policy coordination with network functions. The Charging Data Function (CDF) collects charging information and generates Charging Data Records (CDRs). The Charging Gateway Function (CGF) processes these CDRs and generates billing files for integration with BOSS/BSS systems.
Which services can IPLOOK’s charging platform support?
The platform supports charging for voice, video, SMS, mobile data, VAS, IPTV, IoT/M2M services, SDN/NFV environments, and advanced 5G services such as network slicing and Industry 4.0 applications.
Does the solution support both online and offline charging?
Yes. IPLOOK’s Converged Charging System (CCS) supports online charging, offline charging, and converged charging models. This enables operators to provide prepaid, postpaid, and hybrid billing services within a unified charging platform.
How does the CHF integrate with the 5G Core Network?
The CHF connects to the 5G Core through the standardized Nchf interface. It receives charging requests from the SMF, routes charging messages, communicates with external billing systems such as BOSS/OCS platforms, and returns charging responses back to network functions.
What scalability and reliability features are included?
The platform supports dynamic routing through NRF discovery, quota management during BOSS failures, scalable capacity provisioning, and fault-handling mechanisms with corresponding response codes. These features ensure reliable charging operations in high-volume telecom environments.
Can the charging platform integrate with third-party systems?
Yes. The solution provides standardized APIs and flexible integration capabilities for BOSS, OCS, CRM, and third-party business systems. This enables operators to integrate billing, customer management, and service monetization into existing operational ecosystems.
What business benefits does the CHF provide to operators?
IPLOOK’s CHF helps operators accelerate monetization of 5G services, improve billing accuracy, support flexible pricing models, simplify customer provisioning, and reduce operational complexity. It also enables telecom providers to launch new revenue-generating services more quickly across consumer, enterprise, and IoT markets.
