CGF

Enabling Accurate, Scalable Offline Charging for 3G, 4G, and 5G Networks

As telecom networks handle increasing volumes of usage data across 3G, 4G, and 5G, operators must efficiently capture, process, and bill postpaid and offline charging models. The Charging Gateway Function (CGF) is a critical component of offline charging, ensuring accurate collection, formatting, and forwarding of Call Detail Records (CDRs) and Event Detail Records (EDRs) to the Offline Charging System (OFCS).

CGF is key for batch-based billing and usage tracking, ensuring that usage data from diverse services—such as voice, data, and messaging—is efficiently processed for accurate postpaid invoicing. Without a reliable CGF, CSPs risk billing delays, incomplete usage records, and revenue leakage—issues that can lead to financial losses and customer dissatisfaction. The rise of 5G, IoT, and network slicing further amplifies this complexity, introducing differentiated service tiers, ultra-low latency applications, and diverse Quality of Service (QoS) parameters that require precise billing models.

DigitalRoute’s CGF guarantees that all usage data is accurately processed, formatted, and delivered for billing, enabling CSPs to prevent revenue leakage, support advanced charging models, and maximize postpaid revenue streams.

Addressing the Challenges of Offline Charging 

CSPs must handle large-scale, diverse usage records across multiple networks and charging models, requiring real-time accuracy, efficiency, and seamless integration with billing systems. 

Key challenges include: 

  • Accurate Postpaid & Deferred Charging Data Processing – Offline charging requires precise CDR and EDR collection, ensuring all usage data is formatted correctly for post-usage billing. 
  • Preventing Revenue Leakage & Billing Delays – Without a robust CGF, CSPs risk losing revenue due to missing or improperly processed usage records. 
  • Handling 5G Network Slicing & Complex Billing Models – Each network slice may have distinct service attributes (latency, bandwidth, priority), requiring CGF to aggregate and format usage data accordingly for accurate, differentiated billing. 
  • Scaling for High-Volume Data in 5G & IoT Environments – The exponential growth of real-time IoT monitoring, high-bandwidth services, and ultra-low latency applications demands an optimized CGF that can efficiently process massive amounts of usage data. 

Without an advanced CGF, CSPs face billing inefficiencies, operational complexity, and reduced revenue recognition. 

DigitalRoute’s CGF eliminates these challenges by delivering an intelligent, automated offline charging solution tailored for modern telecom networks.
