OFCS

As telecom operators deliver postpaid services across voice, data, SMS, and roaming, they require a reliable offline charging system to ensure accurate billing, prevent revenue leakage, and maintain financial integrity. The Offline Charging System (OFCS) processes Call Detail Records (CDRs) and Event Detail Records (EDRs) from network services and forwards them to the billing system for postpaid invoicing. Unlike real-time charging, OFCS enables charging to be handled after service consumption, making it essential for batch-based processing and postpaid billing models.

Without an advanced OFCS, CSPs risk billing delays, missing usage records, and inaccurate postpaid invoices, leading to financial discrepancies and dissatisfied customers.

DigitalRoute’s OFCS guarantees that all usage events—voice, data, SMS, international roaming, and premium services—are accurately processed, formatted, and delivered for billing. By automating batch-based processing, DigitalRoute’s OFCS helps CSPs prevent revenue leakage, optimize billing accuracy, and ensure seamless postpaid monetization across all services.

Addressing the Challenges of Offline Charging 

Managing postpaid billing and offline charging across multiple services and customer segments requires a highly efficient and scalable charging system. 

Key challenges include: 

• Ensuring Accurate Postpaid Billing – Postpaid services require CDRs and EDRs to be collected, processed, and rated correctly before being sent to billing systems for invoicing. 
• Preventing Revenue Leakage – Missing or delayed usage records can lead to inaccurate billing, disputes, and lost revenue. 
• Handling Batch-Based Charging at Scale – OFCS ensures large volumes of CDRs & EDRs are aggregated and processed efficiently, reducing operational overhead. 
• Managing Complex Service Scenarios – International roaming, premium services, and network slicing create diverse billing scenarios that require precise offline charging to ensure correct invoicing. 

Without a highly automated OFCS, CSPs face billing inefficiencies, revenue loss, and compliance risks. 

DigitalRoute’s OFCS eliminates these challenges by enabling automated, high-integrity offline charging that ensures all postpaid usage data is accurately captured and billed.
