OFCS
The Offline Charging System (OFCS) processes charging records generated as network services are consumed, preparing them for downstream billing. It validates and formats usage records so accurate charging data can be delivered to the Billing Domain for post-usage billing and other offline charging processes.
CSPs’ key Offline Charging challenges
01
Disparate Charging Records
Charging records from multiple network generations and service domains must be consistently processed and prepared for downstream billing.
02
Charging Record Completeness & Accuracy
Missing, duplicate, delayed or incorrectly processed charging records can result in billing errors, disputes and revenue leakage.
03
High-Volume Charging Record Processing
Large volumes of charging records must be processed reliably and efficiently without creating downstream billing bottlenecks.
04
Evolving Charging Record Complexity
5G SA, roaming, network slicing and differentiated services introduce additional charging attributes and record structures that must be accurately processed for downstream billing.
Without a highly automated OFCS, CSPs face greater risk of billing inefficiencies, revenue leakage, and difficulty meeting audit and compliance requirements.
How We Help CSPs Manage Offline Charging

Billing-Ready Charging Records
Process and format CDRs, EDRs, and other charging records from voice, data, messaging, and roaming use cases to support accurate downstream billing.
Evolving Charging Scenarios
Process and enrich offline charging records for roaming, premium services, and evolving 5G scenarios, including records with network-slice and QoS-related charging attributes where applicable.
High-Volume Offline Processing
Automate high-volume offline charging workflows, including batch-based processing, to reduce manual intervention and operational workload.
Reliable Downstream Delivery
Validate and route processed, billing-ready charging records to downstream Billing Domain systems through supported offline charging flows.
Revenue Protection
Validate, deduplicate, and consistently process charging records to reduce billing errors and revenue leakage risk.
Charging Data Traceability
Maintain consistent, traceable charging records to support billing investigations, auditability, reconciliation, and compliance processes.
