What is CG (Charging Gateway function)?

Charging Gateway Function (CGF) is assisting GTP Prime protocol that is able to accept any record in any principles-based format created by the network and producing rich records in the format needed by the downstream framework. It assists in protecting investment in existing BSS/OSS frameworks by interfacing to send data to the downstream framework in the required format. It assists GTO Prime protocol, capable of changing standard format records into rich record designs needed by downstream frameworks.
