SaMOG Gateway Offline Charging
The SaMOG Gateway supports generation of CDR files for offline charging. In Offline Charging, charging information
is collected concurrently with resource usage and passed through a chain of logical charging functions. At the end of the
process, CDR files are generated by the network and transferred to the network operator's Billing Domain.

The Charging Trigger Function (CTF) generates charging events and forwards them to the Charging Data Function
(CDF). The CDF then generates CDRs and transfers it to the Charging Gateway Function (CGF). Finally, the CGF
create CDR files and forwards them to the Billing Domain.

The SaMOG Gateway integrates with the CTF and CDF functions, generates CDRs based on the triggered events, and
sends the same to the CGF over the Gz/Wz interface (using the GTPP protocol).
