Description of the illustration http_extensionpoints.gif

This figure illustrates the four HTTP-request processing extension points; Request-Received extension, Pre-OCS extension, Post-OCS extension, and Post-OCS-BalanceQuery extension. This figure shows that the Request-Received extension processes the CDR before any rating, discounting, or alteration logic has been invoked and also it allows immediate response that bypasses the OCS completely. The Pre-OCS extension processes the ECE Usage Request payload before any rating, discounting, or alteration logic has been invoked. The Post-OCS extension processes the usage response before it is returned to the 5G client. The Post-OCS-BalanceQuery extension processes the usage response before it is returned to the 5G client.
