How it Works
This section describes how this feature works.
The cnSGW-C network function handles the change notification request using the following approach:
-
If the ULI or the UCI changes are valid in the connection request (CNREQ), the associated packet data network (PDN) is updated.
-
cnSGW-C initiates a Query URR to get the latest usage information and generates cnSGW-C CDR when:
-
ULI is modified.
-
Charging and ULI trigger is enabled.
-
For information on configuring charging, see SGW Charging Support chapter.
