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.
