5G Policy Overview

The 5G MATRIXX Policy Application provides the business logic and integration into a 3rd party policy control function (PCF) to support real-time policy decisions and rules. It enables your PCF to deliver flexible policy and charging control rules to your 5G network.

The 5G MATRIXX Digital Commerce Converged Charging Server (CCS) integrates policy support using the SBA Gateway and the MATRIXX Engine. MATRIXX SBA Gateway acts as the Charging Function (CHF) interfacing with external session management functions (SMFs) for policy control. The PCFs are part of your 5G network, and are external to MATRIXX Digital Commerce.

The MATRIXX CHF offers Nchf_SpendingLimitControl (N28) communication to the PCF to deliver spending limit control service that the PCF can use to obtain policy counters and subscribe to spending limit reporting.
