Abstract
A system described herein may provide a mechanism for accurately tracking data usage across multiple User Plane Function (“UPF”) devices in a telecommunications network. For example, different types of traffic may be handled by UPFs (e.g., may be dropped or forwarded), and the UPFs may be able to report the dropping of specific types of traffic, without needing to perform deep packet inspection (“DPI”). Header information may be passed from an upstream UPF to a downstream UPF with the traffic, where the header information indicates rules and/or policies that were applied by the upstream UPF. The downstream UPF may identify the rules and/or policies from the upstream UPF, and may use this information when reporting usage to a Session Management Function (“SMF”).
