REAL-TIME BILLING ENFORCEMENT

PCEF (Policy & Charging Enforcement Function)

Carrier policy execution node communicating over 3GPP Diameter Gx & Gy interfaces for zero-rated traffic, throttling, and prepaid credit control.

STINGRAY ECOSYSTEM Deployable on Bare-Metal & NFV

Engineered for Line-Rate Carrier Scale

PCEF provides service data flow detection, user plane traffic measurement, and policy enforcement directed by the PCRF (Policy and Charging Rules Function) and OCS (Online Charging System). It powers zero-rated social media bundles, daily data passes, and carrier billing locks.

CARRIER BENCHMARK
< 5ms

Diameter Credit-Control Request (CCR/CCA) Response Latency

Hardware Portability:
Operates on standard COTS servers (Intel Xeon / AMD EPYC), bypassing Linux kernel latency via DPDK user-space drivers.
