Introduction of AI and machine learning

VAS Experts increased the capacity of the Network Policy and Charging Management (PCEF) system by implementing and algorithms artificial intelligence. machine learning Now PCEF with DPI and AI is a tool that makes network management adaptive, predictive, and self-decision-making based on traffic behavior analysis. The company announced this on September 11, 2025.

The integration of ML and AI into PCEF in combination with DPI allows not only to analyze the structure and behavior of packets, but also to recognize new protocols and formats, as well as identify deviations from normal network operation and early signs of attacks, including zero-day.

Based on the data collected, the system predicts load peaks - whether it is launching new games, software updates or active streaming. Analysis of historical data and behavioral patterns allows you to more accurately allocate resources and maintain a high level of quality of service even during periods of increased demand.

In addition, ML and AI provide a dynamic response to anomalies: IoT devices with non-standard behavior can be temporarily isolated, and new rules automatically apply to them without the participation of engineers.

Integration of AI and ML into PCEF means for operators a direct increase in network efficiency and risk mitigation. The system maintains a stable quality of service, blocks illegal content and prevents data leaks. Algorithms automatically optimize rules, generate reports and simplify the work of the support service, up to personalized recommendations for subscribers, "said Stanislav Beloborodov, Product Director of VAS Experts.

PCEF SCAT start-up

VAS Experts has developed and launched a product for SCAT PCEF mobile operators. The solution helps you effectively manage rates, analyze traffic, and offer customers personalized service packages. The company announced this on January 23, 2025.

PCEF (Policy and Charging Enforcement Function) enforces QoS and flexible charging policies based on different conditions according to PCRF requirements. PCEF SCAT is connected to the carrier network on the Gi/SGi interface and interacts with the following operator systems:

• Mobile network core (GGSN/PGW) via Gi/SGi interface
• PCRF Service Policy Management Module via Gx Interface
• Online charging module of subscriber traffic via Gy interface
• Subscriber Traffic Offline Charging Module via Ga/Gz Interface
• Configuration management is done via the command line (CLI) or the system web interface (Web UI)

PCEF SCAT was created to help mobile operators quickly introduce new tariffs, analyze their popularity and adapt flexibly to changes in the market. The solution integrates with PCRF, OCS and OFCS, providing support for both prepaid and postpaid subscribers, as well as corporate users and IoT devices. The use of PCEF SCAT allows operators to optimize the sale of additional services, monetize access points, improve user experience and effectively combat fraud, "said Stanislav Beloborodov, chief expert at VAS Experts.

The PCEF SCAT solution allows you to provide innovative tariff plans, control the use data and enforce policies to maintain high quality and protect revenues with any combination of access technologies. The system also generates marketing user behavior reports and provides data for. billing
