The total PCRF market is expected to grow by a compounded annual growth rate (CAGR) of 11% between 2018 and 2023 and the entire market will approach $2 billion. The PCF market, part of the new 5G core network, will mirror the deployments of core networks for standalone (SA) 5G networks. The key drivers for PCRF and PCF growth will continue to be: net increases in LTE and 5G subscriptions, growth in VoLTE and other applications that require specific quality-of-service treatment throughout the network, including network slicing in the later part of the forecast, and continued growth in sophisticated billing and charging plans, like sponsored data and content, family plans, and tiered data services.
