Based on the ZXUN RCP (Resource Control Platform), ZTE's policy management solution implements functions of PCRF (Policy and Charging Rules Function) and PCF (Policy Control Function) in the 3GPP architecture. It can provide the unified policy and charging control for 3G/4G/5G/WiFi/IMS and other network access modes to simplify the network and save investment.
ZTE's policy management solution can support the following three types of application scenarios:
1. Providing functions such as admission control, FUP, busy/idle time control, service-based control, VIP user control, BOD, anti-bill shock, roaming control, charging control, flexible redirection, access and mobility policy control and user policy, to support data service application scenarios
2. Providing functions such as VoLTE/VoNR resource reservation, IMS emergency call, location query, charging correlation, P-CSCF disaster recovery enhancement and PCRF/PCF hot standby redundancy, to support voice service application scenarios
3. Cooperating with SCEF/NEF and exposing network capabilities such as QoS and traffic influence to 3rd party applications, to support capability exposure application scenarios
