适用范围

This Recommendation specifies the resource and admission control functions (RACF) in support of end-to-end quality of service (QoS) and network border control (at access-core and inter-domain boundaries) in next generation networks (NGNs). The RACF is aimed at providing real-time application-driven and policy-based transport resource management for a wide range of services and for a variety of transport technologies (e.g., fixed or mobile). Services can make use of RACF whether the IP multimedia subsystem (IMS) is involved or not. This Recommendation defines the related requirements and functional architecture covering aspects such as resource reservation, admission control and gate control, network address port translation (NAPT) and firewall control, and network address translator (NAT) traversal. This Recommendation defines the related requirements and functional architecture covering aspects such as interactions with 3GPP policy control functionalities, resource and admission control between NGNs and RACF-unaware IP networks, wholesale, time-shifted TV services, QoS downgrading, mobility, resource and admission control based on user subscription profile, support of deep packet inspection (DPI), communication between RACF and management of performance measurement (MPM), policy-based charging control, and IPTV service by invitation.
