| Signalling flows and parameter mapping for resource control |
 |
Supplement 59 to ITU-T Q-series Recommendations specifies the signalling flows for next generation network (NGN) resource and admission control functions (RACFs), which include the entities: policy decision physical entity (PD-PE); transport resource control physical entity (TRC-PE); and policy enforcement physical entity (PE-PE). It also specifies the quality of service (QoS) parameter mapping across the various protocols for different signalling flows. |
