Signalling flows and parameter mapping for resource control
|Publication Date:||1 January 2008|
This supplement specifies the signalling flows for next generation network (NGN) resource and admission control functions (RACFs), which includes the entities: policy decision physical entity (PD-PE); transport resource control physical entity (TRC-PE); and policy enforcement physical entity (PE-PE). The various interfaces involving these entities are Rs (rcp1), Rp (rcp2), Rw (rcp3), Rc (rcp4), Rt (rcp5), Rd (rcp6), Ru and Ri. In addition, this supplement specifies the QoS parameter mapping across the various protocols for different signalling flows.
