Overall Requirements for the Next Phase

3. Next Phase of NGN Standards

Check the interfaces of existing or expecting systems tomeet NGN requirements and capabilities

Find the relevant interfaces and their protocols to meet

NGN services Develop protocols at identified I/F and relevant systems

Identify how to collaborate with the other SDOs likeIETF, IEEE, ISO/IEC, etc.

Clear leadership of standards development forconvergence environment

Detailed Requirements for the Next Phase User Interface Protocols including signaling

UNI protocol at transport layer in general and for specific capabilitiessuch as multicast/broadcast, and media/processing conversion

UNI protocol at service layer for specific applications such asVoIP/MMoIP, IP TV, DMB, etc.

Protocol between transport network and transport control (RACF,NACF) Real time or End-End control Way to handle Un-controllable transport equipments

Protocol between transport control and service control Protocol to support independence of service control from transport

resources Mechanism to bind service control entities with transport control

elements like LMP (to bind the optical transmission resources from routing control

information)

Protocol between service control and application server Protocol between end user and transport control/ service control
