1. Values of NGN
NGN in 4 words…
• by Fixed
• by Mobile
• by Wireless
NGN = Broadband Managed IP Network
•

3. Next Phase of NGN Standards
Overall Requirements for the Next Phase
•
•
•
•
•
Check the interfaces of existing or expecting systems to
meet 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 SDO’s like IETF,
IEEE, ISO/IEC, etc.
Clear leadership of standards development for
convergence environment

3. Next Phase of NGN Standards
Detailed Requirements for the Next Phase
• NGN Terminals
– PC, PDA, Mobile 2G/3G Phone, PSTN Phone
– WiFi Phone, WiBro Phone, NGN Phone(?)
• Interfaces for NGN systems and their
standards
– UNI, NNI, SNI
– Interface Specification/Standards

Communications
3. Next Phase of NGN Standards
Detailed Requirements for the Next Phase
• User Interface Protocols including signaling
– UNI protocol at transport layer in general and for specific capabilities
such as multicast/broadcast, and media/processing conversion
– UNI protocol at service layer for specific applications such as
VoIP/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

4. A way to real co-ordination
Global Standards
Global Standards ≠ A Regional Standard nor ∑Regional Standards
Regional Standards = Common Global Sense + Regional Specific
